In order to change your name in Alberta, you must be at least 18 years of age, a resident of the Province (and you must remain one throughout the process), and you must provide valid ID. You may be younger than 18 years of age if you are legally married, living in an adult interdependent relationship, or the parent or guardian of a child.
If you are eligible, you must go to a registry agent office and obtain and complete the Legal Change of Name Application form. You must provide all required supporting documents, such as proof of name/marital status/relationship to a child or ward. Additionally, you must surrender all Canadian birth and marriage certificates for anyone having their name changed.
For each person 12 years of age or older, fingerprinting is required.
Once all of the above steps have been completed, take the completed forms and all supporting documentation to a registry agent office, along with the required fees.
