Prenuptial agreements, often called “prenups,” are legal contracts created before marriage. While some people see them as unromantic, they are actually practical tools for financial clarity. A prenup allows couples to decide in advance how assets, debts and financial responsibilities will be handled if the relationship ends. This can significantly reduce conflict during separation. These agreements are especially useful when one or both partners have significant assets, own a business, or have children from previous relationships. For a prenup to be valid in Canada, it must meet certain conditions. Both parties must provide full financial disclosure, and the agreement must be signed voluntarily without pressure. Independent legal advice is also strongly recommended. Courts generally respect prenups, but they may set them aside if they are unfair or if proper procedures were not followed. Prenuptial agreements can also address spousal support, though courts may still review these provisions for fairness at the time of separation. Rather than planning for failure, a prenup creates transparency and mutual understanding. It allows couples to enter marriage with clear expectations and peace of mind.
