Assignment and Release Records
Assignment and release records follow a mortgage after it is recorded. An assignment shows that a loan was transferred from one lender or holder to another, and a release shows that the loan was satisfied and the lien removed from the property.
Washington County has 639,737 assignment and release records available for research. They include 62,015 assignment documents and 576,871 release documents, along with 851 other documents. Assignments were recorded from November 27, 2002, to September 4, 2025, and releases from November 10, 2003, to September 4, 2025.
These records help researchers see who currently holds a mortgage, follow a loan as it moved between lenders, and confirm that earlier loans were paid off. They are especially useful before a purchase or refinance, when you need to know whether a lien from a past loan could still be open. The long date range allows research across more than two decades of activity.
