Many times when women and men divorce, the woman no longer wants to keep her ex-husband's last name. When the woman decides to drop her husband's name, she may want to assume her mother's maiden name--the name her mother had before she was married. She can change her last name to a mother's maiden name by filing the appropriate documents.
Go to your nearest Social Security Administration office and bring along a certified copy of your divorce decree, your birth certificate (to prove your identity) and your completed SS-5 application (the application to change your name on your Social Security Card).

Include a scanned copy of your driver's license so that they know what your new name is, or if you go there in person, simply show them your driver's license.
