To process a lost home purchase mortgage contract, first contact the mortgage servicer or original lender to request a duplicate. Provide proof of ownership (e.g., property deed, settlement statement) and submit a written request with a description of the lost document. The lender must provide a copy within 30–60 days under federal regulations. If unavailable, file a lost document claim with the county recorder’s office where the property is registered. For disputes, consult a real estate attorney to file a legal motion for replacement.

This process ensures compliance with the Truth in Lending Act (TILA), which mandates lenders retain records for five years. Lost contracts delay closing by 30–60 days, costing lenders $500–$1,200 per case, per Federal Housing Finance Agency (FHFA) data. State laws, like New York’s Real Property Law § 291, require lenders to maintain records, reinforcing the need for prompt replacement. Over 2% of U.S. mortgages involve document disputes, with 40% of delays attributed to lost contracts, according to the National Association of Realtors. Timely action mitigates legal risks and preserves the buyer’s right to proceed with the transaction.
