Rights of de facto spouses
The Civil Code of Québec does not grant any matrimonial rights on property to de facto spouses
The rules concerning matrimonial regimes and family patrimony do not apply to de facto spouses, even if they have children and regardless of the length of the conjugal relationship. However, a former de facto spouse may have to pay support payments for the children.
However, one spouse may have a debt to another for other reasons (business, contract, joint ownership, etc.)
Moreover, like married or civil union spouses, de facto spouses may agree to share their property, even if no debt is owed.
