Official form and filing instructions." --- # Statement of Family Patrimony ## Overview The **Statement of Family Patrimony** (Form IV) is a sworn financial disclosure document filed in Quebec family proceedings before the **Superior Court of Québec**. It is the instrument through which spouses and civil union partners formally declare, value, and partition the assets and debts falling within the family patrimony regime established by the _Civil Code of Québec_. Family patrimony is mandatory. Quebec law automatically subjects certain property categories to equal division upon separation, divorce, annulment, or death — regardless of whose name appears on title. This is sometimes referred to as the _patrimoine familial_ or family asset partition system. Completing the family patrimony statement accurately is not a procedural formality; it is the foundation of every patrimonial claim, a sworn declaration with legal consequences if false. > ⚠️ The family patrimony regime cannot be waived by a marriage contract. Completing this form at the correct valuation date and with full supporting documentation is the single most consequential step in any patrimonial proceeding. ## What Does the Statement of Family Patrimony Do? Filing the statement accomplishes disclosure, valuation, and claim simultaneously. Parts A and B establish asset values after exclusions under article 415 and deductions under article 418 of the _Civil Code of Québec_. Part C computes the net value for partition. Parts D and E address pension benefits accumulated during the marriage. Parts F through I allow a party to contest the regime's applicability, claim a compensatory payment under article 421 of the _Civil Code of Québec_, seek unequal partition under article 422, or specify division terms. Article 413 of the _Code of Civil Procedure_ requires this form in any proceeding where patrimonial rights are at issue. The sworn declaration carries full evidentiary weight — a false or incomplete family patrimony declaration carries legal consequences. > ⚠️ Parts F through I are active claim vehicles, not optional sections. A party who qualifies for a compensatory payment or unequal partition must assert it here. Omitting a valid claim in this form can forfeit it. ## When Do You Need the Statement of Family Patrimony? The form is required in any Superior Court family proceeding where patrimonial rights are in dispute: a divorce or legal separation claiming partition, a civil union dissolution, an annulment with patrimonial consequences, or a surviving spouse's claim on death. The form may also be prepared outside court as a working document in a notarially settled agreement, though it is not filed with the court in that context. The valuation date entered on the form substantially affects the partition result. That date is set by the applicable provisions of the _Civil Code of Québec_ or fixed by the presiding judge through a case management order. > ⚠️ If you are resolving patrimonial matters by notarized agreement outside court, confirm with your lawyer whether a filed Statement of Family Patrimony is still required or whether a negotiated patrimonial declaration suffices. ## Who Must File the Statement of Family Patrimony? Each party — applicant and respondent — prepares their own statement, reporting assets and debts from their respective position. Where values are contested, the two statements form the basis for dispute resolution before the court or in mediation. The form must be signed and sworn by the filing party — not by counsel — before a commissioner of oaths, notary, or other person authorized in Quebec to receive oaths. A party who disputes in Part F that the regime applies must still complete the form in full. If the court rejects the exemption, the complete statement on record prevents delay. > ⚠️ An incomplete or unsigned form will be rejected by the court registry. Where both spouses are represented, counsel typically prepares and reviews the form with their client before it is sworn and filed. ## How to Use the Statement of Family Patrimony? The form is available from the Superior Court of Québec's official website. It is an Excel-based file — do not retype values in formula-populated cells. Complete the header (district, docket number, party names, valuation date), then work through Parts A to I. Part A records excluded property under article 415 of the _Civil Code of Québec_ with grounds and values per party. Part B calculates net value across five asset categories — family and secondary residences, household movables for each, and family motor vehicles — after debts and after article 418 deductions of the _Civil Code of Québec_. Parts D and E require pension administrator statements; plans yielding only future benefit payments rather than a capitalized amount go in Part E. Swear the completed form before a commissioner of oaths or notary, then file at the Superior Court registry where proceedings are pending — in Montreal, at the Palais de Justice. 📍1, rue Notre-Dame Est, Montréal — VERIFY Serve a copy on the other party per the _Code of Civil Procedure_. > ⚠️ The Excel form auto-calculates totals in Parts B, C, and D. Overriding formula cells with manually typed values breaks the calculation chain without displaying an error, producing a silently inaccurate Value for Partition. ## Required Documents and Information Before completing the form, gather: - Municipal assessment notices and hypothec statements for each residence - A market appraisal where assessed value and market value differ materially - Vehicle registration and financing statements for each motor vehicle - Pension administrator statements showing the capitalized value accrued during the marriage - RRSP account statements as of the start and end of the marriage - Records supporting article 418 deductions: purchase contracts, notarial deeds, or bank records establishing pre-marital asset values, and records of any gift or inheritance invested in a patrimonial asset - Marriage certificate and any marriage contract or civil union agreement > ⚠️ Article 418 deductions require a supporting appendix showing full calculation detail. A deduction asserted without documentation is vulnerable to challenge and will rarely be accepted by the opposing party or the court. ## Family Law Considerations The family patrimony regime applies to all married and civilly united couples in Quebec regardless of matrimonial regime (_régime matrimonial_) and cannot be contracted out of. A couple who chose separation as to property under a marriage contract remain fully subject. Civil union partners are subject by operation of article 521.6 of the _Civil Code of Québec_. Equal partition is the default. Article 422 of the _Civil Code of Québec_ authorizes unequal partition where equal division would produce serious harm or a manifestly unjust result. Article 421 provides a compensatory payment where one spouse enriched the other's patrimony through labour or property beyond their own share. Pension classification matters. Defined benefit plans yielding a capitalized amount belong in Part D. Plans governed by the _Act respecting the Québec Pension Plan_ typically appear in Part E, with division handled through Retraite Québec's credit-splitting process rather than an immediate payment. > ⚠️ Misclassifying a pension plan between Part D and Part E produces a materially wrong partition calculation. If a plan does not provide a statement of capitalized entitlement, confirm with the administrator before placing it in Part D. ## Court Procedure and Timelines The family patrimony declaration is filed as part of the proceeding record at the Superior Court of Québec registry. In Montreal, family matters are heard before the Unified Family Tribunal. The court sets filing deadlines through a case management order. Patrimonial statements are generally exchanged alongside the financial disclosure required under the _Code of Civil Procedure_. A party who fails to file, or who submits an incomplete statement, risks adverse inferences, cost awards, and procedural sanctions. Timelines vary. Where parties agree on values after exchange, a consent judgment may be obtained within months. Contested disputes involving complex pensions, business interests, or alleged concealment extend considerably. > ⚠️ Missing the case management deadline for patrimonial statement exchange can trigger sanctions and delay the entire proceeding. If pension administrator statements or appraisals are not yet in hand, bring a motion to extend the deadline before it passes. ## Illustrative Scenario > 📌 **Parent A** and **Parent B** married in Montreal in 2004 and separated in 2023. **Parent A** holds the Côte-des-Neiges family residence in their name alone, purchased partly with an inheritance received during the marriage. **Parent B** accumulated substantial benefits under a government pension plan that does not yield a capitalized amount. Two disputes arise on the statement. **Parent A** claims an article 418 deduction for the inheritance invested in the residence, but the documentation is incomplete — only a partial bank record connects the inherited funds to the purchase. **Parent B** contests the deduction without challenging the property value. The Superior Court limits the deduction to the documented amount, increasing the net patrimony subject to partition. **Parent B**'s pension enters Part E rather than Part D: division flows through Retraite Québec's credit-splitting mechanism, producing no immediate cash payment to **Parent A** — a result with meaningfully different financial timing for both parties. ## Common Mistakes to Avoid **Choosing the wrong valuation date.** Confirm the applicable date under the _Civil Code of Québec_ or the case management order before completing the header — entering the separation date by default is a common and consequential error. **Omitting article 418 deductions.** Pre-marital values, gifts, and inheritances invested in patrimonial property are deductible if documented. Unclaimed deductions produce a higher partition liability than the law requires. **Misclassifying pension plans.** A plan providing only future benefit payments belongs in Part E, not Part D. Misclassifying it inflates the capitalized partition amount and may generate an order the owing party cannot meet. **Filing without sworn attestation.** The form has no legal force without the closing sworn declaration. Registry clerks reject unsigned forms, and the deadline does not pause while the error is corrected. ## Frequently Asked Questions ### Does the family patrimony regime apply to common-law couples in Quebec? No. The family patrimony rules of the _Civil Code of Québec_ apply only to married spouses and civil union partners. Common-law couples — regardless of relationship length or children — have no automatic right to patrimonial partition. ### Can parties agree to skip the Statement of Family Patrimony in court proceedings? Not where patrimonial rights are before the Superior Court. Article 413 of the _Code of Civil Procedure_ requires the form. Parties who resolve patrimonial rights by notarized agreement outside court may not need to file it, but must address each element the form captures. ### What are the consequences of hiding assets on the form? The statement is sworn under oath. Deliberate omissions expose a party to adverse inferences, cost awards, and potential contempt or perjury liability. Courts may order third-party disclosure from banks, pension administrators, or employers to verify values. ## When to Get Legal Help Family patrimony calculations involve compounding choices — valuation date, deductible amounts, pension classification, exclusion grounds — where a single error reshapes the partition outcome. Parties who self-represent routinely undervalue deductions or misclassify pension benefits, forfeiting entitlements the law would have granted. Legal advice is particularly important where the patrimony includes a defined benefit pension, a business interest, significant pre-marital assets, or a gift with an incomplete documentary record. A family law lawyer can identify whether a claim under article 421 or article 422 of the _Civil Code of Québec_ applies — entitlements many parties miss without counsel.
