Washington Partial Release of Mortgage (also known as a 'deed of reconveyance') is a legal document that releases a portion of the mortgage debt that is secured by a piece of real property in the state of Washington. It is commonly used when a borrower has paid off part of their mortgage loan, such as when a borrower refinances their mortgage. The document must be signed by both the borrower and the lender, and recorded with the county recorder's office. There are two types of Washington Partial Release of Mortgage: Partial Release of Mortgage for Refinancing and Partial Release of Mortgage for Partial Payment. The Partial Release of Mortgage for Refinancing is used when a borrower is refinancing their mortgage loan, while the Partial Release of Mortgage for Partial Payment is used when a borrower is making a partial payment on their mortgage loan.
