Washington Satisfaction of Mortgage is a document used in the state of Washington to prove that a debt secured by a mortgage has been fully satisfied. It is typically recorded in the county where the mortgaged property is located. This document is usually provided by the lender after the loan has been paid in full, and it releases the borrower from any further liability on the loan. In some cases, a Washington Satisfaction of Mortgage may also be issued by a third party. There are two types of Washington Satisfaction of Mortgage documents: one for residential mortgages and one for commercial mortgages. The residential version is used when the mortgaged property is a single-family home. The commercial version is used for business properties, such as office buildings and warehouses. In both cases, the document must be signed by the borrower and lender, and it must be recorded with the county clerk's office in order to be legally binding.
