Search results are based on the indexing standards used at the time the document was recorded and indexing standards change over time. If you do not find a document on your first try, please adjust your search criteria. Results load one page at a time to ensure the fastest response time, so any sorting or filtering you do on one page of results need to be re-applied to each page of results you view.

- Search by Parcel: Enter the first ten digits in the "Parcel ID" field next to the "Starts With" field. Searching by parcel ID will only pull up recorded documents from 1997 to current. If you do not know the parcel ID, first visit the King County Assessor's Parcel Viewer to obtain the parcel ID by searching for the property address. Tutorial video
