  • Applicant’s full legal name (not nickname)

  • Applicant’s birth date and place of birth (ie: Edmonton)

  • Applicant’s parent(s)/guardian(s) names

  • If you are 16 or 17 years old, you will need the permission of everyone who has legal care of you before you may change your name.

  • You must notify your partner/spouse that you are changing your name if you are married or have signed a Joint Declaration of Conjugal Relationship paperwork.

  • If a police records check is required as part of your legal name change application, download the Criteria for a Police Record Check for a Change of Name form to ensure that the police agency performing the check fulfills all requirements. 

This Declaration must be Notarized/Commissioned before submission. Please note that the entire package must be completed before it can be Notarized/Commissioned.

To change your name legally, you will need to fill out a name change application and submit it to your government agency, such as the Vital Records office or the court. You might also have to provide documentation to support your name change, such as a marriage certificate or a divorce decree.

These requirements may vary by jurisdiction, but generally, you will need to be over the age of 18 (depending on the jurisdiction) and of sound mental state. You may also have to provide documentation (such as divorce or marriage certificates).

In most cases, you can choose your name to be anything you want, as long as it is not being used for fraudulent purposes and to avoid any legal obligations. However, some jurisdictions may have restrictions on the types of names that can be used.

Yes, it is important to notify every one of your name change, including the government, your employer, financial institutions or anyone with whom you do business. You also need to update your identification documents, such as your driver’s license, passport, social insurance number, and other documents, to reflect your new name.

There may be a fee for changing your name, depending on where you live. This usually covers the costs of processing your name change application and issuing any new identification documents.
