Effect of want of demand on principal debtor.
Section 70
SEC. 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.
