Ind. Code § 32-29-1-7

Sec. 7. If a mortgage has been paid and satisfied by the mortgagor, the mortgagor may take a certificate of satisfaction, duly acknowledged by the mortgagee or the mortgagee's lawful agent, as required for the acknowledgment of conveyances to entitle them to be recorded. The certificate and acknowledgment shall be recorded by the recorder in whose office the mortgage is recorded, with a reference to the location of the record of the mortgage. The recorded certificate discharges and releases the mortgagor from the mortgage (or portion of the mortgage as indicated in a partial satisfaction), and bars all suits and actions on the mortgage.
