What is a parental union in Quebec?
Short answer
In Quebec, the parental union is a legal regime that applies automatically to de facto spouses who become the parents of a common child, by birth or adoption, after June 29, 2025. No steps are required: the regime applies on its own as soon as those two conditions are met.
In detail
The Quebec government confirms this clearly in its official FAQ: “It applies automatically as soon as the criteria are met, that is, being de facto spouses and having a common child after June 29, 2025. You therefore have nothing to do and the regime applies automatically.”
Two points matter here. First, the date is about filiation, not birth: a child born before June 30, 2025 but adopted after that date does create a parental union, because you became the parents of a common child after June 29, 2025. Second, a person cannot be in two unions at the same time: if your spouse is separated but still married to someone else, the parental union cannot begin until they are divorced.
The parental union creates rights and obligations between the spouses themselves. It changes nothing about your rights and obligations toward your children: neither custody nor child support is affected by this regime. It also has no effect on your income tax returns with Revenu Québec (Quebec's revenue agency) or with the Canada Revenue Agency.
What to document
The exact date of birth or of the adoption judgment of your common child (that is what triggers the regime), the date your life together began, and a copy of any notarial act signed between you. If you have a child born before June 30, 2025 and you opted in voluntarily, keep the notarial act or the written contract signed before two witnesses.
Put your facts in writing, free. Writing your version down early, keeping your documents dated and preparing your questions for a lawyer: the tool is there to document, never to advise.
