Changing your name in Texas requires the same information and process as changing your name in any state. This is an easy process that takes roughly 15 minutes at a Social Security office. You can change your name after a divorce, after a marriage, or if you have a court order to change your last name.
Gather proof of identity. You must provide a U.S. passport, driver's license, or State issued non-driver identification card. The driver's license and state issued identification card can be from any state.
Gather proof of citizenship. You must provide a U.S. birth certificate, U.S. consular report of birth, U.S. passport, Certificate of Naturalization or Certificate of Citizenship.
Gather proof of a legal name change. You must provide a marriage certificate, divorce decree, court order for name change, or a Certificate of Naturalization showing a new name.
Fill out SS-5 form. You can get this form online at the Social Security website (see Resources) or fill out the form at the nearest Social Security Office.
Go to the nearest Social Security office (see Resources) with all your documents. You can apply for a new card at the office and you will receive your new card within two to three weeks.
