Does a step-parent have any rights over their spouse's child?
Short answer
In Quebec, a parental union requires a child common to both spouses: a blended family where each parent has children from a previous relationship, with no child in common, is not covered by the regime. The parental union creates rights between the spouses themselves, and not between one spouse and the other's child.
In detail
The official FAQ addresses this case directly: “My spouse and I had children with our former spouses before forming a blended family. We have no children together. Have we been in a parental union since we became a couple? ANSWER: No. To be in a parental union, you and your spouse must have a child together after June 29, 2025.”
The parental union regime is, moreover, about relations between spouses — patrimony, family residence, succession — and not about relations between one spouse and the other's child.
There is, however, a separate avenue worth knowing about: the rules on a child's personal relations were revised to provide for the possibility of maintaining relations with a parent's former spouse, in the child's interest and taking into account the increased weight given to the child's consent.
What to document
The history of the bond between the step-parent and the child: how long you lived together, the role played day to day, attendance at school and medical events, dated photos and exchanges. If you are spouses with no child in common, a written cohabitation agreement remains the main tool for organizing your property.
