As previously stated, bills of exchange must be presented within a reasonable time after their issue or the drawer and indorsers will be discharged. The drawer of a check remains liable indefinitely, unless he is actually injured in some way by the holder's failure to present the check for payment. If the drawer suffers any loss he will be discharged to the extent of the loss. Thus, Brown gives Smith a check for $500. Smith does not present this within a reasonable time and Brown proves that he has been injured to the extent of $100. Then Brown will have to pay only $400 on the check. Suppose Smith does not present the check within a reasonable time and before he does present it the bank becomes insolvent. Then Brown is discharged, for if the maker of a check has funds in the bank on which it is drawn and the payee has sufficient time to present the check before the bank fails but does not do so, then the maker is not at fault and should not be made to suffer because of the payee's negligence.
