Opinion GEORGE, C. J. In this case we consider whether appellant Susann (known as Sun) Margreth Bonds voluntarily entered into a premarital agreement with respondent Barry Lamar Bonds. We conclude that the Court of Appeal erred in determining that because Sun, unlike Barry, was not represented by independent counsel when she entered into the agreement, the voluntariness of the agreement must be subjected to strict scrutiny. Instead, we determine that the circumstance that one of the parties was not represented by independent counsel is only one of several factors that must be considered in determining whether a premarital agreement was entered into voluntarily. Further, as we shall explain, we conclude that substantial evidence supports the determination of the trial court that the agreement in the present case was entered into voluntarily. I Sun and Barry met in Montreal in the summer of 1987 and maintained a relationship during ensuing months through telephone contacts. In October 1987, at Barry’s invitation, Sun visited him for 10 days at his home in Phoenix, Arizona. In November 1987, Sun moved to Phoenix to take up residence with Barry and, one week later, the two became engaged to be married. In January 1988, they decided to marry before the commencement of professional baseball’s spring training. On February 5, 1988, in Phoenix, the parties entered into a written premarital agreement in which each party waived any interest in the earnings and acquisitions of the other party during marriage. That same day, they flew to Las Vegas, and were married the following day. Each of the parties then was 23 years of age. Barry, who had attended college for three years and who had begun his career in professional baseball in 1985, had a contract to play for the Pittsburgh Pirates. His annual salary at the time of the marriage ceremony was approximately $106,000. Sun had emigrated to Canada from Sweden in 1985, had worked as a waitress and bartender, and had undertaken some training as a cosmetologist, having expressed an interest in embarking upon a career as a makeup artist for celebrity clients. Although her native language was Swedish, she had used both French and English in her employment, education, and personal relationships when she lived in Canada. She was unemployed at the time she entered into the premarital agreement. Barry petitioned for legal separation on May 27, 1994, in California, the parties then being California residents. Sun requested custody of the parties’ two children, then three and four years of age. In addition, she sought child and spousal support, attorney fees, and a determination of property rights. The petition was amended to request dissolution, and the court bifurcated the trial proceedings, first adjudicating the issue of the validity of the premarital agreement and then reaching the remaining issues involving application of the agreement to the property held by the parties and the determination of spousal and child support. Child support was awarded in the amount of $10,000 per month per child. Spousal support was awarded in the amount of $10,000 per month, to terminate December 30, 1998. Only the first issue —the validity of the premarital agreement—is before this court. Barry testified that he was aware of teammates and other persons who had undergone bitter marital dissolution proceedings involving the division of property, and recalled that from the beginning of his relationship with Sun he told her that he believed his earnings and acquisitions during marriage should be his own. He informed her he would not marry without a premarital agreement, and she had no objection. He also recalled that from the beginning of the relationship, Sun agreed that their earnings and acquisitions should be separate, saying “what’s mine is mine, what’s yours is yours.” Indeed, she informed him that this was the practice with respect to marital property in Sweden. She stated that she planned to pursue a career and wished to be financially independent. Sun knew that Barry did not anticipate that she would shoulder her living expenses while she was not employed. She was not, in fact, employed during the marriage. Barry testified that he and Sun had no difficulty communicating. Although Barry testified that he had previous experience working with lawyers in the course of baseball contract negotiations and the purchase of real property, his testimony at trial did not demonstrate an understanding of the legal fine points of the agreement. Sun’s testimony at trial differed from Barry’s in material respects. She testified that her English language skills in 1987 and 1988 were limited. Out of pride, she did not disclose to Barry that she often did not understand him. She testified that she and Barry never discussed money or property during the relationship that preceded their marriage. She agreed that she had expressed interest in a career as a cosmetologist and had said she wished to be financially independent. She had very few assets when she took up residence with Barry, and he paid for all their needs. Their wedding arrangements were very informal, with no written invitations or caterer, and only Barry’s parents and a couple of friends, including Barry’s godfather Willie Mays, were invited to attend. No marriage license or venue had been arranged in advance of their arrival in Las Vegas. Several persons testified as to the circumstances surrounding the signing of the premarital agreement. Sun testified that on the evening before the premarital agreement was signed, Barry first informed her that they needed to go the following day to the offices of his lawyers, Leonard Brown and his associate Sabinus Megwa. She was uncertain, however, whether Barry made any reference to a premarital agreement. She testified that only at the parking lot of the law office where the agreement was to be entered into did she learn, from Barry’s financial adviser, Mel Wilcox, that Barry would not marry her unless she signed a premarital agreement. She was not upset. She was surprised, however, because Barry never had said that signing the agreement was a precondition to marriage. She did not question Barry or anyone else on this point. She was under the impression that Barry wished to retain separate ownership of property he owned before the marriage, and that this was the sole object of the premarital agreement. She was unaware the agreement would affect her future and was not concerned about the matter, because she was nervous and excited about getting married and trusted Barry. Wilcox’s statement had little effect on her, because she had no question but that she and Barry were to be married the following day. Sun recalled having to hurry to arrive at the lawyers’ office in time both to accomplish their business there and make the scheduled departure of the airplane to Las Vegas so that she and Barry could marry the next day. Sun recalled that once they arrived at the lawyers’ office on February 5, 1988, she, her friend Margareta Forsberg, Barry, and Barry’s financial adviser Mel Wilcox were present in a conference room. She did not recall asking questions or her friend asking questions, nor did she recall that any changes were made to the agreement. She declared that her English language skills were limited at the time and she did not understand the agreement, but she did not ask questions of anyone other than Margareta Forsberg or ask for more time, because she did not want to miss her flight and she was focussed on the forthcoming marriage ceremony. She did not believe that Barry understood the agreement either. Forsberg was unable to assist her. Sun did not recall the lawyers telling her that she should retain her own lawyer, that they were representing Barry and not her, that the applicable community property law provided that a spouse has an interest in the earnings and in acquisitions of the other spouse during marriage, or that she would be waiving this right if she signed the agreement. The lawyers may have mentioned the possibility of her being represented by her own lawyer, but she did not believe she needed one. She did not inform anyone at the meeting that she was concerned about the agreement; the meeting and discussion were not cut short, and no one forced her to sign the agreement. Forsberg, a native of Sweden and 51 years of age at the time the agreement was signed, confirmed that she was present when Attorneys Brown and Megwa explained the agreement, that Wilcox also was present, that no changes to the agreement were made at Sun’s or Forsberg’s request, and that she had been unable to answer Sun’s questions or explain to Sun the terminology used in the agreement. She confirmed that Sun’s English was limited, that the lawyers had explained the agreement, and that Sun never stated that she was considering not signing the agreement, that she did not understand it, or that she was not signing of her own free will. Sun never said that Barry threatened her or forced her to sign, that she wanted to consult independent counsel concerning the agreement, or that she felt pressured. Forsberg understood that Brown and Megwa were Barry’s attorneys, not Sun’s. She testified that when the attorneys explained the agreement, she did not recall any discussion of Sun’s community property rights. Barry and other witnesses offered a different picture of the circumstances leading to the signing of the premarital agreement, an account found by the trial court to be more credible in material respects, as reflected in its statement of decision. Barry and his attorney, Brown, recalled that approximately two weeks before the parties signed the formal agreement, they discussed with Sun the drafting of an agreement to keep earnings and acquisitions separate. Brown testified that he told Sun at this meeting that he represented Barry and that it might be in her best interest to obtain independent counsel. Barry, Brown, and Megwa testified that Wilcox was not present at the February 5, 1988,- meeting, which lasted between one and two hours, and that at the meeting the attorneys informed Sun of her right to independent counsel. All three recalled that Sun stated she did not want her own counsel, and Megwa recalled explaining that he and Brown did not represent her. Additionally, all three recalled that the attorneys read the agreement to her paragraph by paragraph and explained it as they went through it, also informing her of a spouse’s basic community property rights in earnings and acquisitions and that Sun would be waiving these rights. Megwa recalled it was clearly explained that Barry’s income and acquisitions during the marriage would remain Barry’s separate property, and he recalled that Sun stated that such arrangements were the practice in Sweden. Furthermore, Barry and the two attorneys each confirmed that Sun and Forsberg asked questions during the meeting and were left alone on several occasions to discuss its terms, that Sun did not exhibit any confusion, and that Sun indicated she understood the agreement. They also testified that changes were made to the agreement at Sun’s behest. Brown and Megwa experienced no difficulty in communicating with Sun, found her confident and happy, and had no indication that she was nervous or confused, intimidated, or pressured. No threat was uttered that unless she signed the agreement, the wedding would be cancelled, nor did they hear her express any reservations about signing the agreement. Additionally, legal secretary Ilia Washington recalled that Wilcox waited in another room while the agreement was discussed, that Sun asked questions and that changes were made to the agreement at her behest, that Sun was informed she could secure independent counsel, that Sun said she understood the contract and did not want to consult another attorney, and that she appeared to understand the discussions and to feel comfortable and confident. The trial court observed that the case turned upon the credibility of the witnesses. In support of its determination that Sun entered into the agreement voluntarily, “free from the taint of fraud, coercion and undue influence . . . with full knowledge of the property involved and her rights therein,” the trial court made the following findings of fact: “Respondent [Sun] knew Petitioner [Barry] wished to protect his present property and future earnings. Respondent knew . . . that the Agreement provided that . . . Petitioner’s present and future earnings would remain his separate property. . . . Respondent is an intelligent woman and though English is not her native language, she was capable of understanding the discussion by Attorney Brown and Attorney Megwa regarding the terms of the agreement and the effect of the Agreement on each [party’s] rights, H[] ". . . HQ . . . Respondent was not forced to execute the document, nor did anyone threaten Respondent in any way. Respondent never questioned signing the Agreement .or requested that she not sign the Agreement. Respondent’s refusal to sign the Agreement would have caused little embarrassment to her. The wedding was a small impromptu affair that could have been easily postponed. H]] Respondent had sufficient knowledge of the nature, value and extent of the property affected by the Agreement. Petitioner fully disclosed the nature, approximate value and extent of all of his assets to Petitioner, both prior to and on the day of the execution of the agreement. HI] Respondent had sufficient knowledge and understanding of her rights regarding the property affected by the Agreement, and how the Agreement adversely affected those rights. Respondent had the opportunity to read the Agreement prior to executing it. Attorneys Brown and Megwa explained to both parties their rights regarding the property affected by the Agreement, and how the Agreement adversely affected those rights. Respondent never stated prior to execution that she did not understand the meaning of the Agreement or the explanations provided by Petitioner’s attorneys. [^] Respondent had sufficient awareness and understanding of her right to, and need for, independent counsel. Respondent also had an adequate and reasonable opportunity to obtain independent counsel prior to execution of the Agreement. Respondent was advised at a meeting with Attorney Brown at least one week prior to execution of the Agreement that she had the right to have an attorney represent her and that Attorneys Brown and Megwa represented Petitioner, not Respondent. On at least two occasions during the February 5, 1988, meeting, Respondent was told that she could have separate counsel if she chose. Respondent declined. Respondent was capable of understanding this admonition. The wedding was a small impromptu affair that could have been easily postponed.” The court also determined that Barry and Sun were not in a confidential relationship at the time the agreement was executed. The trial court also declared that pursuant to a pretrial stipulation the burden of proof rested upon Sun, but that even if the court were to place the burden of proof upon Barry, Barry had demonstrated by clear and convincing evidence “that the agreement and its execution [were] free from the taint of fraud, coercion or undue influence” and that Sun “entered the agreement with full knowledge of the property involved and her rights therein.” The Court of Appeal in a split decision reversed the judgment rendered by the trial court and directed a retrial on the issue of voluntariness. The majority stressed that Sun lacked independent counsel, determined that she had not waived counsel effectively, and concluded that under such circumstances the evidence must be subjected to strict judicial scrutiny to determine whether the agreement was voluntary. The majority asserted that Attorneys Brown and Megwa failed to explain that Sun’s interests conflicted with Barry’s, failed to urge her to retain separate counsel, and may have led Sun to believe they actually represented her interests as they explained the agreement paragraph by paragraph. The majority concluded that the trial court erred in failing to give proper weight to the circumstance that Sun was not represented by independent counsel. It asserted with regard to marital settlement agreements in dissolution actions that “the court should ‘carefully scrutinize the agreements’ when the party challenging the agreement did not have the advice of counsel [citation],” and that the same rule should apply to premarital agreements. It cited various other circumstances in the present case that, according to the majority, demonstrated a lack of voluntariness. The majority opinion pointed to Sun’s limited English language skills and lack of “legal or business sophistication,” and stated that she “received no explanation of the legal consequences to her ensuing from signing the contract” and “was told there would be ‘no marriage’ if she did not immediately sign the agreement.” It also referred to typographical errors and omissions in the agreement, the imminence of the wedding and the inconvenience and embarrassment of canceling it, Sun’s asserted lack of understanding that she was waiving her statutory right to a community property interest in Barry’s earnings, and the absence of an attorney acting as an advocate on her behalf. The dissenting justice contended that the majority had erred in failing to apply the appropriate legal standard to determine the voluntariness of the agreement and in failing to accord appropriate deference to the factual determinations of the trial court. We granted Barry’s petition for review. II We first consider whether the Court of Appeal majority applied the appropriate legal standard in resolving the question whether the premarital agreement was entered into voluntarily. We conclude it erred in holding that a premarital agreement in which one party is not represented by independent counsel should be subjected to strict scrutiny for voluntariness. Such a holding is inconsistent with Family Code section 1615, which governs the enforceability of premarital agreements. A From the inception of its statehood, California has retained the community property law that predated its admission to the Union and consistently has provided as a general rule that property acquired by spouses during marriage, including earnings, is community property. (See Fam. Code, § 760; see also former Civ. Code, § 5110, added by Stats. 1969, ch. 1608, § 8, p. 3339 and repealed by Stats. 1992, ch. 162, § 3, p. 464; Stats. 1850, ch. 103, § 2, p. 254; Stewart v. Stewart (1926) 199 Cal. 318, 321-322 [249 P. 197]; 11 Witkin, Summary of Cal. Law (9th ed. 1990) Community Property, §§ 1-3, pp. 374-377.) At the same time, applicable statutes recognized the power of parties contemplating a marriage to reach an agreement containing terms at variance with community property law. Thus in 1850, the Legislature provided that community property principles shall govern the rights of the parties “unless there is a marriage contract, containing stipulations contrary thereto.” (Stats. 1850, ch. 103, § 14, p. 255; see also former Civ. Code, § 5133, added by Stats. 1969, ch. 1608, § 8, p. 3343 [community property law governs property of husband and wife “unless there is a marriage settlement containing stipulations contrary thereto”]; former Civ. Code, § 177 (enacted in 1872); Barker v. Barker (1956) 139 Cal.App.2d 206, 212 [293 P.2d 85] [“Parties contemplating marriage may validly contract as to their property rights, both as to property then owned by them and as to property, including earnings, which may be acquired by them after marriage [citations], and the codes provide for such agreements (see [former] Civ. Code, §§ 177-181 . . .)”]; see also Fam. Code, § 1500 [“The property rights of husband and wife prescribed by statute may be altered by a premarital agreement or other marital property agreement”].) There is nothing novel about statutory provisions recognizing the ability of parties to enter into premarital agreements regarding property, because such agreements long were common and legally enforceable under English law, and have enjoyed a lengthy history in this country. In California, a premarital agreement generally has been considered to be enforceable as a contract, although when there is proof of fraud, constructive fraud, duress, or undue influence, the contract is not enforceable. (See Estate of Wamack (1955) 137 Cal.App.2d 112, 116-117 [289 P.2d 871]; La Liberty v. La Liberty (1932) 127 Cal.App. 669, 672-673 [16 P.2d 681].) The rules applicable to the interpretation of contracts have been applied generally to premarital agreements. (See Barham v. Barham (1949) 33 Cal.2d 416, 422 [202 P.2d 289]; In re Marriage of Garrity and Bishton (1986) 181 Cal.App.3d 675, 683 [226 Cal.Rptr. 485].) At one time, a premarital agreement that was not made in contemplation that the parties would remain married until death was considered to be against public policy in California and other jurisdictions (see In re Marriage of Higgason (1973) 10 Cal.3d 476, 485 [110 Cal.Rptr. 897, 516 P.2d 289]; see also Brooks v. Brooks, supra, 733 P.2d at pp. 1048-1049, fn. 4, and cases cited), but this court concluded in 1976 that the validity of a premarital agreement “does not turn on whether the parties contemplated a lifelong marriage.” (In re Marriage of Dawley (1976) 17 Cal.3d 342, 352 [131 Cal.Rptr. 3, 551 P.2d 323].) The latter opinion was in conformity with the emerging view in other jurisdictions that a premarital agreement concerning the disposition of property upon the dissolution of a marriage was not against public policy. (See Posner v. Posner (Fla. 1970) 233 So.2d 381, 385 [often cited as the seminal opinion on this issue].) Persons contemplating marriage began to enter into agreements setting out property rights in contemplation of marital dissolution—rights that differed from those that would accrue under applicable statutes—but there was some uncertainty and considerable lack of uniformity regarding the circumstances under which such agreements would be enforceable. (See 9B West’s U. Laws Ann. (1987) U. Premarital Agreement Act (1983) Prefatory Note, p. 369.) In order to encourage enforcement of such agreements on a more certain and uniform basis, while, according to the drafters of the act, retaining some “flexibility,” the Uniform Premarital Agreement Act (hereafter sometimes referred to as the Uniform Act) was promulgated in 1983. (9B West’s U. Laws Ann., supra, Uniform Act, Prefatory Note, p. 369.) In 1985, the California Legislature adopted most of the provisions of the Uniform Act. (Fam. Code § 1600 et seq. (hereafter referred to sometimes as the California Uniform Act); see former Civ. Code, § 5300 et seq., added by Stats. 1985, ch. 1315, § 3, p. 4582; Sen. Com. on Judiciary, Rep. on Sen. Bill No. 1143 (1985-1986 Reg. Sess.) p. 2; Assem. 3d reading digest of Sen. Bill No. 1143 (1985-1986 Reg. Sess.) as amended Aug. 28, 1985, p. 3.) The only provisions of the Uniform Act omitted by the California Legislature were those permitting the parties to waive the right to spousal support and limiting the right to waive spousal support where such a waiver would result in a spouse’s becoming a public charge. (Compare Fam. Code, § 1600 et seq. with 9B West’s U. Laws Ann., supra, Uniform Act, § 3, subd. (a)(4), p. 373; id.., § 6, subd. (b), p. 376.) This legislative omission is examined in today’s decision in In re Marriage of Pendleton & Fireman (2000) 24 Cal.4th 39 [99 Cal.Rptr.2d 278, 5 P.3d 839], but is not involved in the present case. B The California enactment, like the Uniform Act, sets out the law of premarital agreements, including such matters as the nature of property subject to such agreements, the requirement of a writing, and provision for amendments. (See Fam. Code, §§ 1611-1614.) Section 1615 of the Family Code, like section 6 of the Uniform Act, regulates the enforceability of such agreements. It provides in pertinent part: “(a) A premarital agreement is not enforceable if the party against whom enforcement is sought proves either of the following: [f] (1) That party did not execute the agreement voluntarily. [H] (2) The agreement was unconscionable when it was executed and, before execution of the agreement, all of the following applied to that party: [ft] (A) That party was not provided a fair and reasonable disclosure of the property or financial obligations of the other party, ftj] (B) That party did not voluntarily and expressly waive, in writing, any right to disclosure of the property or financial obligations of the other party beyond the disclosure provided. [^] (C) That party did not have, or reasonably could not have had, an adequate knowledge of the property or financial obligations of the other party.” Pursuant to Family Code section 1615, a premarital agreement will be enforced unless the party resisting enforcement of the agreement can demonstrate either (1) that he or she did not enter into the contract voluntarily, or (2) that the contract was unconscionable when entered into and that he or she did not have actual or constructive knowledge of the assets and obligations of the other party and did not voluntarily waive knowledge of such assets and obligations. In the present case, the trial court found no lack of knowledge regarding the nature of the parties’ assets, a necessary predicate to considering the issue of unconscionability, and the Court of Appeal accepted the trial court’s determination on this point. We do not reconsider this factual determination, and thus the question of unconscionability is not before us. We also do not review the determination of the Court of Appeal that California law, rather than Arizona law, governs the enforceability of this agreement, and we express no opinion on this point. Thus, the only issue we face concerns the trial court’s determination that Sun entered into the agreement voluntarily. Neither the article of the Family Code in which section 1615 is located, nor the Uniform Act, defines the term “voluntarily.” Certain rules of construction guide us in our interpretation of this term. “We begin with the fundamental rule that a court ‘should ascertain the intent of the Legislature so as to effectuate the purpose of the law.’ [Citation.] In determining such intent ‘[t]he court turns first to the words themselves for the answer.’ [Citation].” (Moyer v. Workmen’s Comp. Appeals Bd. (1973) 10 Cal.3d 222, 230 [110 Cal.Rptr. 144, 514 P.2d 1224].) “‘Words used in a statute . . . should be given the meaning they bear in ordinary use.’ ” (Wilcox v. Birtwhistle (1999) 21 Cal.4th 973, 977 [90 Cal.Rptr.2d 260, 987 P.2d 727].) If the language reasonably may be interpreted in more than one way, we may consult extrinsic aids to determine the intent of the Legislature. (Ibid.) Courts frequently consult dictionaries to determine the usual meaning of words. (Romano v. Rockwell Internal., Inc. (1996) 14 Cal.4th 479, 493 [59 Cal.Rptr.2d 20, 926 P.2d 1114]; Moyer v. Workmen’s Comp. Appeals Bd., supra, 10 Cal.3d at pp. 230-231.) Black’s Law Dictionary defines “voluntarily” as “Done by design .... Intentionally and without coercion.” (Black’s Law Diet. (6th ed. 1990) p. 1575.) The same source defines “voluntary” as “Proceeding from the free and unrestrained will of the person. Produced in or by an act of choice. Resulting from free choice, without compulsion or solicitation. The word, especially in statutes, often implies knowledge of essential facts.” (Ibid.) The Oxford English Dictionary defines “voluntarily” as “[o]f one’s own free will or accord; without compulsion, constraint, or undue influence by others; freely, willingly.” (19 Oxford English Diet. (2d ed. 1989) p. 753.) To the extent it is unclear on the face of the statute what was intended by the Legislature in employing the term “voluntarily,” we consult the history of the statute and consider its general intent in order to determine the sense in which the Legislature used the term. (See People v. Cruz (1996) 13 Cal.4th 764, 773-774 & fn. 5 [55 Cal.Rptr.2d 117, 919 P.2d 731]; Moyer v. Workmen’s Comp. Appeals Bd., supra, 10 Cal.3d at p. 232 [meaning of the term “voluntary” is construed in a manner designed to carry out the apparent intent of the workers’ compensation law].) The debate that preceded the adoption of the Uniform Act indicated a basic disagreement between those commissioners at the National Conference of Commissioners on Uniform State Laws who placed the highest value on certainty in enforcement of premarital agreements and the vocal minority of commissioners who urged that such contracts routinely should be evaluated for substantive fairness at the time of enforcement. (See National Conference of Commissioners on Uniform State Laws, Proceedings in Committee of the Whole, U. Premarital Agreement Act (July 23-26, 1983) pp. 49-97 (Proceedings, Uniform Act).) Indeed, over sharp and repeated objection from commissioners of the minority view, eventually it was settled that the party against whom enforcement of a premarital agreement was sought only could raise the issue of unconscionability, that is, the substantive unfairness of an agreement, if he or she also could demonstrate lack of disclosure of assets, lack of waiver of disclosure, and lack of imputed knowledge of assets. The language adopted was intended to enhance the enforceability of premarital agreements and to convey the sense that an agreement voluntarily entered into would be enforced without regard to the apparent unfairness of its terms, as long as the objecting party knew or should have known of the other party’s assets, or voluntarily had waived disclosure. (Proceedings, Uniform Act, supra, pp. 52, 54, 75, 76, 80, 100, 101.) The commissioners, however, did not supply a definition of the term “voluntarily,” nor was there much discussion of the term. We find an indication of the commissioners’ understanding of the term in their official comment to the enforcement provision of the Uniform Act, stating that the conditions to enforcement “are comparable to concepts which are expressed in the statutory and decisional law of many jurisdictions.” (9B West’s U. Laws Ann., supra, Uniform Act, com. to § 6, p. 376.) In support of this statement, the comment cites cases from various jurisdictions examining the voluntariness of premarital agreements. These cases vary in their formal approach to the problem—some engage in a presumption of undue influence and place the burden of proof on the party seeking to enforce the agreement (see Lutgert v. Lutgert (Fla.Dist.Ct.App. 1976) 338 So.2d 1111, 1113-1117), while some place the burden of proof on the person challenging the agreement. (In re Kaufmann’s Estate (1961) 404 Pa. 131 [171 A.2d 48, 50-51].) In the majority of these cases, however, the question is viewed as one involving such ordinary contract defenses as fraud, undue influence, or duress, along with some examination of the parties’ knowledge of the rights being waived, or at least knowledge of the intent of the agreement. These cases demonstrate the commissioners’ belief that a number of factors are relevant to the issue of voluntariness. In considering defenses proffered against enforcement of a premarital agreement, the court should consider whether the evidence indicates coercion or lack of knowledge —just as would be suggested by the dictionary definitions of voluntariness noted above. Specifically, the cases cited in the comment to the enforcement provision of the Uniform Act direct consideration of the impact upon the parties of such factors as the coercion that may arise from the proximity of execution of the agreement to the wedding, or from surprise in the presentation of the agreement; the presence or absence of independent counsel or of an opportunity to consult independent counsel; inequality of bargaining power—in some cases indicated by the relative age and sophistication of the parties; whether there was full disclosure of assets; and the parties’ understanding of the rights being waived under the agreement or at least their awareness of the intent of the agreement. The cases cited in the comment to the enforcement provision of the Uniform Act indicate that the commissioners considered that the voluntariness of a premarital agreement may turn in part upon whether the agreement was entered into knowingly, in the sense that the parties understood the terms or basic effect of the agreement. (See Hafner v. Hafner, supra, 295 N.W.2d at pp. 571-572 [objecting party understood purpose of the agreement]; Del Vecchio v. Del Vecchio, supra, 143 So.2d at p. 21 [noting that the party challenging the agreement had some understanding of the marital rights being waived]; In re Marriage of Coward, supra, 582 P.2d at pp. 835-836 [noting objecting party’s awareness of the intent of the agreement].) A premarital agreement often contains at least some hallmarks of a waiver, in that it may bind a person to forgo important rights secured by community property law—rights that in the absence of an agreement would vest automatically upon marriage. (See Del Vecchio v. Del Vecchio, supra, 143 So.2d at p. 20; see also Estate of Schwartz (1947) 79 Cal.App.2d 308, 310 [179 P.2d 868] [examining a premarital agreement for proper waiver of marital rights]; In re Marriage of Spiegel (Iowa 1996) 553 N.W.2d 309, 315 [drawing the same analogy to the waiver doctrine in examining the voluntariness of premarital agreements]; Younger, Perspectives on Antenuptial Agreements, supra, 40 Rutgers L.Rev. at p. 1078 [same].) We observe that the factors relevant to the voluntariness of a waiver generally depend upon the statutory scheme involved, and most frequently it is required that a waiver be entered into with knowledge of the effect of the agreement. (See Moyer v. Workmen’s Comp. Appeals Bd., supra, 10 Cal.3d 222.) Similarly, the cases cited in the comment to the enforcement section (§ 6) of the Uniform Act indicate that the parties’ general understanding of the effect of the agreement constitutes a factor for the court to consider in determining whether the parties entered into the agreement voluntarily. The commissioners’ debate over the problem of unconscionability throws further light on their view of the voluntariness requirement, which, as noted, did not receive much explicit discussion. Those taking the minority view noted with concern that the proposed Uniform Act would enforce agreements that might be declared void as unconscionable under the Uniform Commercial Code, because the Uniform Act precluded consideration of the substantive fairness of the agreement unless the party challenging the agreement also could prove lack of notice of the other party’s assets and obligations. Commissioners who valued substantive fairness over certainty of enforcement urged, for example, that if a premarital agreement waiving property rights is entered into between a pregnant teenager—who wishes to ensure the legitimacy of her child—and an older man, the agreement should be subject to searching scrutiny for unconscionability; those taking the majority position countered that the requirement that the contract be entered into voluntarily provided adequate protection to the weaker party. (Proceedings, Uniform Act, supra, pp. 71-73.) In addition, it was clear from their discussion that the commissioners anticipated that such defenses as lack of capacity, fraud, duress, and undue influence would apply in determining the voluntariness of the agreement. (Id. p. 131.) In sum, it is clear from the cases cited in the comment to the enforcement section of the Uniform Act and from the record of the proceedings of the National Conference of Commissioners on Uniform State Laws that the commissioners intended that the party seeking to avoid a premarital agreement may prevail by establishing that the agreement was involuntary, and that evidence of lack of capacity, duress, fraud, and undue influence, as demonstrated by a number of factors uniquely probative of coercion in the premarital context, would be relevant in establishing the involuntariness of the agreement. Not only did the commissioners intend that the above factors be considered in determining whether a premarital agreement was entered into voluntarily, but the same intention safely may be attributed to the California Legislature, because an examination of the history of the enactment of Family Code section 1615 in California indicates that the Legislature adopted the views of the commissioners in all respects relevant to the present discussion. Decisions interpreting the enforcement provision of the Uniform Act in other jurisdictions also refer to such factors as inequality of bargaining power, coercion arising from circumstances peculiar to an imminent wedding, the absence of independent counsel for one party, and the parties’ knowledge of the purpose of the agreement. The factors we have identified also are in most respects consistent with recent non-Uniform Act cases in other jurisdictions that examine what often is termed the procedural fairness of premarital agreements. These factors also are consistent with the circumstances previously considered in this state, prior to California’s adoption of the Uniform Act, in connection with the issue of the voluntariness of a premarital agreement. In In re Marriage of Dawley, supra, 17 Cal.3d 342, for example, we rejected the wife’s claim that a premarital agreement waiving community property rights had been obtained through undue influence, pointing out that in the particular case the pressure to marry created by an unplanned pregnancy fell equally on both the parties, that both parties were educated and employed, and that the party challenging the agreement did not rely upon the other party’s advice, but consulted her own attorney. (Id. at p. 355 and fn. 8; see also Estate of Cantor (1974) 39 Cal.App.3d 544, 548-549 [114 Cal.Rptr. 160] [finding that the party disputing a premarital agreement made a knowing waiver of his marital rights]; La Liberty v. La Liberty, supra, 127 Cal.App. at pp. 673-674 [rejecting lack of independent counsel as a basis for rescission, given the parties’ apparent understanding of the meaning of the premarital agreement].) We have considered the range of factors that may be relevant to establish the involuntariness of a premarital agreement in order to consider whether the Court of Appeal erred in according such great weight to one factor—the presence or absence of independent counsel for each party. As we shall explain, we do not believe that the terms or history of section 1615 of the Family Code support the conclusion of the Court of Appeal majority that a premarital agreement should be subjected to strict scrutiny for voluntariness in the absence of independent counsel for the less sophisticated party or of an assertedly effective and knowing waiver of counsel comparable to that occurring in the criminal law setting (and potentially also requiring an offer by the represented party to pay for independent counsel for the other party). In the official comment to the Uniform Act, the commissioners stated: “Nothing in [the enforcement section] makes the absence of assistance of independent legal counsel a condition for the unenforceability of a premarital agreement. However, lack of that assistance may well be a factor in determining whether the conditions stated in [the section] may have existed [citation].” (See 9B West’s U. Laws Ann., supra, Uniform Act, com. to § 6, p. 377.) It is clear from the history of the Uniform Act that the commissioners rejected the view that independent counsel was essential to the enforceability of premarital agreements. Although the proposed Uniform Act initially contained a proviso stating that premarital agreements were presumptively valid unless the party against whom enforcement was sought was not represented by independent legal counsel or there was not full disclosure, the commissioners eventually removed any reference to independent counsel. (Proceedings, Uniform Act, supra, pp. 3-4.) A commissioner explained the action of the executive committee in removing the proviso: “We feel that, certainly, that representation would be a factor in determining whether the party acted voluntarily and knowingly. We do not believe, however, that legal representation alone would be a desirable basis for enforcement.” {Ibid., italics added.) An amendment was proposed to restore the omitted provision, but it was rejected with the comment that “the legislatures of the states ought [not] to be making the rights of people dependent upon whether or not they have lawyers,” and the observation that such a rule would not reduce litigation but instead would transfer the litigation to malpractice actions. (Proceedings, Uniform Act, supra, pp. 61-62.) Further, in the comment to the enforcement section of the Uniform Act, the commissioners cited cases that discussed the presence or absence of independent counsel, or at least a reasonable opportunity to consult independent counsel, as simply a factor to consider in determining the voluntariness of the agreement. (See Lutgert v. Lutgert, supra, 338 So.2d at pp. 1115-1117 [among other coercive circumstances, the prospective wife had no opportunity to consult independent counsel, and her conversation with the prospective husband’s attorney did not result in any amendment of the agreement]; Hafner v. Hafner, supra, 295 N.W.2d at pp. 571-572 [the prospective wife did not have independent counsel, but the agreement was enforceable largely because she understood its purpose]; Del Vecchio v. Del Vecchio, supra, 143 So.2d at pp. 19-20 [it is preferable, but not required, that each party have independent counsel]; In re Marriage of Coward, supra, 582 P.2d at p. 836 [the prospective wife’s opportunity to consult independent counsel and the advice of the prospective husband’s attorney that she do so were factors in support of the enforcement of the premarital agreement, along with the circumstance that the arrangement had been discussed over a period of time, and in view of the prospective wife’s knowledge of the business world and of the assets involved, and her clear understanding of the intent of the agreement]; Matter of Estate ofLebsock, supra, 618 P.2d at p. 686 [trial court correctly refused to instruct the jury that the agreement was invalid unless the prospective wife had independent counsel]; see also Annot. (1987) 53 A.L.R.4th 85, 106-134 [collecting cases analyzing presence of counsel as a factor in determining enforceability of premárital agreements].) This is consistent with case law in California before its enactment of the Uniform Act. (La Liberty v. La Liberty, supra, 127 Cal.App. at pp. 673-674.) As noted, few state courts have interpreted their own versions of the Uniform Act, but one court that has considered under the act the relationship of independent counsel to the question of voluntariness is the Supreme Court of North Dakota. That court, reversing the grant of summary judgment in favor of heirs seeking enforcement of a premarital agreement in which the parties waived their share in the other party’s estate, determined that issues of fact remained regarding the voluntariness of the wife’s endorsement of the premarital agreement. Specifically, the court noted a factual dispute as to whether the wife adequately was advised to obtain independent counsel. It observed that under North Dakota law, the parties were in a confidential relationship and, observing that the state has an interest in every marriage contract, concluded: “We agree with the view that lack of adequate legal advice to a prospective spouse to obtain independent counsel is a significant factual factor in weighing the voluntariness of a premarital agreement, [ft] Indeed, adequate legal representation will often be the best evidence that a spouse signed a premarital agreement knowledgeably and voluntarily.” (Matter of Estate of Lutz, supra, 563 N.W.2d at p. 98.) But even the North Dakota court acknowledged that no state has made the presence of independent counsel a prerequisite to enforceability. (Id. at p. 97.) The Rhode Island Supreme Court has determined that independent counsel is not required for enforcement of premarital agreements under the Uniform Act. (Penhallow v. Penhallow, supra, 649 A.2d at p. 1022; see also Marsh v. Marsh, supra, 949 S.W.2d at pp. 740-741 [lack of independent counsel is not dispositive under the Uniform Act; disadvantaged spouse had been advised to seek separate counsel]; Lebeck v. Lebeck, supra, 881 P.2d at p. 734 [one factor in favor of enforcement was review of agreement by independent counsel].) It seems evident that the commissioners who enacted the Uniform Act intended that the presence of independent counsel (or a reasonable opportunity to consult counsel) should be merely one factor among several that a court should consider in examining a challenge to the voluntariness of a premarital agreement. Moreover, the overall purpose of the Uniform Act was to enhance the enforceability of premarital agreements, a goal that would not be furthered if agreements were presumed to be of doubtful voluntariness unless both parties were represented by independent counsel. When we also consider the circumstance that in a majority of dissolution cases in California at least one of the two parties apparently is not represented by counsel (Judicial Council of Cal., Ann. Rep. (1998) State Court Outlook, p. 40), it seems unlikely that our Legislature intended that the voluntariness of a premarital agreement should be subjected to strict scrutiny unless each party were represented by independent counsel or an unrepresented party had entered into a formal knowing waiver of counsel comparable to that required in the criminal law setting, as the Court of Appeal holding apparently would require. We also note that in those instances in which the Legislature has intended that the presence of independent counsel should be a critical factor in the enforceability of an agreement, it has explicitly so provided. When, for example, by an agreement entered into either before or during marriage, a person waives his or her statutory inheritance rights as a surviving spouse, the waiver generally is enforceable unless the surviving spouse proves that he or she did not obtain a fair disclosure of the property involved or that “[t]he surviving spouse was not represented by independent legal counsel at the time of signing of the waiver.” (Prob. Code, § 143, subd. (a)(2).) Again, such a requirement does not appear in the California Uniform Act. Finally, and perhaps most significantly, the rule created by the Court of Appeal would have the effect of shifting the burden of proof on the question of voluntariness to the party seeking enforcement of the premarital agreement, even though the statute expressly places the burden upon the party challenging the voluntariness of the agreement. Because the commissioners and our Legislature placed the burden of proof of involuntariness upon the party challenging a premarital agreement, it seems obvious that the party seeking enforcement should not be required to prove that the absence of any factor tending to establish voluntariness did not render the agreement involuntary—the inevitable result were we to adopt the strict scrutiny standard suggested by the Court of Appeal. We conclude that although the ability of the party challenging the agreement to obtain independent counsel is an important factor in determining whether that party entered into the agreement voluntarily, the Court of Appeal majority erred in directing trial courts to subject premarital agreements to strict scrutiny where the less sophisticated party does not have independent counsel and has not waived counsel according to exacting waiver requirements. C Although we agree with Barry that the lack of independent counsel for each party cannot alter the burden of proof that, by operation of statute, rests upon the party challenging the validity of the premarital agreement, we also agree with the Court of Appeal majority that considerations applicable in commercial contexts do not necessarily govern the determination whether a premarital agreement was entered into voluntarily. Some of the commissioners debating the Uniform Act appeared to equate a premarital agreement with a commercial contract, and one court has emphasized that both parties contemplating marriage possess freedom of contract, which should not be restricted except as it would be in the context of a commercial contract. (Simeone v. Simeone (1990) 525 Pa. 392 [581 A.2d 162, 165-166] [not interpreting the Uniform Act].) Even apart from the circumstance that there is no statutory requirement that commercial contracts be entered into voluntarily as that term is used in Family Code section 1615, we observe some significant distinctions between the two types of contracts. A commercial contract most frequently constitutes a private regulatory agreement intended to ensure the successful outcome of the business between the contracting parties—in essence, to guide their relationship so that the object of the contract may be achieved. Normally, the execution of the contract ushers in the applicability of the regulatory scheme contemplated by the contract and the endeavor that is the object of the contract. As for a premarital agreement (or clause of such an agreement) providing solely for the division of property upon marital dissolution, the parties generally enter into the agreement anticipating that it never will be invoked, and the agreement, far from regulating the relationship of the contracting parties and providing the method for attaining their joint objectives, exists to provide for eventualities that will arise only if the relationship founders, possibly in the distant future under greatly changed and unforeseeable circumstances. Furthermore, marriage itself is a highly regulated institution of undisputed social value, and there are many limitations on the ability of persons to contract with respect to it, or to vary its statutory terms, that have nothing to do with maximizing the satisfaction of the parties or carrying out their intent. Such limitations are inconsistent with the freedom-of-contract analysis espoused, for example, by the Pennsylvania Supreme Court. (See Simeone v. Simeone, supra, 581 A.2d at p. 165.) We refer to rules establishing a duty of mutual financial support during the marriage (Fam. Code, § 720) and prohibiting agreements in derogation of the duty to support a child of the marriage (Fam. Code, §§ 1612, subd. (b), 3900-3901; Armstrong v. Armstrong (1976) 15 Cal.3d 942, 947 [126 Cal.Rptr. 805, 544 P.2d 941]; In re Marriage of Buzzanca (1998) 61 Cal.App.4th 1410, 1426-1427, fn. 17 [72 Cal.Rptr.2d 280, 77 A.L.R.5th 775]); the unenforceability of a promise to marry (Civ. Code, § 43.5, subd. (d); Askew v. Askew (1994) 22 Cal.App.4th 942, 954-957 [28 Cal.Rptr.2d 284] [tracing the history of the rule that breach of a promise to marry does not give rise to an action in contract or tort]); the circumstance that a party may abandon the marriage unilaterally under this state’s no-fault laws; and the pervasive state involvement in the dissolution of marital status, the marriage contract, and the arrangements to be made for the children of the marriage—even without consideration of the circumstance that marriage normally lacks a predominantly commercial object. We also observe that a premarital agreement to raise children in a particular religion is not enforceable. (In re Marriage of Weiss (1996) 42 Cal.App.4th 106, 113-115 [49 Cal.Rptr.2d 339].) We note, too, that there is authority—as conceded by the commissioners who considered the Uniform Act—to the effect that a contract to pay a spouse for personal services such as nursing cannot be enforced, despite the undoubted economic value of the services (see Borelli v. Brusseau (1993) 12 Cal.App.4th 647, 651-654 [16 Cal.Rptr.2d 16]; see also Silbaugh, Marriage Contracts and the Family Economy (1998) 93 N.W.U. L.Rev. 65, 123 [most jurisdictions will not enforce agreements with respect to personal services rendered during marriage]; Note, Planning for Love: The Politics of Prenuptial Agreements, supra, 49 Stan. L.Rev. at p. 900 [same]). These limitations demonstrate further that freedom of contract with respect to marital arrangements is tempered with statutory requirements and case law expressing social policy with respect to marriage. There also are obvious differences between the remedies that realistically may be awarded with respect to commercial contracts and premarital agreements. Although a party seeking rescission of a commercial contract, for example, may be required to restore the status quo ante by restoring the consideration received, and a party in breach may be required to pay damages, the status quo ante for spouses cannot be restored to either party, nor are damages contemplated for breach of the marital contract. In any event, the suggestion that commercial contracts are strictly enforced without regard to the fairness or oppressiveness of the terms or the inequality of the bargaining power of the parties is anachronistic and inaccurate, in that claims such as duress, unconscionability, and undue influence turn upon the specific context in which the contract is formed. (See Bix, Bargaining in the Shadow of Love: The Enforcement of Premarital Agreements and How We Think About Marriage (1998) 40 Wm. & Mary L.Rev. 145, 163, 182, 188, 205; see also Atwood, Ten Years Later: Lingering Concerns About the Uniform Premarital Agreement Act (1993) 19 J. Legis. 127, 146.) We also have explained generally that we believe the reference to voluntariness in the Uniform Act was intended to convey an element of knowing waiver that is not a consistent feature of commercial contract enforcement. Further, although the Uniform Act contemplated that contract defenses should apply, in the sense that an agreement should be free from fraud (including constructive fraud), duress, or undue influence, it is clear from the debate of the commissioners who adopted the Uniform Act and the cases cited in support of the enforcement provision of the Uniform Act that subtle coercion that would not be considered in challenges to ordinary commercial contracts may be considered in the context of the premarital agreement. (See, e.g., Lutgert v. Lutgert, supra, 338 So.2d at pp. 1113-1116 [agreement presented too close to the wedding, with passage booked on an expensive cruise].) The obvious distinctions between premarital agreements and ordinary commercial contracts lead us to conclude that factual circumstances relating to contract defenses (see Civ. Code, § 1567) that would not necessarily support the rescission of a commercial contract may suffice to render a premarital agreement unenforceable. The question of voluntariness must be examined in the unique context of the marital relationship. (See Brandt, The Uniform Premarital Agreement Act and the Reality of Premarital Agreements in Idaho (1997) 33 Idaho L.Rev. 539, 546-547, 562-564; Younger, Perspectives on Antenuptial Agreements: An Update (1992) 8 J. Am. Acad. Matrim. Law. 1, 19-20; Younger, Perspectives on Antenuptial Agreements, supra, 40 Rutgers L.Rev. at p. 1075; see also ALI, Principles of the Law of Family Dissolution: Analysis and Recommendations (Tent. Draft No. 4, Apr. 10, 2000) § 7.02, corns, (a), pp. 90-91, (c), pp. 92-94; id., § 7.05, com. (b), pp. 100-101; id., § 7.07, com. (b), pp. 132-134.) On the other hand, we do not agree with Sun and the Court of Appeal majority that a premarital agreement should be interpreted and enforced under the same standards applicable to marital settlement agreements. First, although persons, once they are married, are in a fiduciary relationship to one another (Fam. Code, § 721, subd. (b)), so that whenever the parties enter into an agreement in which one party gains an advantage, the advantaged party bears the burden of demonstrating that the agreement was not obtained through undue influence (In re Marriage of Haines (1995) 33 Cal.App.4th 277, 293 [39 Cal.Rptr.2d 673]), a different burden applies under the Uniform Act in the premarital setting. Even when the premarital agreement clearly advantages one of the parties, the party challenging the agreement bears the burden of demonstrating that the agreement was not entered into voluntarily. Further, under the Uniform Act, even when there has been a failure of disclosure, the statute still places the burden upon the party challenging the agreement to prove that the terms of the agreement were unconscionable when executed, rather than placing the burden on the advantaged party to demonstrate that the agreement was not unconscionable. Thus the terms of the act itself do not support the Court of Appeal’s conclusion that the Legislature intended that premarital agreements should be interpreted in the same manner as agreements entered into during marriage. In particular, we believe that both the Court of Appeal majority and Sun err to the extent they suggest that the Uniform Act or its California analog established that persons who enter into premarital agreements must be presumed to be in a confidential relationship, a status that would give rise to the fiduciary duties between spouses expressly established by section 721 of the Family Code. California law prior to the enactment of the Uniform Act was to the contrary (see In re Marriage of Dawley, supra, 17 Cal.3d at p. 355 [persons entering into prenuptial agreement are not presumed to be in a confidential relationship]), and we discern nothing in the Uniform Act suggesting that its adoption in California was intended to overrule our earlier decision. The primary consequences of designating a relationship as fiduciary in nature are that the parties owe a duty of full disclosure, and that a presumption arises that a party who owes a fiduciary duty, and who secures a benefit through an agreement, has done so through undue influence. (See 1 Witkin, Summary of Cal. Law (9th ed.1987) Contracts, §§ 425, 426, pp. 381-383; see also Civ. Code, § 1575.) For example, a transaction in which an attorney gains an advantage over his or her client “is presumptively invalid, and the attorney must show not only that it was fair, but that the client was fully informed of all facts necessary to enable him to deal at arm’s length.” (1 Witkin, Summary of Cal. Law, supra, Contracts, § 425, pp. 381-382, italics omitted.) It long has been the rule that “[w]hen an interspousal transaction advantages one spouse, ‘[t]he law, from considerations of public policy, presumes such transactions to have been induced by undue influence.’ ” (In re Marriage of Haines, supra, 33 Cal.App.4th at p. 293, quoting Brison v. Brison (1888) 75 Cal. 525, 529 [17 P. 689].) California law also recognizes a lesser degree of confidential relationship that may arise, for example, between family members and between friends. (See 1 Witkin, Summary of Cal. Law, supra, Contracts, § 427, pp. 383-384.) In such cases “mere lack of independent advice is not sufficient to raise a presumption of undue influence or of constructive fraud, even when the consideration appears inadequate. But when to these factors is added some other such as great age, weakness of mind, sickness or other incapacity, the presumption arises, and the burden is on the other party to show that no oppression took place.” (Ibid., italics in original; see also Tyler v. Children’s Home Society (1994) 29 Cal.App.4th 511, 550 [35 Cal.Rptr.2d 291].) In the Dawley case, we found substantial evidence to support an implied finding that an agreem
