(a) Same county.--

(1) A registered elector who has moved from an address in the county covered by a polling place to an address covered by the same polling place shall, notwithstanding failure to notify the commission prior to the date of an election, be permitted to vote in that polling place upon written affirmation by the elector of the change of address before an election official at that polling place.

(2) A registered elector who has moved from one address in the county to another address in the same county covered by a different polling place and who has failed to notify the commission of the change of address prior to the date of an election shall be permitted to correct the voting records and vote at the elector's former polling place upon written affirmation by the elector of the new address before an election official at the former polling place.

(b) Different county.--A registered elector who has moved from one county to another county and who has failed to notify the commission of the change of address prior to the date of the election shall be permitted to correct the voting records and vote at the elector's former polling place upon written affirmation by the elector of the new address before an election official at the former polling place. Upon receipt of the written affirmation, the commission shall follow the procedures in this part for change of address to a new county and shall update information contained in its registration records.
