¶1 — Gloria Bernard filed for dissolution from Thomas Bernard.1 We are asked to determine the enforceability of their prenuptial agreement. We hold the agreement is not enforceable because it is substantively and procedurally unfair. We affirm Gloria’s award of attorney fees and costs.
FACTS AND PROCEDURAL HISTORY
¶2 In 1995 Thomas hired Gloria to be the operations manager for Bernard Development Company. In late 1998, after the death of Thomas’s first spouse, Thomas and Gloria began dating. Thomas asked Gloria to marry him but informed her he would require a prenuptial agreement because of the disparity in their relative wealth. At the time of their engagement, Thomas was 55 and a successful real estate developer with a net worth of approximately $25 million; Gloria was 49, held undergraduate and master’s degrees in business administration, and had a net worth of approximately $8,000. The events surrounding the signing of the prenuptial agreement and its amendment are the subject of this litigation.
¶3 In January 2000, Thomas and his longtime attorney, Richard Keefe, began working on the prenuptial agree*899ment. Thomas and Keefe repeatedly advised Gloria to obtain independent counsel but did not provide her with a draft of the proposed agreement. Lacking a draft, Gloria took no action to obtain representation. On May 24, Keefe prepared a prenuptial checklist for Thomas and Gloria and encouraged Gloria to obtain counsel. He provided her with the names of three attorneys but did not provide her with a draft agreement. On June 8, Keefe again encouraged Gloria to obtain independent representation, resending the prenuptial checklist. Gloria still did not have a draft of the agreement, however, and did not consult counsel at that time. Not until June 20, 18 days before the wedding, did Gloria receive a draft of the prenuptial agreement.
¶4 On July 5, Gloria met with Marshall Gehring, an attorney experienced in prenuptial negotiations. That evening Gehring received a working draft of the prenuptial agreement from Keefe. It was substantially different from the draft Keefe gave to Gloria on June 20.
¶5 Gehring testified at trial that he did not have sufficient time to conduct a full review of the agreement or draft a counteragreement. Instead, in a letter to Gloria dated July 7, the day before the wedding, he identified five areas of major concern with the prenuptial agreement. He indicated in his letter that he had additional minor concerns but did not specify what those were. Gehring’s letter recommended that Gloria negotiate some kind of additional written instrument to address the concerns he outlined. In testimony, Gehring agreed that he had time to only “hit the high points” in his letter and said he would have reviewed the agreement “page by page” if he had been given more time. He further testified that during the short time he had to review the agreement, it was very difficult to talk directly with Gloria, as she was busy with guests, wedding details, and honeymoon preparations.
¶6 In addition, Thomas testified that he would have called off the wedding on its eve, or even the day of, had Gloria not signed the prenuptial agreement. Gloria testified *900that she believed Thomas would not have married her if she had refused to sign the agreement.
¶7 Gloria signed the prenuptial agreement the day before the wedding, on July 7, with the understanding that it would be amended. Thomas and Gloria’s wedding took place at the Seattle Tennis Club on July 8 and included approximately 200 guests, some of whom had come from out of town.
¶8 Gloria and Thomas signed a “side letter” on the day of the wedding, agreeing to renegotiate the five areas of major concern Gehring noted in his July 7 letter. Both Gloria and Gehring testified that they believed the negotiations that followed the side letter were limited to the five areas identified by Gehring. Report of Proceedings (RP) (Sept. 6, 2005) at 112;2 RP (Sept. 12, 2005) at 17.3 The side letter required the anticipated amendment to be finalized no later than October 7, 2000, but the amendment would not be finalized until August 28, 2001. When it was eventually finalized, the amendment ratified the original prenuptial agreement and altered several provisions in accordance with each of Gehring’s concerns.
¶9 Gloria filed for dissolution on February 4, 2005. Thomas demanded arbitration under the terms of the prenuptial agreement. Gloria moved for summary judgment, challenging the enforceability of the prenuptial agreement.4 The trial court bifurcated its analysis of the enforceability of the prenuptial agreement.
*901¶10 The court determined that the prenuptial agreement, as amended, was substantively unfair as a matter of law. The court directed a trial on the question of procedural fairness. After a four day trial, the court found the prenuptial agreement, as amended, was procedurally unfair. First, the court found that the draft sent to. Gehring on July 5 was substantially different from the version Gloria received on June 20. The court further found that Gloria and Gehring received the revised draft of the agreement only a few days before the wedding, “too late to provide time for meaningful negotiation and full advise [sic].” Clerk’s Papers (CP) at 1814. The trial court also found that “[b]ecause of the impending wedding [Gloria] was faced with the choice of the humiliation of calling off a wedding or signing a substantively unfair document.” CP at 1816. Next, the court found the subsequent amendment did not cure the procedural defects of the original agreement because the terms of the side letter restricted the scope of renegotiation. Id. Accordingly, “[a]s the scope of the negotiations allowed by the ‘side letter’ were so specifically limited, the fact that there was sufficient time for independent review and for the advice of counsel was insufficient to cure the defects of the first agreement.” Id. The trial court concluded that the agreement lacked procedural fairness.
¶11 Division One of the Court of Appeals affirmed. In re Marriage of Bernard, 137 Wn. App. 827, 155 P.3d 171 (2007). The Court of Appeals first held the agreement, as amended, was substantively unfair. Id. at 834-35. The court then held the agreement, as amended, was procedurally unfair. Id. at 835. The Court of Appeals reasoned that Gloria did not have the benefit of independent counsel, that her bargaining position was grossly imbalanced, and that “at no time did [she] have full knowledge of her legal rights.” Id. Moreover, the court observed that because Gloria and Gehring believed the side letter dictated the subsequent *902amendment and because the side letter was entered into within 24 hours of the wedding, the subsequent amendment did not remedy the agreement’s procedural unfairness. Id. at 837.
¶12 We granted review. In re Marriage of Bernard, 163 Wn.2d 1011, 180 P.3d 1290 (2008).
ANALYSIS
¶13 To determine the enforceability of a prenuptial agreement, this court undertakes a two-prong analysis. In re Marriage of Matson, 107 Wn.2d 479, 482-83, 730 P.2d 668 (1986); see also In re Estate of Crawford, 107 Wn.2d 493, 730 P.2d 675 (1986); In re Marriage of Hadley, 88 Wn.2d 649, 565 P.2d 790 (1977); Friedlander v. Friedlander, 80 Wn.2d 293, 494 P.2d 208 (1972); Hamlin v. Merlino, 44 Wn.2d 851, 272 P.2d 125 (1954). The burden of proof lies with the spouse seeking enforcement. Friedlander, 80 Wn.2d at 300.
¶14 Under the first prong, the court determines whether the agreement is substantively fair, specifically whether it makes reasonable provision for the spouse not seeking to enforce it. Matson, 107 Wn.2d at 482. If the agreement makes a fair and reasonable provision for the spouse not seeking its enforcement, the analysis ends; the agreement is enforceable. This is entirely a question of law unless there are factual disputes that must be resolved in order for a court to interpret the meaning of the contract. In re Marriage of Foran, 67 Wn. App. 242, 251 n.7, 834 P.2d 1081 (1992).
¶15 If, however, the agreement is substantively unfair to the spouse not seeking enforcement, the court proceeds to the second prong. Under the second prong, the court determines whether the agreement is procedurally fair by asking two questions: (1) whether the spouses made a full disclosure of the amount, character, and value of the property involved and (2) whether the agreement was freely entered into on independent advice from counsel with full knowl*903edge by both spouses of their rights. Matson, 107 Wn.2d at 483. If the court determines the second prong is satisfied, then an otherwise unfair distribution of property is valid and binding. Id. at 482.
¶16 Analysis under this second prong involves mixed issues of policy and fact, and accordingly review is de novo but undertaken in light of the trial court’s resolution of the facts. See Foran, 67 Wn. App. at 251. On appeal, a trial court’s findings of fact will be upheld if supported by substantial evidence. Sunnyside Valley Irrigation Dist. v. Dickie, 149 Wn.2d 873, 879, 73 P.3d 369 (2003). “Substantial evidence is evidence sufficient to persuade a fair-minded person of the truth of the declared premise.” In re Marriage of Hall, 103 Wn.2d 236, 246, 692 P.2d 175 (1984).
¶17 We note as an initial matter that both parties request this court reconsider the above two-prong analysis, which was expressly set out in Matson and has characterized our analysis for over 50 years. See Hamlin, 44 Wn.2d 851. Gloria argues that this court should undertake an approach that requires both substantive and procedural fairness; that is, she argues that a substantively unfair agreement should not be saved by procedural fairness. On the other hand, Thomas argues the substantive fairness prong should be abandoned altogether because RCW 26.09.080 already directs courts to make a “just and equitable” distribution of property. We find it unnecessary to entertain these arguments because the prenuptial agreement at issue is both substantively and procedurally unfair, and the application of a different analysis would not alter the outcome here.
The Agreement
¶18 Turning to the agreement at issue, we apply the two-prong analysis to the prenuptial agreement as signed on the eve of marriage and subsequently amended 14 *904months later.5 Thomas concedes the prenuptial agreement as originally executed on the eve of marriage was substantively and procedurally unfair; therefore, we must determine whether the later amendment cured the substantive or procedural deficiencies.
¶19 Under the first prong of our analysis, the agreement is enforceable if it is substantively fair. Here, the trial court concluded the agreement as amended was substantively unfair to Gloria. The Court of Appeals affirmed, reasoning that the amended agreement severely restricted the creation of community property, eliminating community property rights in the short term while permitting Thomas to enrich his separate property at the expense of the community. Bernard, 137 Wn. App. at 834. The Court of Appeals observed that the amended agreement provided nothing for Gloria from Thomas’s separate property, nor reimbursed her for her contributions to Thomas’s separate property, nor permitted maintenance, and it precluded any inheritance. Id. at 834-35.
¶20 Thomas argues that because this was a short-term marriage there was no time to accumulate community property. He urges us to alter our analysis and evaluate substantive fairness at the time of enforcement, as opposed to at the time of execution, of an agreement. We refuse. To do so would change the test from one of fairness to fortuity. We adhere to the settled rule that “[t]he validity of prenuptial agreements in this state is based on the circumstances surrounding the execution of the agreement.” In re Marriage of Zier, 136 Wn. App. 40, 47, 147 P.3d 624 (2006) (citing Matson, 107 Wn.2d at 484).
¶21 Moreover, Thomas’s substantial labor in managing his separate assets produced revenue that is considered community property. See Hamlin, 44 Wn.2d at 858; see also 19 Kenneth W. Weber, Washington Practice: Family and *905Community Property Law § 11.14, at 161-62 (1997). Thus, the premise of Thomas’s argument is incorrect; community property accumulated during the marriage.
¶22 To be sure, "[t]here is nothing unfair about two well-educated working professionals agreeing to preserve the fruits of their labor for their individual benefit.” In re Marriage of DewBerry, 115 Wn. App. 351, 365, 62 P.3d 525 (2003). However, an agreement disproportionate to the respective means of each spouse, which also limits the accumulation of one spouse’s separate property while precluding any claim to the other spouse’s separate property, is substantively unfair. See Matson, 107 Wn.2d at 486; Friedlander, 80 Wn.2d at 301.
¶23 Here, the community property consisted of half of Gloria’s salary, which was controlled by Thomas, and in effect $100,000 of Thomas’s earnings per year. In addition, the prenuptial agreement limited Gloria’s inheritance rights, prevented Gloria from seeking spousal maintenance, prevented Gloria from using community property to assist her children, and sheltered Thomas from liability for any debts incurred by Gloria. CP at 1201-19. The prenuptial agreement as amended remedied some of these problems, but overall made provisions for Gloria disproportionate to the means of Thomas, and limited Gloria’s ability to accumulate her separate property while precluding her common law or statutory claims on Thomas’s property. CP at 1248-51. The agreement as amended is substantively unfair. It can be enforced only if it was executed fairly, the second prong of our analysis.
¶24 Under the second prong of our analysis, we ask whether the spouses fully disclosed the amount, character, and value of the property involved and whether the agreement was entered into voluntarily and intelligently. The trial court found Gloria had full knowledge of the amount, character, and value of Thomas’s assets, and Gloria does not dispute this finding. However, the trial court found that, given the timing of Gloria’s receipt of the working agreement draft in relation to the wedding and her *906discussions with her attorney, the agreement was not entered into voluntarily or intelligently. The court further found that the subsequent side letter and amendment did not cure this defect, given the limited scope of negotiations.
¶25 Because the trial court made findings of fact about the agreement’s lack of procedural fairness, we will uphold its findings if they are supported by substantial evidence. Dickie, 149 Wn.2d at 879. Here, substantial evidence supports the trial court’s findings of fact regarding procedural unfairness. There was not enough time for Gloria or her attorney to adequately review the prenuptial agreement as evidenced by the late date at which a working draft was provided and the several distractions present for Gloria in the few days before the wedding. The evidence supports the trial court’s finding that Gloria did not sign the July 7 prenuptial agreement “after receiving independent advice and with full knowledge of its legal consequences.” CP at 1816.
¶26 The trial court then considered whether the amendment to the agreement executed by Gloria and Thomas, contemplated by the July 8 “side letter,” cured the deficiencies of the July 7 agreement. The trial court found that the scope of negotiation was so limited that the amendment did not cure the defects of the agreement. Substantial evidence supports this conclusion, as demonstrated by the testimony of Gloria and Gehring, who both understood that the terms of the amendment were limited to the five areas of concern set forth in Gehring’s July 7 letter to Gloria. And the wording of the side letter is additional evidence that any amendment was limited to the matters set forth in the “side letter,” CP at 1256,6 supporting the trial court’s finding that the terms of the side letter limited renegotiation. CP at 1816 (Finding of Fact 27).
*907¶27 The trial court observed that the side letter did not expressly limit the terms of the amendment to only the five areas of concern noted by Gehring and that the agreement as amended ultimately contained a matter outside the terms of the “side letter.”7 Id. Additionally, the deadline for renegotiation was abandoned. Id. But these observations do not negate the substantial evidence upon which the trial court based its finding regarding the limits of the amendment. Especially considering the trial court’s ability to judge the weight and credibility of testimony, including Gloria’s and her attorney’s testimony that they understood the negotiations were limited, a fair-minded person would be persuaded that the side letter did not give Gloria a right to amend the prenuptial agreement beyond the few matters specified in the “side letter.” The trial court’s findings of fact in this regard are amply supported, and we will not disturb them on review. See Dickie, 149 Wn.2d at 879-80. We hold the agreement, as amended, was procedurally unfair.8
¶28 Because the prenuptial agreement was both substantively and procedurally unfair, it is unenforceable. We affirm the lower court’s invalidation of the agreement.
Attorney Fees
¶29 The trial court awarded Gloria attorney fees and costs pursuant to RCW 26.09.140. In addition, the trial court awarded Gloria fees in advance of this appeal pursuant to Stringfellow v. Stringfellow, 53 Wn.2d 359, 333 P.2d 936 (1959).
*908¶30 In Thomas’s second amended notice of appeal, he appeals both fee awards. However, he provides no supporting argument in his initial brief to the Court of Appeals or in his supplemental brief to this court. Instead, in his reply brief, Thomas argues that the prenuptial agreement, if valid, precludes an award of attorney fees and costs outside the context of arbitration. Gloria, on the other hand, consistently asked the Court of Appeals and this court to uphold both awards under RCW 26.09.140 and RAP 18.1(c).
¶31 “This court does not consider issues raised for the first time in a reply brief.” In re Marriage of Sacco, 114 Wn.2d 1, 5, 784 P.2d 1266 (1990). We affirm the trial court’s award of attorney fees and costs to Gloria and confirm the advance award of fees on appeal.
CONCLUSION
¶32 We hold the prenuptial agreement, as amended, was substantively and procedurally unfair. We affirm the Court of Appeals. In addition, we affirm Gloria’s award of attorney fees and costs, both at trial and on appeal.
Alexander, C.J., and C. Johnson, Madsen, Chambers, and Owens, JJ., concur.For ease of reference this opinion will refer to the parties by first name.
Gehring testified regarding the postnuptial agreement: “My job was [to] tell her don’t sign the [prenuptial] agreement. She signed it. Now we’re going to fix it. Well, okay. The agreement was that the — the agreement she made, we were going to limit it to certain items.”
Gloria testified regarding the postnuptial agreement: “[w]hat [Gehring] told me is . . . these are the only points that we’re able to amend, and I’m trying to do the best I can to have this wording changed or whatever on these five points . . . .”
The issue of whether the trial court should have analyzed the arbitration clause prior to determining the enforceability of the entire prenuptial agreement is not raised in this appeal. Thomas concedes the enforceability of the arbitration clause is dependent on the enforceability of the prenuptial agreement as a whole. *901See In re Marriage of Bernard, 137 Wn. App. 827, 833, 155 P.3d 171 (2007) (observing, “[n]o court has yet determined the effect of Pinkis [v. Network Cinema Corp., 9 Wn. App. 337, 512 P.2d 751 (1973)] in the context of a prenuptial agreement”).
That this case involves a prenuptial agreement, amended postnuptially, does not alter our analysis. See Hadley, 88 Wn.2d at 654 (analyzing three postnuptial agreements under the established two-prong approach).
The letter stated in pertinent part, “we and our attorneys will use their best efforts to negotiate in good faith and execute an amendment to the Agreement covering the following matters . . .” and then went on to discuss the five areas outlined in Gehring’s letter. CP at 1256. It did not reference any other substantive changes to the prenuptial agreement.
The amendment included a provision not contained in the “side letter” that further isolated Thomas’s earnings from the marital community. Br. of Resp’t at 21.
The Court of Appeals appeared to rest at least some of its determination that there was procedural unfairness on a belief that Gloria’s counsel was inadequate. Bernard, 137 Wn. App. at 836. Gloria did not make such an argument before this court or any court below. A discussion of counsel’s adequacy is unnecessary to the resolution of this case because the trial court’s findings are supported by substantial evidence without resort to consideration of the adequacy of counsel. We decline to entertain that question here.
