Key takeaways
  • Financial disclosure documents are needed where a case involves child support, spousal support or property.
  • Sworn financial statements, case conferences and motions are tools for pressing for disclosure.
  • A court may refuse to enforce a separation agreement, or set it aside, where significant assets or debts were not disclosed.
  • Setting aside an agreement is not automatic; a court has discretion.

Many people reach separation with a sinking feeling that the numbers do not add up: income that seems lower than it should be, accounts you have never seen, or a spouse who becomes suddenly vague about money. Suspicion alone is not proof, but Ontario's process has ways to require disclosure.

This article explains the disclosure duties, the tools used to compel information, and what can happen when someone hides assets. It is general information only, and a lawyer can assess your particular facts.

What each spouse must disclose

When a case involves child support, spousal support or property, financial disclosure documents are needed. In court, each side completes a commissioned financial statement: Form 13 where only support is claimed, and Form 13.1 where property or debts are claimed. A Certificate of Financial Disclosure (Form 13A) also applies to support or property claims.

In a proceeding under the Divorce Act, the parties also have wider duties, including to give complete, accurate and current information when the Act requires it and to comply with orders. In divorce cases, the Divorce Act also requires legal advisers, unless it is clearly inappropriate, to raise reconciliation and encourage family dispute resolution, and to certify compliance in filed documents.

Signs worth documenting

If you suspect something, write down what you have noticed and why, rather than confronting your spouse. Details help a lawyer decide what to request.

Do not break into accounts, devices or email to look for evidence. How you obtain information can create its own problems, so ask a lawyer before acting.

How disclosure can be compelled

In most family cases, the steps are the Mandatory Information Program, a first appearance (in Family Court branches, except for divorce, property or arbitration award cases), a case conference, a settlement conference, and then trial scheduling and management conferences. The case conference brief is limited to 8 pages and the settlement conference brief to 12 pages.

If voluntary disclosure is not happening, a motion can be brought using Form 14 (Notice of Motion) and Form 14A (Affidavit). The specific orders a court can make about missing disclosure depend on the facts and the rules, so a lawyer can explain which requests make sense in your case.

ToolWhat it does
Financial statements (Form 13 or 13.1)Form 13 is used where only support is claimed, and Form 13.1 where property or debts are claimed; both are commissioned
Certificate of Financial Disclosure (Form 13A)Applies to support or property claims
Case and settlement conferencesSteps in most family cases
Motion (Forms 14 and 14A)Uses a Notice of Motion and an Affidavit in a family case

Consequences of hiding assets

The consequences can be serious. A court may refuse to enforce a separation agreement if a party did not fully disclose financial information. A court may also set aside a domestic contract, or a provision in it, if a party failed to disclose significant assets or significant debts or liabilities existing when the contract was made.

That said, it is a two-stage process. The applicant first has to prove a listed ground applies, and then the court decides in its discretion whether to set the contract aside, with fairness a consideration. A breach does not automatically void the contract.

In child support matters, failing to disclose a material increase in income is treated as blameworthy conduct and can move back the date from which retroactive support is ordered. Non-compliance with a court-ordered parenting arrangement can lead to a fine or jail.

What to do next

Frequently asked questions

Can I make my spouse show me their finances?

In a court case, each side must complete a financial statement and provide disclosure documents where support or property is claimed. If your spouse does not cooperate, a motion may be an option.

What if I already signed an agreement and later find hidden assets?

A court may set aside a domestic contract if a party failed to disclose significant assets or debts that existed when it was made. It is not automatic, because the court has discretion and fairness is a consideration.

Is there a deadline to act?

For equalization claims, the time limit is six years from the day of separation or two years from the day the divorce is final, whichever comes first. Other claims may have other limits, so get advice early.

Does this apply to common-law partners?

Common-law couples are not legally required to split property acquired while they lived together, though they may set property rights in a cohabitation agreement. How disclosure applies to your situation depends on the facts, so a lawyer can explain how your situation fits.
