Verification of voter registration

(1) A clerk shall use the following procedures to determine whether a signer of a petition is a registered voter and to determine the address where the voter is registered to vote: (a) if a signer's name and address provided by the individual with the individual's petition signature exactly match a name and address shown on the official register and the signer's signature appears substantially similar to the signature on the statewide voter registration database, the clerk shall declare the signature valid for the district or jurisdiction in which the signer is registered to vote; (b) if there is no exact match of an address and a name, the clerk shall declare the signature valid for the district or jurisdiction in which the signer is registered to vote, if: (i) the address provided by the individual with the individual's petition signature matches the address of an individual on the official register with a substantially similar name; and (ii) the signer's signature appears substantially similar to the signature on the statewide voter registration database of the individual described in Subsection (1)(b)(i); (c) if there is no match of an address and a substantially similar name, the clerk shall declare the signature valid for the district or jurisdiction in which the signer is registered to vote if: (i) the birth date or age provided by the individual with the individual's petition signature matches the birth date or age of an individual on the official register with a substantially similar name; and (ii) the signer's signature appears substantially similar to the signature on the statewide voter registration database of the individual described in Subsection (1)(c)(i).
