Form 13 — the financial statement for support-only cases.
Form 13 is the shorter financial statement — the one you file when the case is about support and there is no property claim. It sets out your income and expenses so support can be worked out on real numbers. Here is what it covers and when it is the wrong form.
Support only
Form 13 is for cases about support with no property claim. If property is in play, you file Form 13.1 instead.
Income is the engine
Child and spousal support are driven by income, so the income sections are where accuracy matters most.
Sworn and disclosed
You swear it and back it with disclosure. Understating income tends to surface and cost more than it saves.
Form 13 is the Financial Statement (Support Claims). You use it when child support, spousal support, or both are in issue and no one is claiming property or equalization. It is the lighter of the two financial statements because it does not have to build the equalization calculation — it focuses on income, expenses, and a summary of assets and debts.
The moment property or equalization enters the case, Form 13 is the wrong form and you file Form 13.1 instead. That single distinction — is property claimed or not — is what decides which financial statement you complete, so it is worth settling before you start filling anything in.
Support is calculated on income, so the income parts of this form carry the most weight. This is a map of the form, not advice about your support numbers, and the figures you swear to here feed directly into what you pay or receive.
What Form 13 covers
The form sets out your income from all sources, a detailed picture of your monthly expenses, and a summary of your assets and debts. For child support, the income figure drives the Federal Child Support Guidelines table amount. For spousal support, income and the budget picture both feed the analysis of whether support is payable and how much.
Because support runs on income, self-employment income, bonuses, and income that does not show up cleanly on a T4 get particular attention. The goal of the form is an honest, complete picture of what you actually earn and spend, backed by documents.
The parts of Form 13 that trip men up
The most common mistake is treating the expense section as a wish list or padding it to look poorer. Inflated or unsupported expenses are easy to attack and undercut your credibility on the numbers that matter. A realistic budget you can document reads far better than a dramatic one you cannot.
The second is understating income, especially where some of it is variable or self-employment income. Courts can impute income to a payor who is not being straight about earnings, so hiding income tends to backfire. The third is filing Form 13 when there is actually a property claim on the table — that means you needed Form 13.1, and the case gets delayed while you redo it.
Filing, disclosure, and updates
Form 13 attaches to the application or answer that raises the support claim and is served on the other party with the disclosure that proves your income — recent pay statements, tax returns and notices of assessment, and records for any other income. Complete disclosure up front tends to shorten the whole process.
If your income changes, the court can ask for an updated statement so support is set on current numbers. Keeping your income documentation current and organized makes conferences and negotiations move faster and leaves less room for dispute about the figures.
