If your passport currently has your surname at birth, you may have your spousal surname added. Send a letter of request, along with your passport, the required fee, and your marriage certificate or a supplementary identification issued in your married surname. This same process applies if you are in a common-law relationship and would like to add your spouse's surname to your passport. In addition to the previous documentation, you will need to submit supplementary identification issued to you in the common-law relationship surname to support the written request. If your passport is issued in a previous married name, you should apply for a new passport. Last Reviewed: August 2012
