When you think assets are being hidden
The suspicion is usually right in outline and wrong in detail. Money is far more often deferred, understated or parked than it is stuffed in a safe. This page is about the patterns that actually occur, how each one is traced, what the professionals cost, and what happens to someone who is caught — which in one California case was the loss of an entire lottery prize.
Reading your spouse’s email, guessing their password, or putting monitoring software on their phone can be a federal crime under the Wiretap Act and the Stored Communications Act. It can also get the evidence thrown out and hand the other side a weapon. There is a genuine gray area around shared computers and shared accounts, and it is a question for a lawyer in your state, not for the internet. The legal routes below get you the same information without any of that risk.
How Assets Actually Get Hidden
There is a limited set of moves people actually make, and most of them leave a trail precisely because they have to interact with a bank, an employer, or the IRS to work.
Delaying income or reporting a sudden business downturn around the time of filing is one of the most common patterns.
Reported consistently, not settled
A spouse who controls the timing of a bonus, commission, or business distribution can ask an employer or their own company to delay payment until after the divorce is final, or a business owner can suddenly show reduced revenue, add a ‘consultant’ who is a friend or family member, or hire phantom employees, all of which reduce reported income and business value during the case while the underlying cash flow does not actually change.

Cryptocurrency is traced by following the money before following the blockchain, then subpoenaing the exchange.
Reported consistently, not settled
Investigators typically start with bank and credit card statements to find where dollars converted into crypto, then subpoena exchanges such as Coinbase or Kraken directly for know-your-customer records, deposit and withdrawal addresses, and login history, before doing on-chain path analysis across wallets. Beginning in the 2025-2026 tax years, expanded Form 1099-DA broker reporting adds a documented paper trail of crypto proceeds and basis, on top of the existing digital-asset question on Form 1040.

American Bar Association Family Law Section commentary
Neither is untraceable. Cash businesses get exposed through lifestyle analysis, comparing reported income to actual spending, and crypto gets exposed through exchange subpoenas, on-chain tracing, and the 1099-DA and digital-asset reporting now built into the tax system.
What to actually do
- Watch for a business that reports a sudden and unexplained downturn once a divorce is filed, especially if it coincides with a new ‘consultant’ or additional payroll.
- Overpaying estimated taxes intentionally, to generate a large refund that lands after the divorce is final, is a documented pattern; compare estimated payments to actual tax liability across years for anomalies.
- Custodial accounts opened in a child’s name (UTMA or UGMA accounts) can be used to park marital funds outside the marital estate; ask for account statements and the source of every deposit.
- Whole life insurance cash value, HSA balances, unvested RSUs and stock options, frequent flyer miles, points, season tickets, and club memberships are all real economic value that gets routinely left off informal asset lists; ask specifically about each one.
- A lifestyle analysis, comparing what a household actually spent (mortgage, private school, vacations, cars) against what was reported as income, is the standard method for proving unreported cash income.
- A transfer to a family member shortly before filing is not automatically illegal, but if it was made to put an asset out of the other spouse’s reach, it can be challenged as a fraudulent transfer; the timing and the recipient’s relationship to the transferring spouse are what matters.
- Patterns described here are common investigative findings, not a guarantee of what happened in any specific case. Do not accuse a spouse of hiding assets based on a pattern alone; get the documents first.
What Happens to Someone Who Hides Assets
Courts treat concealment of marital assets as a serious breach of a fiduciary duty spouses owe each other, and the penalties can be severe, including losing the entire asset that was hidden.
A California wife who hid a $1.3 million lottery win lost the entire prize to her husband.
In In re Marriage of Rossi, the California Court of Appeal upheld an order awarding 100 percent of a $1,336,000 lottery jackpot to the husband, after the wife won the lottery, did not disclose it, filed for divorce eleven days later without mentioning it, and later lied about it under oath before the truth came out. The court applied Family Code section 1101(h), the fiduciary-duty breach remedy, which allows an award of 100 percent of an undisclosed or transferred asset when the concealment rises to the level of fraud, malice, or oppression under Civil Code section 3294.
Remedies for the breach of the fiduciary duty by one spouse when the breach falls within the ambit of Section 3294 of the Civil Code shall include…an award to the other spouse of 100 percent…of any asset undisclosed or transferred in breach of the fiduciary duty.
California lets a defrauded spouse reopen a final divorce judgment, but only within one year of discovering the fraud.
Family Code section 2122 allows a judgment to be set aside for actual fraud that kept the other party from fully participating, or for perjury in the disclosure declarations or income and expense statement, but both grounds carry a strict one-year deadline running from when the complaining party discovered, or should have discovered, the fraud or perjury.
An action or motion based on fraud shall be brought within one year after the date on which the complaining party either did discover, or should have discovered, the fraud.
California’s disclosure statute independently requires sanctions and can force a judgment to be set aside for noncompliance, separate from the fraud-specific Rossi remedy.
Beyond the Rossi 100-percent remedy, Family Code section 2107 requires monetary sanctions for a failure to comply with disclosure obligations and mandates that a judgment be set aside if it was entered while disclosure requirements were unmet.
In California and states with similar rules, a final judgment can be reopened for fraud or perjury in the disclosures, but only within a limited window (one year in California) after the fraud was discovered or should have been discovered. Waiting matters.
What to actually do
- If you discover a hidden asset after judgment, act immediately. The one-year clock in states like California runs from when you discovered or reasonably should have discovered the concealment, not from the date of judgment.
- Document the date you discovered the concealment and how, since that date determines whether you are still inside the window to reopen the case.
- The Rossi outcome, losing 100 percent of the asset, is an extraordinary remedy tied to conduct the court found to be fraud, malice, or oppression, not a guaranteed outcome for every disclosure mistake. State remedies for concealment vary; confirm your own state’s rule.
What Not to Do
The instinct to read a spouse’s email, install spyware, or dig through a shared phone is understandable and can be a federal crime. It can also get real evidence thrown out of your own case.
Intercepting a spouse’s communications, such as through spyware, can violate the federal Wiretap Act, a felony with up to five years in prison.
The Wiretap Act makes it a crime to intentionally intercept, or use a device to intercept, any wire, oral, or electronic communication, or to disclose or use the contents of a communication known to have been illegally intercepted. A violation carries a fine, or imprisonment of up to five years, or both.
Whoever violates subsection (1) of this section shall be fined under this title or imprisoned not more than five years, or both.
Reading a spouse’s stored email or messages without authorization can violate the federal Stored Communications Act.
The Stored Communications Act makes it a crime to intentionally access, without authorization, a facility through which an electronic communication service is provided, or to exceed authorized access, and thereby obtain, alter, or prevent authorized access to a stored communication. Penalties scale with intent and repetition, up to five years for a first offense done for commercial advantage or malicious purposes, or up to one year for other first offenses.
Whoever intentionally accesses without authorization a facility through which an electronic communication service is provided…and thereby obtains, alters, or prevents authorized access to a wire or electronic communication while it is in electronic storage in such system shall be punished.
This is a genuine gray area, not a green light. Courts have gone different ways depending on whether the account was truly shared with mutual, ongoing authorization versus one spouse’s separate account that happened to be accessible. Whether a specific access was ‘authorized’ under these statutes is a fact-specific legal question. This is not something to guess about; ask a lawyer in your state before accessing an account, device, or communication that is not clearly and entirely your own, especially if a password was ever changed, an account was ever separated, or the other spouse would say it was theirs.
What to actually do
- Do not install spyware, keyloggers, or tracking apps on a spouse’s device or phone, even if you own the device or pay the phone bill.
- Do not log into a spouse’s separate email or social media account using a password you found or guessed, even if you were once given it for another reason.
- If evidence was already obtained this way before you knew the risk, tell your lawyer exactly how you got it before trying to use it. Illegally obtained evidence can be excluded from your own case, and disclosing it to your attorney is how you find out whether that risk applies.
- This is squarely a question for a lawyer in your state before you act, not after. The consequences described here are federal criminal exposure, not a civil inconvenience, and state laws can add further restrictions or, occasionally, different exceptions.
