Assignment and Release Records
Assignment and release records show what happens to a mortgage after it is recorded. An assignment documents the transfer of a mortgage from one lender or loan holder to another, while a release shows that the loan was paid off and the lien cleared from the property.
Mercer County has a combined 214,641 assignment and release records on file. They include 43,239 assignment documents recorded from April 27, 2000, through August 25, 2025, and 170,818 release documents recorded from January 7, 2005, through August 25, 2025, along with 584 other documents.
For property research, these records help buyers, owners and title researchers see who has held a mortgage over time, confirm that earlier loans were satisfied, and spot liens that may still need to be cleared before a sale or refinance. The long date ranges also make it easier to follow a property's financing history across multiple owners and lenders, and to focus on documents recorded during a particular period.
