The short answer
Hidden assets usually show up as sudden drops in income, new debts to friends or family, cash withdrawals, business "losses" that appear right before separation, and a reluctance to share documents. Full financial disclosure is mandatory in Canada and the US, and an agreement signed without it can be set aside. Start with the paper trail, then escalate.
Start with the reassuring fact: most people going through separation are not hiding money. They are disorganised, frightened and sometimes petty, but the accounts are mostly what they appear to be. Hidden assets are the exception. The problem is that the exception is expensive, and the people who do it tend to follow the same playbook. Once you know the playbook, it is hard to miss.
The disclosure obligation
In every Canadian province and every US state, spouses owe each other full and honest financial disclosure when they separate. In Ontario the obligation is set out in the Family Law Rules and enforced through Form 13 or 13.1 financial statements. In BC, the Family Law Act makes disclosure a condition of a valid agreement. In the US, most states require sworn financial affidavits or declarations of disclosure; California's preliminary and final declarations are among the strictest.
The consequence of hiding assets is severe. A separation agreement signed without full disclosure can be set aside years later. Courts have awarded the innocent spouse the entire hidden asset, ordered costs against the concealing spouse, and in criminal cases prosecuted perjury on sworn financial statements. The law is on your side. You just have to use it.
The warning signs
Income that suddenly falls
A business owner whose revenue drops 40 percent in the year before separation. A commissioned salesperson whose commissions dry up. Bonuses that are "deferred" this year. When income declines conveniently, ask for three prior years of tax returns and the current year's pay stubs, and compare.
New debts
"I owe my brother $30,000." Loans to family and friends that appear during separation are a classic way to reduce net worth on paper. Ask for the loan agreement, the bank record of the funds arriving, and the repayment history. A real loan has a paper trail.
Cash
Regular ATM withdrawals, cash-heavy businesses, safety deposit boxes you have never seen opened. Cash is the oldest hiding place. Bank statements show withdrawals even when they don't show where the cash went.
Transfers to third parties
Money moving to a parent, a sibling, a new partner or a business associate "for safekeeping" or as a "gift." Anything transferred out of the ordinary course in the two years before separation deserves a question, and in most jurisdictions courts can reverse transfers made to defeat a spouse's claim.
Business manoeuvres
Delayed invoicing so revenue lands after the valuation date. Prepaid expenses. New "consultants" who happen to be friends. Excess inventory or equipment purchases. A corporation that suddenly needs to retain all its earnings. If your spouse owns a business, read how a business is divided at separation.
Digital assets
Cryptocurrency, online brokerage accounts in a different country, PayPal or payment app balances, gaming or reselling income. These are easy to overlook and easy to omit. Ask directly and in writing.
Behaviour
Delay, partial disclosure, missing pages, statements that always seem to start the month after something interesting happened. The pattern of how someone discloses is often more telling than what they disclose.
What you can do, in order
1. Secure what you already have access to
Before you announce any suspicion, copy everything you can lawfully see: joint account statements, tax returns, the family computer's tax software, mail addressed to both of you, statements in the shared filing cabinet. Do not log into accounts that are not yours or in your name. Unauthorised access can be a criminal offence and it can taint the evidence.
2. Ask in writing, specifically
General requests get general answers. Ask for named things: "all statements for the TD line of credit ending 4471 from January 2023 to date," "the corporate financial statements and general ledger for 2023 and 2024," "any cryptocurrency wallet or exchange account." FairWell's Financial Disclosure Package includes a jurisdiction-specific checklist so nothing is missed.
3. Use the formal process
Sworn financial statements, requests to admit, and in litigation, questioning or deposition under oath. Lying under oath is a different category of risk than lying to a spouse, and most people know it.
4. Compel third-party records
Courts can order banks, employers, accountants and business partners to produce records. In Canada this is usually a motion for disclosure; in the US, subpoenas. Lawyers do this routinely.
5. Bring in a forensic accountant
For business interests, complex investments or a lifestyle that doesn't match declared income, a forensic accountant traces money, reconstructs income and values businesses. Fees run from a few thousand dollars for a targeted review to much more for a full investigation. Weigh the cost against what you believe is missing. In many cases a lawyer's letter announcing that a forensic accountant has been retained produces sudden disclosure.
Don't become the problem
Two cautions. First, do not hide anything yourself, including moving money "to be safe." It is easy to prove and it destroys your credibility on every other issue. If you need to protect funds from being drained, a lawyer can seek a preservation order or you can agree a joint freeze. Second, be honest about the size of the issue. Spending $20,000 on a forensic investigation to find $15,000 is a win for nobody but the professionals.
If you signed without knowing
An agreement based on incomplete or false disclosure can be reopened. In Ontario, section 56(4) of the Family Law Act allows a court to set aside an agreement where a party failed to disclose significant assets or debts. Similar provisions exist across Canada and in US states. Time matters, so act as soon as you learn of it, and gather the proof before you raise it.
Common questions
Can I look at my spouse's phone or email for evidence?
Do not access accounts or devices that are not yours without permission. It may be illegal, and evidence obtained that way can be excluded and used against you. Use the formal disclosure process instead.
How far back can disclosure go?
Typically three years of income records as a starting point, with older records available on request where relevant, for example to trace a pre-marriage asset. Transfers made to defeat a claim can be examined regardless of date.
What does a forensic accountant cost?
It varies widely with scope. A focused review of a small business might be a few thousand dollars; a full investigation of complex holdings can be far more. Get a scoped quote and set a budget cap.
Is cryptocurrency really traceable?
Exchange accounts are, because exchanges keep records that can be compelled. Self-custody wallets are harder, but the money had to come from somewhere, and that on-ramp is usually visible in bank records.
