Why Does Canada Use the Term Marriage Contract Instead of Prenuptial Agreement?
Provincial family law statutes, including Ontario's Family Law Act section 52, BC's Family Law Act, and Alberta's Matrimonial Property Act, use the term marriage contract to describe a domestic agreement entered into before or during marriage. The Canadian term encompasses both pre-marriage and post-marriage contracts and is the only legally recognized form. Calling it a prenuptial agreement carries no legal weight in Canada, although the concept is identical.
What Are the Legal Requirements for an Enforceable Marriage Contract in Canada?
Each spouse must provide full and honest financial disclosure of all assets, debts, and income. Each spouse must obtain independent legal advice from a separate lawyer. The contract must be in writing and signed. There must be no duress, undue influence, or unconscionability. The Supreme Court of Canada in Hartshorne v Hartshorne and Miglin v Miglin set the standard: courts will set aside contracts that fail any of these tests.
What Assets Can a Canadian Marriage Contract Protect from Equalization?
A contract can exclude specific assets from the net family property calculation that otherwise applies on marriage breakdown. Common exclusions include pre-marriage business equity, professional practices, inheritances, gifts from third parties, and identified investment accounts. The matrimonial home receives special treatment under Ontario's Family Law Act and cannot be excluded as readily as other assets.
