HOW TO CHANGE YOUR NAME IN TEXAS AFTER DIVORCE
There is no such default procedure in Texas that automatically changes your name after a divorce is finalized unless otherwise indicated in a divorce decree. It means that changing a Legal Name procedures must be either claimed separately or carried out as one of the divorce steps.
In case of changing last name after divorce the willing spouse has to complete at court Order Restoring Name Used Before Marriage where the person indicates the desire to adopt a maiden name or have the new one and also specifies the desired one.
If the Order wasn’t done on time and the divorce is already over one may file the Petition to change the name of an adult and mention marriage dissolution as a reason.
