After the trial court partially granted Quyen Chau Nguyen’s Family Code section 21221 motion to set aside a judgment entered pursuant to a marital settlement agreement, Can Quang Nguyen filed a notice of appeal from the resulting order.2 He argues the court erred in finding Quyen’s motion was timely because the undisputed evidence demonstrated Quyen knew or should have known about Can’s failure to comply with statutory disclosure requirements, on which she based her motion, at the time she signed the martial settlement agreement roughly two years prior to filing her motion. In addition, he contends the court abused its discretion in concluding Quyen was entitled to an equitable distribution of the undisclosed retirement accounts in his name. Although we find the order from which Can appeals is not appealable, we exercise our discretion to treat the appeal as a petition for writ of mandate. On the merits, we conclude Quyen’s motion was untimely because, as a matter of law, she should have discovered Can’s failure to disclose the disputed retirement accounts at the time the parties signed the martial settlement agreement. With the set-aside motion being filed outside the maximum one-year limitations period for filing such a motion pursuant to section 2122, the motion should have been denied in full. Accordingly, we

by first name. No disrespect is intended.

2 issue a peremptory writ of mandate directing the trial court to vacate the challenged order and enter a new order denying the set-aside motion in its entirety. FACTS I. THE MARITAL SETTLEMENT AGREEMENT AND JUDGMENT

After more than 20 years of marriage, and after their children reached the age of majority, Can filed a marital dissolution petition in late January 2020. About one week later, the parties signed and had notarized a marital settlement agreement (MSA). The MSA conveyed the parties’ intent “to resolve all issues remaining in their case” and “waive any inequality [in division of their assets and debts] in the interest of reaching a full and final resolution of their matter.” Consistent with that intent, it specified it “contain[ed] the entire agreement of the parties on [the] matter,” no other agreement or promise made on or before its effective date would be binding unless in writing and signed by both parties, and subsequent modifications would need to be in writing and signed by both parties. In addition to providing for a $1,000 monthly spousal support payment from Can to Quyen, the MSA specified the way community property would be divided. Can was to take as his sole and separate property: the marital residence, along with any encumbrances and liabilities associated with it; “any and all retirement plans, 401K plans, pension benefits or other accrued benefits through [his] current or former employer(s)”; bank accounts in his name alone; and cash, household goods and furniture, and personal effects in his possession. Quyen was to take as her sole and separate property: “any and all retirement plans, 401K plans, pension benefits or other accrued benefits through [her] current or former employer(s)”; bank accounts

3 in her name alone; and cash, household goods and furniture, and personal effects in her possession. The MSA also contained various waiver and disclosure related provisions. Under a “Retirement Plan” heading, the “parties waive[d] any and all right, title and interest each may have in any retirement plans and benefits in the name of their spouse and any plans and/or benefits that exist are confirmed to each party as their separate property.” A financial disclosures section stated: (1) the parties complied with section 2104 “regarding the exchange of preliminary declarations of disclosure”; (2) the parties each “understand[] that noncompliance with those obligations will result in the court setting aside the judgment”; (3) the parties complied with section 2102 “and have fully augmented the preliminary declaration of disclosure”; (4) the parties waived the filing of a final declaration of disclosure; and (5) such waiver did not “limit the legal disclosure obligations of the parties but rather [was] a statement under penalty of perjury that those obligations [were] fulfilled.” And, in a section concerning legal counsel, the parties acknowledged they each “voluntarily refused to consult with any attorney, . . . read and underst[ood] the contents and legal effect [of the MSA,] . . . entered into it and signed it freely and voluntarily, and . . . waive[d] any right to rescind or set aside [the MSA] except upon a finding that there has been an actual misrepresentation, knowingly made with intent to defraud.” Pursuant to a request by Can, and consistent with a provision in the MSA, the trial court entered default against Quyen in June 2020 due to her lack of response to the dissolution petition. A few days later, the court entered judgment, dissolving the marriage and dividing property as specified

4 in the MSA, which it attached to the judgment. That same day, the court sent the parties a notice of entry of judgment. II. THE SET-ASIDE MOTION

In February 2022, Quyen filed a motion to set aside the default and the judgment pursuant to section 2122, or alternatively for a postjudgment division of property and enforcement of an equalization payment. In an accompanying declaration, she stated Can represented during their negotiation of the MSA that he had disclosed all martial assets and debts to her and “that he would buy [her] interest in the family residence . . . for One Hundred and Fifty Thousand Dollars.” He did not include the agreed upon equalization payment in the MSA, he never made the equalization payment, and he failed to disclose two of his retirement accounts (the Aerospace retirement accounts).3 Quyen noted Can provided her a list of his financial accounts, including the Aerospace retirement accounts, when they contemplated divorce in 2014. She forgot about the information until after they divorced in 2020 and subsequently located it in her old files. Attached to the motion was a declaration of disclosure, signed by Can and dated February 2020, which only listed one asset—the marital residence. Can opposed the motion. In a declaration, he stated he and Quyen discussed divorce on more than one occasion before he filed for divorce in 2020. During those discussions, they listed all their assets and detailed
