§ La. R.S. 18:111(untitled)

Change of name or signature; married persons
A. In order to remain a legal registrant, a person who changes his name by virtue of a judgment of
court shall produce in the presence of or, if required, file with the registrar or any person authorized to accept
voter registration applications a certified copy of the judgment, his Louisiana driver's license number,
Louisiana special identification card number, or social security number, or his attestation setting forth the
pertinent facts containing the change of name.
B. A married person may be registered using the surname of either or both spouses as a surname,
or in a hyphenated combination thereof. If divorced, widowed, or remarried, the applicant may be registered
using his surname, in the surname of the deceased or former or present spouse, or in a hyphenated
combination thereof. A person who changes his name by virtue of marriage shall submit a voter registration
application to the registrar or other person authorized to accept voter registration applications that contains
the applicant's social security number, valid Louisiana driver's license number or Louisiana special
identification card number, or attestation setting forth the name under which the applicant desires to be
registered as allowed by this Section.
C. If a registered voter, subsequent to his registration, is no longer capable of signing his name
without using a mark, he shall file an attestation with the registrar of voters attesting to that fact and stating
the reason for such a change in signature.
