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 or his affidavit setting forth the pertinent facts containing the change of name.

If divorced, widowed, or remarried, she may be registered in her maiden name, in the surname of her deceased or former or present husband, or in a hyphenated combination thereof. A change of name allowed by this Subsection shall be made by producing in the presence of the registrar or other person authorized to accept voter registration applications her affidavit stating the name under which she 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 affidavit, meeting the requirements of R.S. 18:200, with the registrar of voters attesting to that fact and stating the reason for such a change in signature.
