The three deadlines
A Section 138 prosecution only becomes available if the sequence is followed exactly.
Which court, and what the complaint must prove
Jurisdiction ordinarily lies where the payee’s bank branch is situated, which for Chennai payees usually means a Chennai Magistrate. The complaint must establish a legally enforceable debt, issue of the cheque towards that debt, dishonour, notice, and non-payment.
The statutory presumption works in the payee’s favour: once issue and signature are admitted, the law presumes the cheque was for a debt. The burden then shifts to the drawer to rebut it.
Defending a Section 138 complaint
Defences that work are factual and evidenced: that the cheque was given as security and not for a debt, that no legally enforceable liability existed, that the signature is not the drawer’s, that the notice was never served, or that the amount was in fact paid.
Defences that rarely work include a bare denial or an assertion of financial difficulty. Where the debt is genuine, the more productive conversation is usually about settling, because a compounded settlement ends the prosecution and avoids a conviction.
