Ontario Divorce Financial Disclosure: What You Must Disclose and How

Financial Disclosure Is Not Optional

When property, support, or other financial relief is at issue in an Ontario family law proceeding, financial disclosure is mandatory. Both spouses must provide a complete and honest picture of their finances — not because the court wants to be intrusive, but because every financial decision in a divorce (property division, spousal support, child support) depends on accurate numbers. A divorce-only application may have different disclosure requirements. Without full disclosure where it is required, the court cannot determine fair outcomes, and an agreement signed without disclosure is vulnerable to being set aside later.

Where disclosure is required, the obligation applies regardless of whether your divorce is contested or uncontested, and regardless of whether you have a lawyer or are self-represented. It applies equally to both spouses. Hiding assets, understating income, or failing to disclose debts is not just bad strategy — it can result in court sanctions, adverse cost awards, and in extreme cases, the setting aside of an otherwise final settlement years after it was signed.

Form 13.1: The Detailed Financial Statement

Form 13.1 (Financial Statement — Property and Support Claims) is the primary disclosure document in Ontario divorce proceedings. It is required whenever property division or spousal support is claimed — which is nearly every divorce that involves more than a divorce-only order.

The form requires you to list:

Part 1 — Income. Your gross annual income from all sources: employment, self-employment, investments, rental income, government benefits, pension income, and any other revenue. Attach your most recent income tax return and notice of assessment as supporting documentation.

Part 2 — Expenses. Your monthly living expenses in detail: housing (mortgage/rent, property tax, insurance, utilities), transportation, food, personal care, medical expenses, child-related costs, debt payments, and discretionary spending. This section is used to assess the need for and reasonableness of spousal support.

Part 3 — Assets on the valuation date. Everything you own on the date of separation: real property, vehicles, bank accounts, investments (RRSPs, TFSAs, non-registered accounts), pensions, life insurance policies, business interests, personal property of significant value (jewellery, art, collections), and money owed to you. Each asset must be valued as of the valuation date.

Part 4 — Debts on the valuation date. Everything you owe: mortgages, lines of credit, credit cards, car loans, student loans, personal loans, and any other liabilities.

Part 5 — Assets and debts on the date of marriage. The same categories as Parts 3 and 4, but valued as of the date you married. This information is needed to calculate your net family property — the difference between what you had on the valuation date and what you had on the marriage date represents the wealth accumulated during the marriage.

Part 6 — Excluded property. Items that are excluded from your NFP under section 4(2) of the Family Law Act: inheritances, gifts from third parties received during the marriage, personal injury awards, and life insurance proceeds. These exclusions reduce your NFP, but you must identify them specifically and prove their current value with documentation.

What Documentation You Need

The financial statement is not just a form — it is accompanied by supporting documentation that proves the numbers are real. The minimum documentation typically required:

Gathering marriage-date documentation is often the hardest part. If you married 15 years ago, finding bank statements from that date may require requesting archived records from your financial institutions — some charge fees for this, and some cannot retrieve records beyond a certain age.

Form 13B: The NFP Statement

Form 13B (Net Family Property Statement) is the summary document that pulls together the information from Form 13.1 into the equalization calculation. It is a concise form that shows:

1. Your NFP (valuation-date assets minus valuation-date debts minus marriage-date net worth minus excluded property)
2. Your spouse's NFP (from their Form 13.1 and 13B)
3. The equalization payment (half of the difference between the higher and lower NFP)

Form 13B is filed closer to the resolution stage of the case — either before a settlement conference or before trial. It is the document the judge uses to understand each party's property position at a glance.

Consequences of Incomplete or Dishonest Disclosure

Ontario courts take disclosure obligations seriously, and the consequences of non-compliance are significant:

Adverse inferences. If you fail to disclose an asset or provide inadequate documentation, the court may infer that the undisclosed information would have been unfavourable to you. The judge can assign a value to the missing asset based on the available evidence, even if that value is higher than the asset's actual worth.

Cost penalties. A spouse who forces the other side to bring a motion to compel disclosure will typically be ordered to pay the costs of that motion — regardless of the ultimate outcome of the case.

Setting aside agreements. Under section 56(4) of the Family Law Act, a court can set aside a separation agreement or court order if a party failed to disclose significant assets or debts before the agreement was signed. This can happen years after the divorce is finalized if the hidden assets are discovered later.

Contempt of court. In extreme cases of deliberate concealment, the non-disclosing party can be found in contempt of court, which carries penalties including fines and imprisonment.

Practical Tips for Self-Filers

Start gathering documents early. The disclosure process is the most time-consuming part of the divorce for most people. Begin collecting bank statements, tax returns, and asset valuations as soon as you know separation is coming.

Remember to redact. Under Rule 13 of the Family Law Rules, sensitive personal identifiers (including SINs, full bank account numbers, and credit card numbers) must be blacked out before filing documents with the court. Keep unredacted copies for your own records, but file only the redacted versions.

Be honest about valuations. For real property, use a professional appraisal or at minimum a well-documented comparative market analysis. For vehicles, use a recognized valuation source like Canadian Black Book. For pensions, request a statement from your pension administrator rather than guessing.

Disclose everything, even if you think it is excluded. An inherited cottage is excluded property, but you still need to list it and identify it as excluded. The other spouse and the court need to see the full picture and verify that the exclusion is valid.
