37 Tex. Admin. Code § 15.23
The applicant's full name is required on all applications for driver's license and identification certificates.
(1) A married woman may choose the surname she wishes to use, either her maiden name or she may adopt the surname of her husband or the surname of a previous husband. If she elects not to adopt her husband's surname, she will simply list her name as if unmarried on the application. If she chooses to adopt her husband's surname, the application should list married name, first name, and middle name, or the maiden name may be used in lieu of middle name at the option of the applicant. A married woman's middle name may be used as her first name if desired. Example: Mary Ellen Smith marries Brown; she may list her name as Brown, Mary Ellen, or Brown, Mary Smith, or Brown, Ellen Smith. In all cases, three full names will be used, unless the applicant does not wish to use the maiden name.
