How to approach a Form 13 or Form 13.1 financial statement: which form applies, what documents prove each figure, and the mistakes that cause the most delay.

⚖️ This is general information, not legal advice. It can't account for your specific situation. Use it to get oriented, then confirm the details with a licensed Ontario lawyer.

A financial statement is the document a family court case is built on. Once your case involves support, property or exclusive possession of the matrimonial home, the Family Law Rules require you to swear one — Form 13 for support-only claims, Form 13.1 where property or the home is also claimed — and serve it on the other side. It is easy to underestimate: the form looks like paperwork, but a wrong or careless figure on it can shape how a judge or a mediator sees your credibility for the rest of the case. This worksheet walks through the form section by section, with the documents that back up each part, so the numbers you swear to are ones you can actually stand behind.


Confirm which form you need

Form 13 is used where the case is about support only — no claim to property or to exclusive possession of the matrimonial home. Form 13.1 is used whenever property or the home is claimed, whether or not support is also in issue. Filing the wrong one is a common early mistake and usually means redoing the work, so confirm this with your lawyer before you start filling anything in.

Both forms are sworn — signed in front of a lawyer, commissioner or notary who confirms you understand you are swearing to its truth. Treat that seriously. A financial statement that turns out to be wrong, even through carelessness rather than dishonesty, is remembered by the other side and by the court.

Income

Expenses

The form asks for a realistic monthly budget, not an estimate pulled together the night before it is due. Go through several months of actual bank and credit card statements rather than guessing, and separate expenses that are truly ongoing from one-time costs that happened to fall in that period.

Where the expenses seem unusually low or high compared to your income, expect it to be questioned — either by the other side or by a judge — so be ready to explain anything that looks out of the ordinary.

Property and debts, if Form 13.1 applies

Getting it sworn and served

Once the figures are complete, review the whole form once more before swearing it — small arithmetic errors are common and are easy to fix now, harder to explain later. Your lawyer will arrange for it to be sworn and then serve it on the other side within the timelines set by the Family Law Rules.

Expect to update it. If your income, a debt, or an asset changes materially while the case is ongoing, the Divorce Act's duty to provide complete, accurate and up-to-date information means the statement should be updated, not left to go stale until the next conference.
