Note: In Washington State, official public records are recorded with the County Auditor. In 1969, when King County adopted its home-rule charter, the office of County Auditor was abolished and the recording function was assigned to the King County Recorder's Office. Older documents may refer to the "King County Auditor" or show an Auditor's or recording number that has been stamped or marked. Questions regarding these documents should be directed to the Recorder's Office. The current King County "auditor's office" is responsible for other functions and does not record official public records.
