Ontario sets out disclosure in Rule 13 of the Family Law Rules, O. Reg. 114/99. A party claiming only support serves Form 13; once property is in issue, the longer Form 13.1 is required, backed by the listed documents and a Form 13A certificate of financial disclosure. Married spouses then complete a net family property statement (Form 13B) to calculate the equalization payment under section 5 of the Family Law Act, and defined benefit pensions enter that calculation at the family law value set by the plan administrator under the Pension Benefits Act. Unmarried partners do not share in the equalization regime, but they can claim spousal support under section 29 after three years of cohabitation, or sooner with a child.
British Columbia writes the duty into the statute itself. Section 5 of the Family Law Act requires full and true information to resolve a family law dispute, whether or not anyone has gone to court. In the Supreme Court, Rule 5-1 of the Supreme Court Family Rules requires a sworn Form F8 with attached income documents, generally within 30 days of service; the Provincial Court uses Form 4. Partners in a marriage-like relationship of at least two years are spouses for property purposes. Interests held through a trust should be disclosed along with the family trust deed and its beneficiary terms.
Alberta applies the Family Property Act to married spouses and, since 2020, to adult interdependent partners. Disclosure is often exchanged voluntarily, but the formal tool is the Notice to Disclose (Form FL-17) under Rule 12.41 of the Alberta Rules of Court. A party served has one month to provide the listed information or object, after which the court can sanction non-compliance. Partners claiming child support outside a divorce rely on the Alberta Child Support Guidelines, which mirror the federal disclosure model.
Quebec follows a civil law system built on the family patrimony (articles 414 and following of the Civil Code of Québec) and applies its own child support rules, even in divorce proceedings. Our template is drafted for the common law provinces, and Quebec residents should adapt it with local counsel.
