A prenuptial agreement (commonly called a prenup) is a legal contract signed by two people before they marry, outlining how assets, debts, and property will be divided if the marriage ends in divorce or death. These agreements can protect pre-existing assets, business interests, and inheritances, and may address spousal support arrangements. In Canada, family law is provincial jurisdiction, so the enforceability and requirements for prenuptial agreements vary by province. Courts generally uphold these agreements if both parties had independent legal advice, made full financial disclosure, and signed voluntarily without pressure. Also called marriage contracts or domestic contracts.
