Ind. Code § 26-1-3.1-604
(a) A person entitled to enforce an instrument, with or without consideration, may discharge the obligation of a party to pay the instrument:
(2) by agreeing not to sue or otherwise renouncing rights against the party by a signed record.
The obligation of a party to pay a check is not discharged solely by destruction of the check in connection with a process in which information is extracted from the check and an image of the check is made and, subsequently, the information and image are transmitted for payment.
