There is no Texas law about changing your name after an informal (common law) marriage. To change your name on a Texas driver's license or ID, you'll need to provide a marriage license or a marriage verification letter from the Texas Department of State Health Services (DSHS).
How long will the entire application for change of name take? Name change actions can take anywhere from a day to six (6) months (sometimes even longer). The time it takes for such action to be ordered/decreed varies not only from county to county, but sometimes from courthouse to courthouse as well.
