[CA] Can a divorce settlement be reopened if a spouse hid a business’s true value before selling it?

I understand how frustrating this situation must be for you, especially after all the hard work you put into your business. Did you have any legal representation during your divorce proceedings when you signed the agreement regarding the house and business?

Have you gathered any documentation or evidence that supports your claim of duress when you signed the agreement?

Is there anything else the attorney should know before I connect you? Rest assured they'll be able to help with your divorce agreement.

Hello, my name is Daniel, and I've been a licensed attorney for over 22 years. I'm sorry you're dealing with this situation, and I'll do everything I can to help. You mentioned signing an agreement under duress during your divorce, and now your ex has sold the business for a significant amount. Could you tell me more about any steps you've considered or taken so far regarding this?

Could you let me know which state or jurisdiction your divorce took place in? This will help me understand the legal framework that applies to your situation.

Thank you for sharing that. It sounds like you've made significant contributions to both your family and the business. Could you tell me if there were any formal agreements or contracts regarding the business or your financial contributions during your marriage?

Thanks, I appreciate you clarifying that. I'm finalizing your answer now and should have it for you shortly.

I can hear how painful and stressful this situation still feels for you, especially after a long marriage and years of contributing time, money, and effort into building the preschool.

Under general contract and family law principles, especially in California, marital settlement agreements signed during divorce are usually considered binding once the court enters judgment. However, there are limited situations where a court can set aside or modify an agreement, such as fraud, duress, or undue influence. "Duress" means you were pressured in a way that took away your real ability to freely choose, but courts typically require clear evidence, not just that the decision later felt unfair or emotionally overwhelming. This leaves you with a few possible legal paths to consider.

Your first option is to pursue a request to set aside the divorce agreement based on duress or undue influence, grounds addressed under California Family Code § 2122, which governs the time limits and grounds (including actual fraud, duress, and mistake) for setting aside a judgment. This would involve filing a motion with the family court asking the judge to reopen the judgment and review whether the agreement was truly voluntary. In practical terms, you would gather any evidence showing pressure at the time, such as messages, witnesses who were present, or proof that you were rushed, misled, or denied meaningful legal guidance. You would also need to explain your financial contributions to the business and why the agreement was fundamentally unfair. The goal of this option is to convince the court that the agreement should not have been enforced as written.

Another option may be to pursue a claim for breach of fiduciary duty related to the business sale and marital financial dealings. In California, spouses owe each other a fiduciary duty under California Family Code § 721, meaning they must act with honesty and fairness in handling marital assets, including business interests, along with disclosure obligations found in California Family Code §§ 2100 to 2113. If your ex concealed value, manipulated the timing of the sale, or failed to disclose information during the divorce process, that can sometimes create a separate legal basis for recovery even years later. The next step here would be to request records of the business sale, including closing documents, valuation reports, and tax filings, to determine how the transaction was structured and whether any disclosures were incomplete or misleading.

A third option is to seek post-judgment financial relief based on omitted or undisclosed assets, an avenue also connected to the disclosure requirements above and to relief for mistake or nondisclosure under Family Code § 2122. If the preschool's true value was not fully disclosed or was significantly understated during the divorce, the court can sometimes divide those hidden or improperly valued assets even after the judgment is final. Practically, this would involve obtaining financial documentation from the time of divorce, comparing it to the eventual $2 million sale, and identifying whether the business was misrepresented in value or structure during settlement negotiations. This option focuses less on emotional pressure and more on financial accuracy at the time the agreement was made.

Based on what you have shared, the most effective starting point is usually the post-judgment financial review focused on valuation and disclosure of the business. Courts are often more willing to revisit cases where there is a concrete financial discrepancy than to undo a settlement solely on claims of duress many years later. The biggest uncertainty here is timing and what documentation still exists from the divorce and the business sale, since those records will heavily influence whether any relief is realistic.

Please let me know if these options make sense to you. I am happy to explain anything further. It's important to me that you fully understand your choices.

Yes, you would. I think our messages may have just crossed each other. Please let me know if you received it. If it's not showing on your end, please just let me know and I will resend it. Thanks.

You can consider filing a motion to set aside the divorce agreement based on duress. This would involve gathering evidence that shows you were pressured into signing the agreement. Evidence could include any communications, witnesses, or circumstances that demonstrate you didn't have a fair choice. If the preschool's value was not accurately disclosed during the divorce, you might be able to seek relief for omitted or undisclosed assets. This would involve comparing financial documentation from the time of the divorce with the recent sale. Please let me know if you have further questions or need clarification on any of these options.
