Washington Partial Release of Mortgage is a legal document used in the state of Washington that releases a portion of a mortgaged property from the existing lien. When a Washington Partial Release of Mortgage is executed, the mortgage is “partially released” from the existing lien, allowing the mortgagor to transfer ownership of a portion of the property to another party. There are two types of Washington Partial Release of Mortgage: the Partial Release of Deed of Trust and the Partial Release of Mortgage. The Partial Release of Deed of Trust is used when the mortgagee is a trust company, and the Partial Release of Mortgage is used when the mortgagee is an individual. Both documents must be recorded with the county in which the property is located in order to be valid.
