Spouses in Quebec

As indicated in our family patrimony post, family patrimony does not apply to common-law spouses. Similarly, matrimonial regimes are only available to married or civil union spouses.

In the event of the breakdown of a de facto union, each spouse retains full ownership of the property acquired before and during the union.

Spousal support can only be claimed between married or civil union spouses. Therefore, common-law spouses cannot claim spousal support.

However, common law spouses can enter into a de facto union agreement in which the rules of family patrimony and the matrimonial regime can be applied. Alimony for former spouses can also be provided for in such an agreement.

NB: Please note that this is a concise explanation for information purposes.
