Key takeaways
  • Anyone making or answering a property claim in Ontario must serve and file a financial statement, and for property claims the form is Form 13.1.
  • Supporting documents, a net family property statement and corrections must follow set timelines, and missing or incorrect disclosure can lead to court orders and costs.
  • A separation agreement can be set aside if significant assets or debts were not disclosed when it was made.

When a marriage ends, dividing property fairly depends on both people being open about what they own and owe. In Ontario, that openness is not just good practice. It is a requirement once a property claim is in court.

This article explains the main disclosure steps, the documents that usually go with them, and what can happen if disclosure is missing or wrong. It is general information only, and a lawyer can confirm how it applies to your situation.

Why disclosure matters in property division

Equalization depends on the value of each spouse's property on the valuation date, less debts and certain deductions. Property is defined broadly and includes shares in a business or company. You cannot work out the numbers fairly unless both sides put their full picture on the table.

The spouse claiming a deduction or exclusion, such as a gift, an inheritance or a date-of-marriage deduction, has the onus of proving it. That makes records important for you as well as for the other side.

The financial statement

In an equalization application, each party must serve on the other and file with the court a sworn statement of their property, debts and other liabilities. It must cover the date of marriage, the valuation date and the date of the statement, plus claimed deductions and exclusions and certain disposals of property.

Under the Family Law Rules, a party making a property claim must serve and file a financial statement with the claim, and for property claims the form is Form 13.1. The responding party must serve and file one too, within the time for its answer or response.

Supporting documents and later statements

Within 30 days after the financial statement is due, a party to a Family Law Act Part I property claim must serve supporting documents, including statements for accounts and investments issued closest to the valuation date.

Before a settlement conference or trial, each party to a Part I property claim must serve and file a net family property statement, Form 13B. The timing differs by event:

EventWhen Form 13B is due
Settlement conference, requesting partySix days before
Settlement conference, other partyFour days before
Trial30 days before the earlier of the trial start and the trial sitting

If you discover that a document you served under Rule 13 is incorrect, you must promptly serve the corrected information.

What happens if disclosure is missing or incomplete

A court can also make interim or final orders restraining the depletion of a spouse's property in an equalization or title application.

Frequently asked questions

Which form do I use to disclose my finances in a property claim?

For property claims, the financial statement form is Form 13.1, served and filed with the claim, and the responding party does the same within the time for its answer or response. Before a settlement conference or trial you also file a net family property statement, Form 13B.

What if I find a mistake in my disclosure?

You must promptly serve the corrected information on the other party. Acting quickly helps avoid the problems that come from incomplete disclosure.

Can the court make the other spouse hand over documents?

Yes. If a required disclosure document has not been served or filed, the court may order it and must also order costs. The court may also order a non-party to produce a document and order questioning under oath.

Can a signed separation agreement be undone if my spouse hid assets?

A court may set it aside if a party failed to disclose significant assets, debts or other liabilities that existed when it was made. Whether that applies depends on the facts, so get legal advice promptly.
