When a write-in candidate files a declaration in a multicounty jurisdiction, the filing officer shall notify the affected counties. The filing officer must combine the write-in totals from all affected counties to determine if the total write-in votes must be tallied for individual candidates as per chapter 29A.60 RCW. If votes must be tallied, the officer must immediately notify the affected counties.

With the exception of certificates of election issued in accordance with RCW 29A.52.360 and 29A.52.370, the filing officer must collect and combine the certified results from the county canvassing boards in order to issue a certificate of election for candidates in multicounty jurisdictions.
