37 Tex. Admin. Code § 15.23
The applicant's full name is required on all applications for a driver license or identification certificate. No name will be used that has not been documented. This section is applicable to male and female applicants.
(1) An applicant may choose to use any birth surname, adopt the surname of his or her spouse, adopt the surname of a previous spouse, or adopt a hyphenated version of his or her surname and a spouse's surname. If a married applicant elects not to adopt a spouse's surname, the name will be listed as if unmarried on the application. If an applicant elects to adopt a spouse's surname, the application should list married name, first name, and middle name, or the applicant's birth surname may be used in lieu of middle name at the option of the applicant. An applicant with multiple surnames may choose the surname that is used. An applicant with a hyphenated surname may choose to use only one of the names as a surname. The first name of the applicant must be used as the first name on the application and on the transaction card, even if the applicant normally uses a middle name as the given name. Middle names will not be substituted for first names.
