Ontario Form 13.1 Financial Statement: What You Need and How to Fill It Out

Form 13.1 is the financial backbone of every Ontario divorce involving property claims. It's a sworn document — you sign it under oath — and it requires you to disclose every asset, every debt, every source of income, and every monthly expense. Mess it up and your equalization calculation is wrong. Lie on it and you face court sanctions.

Filing the wrong form is the first mistake people make: Form 13.1 is for property and support claims together. If your case involves only child or spousal support with no property division, you use the shorter Form 13 instead.

When Form 13.1 Is Required

Under the Ontario Family Law Rules (Rule 13), you must file a sworn financial statement whenever there are claims for:

• Equalization of net family property
• Exclusive possession of the matrimonial home
• Property division combined with spousal or child support

The statement must be served and filed before your first case conference. It also has staleness rules — if your financial statement is too old by the time a court event happens, you must file an updated one:

• Case conference or settlement conference: statement must be less than 60 days old, served at least 6 days before (applicant) or 4 days before (respondent)
• Motion: less than 30 days old
• Trial: less than 40 days old, served at least 30 days before trial

If nothing has changed, you can file Form 14A (an affidavit confirming no material changes) instead of redoing the entire 13.1.

Documents You Need Before Starting

Gather these before you sit down with the form:

Income documentation: Last three years of tax returns (Notice of Assessment), current pay stubs, business financial statements if self-employed, investment income statements.

Asset documentation (separation date): Bank account statements, investment and brokerage statements, RRSP/TFSA balances, real estate appraisals or market assessments, vehicle valuations, pension statements (or FSRA Family Law Value if available), life insurance cash surrender values.

Asset documentation (marriage date): The same categories, but from the date of marriage. This is where most people struggle — who keeps bank statements from their wedding day? Older accounts may require requests to financial institutions for historical records.

Debt documentation: Mortgage statements, credit card balances, lines of credit, student loans, car loans, tax liabilities.

Excluded property documentation: Inheritance letters, gift documentation, personal injury settlement records, and tracing records showing the funds remained segregated.

Common Mistakes on Form 13.1

Missing marriage-date values. The equalization calculation depends on your net worth at marriage. If you can't document marriage-date assets, you lose the deduction — inflating your NFP and increasing your equalization obligation.

Valuing assets at purchase price instead of fair market value. Form 13.1 requires current market value on the separation date, not what you originally paid. Real estate, vehicles, and investments must be valued at separation-date market rates.

Forgetting the matrimonial home exception. If you owned the family home before marriage, you still cannot deduct its marriage-date value from your NFP. People who've owned their home for years before getting married routinely miss this — it's often the single largest line item in the equalization calculation.

Omitting contingent liabilities. Income tax that will be owed on RRSP withdrawals or pension payments is a real liability, even if it won't be triggered for years. Failing to note this makes the financial picture look better than it is.

Form 13A: The Certificate of Financial Disclosure

Form 13A accompanies Form 13.1 and is equally mandatory. It's a checklist confirming that you've provided specific categories of supporting documents to the other side — bank statements, tax returns, appraisals, and so on.

Filing Form 13.1 without Form 13A is an incomplete disclosure. Courts take this seriously because the entire equalization system depends on both spouses having access to accurate financial information.

Preparing Your Financial Disclosure

The quality of your Form 13.1 directly determines the accuracy of your equalization calculation and the enforceability of any separation agreement built on it. Rushing through it or guessing at values creates problems that compound through every subsequent step of the divorce.

The Ontario Divorce Financial Split Guide includes a financial disclosure tracker that maps every required document category to the corresponding Form 13.1 section, so you can systematically gather your records before sitting down with the form.
