Short answer: Ontario’s Family Law Act divides the financial product of a marriage through equalization of net family property, and the entire machine runs on one input: honest, sworn disclosure from both spouses. Ontario’s Family Law Rules require sworn financial statements in property and support claims, and the duty to disclose is continuing, not a one-time form. When one spouse’s sworn numbers do not match the life you watched them live, that gap is not a feeling to swallow. It is a fact pattern that can be investigated lawfully, documented credibly, and put in front of a court that has statutory tools to deal with it.
Equalization runs on disclosure
The equalization scheme is arithmetic: each spouse calculates the growth in their net worth over the marriage, and the spouse who gained more pays the other half the difference. Every hidden asset corrupts the arithmetic directly, which is why family courts treat disclosure as the foundation of the process rather than a formality. It is also why hiding assets is a strategy with a long tail: the sworn financial statement is an anchor document, and a spouse who signs a false one has converted a negotiation problem into an evidence problem that follows them for years.
Suspicion, to be clear, is not proof, and most suspicion in a divorce is just grief with a spreadsheet. The point of investigation is to resolve the question honestly in either direction before it drives the litigation: confirm the picture is what it claims to be, or document the specific reasons it is not.
Where assets actually hide
The patterns repeat. Income suppressed through a cash business or through a corporation that suddenly pays its owner less while retaining more. Bonuses, commissions and receivables deferred until after separation. A new corporation or holding company formed mid-conflict, sometimes with a relative or new partner as the visible face. Transfers to family members, repayment of convenient "loans" nobody documented when times were good. Property or vehicles registered to others but used exclusively by the spouse. Overpaid taxes parked with the CRA for a post-divorce refund. Cryptocurrency moved to self-custody, invisible to a casual look but rarely as invisible as its owner believes, because purchases, transfers and lifestyle still leave records.
None of these is exotic. They are visible in the mismatch between sworn numbers and observable facts: the declared income that cannot fund the observed lifestyle, the business that is busy on-site while reporting decline, the vehicle that lives at the house but appears on no statement.
What is lawfully searchable, and what is not
A substantial layer of the truth sits in public registries that anyone, including an investigator working for your lawyer, can lawfully search: land registry records for real property and mortgages, corporate registries for directorships and new entities, personal property security registrations that show what has been financed and by whom, court files for lawsuits and judgments, and bankruptcy records. Layered on that is lawful observation: documenting from public vantage points that a supposedly dormant business runs daily jobs, or that a disclaimed vehicle is in daily use, and open-source research that ties visible spending and ventures to a timeline. We cover the mechanics of the searchable layer in our guide to asset searches in Ontario.
Be equally clear about the other side of the line, because it protects you. Bank balances, account statements and detailed banking activity are not obtainable by any investigator, for anyone, without the account holder’s consent or a court process. In a family proceeding that is not a dead end; it is the division of labour. The investigation documents the grounds for disbelief, and your lawyer uses those grounds to drive targeted disclosure orders, questioning and, where justified, document production that reaches what no investigator lawfully can. Anyone who offers to get bank records directly is offering something unlawful that would poison the case it was meant to help, a line we draw in the same place in every practice area.
What non-disclosure costs the spouse who tries it
Ontario’s Family Law Act deals directly with the end-game. Under section 56(4), a court may set aside a domestic contract, a separation agreement included, where a party failed to disclose significant assets, debts or liabilities that existed when the contract was made. The power is discretionary rather than automatic, and courts weigh significance against the whole picture, but the practical meaning for a hiding spouse is stark: the settlement they extracted through concealment is never final. Discovery of the hidden asset years later can reopen what they thought they had closed, this time with their credibility already spent. For the spouse on the other side, the same section is the reason documentation matters even after settlement: a record built once keeps its value.
The working team: lawyer, investigator, and sometimes an accountant
These files run best as a triangle. Your family lawyer owns strategy, disclosure motions and the court process. The investigator supplies what the registries, the field and open sources lawfully yield: the documented mismatches that justify the motions. Where a business’s books are themselves the battlefield, a forensic accountant reads what disclosure produces. The sequence matters: documented grounds first, then targeted legal process, then expert analysis. Started in that order, the file gets more affordable and more credible at every step, which is the standard we work to in corporate and personal due diligence and in every family file counsel brings us.
Not legal advice
This article is general information about Ontario family property law, not legal advice, and equalization has exceptions and deadlines this overview does not cover. Get advice from a family lawyer early, and treat any investigator promising direct access to bank records as the red flag it is.
Frequently asked questions
How do I find hidden assets in a divorce?
Through layers, in order: your own records and knowledge of the marriage, lawful searches of public registries (land, corporate, personal property security, court and bankruptcy records), lawful observation and open-source research documenting the mismatch between sworn disclosure and observable life, and then court-ordered disclosure driven by your lawyer using that documentation. Each layer justifies and sharpens the next.
Can a private investigator access my spouse’s bank accounts?
No. Bank records are not lawfully obtainable by any investigator without the account holder’s consent or a court process, full stop. What an investigator lawfully provides is the documented grounds, registry findings, observed business activity, lifestyle-versus-declared-income evidence, that let your lawyer obtain targeted disclosure and production orders which do reach the accounts.
What happens if my ex hid assets and we already signed an agreement?
Ontario’s Family Law Act, s. 56(4), lets a court set aside a domestic contract, including a separation agreement, where a party failed to disclose significant assets or debts that existed when it was made. The remedy is discretionary and fact-dependent, so speak to a family lawyer promptly once you have specifics, and preserve every document showing what was hidden and when you learned of it.
Can cryptocurrency be hidden in a divorce?
It can be moved out of easy view, but rarely out of reach. Purchases leave banking and exchange records that court-ordered disclosure reaches, transfers leave permanent public blockchain records, and spending leaves lifestyle evidence. Open-source research can document the existence and timeline of crypto activity, and disclosure obligations apply to crypto exactly as they do to any other asset.
