Co-Parenting in Quebec: Legal Aspects 2026

Co-parenting in Quebec is a legally recognized family model. Here are the key legal aspects to understand before starting your project.

1. Parental Authority

In Quebec, parental authority is exercised jointly by both parents as soon as filiation is established. Both co-parents have equal rights and responsibilities toward the child.

2. The Written Co-Parenting Agreement

Although not legally mandatory, a written agreement drafted with a notary or lawyer is strongly recommended. It should cover custody arrangements, financial contributions, decision-making and more.

3. Union Parentale (since June 30, 2025)

Since June 30, 2025, Quebec introduced the "union parentale" regime which provides additional protections for de facto spouses with a common child. This may apply to some co-parenting situations.

4. Our Recommendation

Always consult a notary or family law lawyer before starting any medical process. A clear legal framework protects everyone, especially the child.
