A Washington Release of Lien is a document used to release a lien or security interest in the state of Washington. It is typically used when a secured party has been paid in full and wishes to release their claim on a borrower's property. There are two types of Washington Releases of Lien: Waiver of Lien and Certificate of Release of Lien. A Waiver of Lien is used to waive a lien, while a Certificate of Release of Lien is used to release a lien. Both documents must be signed by the secured party, and the Certificate of Release must be notarized. The documents must also include the borrower's name, the date of the lien, and the amount paid. The Waiver of Lien and Certificate of Release of Lien must be filed with the appropriate County Clerk's Office in Washington in order to be valid.
