Quick answer

Financial disclosure is the exchange of an honest, documented picture of your finances when a case involves child support, spousal support, or dividing property — and it's a two-way obligation, not a tactic. In Ontario it usually centres on a sworn financial statement plus supporting documents like recent tax returns and notices of assessment, pay stubs, and bank, investment, pension, and debt statements. Which financial statement you use depends on the issues: broadly, Form 13 (Financial Statement — Support Claims) for support-only cases, and Form 13.1 (Financial Statement — Property and Support Claims) when property is also involved. Missing or late disclosure is a common cause of delay; full and timely disclosure protects your credibility, and a lawyer can advise on complex situations.

If your case involves child support, spousal support, or dividing property, financial disclosure is unavoidable — and it's one of the most common reasons cases get stuck. Disclosure simply means giving the other side (and the court) an honest, documented picture of your finances. Getting it organized early keeps your case moving and builds your credibility. This is general information, not legal or financial advice.

What financial disclosure is

Disclosure is the exchange of financial information so that support and property can be worked out fairly. In Ontario family court this usually centres on a sworn financial statement plus supporting documents that back up the numbers. Both sides disclose — it's a two-way obligation, not a tactic.

Form 13 and Form 13.1

Which financial statement you use depends on the issues. Broadly, Form 13 (Financial Statement — Support Claims) is used when the case is about support only, and Form 13.1 (Financial Statement — Property and Support Claims) is used when property is also involved. These are sworn documents, so accuracy matters. Confirm what applies to you using the official Family Law Rules and forms.

The documents you'll likely need

Beyond the form itself, you'll generally need to back up your income and finances. Commonly that includes:

  • Recent income tax returns and notices of assessment
  • Recent pay stubs or proof of current income
  • Bank, credit card, investment, and pension statements
  • Documents for property, debts, and major assets
  • Proof of special or extraordinary child expenses, if relevant

If you're self-employed or your income is complicated, expect to provide more — and consider getting advice on how to present it.

Why complete, honest disclosure matters

Missing, late, or incomplete disclosure is one of the biggest causes of delay, extra costs, and frustration in family court — and it damages credibility. Courts take disclosure obligations seriously. Full and timely disclosure, even when it's inconvenient, almost always serves you better than dragging it out.

Keep it organized — and keep it current

Treat disclosure as a living folder, not a one-time scramble. Keep your statements and documents together, labelled and dated, and update them as your situation changes (you may need to update a financial statement as a case goes on). An organized document set makes completing the form — and answering questions about it — far less stressful.

Frequently asked questions

What is a financial statement in Ontario family court?
It's a sworn document setting out your income, expenses, assets, and debts, filed when support or property is at issue. Depending on the issues you'll generally use Form 13 (support claims) or Form 13.1 (property and support claims), along with supporting documents. Check the official forms for what applies.
What happens if someone doesn't provide financial disclosure?
Incomplete or late disclosure commonly causes delays and added costs, and courts have ways to address it — including drawing adverse inferences, ordering disclosure, imputing income, or awarding costs. Practically, withholding disclosure tends to hurt the person who does it. A lawyer can advise on your situation.
Do both people have to disclose their finances?
Yes — financial disclosure is generally a mutual obligation when support or property is in issue. Both parties provide a financial statement and supporting documents so the matter can be resolved fairly.
