If a cheque bounces and the payer makes a partial payment, but then fails to pay the remainder, you may still have legal recourse even if the initial deadline for a Section 138 complaint has passed. While a Section 138 case might be time-barred, a summary suit is often the quickest and most effective way to recover the outstanding amount, especially with a cheque in hand and acknowledgment of the debt. It's advisable to consult an experienced lawyer to explore this option, as there are no monetary limits for filing a summary suit.
