Key takeaways
  • Form 13 is for support-only claims, and Form 13.1 is used whenever there is a property or exclusive-possession claim.
  • Some child support claims at the table amount do not need a financial statement.
  • Leaving out significant assets can lead to costs now or to a contract being set aside later.

If you are claiming support or property in an Ontario family case, the court expects you to lay out your finances in a standard form. Choosing the right form and completing it fully is one of the most important steps in your case.

This article explains which form applies, what else you may need to serve, and the mistakes that cause trouble.

Who must file a financial statement

A party making a claim for support, property or exclusive possession of the matrimonial home must serve and file a financial statement, on Form 13 or 13.1.

There is an exception. If your only support claim is for child support in the table amount under the Child Support Guidelines, and there is no property or exclusive-possession claim, you are not required to file a financial statement.

A respondent who makes their own claims in their Answer must also provide financial disclosure if support or property is in issue.

Form 13 or Form 13.1

Your claimsForm to use
Support only, with no property claim and no claim for exclusive possession of the matrimonial homeForm 13 (Support Claims)
Any property claim or claim for exclusive possession, whether or not support is also claimedForm 13.1 (Property and Support Claims)

Form 13 is used where support is claimed with no property claim and no claim for exclusive possession of the matrimonial home. Form 13.1 is used whenever there is a property or exclusive-possession claim, whether or not support is also claimed.

What else to serve with it

In support cases, a party must also serve certain documents. These include:

If your case is started by application, financial disclosure goes in with the Continuing Record when your case involves child support, spousal support or property.

Common mistakes and why they matter

If a party has not served or filed required financial documents, the court may, on motion, order them to do so, and if it makes that order it must also order the party to pay costs.

The risk can come after settlement too. A court may set aside a domestic contract, or a provision in it, if a party failed to disclose significant assets to the other.

What to do next

Frequently asked questions

Do I always need a financial statement?

No. If your only support claim is child support in the table amount, and there is no property or exclusive-possession claim, you are not required to file one. In other support, property or exclusive-possession claims, one is required.

Which form do I use if I claim both support and property?

Use Form 13.1 (Property and Support Claims). It applies whenever there is a property or exclusive-possession claim, whether or not support is also claimed.

What happens if the other side does not give disclosure?

The court may, on motion, order them to serve or file the required documents. If it does, it must also order them to pay costs.

Can leaving out an asset affect a separation agreement?

Yes. A court may set aside a domestic contract or a provision in it if a party failed to disclose significant assets. A lawyer can explain how this might apply to your situation.
