U.S. Mortgage Assignment & Release Data for Loan Ownership and Lien Intelligence
What is Mortgage Assignment & Release Data?
Mortgage Assignment & Release Data from The Warren Group is a comprehensive dataset capturing the transfer of mortgage ownership (assignments) and the release of mortgage liens (releases) recorded in public records across the United States.
Assignment Data documents the transfer of ownership rights of a mortgage loan from one entity to another—including the parties involved, effective dates, and relevant terms. This is essential for tracking loan ownership across banks, credit unions, and mortgage-backed security issuers.
Release Data documents the satisfaction of a mortgage lien when a loan is paid off, refinanced, or otherwise satisfied—giving title companies, attorneys, and servicers a clear view of property lien status.
Core data categories include:
- Mortgage assignment records and ownership transfers
- Mortgage release / satisfaction records
- Original, assignor, and assignee details
- Lender names and loan information
- Property and borrower details
