Key Takeaways
- Spouses owe each other a fiduciary duty of full disclosure that continues after separation until each asset and debt is divided.
- Once records show that community assets were in one spouse’s control after separation and are now missing, that spouse must account for them.
- Concealing an asset can cost the concealing spouse half of it plus attorney’s fees, or all of it when the concealment amounts to fraud, oppression, or malice.
- A 2025 appellate decision upheld collecting a breach award from the breaching spouse’s retirement accounts.
Hidden-asset cases are rarely won with one dramatic document. They are won by following the money one account at a time, comparing statements, tax returns, business records, and sworn disclosures until the numbers either reconcile or they do not.
California law gives the spouse on the outside real tools, and the consequences of concealment are serious. Here is how the process works, step by step.
Step 1: Start With the Duty to Disclose
Spouses in California are fiduciaries to each other. Each owes the other the highest good faith and fair dealing, and neither may take unfair advantage of the other. (Fam. Code, § 721.) For community assets and debts, that duty includes full disclosure of their existence and equal access, on request, to the records that bear on their value and character. (Fam. Code, § 1100, subd. (e).)
The duty does not end at separation. Until each asset or debt is actually divided, each spouse must make an accurate and complete disclosure of all assets, liabilities, current earnings, accumulations, and expenses, and must update it immediately when there is a material change. A spouse must also disclose in writing any investment or business opportunity that arises after separation but results from an investment, significant business activity outside the ordinary course of business, or other income-producing opportunity during the marriage. (Fam. Code, § 2102.)
These duties are carried out through declarations of disclosure. The preliminary declaration must list every asset and debt regardless of how a spouse characterizes it and include a current income and expense declaration, and the final declaration, unless waived, adds the material facts about characterization, value, and income. (Fam. Code, §§ 2104, 2105.) When a spouse fails to comply, the court must impose money sanctions large enough to deter repetition, including attorney’s fees and costs, unless it finds the spouse acted with substantial justification or that other circumstances make sanctions unjust. (Fam. Code, § 2107, subd. (c).)
The sanctions can be substantial. In In re Marriage of Feldman, the Court of Appeal upheld $250,000 in sanctions and $140,000 in attorney’s fees against a husband who failed to disclose financial information, and held that the wife did not have to prove the nondisclosure caused her actual harm. (*In re Marriage of Feldman* (2007) 153 Cal.App.4th 1470.)
Step 2: Trace the Paper Trail
Following the money starts with records, not accusations. Bank and brokerage statements, credit card records, tax returns and schedules, loan applications, business ledgers, payroll records, and payment app histories each show part of the picture. Formal discovery and subpoenas fill the gaps the disclosures leave.
The question is whether the records reconcile. Spending that outruns reported income, unexplained transfers, new debts to friends or business associates, large cash withdrawals, tax overpayments that will come back as refunds, and transfers to accounts or wallets that never appear on a disclosure are all reasons to look harder. None of them proves concealment on its own.
When a case involves a business, complex investments, or heavy account activity, a forensic accountant can reconstruct what came in, what went out, and where it went, and test each explanation against the records. Tracing where money went is a different question from whether an asset is community or separate property, and both can matter.
Step 3: Make the Managing Spouse Explain
Hidden-asset cases often turn on who has to prove what. The spouse who controlled the money is in the best position to explain it, and once a threshold showing is made, California law puts the burden there.
In In re Marriage of Prentis-Margulis & Margulis, the Court of Appeal held that once the nonmanaging spouse makes a prima facie showing of the existence and value of community assets that were in the other spouse’s control after separation, the burden shifts to the managing spouse to prove the proper disposition or lesser value of those assets. If the managing spouse cannot, the court should charge that spouse with the assets according to the prima facie showing. (*In re Marriage of Prentis-Margulis & Margulis* (2011) 198 Cal.App.4th 1252.)
This is where the paper trail pays off. Account statements near the date of separation, tax schedules, transfer histories, and business records can make the initial showing. From there, the spouse on the outside does not have to prove exactly where every dollar went.
Step 4: Apply the Remedies
A spouse has a claim against the other for a breach of fiduciary duty that impairs the claimant’s present undivided one-half interest in the community estate, and the court can order an accounting and determine the parties’ rights. (Fam. Code, § 1101.) The remedy depends on what the evidence shows.
- Half the asset, plus fees. For an asset undisclosed or transferred in breach of the fiduciary duty, the remedies include an award of 50 percent of the asset, or an amount equal to 50 percent, plus attorney’s fees and court costs. The asset is valued at its highest value on the date of the breach, the date of its sale or disposition, or the date of the award. (Fam. Code, § 1101, subd. (g).)
- The whole asset, for fraud, oppression, or malice. When the breach falls within Civil Code section 3294, which covers oppression, fraud, and malice, the remedies include an award of 100 percent of the undisclosed or transferred asset, or an amount equal to it. (Fam. Code, § 1101, subd. (h); Civ. Code, § 3294.) Section 3294 defines fraud to include intentionally concealing a material fact to deprive another person of property or legal rights. Not every incomplete disclosure qualifies.
The best-known example is In re Marriage of Rossi. A wife won a share of a lottery jackpot worth more than $1.3 million, filed for divorce within weeks, had lottery correspondence sent to her mother’s address, and never disclosed the winnings. Her former husband learned of them after the divorce, when a letter addressed to her offering a lump-sum buyout arrived at his home. The trial court found her concealment was fraud and awarded him 100 percent of the winnings, and the Court of Appeal affirmed. (*In re Marriage of Rossi* (2001) 90 Cal.App.4th 34.)
An asset discovered after judgment is not necessarily lost. The family court keeps continuing jurisdiction over community assets and debts the judgment never adjudicated, and it divides them equally unless it finds good cause that the interests of justice require an unequal division. (Fam. Code, § 2556.)
Step 5: Collect the Award
A judgment is only as good as the ability to collect it, and collection is hardest when the breaching spouse’s remaining wealth sits in retirement plans that federal law ordinarily protects.
In In re Marriage of DeBenedetti & Ensberg, the family court found that the husband, a former Major League Baseball player, breached his fiduciary duty and awarded the wife $1,831,250 under section 1101, subdivision (g), her share of community funds that went missing under his management. To collect, the court assigned four of his ERISA-governed retirement accounts to her through separate qualified domestic relations orders. The Court of Appeal affirmed. It held that a section 1101, subdivision (g) reimbursement creates a marital property right, which brings orders enforcing it within ERISA’s exception for qualified domestic relations orders. (*In re Marriage of DeBenedetti & Ensberg* (2025) 110 Cal.App.5th 1035.)
The holding is specific to that kind of order and that kind of award. It does not make every retirement account available for every judgment, and the plan’s terms and federal requirements still have to be met.
Cryptocurrency and Form 1099-DA
Digital assets are hard to find when they are scattered across exchanges, wallets, and devices, and cryptocurrency has long appealed to a spouse who wants money that does not appear on a bank statement. A new IRS form helps, within limits.
Brokers must report gross proceeds to the IRS on Form 1099-DA for digital asset sales and exchanges they effect on or after January 1, 2025, and cost basis for certain assets acquired on or after January 1, 2026 and held at the same broker. The rules reach custodial brokers, meaning platforms that take possession of the assets being sold, including trading platforms, certain hosted wallet providers, kiosks, and certain payment processors. (IRS, Instructions for Form 1099-DA; IRS, Digital Assets.)
Decentralized and noncustodial platforms that never hold the assets are not covered, and moving crypto to a self-custody wallet does not by itself generate a Form 1099-DA. The form is a starting point for tracing, not a complete inventory. Our article on cryptocurrency and digital assets in divorce covers tracing in more detail.
If You Suspect Your Spouse Is Hiding Assets
- Gather the records you already have lawful access to, such as joint account statements, filed tax returns, and documents mailed to you. Do not access accounts or devices you are not authorized to use.
- Do not move or hide property in response. Once a divorce is filed, the automatic temporary restraining orders bar both spouses from transferring, encumbering, concealing, or disposing of property without written consent or a court order, except in the usual course of business or for the necessities of life, and they require notice of proposed extraordinary expenditures and an accounting for those made. (Fam. Code, § 2040, subd. (a)(2).) The orders bind the filing spouse at filing and the other spouse once served. (Fam. Code, § 233.) Starting January 1, 2027, they also bar letting family insurance lapse for nonpayment of premiums. See our article on new California family laws for 2027.
- Ask early for the account statements and documents behind the other spouse’s disclosures, and insist on updates when circumstances change. (Fam. Code, § 2102.)
- Bring in a forensic accountant before settlement positions harden, not after.
- If an asset surfaces after judgment, act promptly. The court can still divide it, and the section 1101 remedies may apply.
Frequently Asked Questions
What happens if a spouse hides assets in a California divorce?
The remedies include an award of 50 percent of the hidden asset plus attorney’s fees and costs, or 100 percent of it when the concealment amounts to fraud, oppression, or malice under Civil Code section 3294. (Fam. Code, § 1101, subds. (g), (h).) Disclosure failures also bring mandatory sanctions unless the spouse acted with substantial justification or sanctions would be unjust. (Fam. Code, § 2107, subd. (c).)
Can a divorce be reopened if hidden assets are found later?
Often it does not need to be. The court keeps continuing jurisdiction to divide community assets and debts the judgment never adjudicated, on a postjudgment motion. (Fam. Code, § 2556.) In In re Marriage of Rossi (2001) 90 Cal.App.4th 34, a former husband was awarded 100 percent of concealed lottery winnings after the divorce.
Who has to prove where the money went?
Once the other spouse makes a prima facie showing that community assets of a certain value were in the managing spouse’s control after separation, the managing spouse must prove what happened to them or that they were worth less. (In re Marriage of Prentis-Margulis & Margulis (2011) 198 Cal.App.4th 1252.)
Do I need a forensic accountant?
Not in every case. When one spouse controls the finances, owns a business, or spends beyond the income reported, a forensic accountant is often the most efficient way to follow the money. The cost should be weighed against what is at stake.
