Negotiable Instruments Law
Section 70. Effect of want of demand on principal debtor.- Presentment for payment is not necessary in order to charge the person primarily liable on the instrument; but if the instrument is, by its terms, payable at a special place, and he is able and willing to pay it there at maturity, such ability and willingness are equivalent to a tender of payment upon his part. But, except as herein otherwise provided, presentment for payment is necessary in order to charge the drawer and indorsers.
