(B) A qualified elector who has moved from an address in one precinct to an address in another precinct within the same county, or has moved to another county within the thirty-day period before an election, and who has failed to notify the county board of voter registration and elections of the change of address before the date of an election, at the option of the elector:
(1) must be permitted to correct the voting records and vote provisional ballots containing only the races for federal, statewide, countywide, and municipalwide offices pursuant to the provisions of § 7-13-830 at the elector’s former polling place, upon oral or written affirmation by the elector of the new address before an election official at that polling place; or
(2) must be permitted to correct the voting records and vote at a central location located at the main office of the county board of voter registration and elections in his new county of residence where a list of eligible voters is maintained, upon written affirmation by the elector of the new address on a standard form provided at the central location.
(C) If the registration records indicate inaccurately that a qualified elector has moved from an address in the precinct, the elector shall be permitted to vote at that polling place, upon oral or written affirmation by the elector before an election official at that polling place that the qualified elector continues to reside at his address.
(D) For voting purposes, in the case of a change of address of a qualified elector to another address within the same county, the county board of voter registration and elections shall correct the voting registration list accordingly, and the elector’s name may not be removed from the official list of eligible voters except as provided in § 7-5-330(F).
(E) At least one member of the county board of voter registration and elections, the clerk, or deputy registrar must be present in the board’s office at all hours during which the polls are open on every election day for the purpose of carrying out the provisions of this section.
