Amendments to the Regulation respecting supplemental pension plans effective 4 January 2018, as well as
division V – Transfer of benefits between spouses 
of the
Regulation respecting supplemental pension plans, to find out the rules for partition applicable to spouses in a civil union, the changes to the payment methods applicable to the former spouse, and the calculation of member benefits after partition.
The
Civil Code 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 (common law) 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 legal spouses, de facto spouses may agree to share their property, even if no debt is owed.
