3 GCA § 9127: Voter’s Change of Name.

If the full name or surname of any person desiring to vote has been legally changed since that person registered, that person shall report both his or her name as it was before the change, and his or her name as it is at the time of the election; provided, that the person presents to the precinct officials a legal document or other satisfactory written proof of the name change. The precinct board shall thereupon make the necessary adjustment in the register, indicating the reason for the change therein, and thereafter permit the person to vote.
