How can I change my legal name in San Francisco?
All name change requests not for the reason of marriage are conducted through the Superior Court of San Francisco, which is located at 400 McAllister Street, San Francisco, CA 94102.
You can file a petition for a name change and you will then be assigned a court hearing. During your court hearing, you will need to show justifiable reason for your desired name change. The process is complicated and there are several forms you need to fill out and procedures you need to follow, so check with the Superior Court of California website to verify that you are following the necessary steps.
If you are attempting to change the name of your child, you will need to inform the other parent so he or she may have the opportunity to contest the name change if desired.
