In Knight v. Knight (2019 ONCA 538), an Ontario appellate court upheld a $490,000 cost award against a spouse who refused to provide financial disclosure. In Horrocks v. McConville (2022 ONSC 6885), a party received a 30-day jail sentence and $2,000-per-day fines for the same failure. These are not outliers. Financial disclosure is the foundation of every family law proceeding in Canada, and courts treat non-compliance with increasing severity.
But the specific rules — which forms to file, when to file them, and what consequences attach — vary dramatically from province to province. This guide provides a comparative analysis of disclosure obligations across all Canadian jurisdictions, organized to help you understand not just your own province's rules, but how they compare nationally.
The Federal Foundation: Divorce Act s. 7.4
The 2021 amendments to the Divorce Act (Bill C-78, in force March 1, 2021) introduced a statutory duty to disclose. Section 7.4 requires that every party to a Divorce Act proceeding provide "complete, accurate and up-to-date information" when required under the Act.
This obligation applies nationally, but it is the provincial rules that supply the procedural details — which forms to complete, which documents to attach, and what timelines to follow.
The federal Child Support Guidelines, sections 21 through 25, add further requirements. Courts may impute income under section 23 when disclosure is inadequate — typically resulting in higher support obligations than actual income would produce.

Key Provincial Differences
Ontario: The Two-Form System
Ontario is the only province that uses two different financial statement forms depending on the nature of the claim. Form 13 is used when the case involves only child support or spousal support with no property claims. Form 13.1 is used when the case includes any property or debt claim. Filing the wrong form is a common procedural error flagged by Ontario registrars.
Form 13.1 is substantially longer because it requires a complete inventory of assets and liabilities at both the date of marriage and the valuation date, plus a net family property calculation. Ontario also requires Form 13A (Certificate of Financial Disclosure), and its update obligations are among the strictest: financial statements must be refreshed at least 6 days before any case conference, settlement conference, motion, or trial if the information is more than 30 days old. Supporting documents — including 3 years of tax returns, Notices of Assessment, pay stubs, and investment records — must be served within 30 days of the financial statement due date.
British Columbia: Two Courts, Two Forms
BC is one of several provinces — along with Alberta, Manitoba, and Newfoundland — that operate two parallel court systems for family law, each with distinct form requirements. The Provincial Court handles parenting and support but not property division. The Supreme Court handles all family matters including property.

Form F8 is the Supreme Court financial statement, covering income, expenses, assets, debts, and extraordinary expenses. It must be served within 30 days of filing a Notice of Family Claim. Form 4 is the Provincial Court form, used for support matters only and due before the first case conference. BC also requires specific disclosure from trust beneficiaries and self-employed parties, including 3 years of business financial statements.
Alberta: Single Form, Full Coverage
Alberta uses a single comprehensive form — Form FL-17 — for all family law matters in the Court of King's Bench. Disclosure must be filed within 20 days of receiving a request, and matters will not progress past the first Judicial Dispute Resolution session without it. Alberta extends property division rights to "adult interdependent partners" (common-law, 3+ years or child together), who face the same FL-17 obligations as married spouses.
Quebec: A Fundamentally Different Regime
Quebec stands apart from every other Canadian jurisdiction. Its family law derives from the Civil Code, not common law. Three structural differences affect disclosure:
- Family Patrimony (patrimoine familial). A mandatory equal-division regime covering family residences, furniture, vehicles, RRSPs, and QPP/CPP contributions. Form IV addresses this partition.
- Own child support guidelines. Quebec does not use the federal Child Support Guidelines. Schedule I is used to calculate child support under Quebec's own model.
- Sworn declarations. Form III (Statement of Income, Expenses, and Balance Sheet) is used for spousal support, with declarations under Article 444 of the Code of Civil Procedure.
Quebec requires both federal and provincial tax returns (Revenu Quebec). Common-law partners historically had no property or support rights at all; new "parental union" rules (effective June 2025) create limited obligations for unmarried parents only.
Manitoba: The Triage Gate
Since February 2019, Manitoba's Family Division Triage Model requires all four parts of Form 70D to be completed — Annual Income, Monthly Expenses, Assets, and Debts — even if some parts have low relevance. Matters cannot progress past Pre-Triage Screening until disclosure is satisfied. Manitoba may also impose penalties for incomplete disclosure and extends property division to common-law partners who have lived together for 3 or more years.
Nova Scotia and Other Provinces
Nova Scotia uses separate forms for different financial components: Form FD3 (income), Form FD4 (special expenses), Form FD6 (expenses for spousal support), and Form FD7 (property). Parties complete only the forms relevant to their claims. Financial statements must be filed in all cases involving dependent children, even uncontested ones.
Saskatchewan (Form 15-26 under the King's Bench Rules, Part 15) is one of the few provinces that permits a waiver of financial statements via Form 15-28A. New Brunswick (Form 72J) has particularly high disclosure requirements in shared parenting arrangements. PEI adopted Ontario's Rules of Civil Procedure in 1990 and follows a structurally similar framework. Newfoundland and Labrador uses Form F10.02A, a sworn multi-part financial statement, along with Form F11.02A (Demand to Disclose).
The territories — Yukon (Form 94/94A), Northwest Territories, and Nunavut (Form 8 under a unified court system) — have simpler forms and processes.
Common-Law vs. Married: The Disclosure Gap
One of the most significant cross-provincial differences is whether common-law partners face the same property disclosure obligations as married spouses:
- Full property disclosure required: BC (after 2 years of cohabitation), Alberta (adult interdependent partners, 3+ years or child together), Saskatchewan (after 2 years), and Manitoba (after 3 years) all extend property division — and therefore full property disclosure — to common-law partners.
- Support disclosure only: Ontario, Nova Scotia, New Brunswick, PEI, and Newfoundland do not provide property division for common-law partners. Disclosure is limited to income and support-related information.
- Quebec: Limited new obligations for unmarried parents only (since June 2025).
The practical impact is substantial. In BC, a common-law couple separating after 2 years faces the same comprehensive Form F8 disclosure as a divorcing married couple. In Ontario, an unmarried couple has no property division framework — regardless of relationship duration — and only discloses for support purposes.
Cross-Provincial Cases
Jurisdiction under the Divorce Act is based on ordinary residence: one spouse must have been ordinarily resident in the province for at least one year before filing. Either spouse can file where they have this residency, and the other spouse then follows the procedural rules — including disclosure forms — of the filing province.
This creates meaningful strategic considerations. A party filing in Ontario will complete Form 13.1 — one of the most detailed financial statements in Canada — while the same matter filed in Alberta would use the simpler FL-17. For support enforcement across provincial boundaries, each province has an Interjurisdictional Support Orders (ISO) Act. Under ISO proceedings, disclosure follows the rules of the province where the order is being sought, not where the applicant resides.
Consequences of Non-Disclosure
While enforcement mechanisms vary by province, the consequences are severe and broadly consistent: income imputation at higher-than-actual levels, adverse inferences (courts may assume undisclosed assets exist), cost awards (up to $490,000 in Knight v. Knight), striking of pleadings, contempt of court including imprisonment, and reopened settlements years after the fact. Province-specific penalties include BC's up to $5,000 under the Family Law Act (s. 213) and Manitoba's $5,000 non-disclosure penalties plus the Triage hard gate.
Common Deficiencies to Avoid
- Filing the wrong form — especially Ontario's Form 13 vs. 13.1
- Missing Notices of Assessment — a common deficiency across all provinces
- Stale information — financial statements based on income data more than 6 months old
- Missing sworn signatures — every province requires sworn or affirmed financial statements; unsigned forms are returned
- Incomplete property schedules — particularly the net family property calculation at date of marriage in Ontario's Form 13.1
- Undisclosed corporate structures — self-employed parties frequently omit corporate financial statements
- Inconsistent income figures — the income in your financial statement (Line 15000 total income, deductions, adjustments) should match your support calculation inputs. Using different figures creates credibility issues that can undermine your case.
How Divorcepath Can Help
Divorcepath addresses the consistency and complexity problems that make financial disclosure challenging. Income, expense, and asset information entered in the child support calculator or spousal support calculator can auto-fill financial statement forms, ensuring your disclosure documents match your support calculations. Divorcepath generates the correct province-specific form — whether Ontario's Form 13.1, BC's Form F8, Alberta's FL-17, or another provincial form — so you never file the wrong one. Its built-in document editor lets you review and finalize everything before filing.
Getting disclosure right from the start is the single most effective way to reduce litigation costs, accelerate settlement, and avoid the severe consequences courts impose for non-compliance.
