Legal Name and Sex Designation Change
This service is available for adult first name and/or sex designation changes, minor first name and/or sex designation changes, and parental designation changes (being legally classified as “mother”, “father” or “parent”), whether you are a Canadian citizen or not.
What does it mean for a name/sex designation change to be "sworn in"?
When a person wishes to change their legal first name and/or sex designation (if it says “M”, “F” or “X” on your legal documents), their request must be sworn. That is, a Commissaire à l’assermentation must “approve” the request, confirming that it is true.
Many members of our team are Commissaires à l’assermentation, so they can swear in your application and walk you through the process!
You can either :
- fill out the forms yourself, in part or in full, print them, and come to TransEstrie to complete them and have them sworn in;
- Web page that explains how to change your legal sex designation
