A registered voter may transfer his or her registration to another county by submitting a new voter registration application, or returning a signed confirmation notice that provides the new address.

The county auditor shall expedite the mailing of a confirmation notice to complete the county-to-county transfer.

The minimum information necessary to complete the transfer to the new county is:

(1) Name;

(2) Residential address;

(3) A signature on the oath in RCW 29A.08.230; and

(4) Either date of birth or voter ID number. The new county may request additional information to confirm that the registration application is a transfer.

When a voter requests to transfer after ballots have been mailed, the county auditor shall verify that a ballot has not been accepted for that voter. If a ballot has not been accepted, complete the transfer and issue the voter a current ballot.
