The Impact of Forgery on Negotiable Instruments: Legal Protections and Liabilities

A single forged signature on a cheque or bill of exchange can undo an entire chain of business transactions. Retail businesses run on credit instruments, trade bills, and cheques changing hands constantly, and the law needs a clear answer to a simple question: what happens when one of those signatures is fake? The Negotiable Instruments Act, 1881 takes a firm position on this, and understanding it protects you whether you are a trader accepting a cheque, a bank processing payment, or a student trying to make sense of commercial law.

What counts as a forged instrument 🔗

Forgery is not defined inside the Negotiable Instruments Act itself. Courts and practitioners borrow the definition from criminal law. Under the Bharatiya Nyaya Sanhita, 2023, forgery means making a false document or record with intent to deceive, cause damage, support a false claim, or induce someone to part with property. Applied to commerce, this covers two very different situations: someone fabricating an entire cheque or promissory note in another person’s name, and someone genuinely-issued instrument being altered or signed away using a fake signature at the point of transfer.

The second situation is what the law calls a forged indorsement. The instrument itself, say a cheque drawn by a company in favour of a supplier, is completely genuine. The forgery happens later, when someone signs the supplier’s name on the back to transfer it onward without the supplier’s knowledge or authority.

Forged instrument versus forged indorsement 🔗

Students often mix these two up, but the legal consequences differ. A forged instrument (where the maker’s or drawer’s own signature is fake) never had a genuine party bound to it at all. A forged indorsement, by contrast, affects only the chain of transfer that comes after a genuine instrument was created.

Why a forged indorsement transfers nothing 🔗

The core rule is straightforward: a signature that has been forged has no legal existence. Whoever held the instrument at the moment of forgery remains its rightful owner, no matter how many hands it passes through afterward. Every subsequent transferee, even one who pays full value and has no idea anything is wrong, ends up with no enforceable right to the instrument or its proceeds.

This is a deliberate policy choice. Ordinarily, a holder in due course who takes a negotiable instrument in good faith, for value, and before maturity gets better title than the person who transferred it to them, even if there was some defect earlier in the chain. Forgery is the one defect this protection does not cure. Since a forged signature legally does not exist, there is nothing for the “holder in due course” doctrine to operate on. The instrument simply never left the true owner’s hands in the eyes of the law.

What the true owner can do 🔗

Because ownership never actually shifts, the person whose signature was forged retains every right against the forger and against anyone who benefited from the fraud. This typically plays out as:

• Recovery of the instrument or its value: The true owner can demand the instrument back, or sue for the money if it has already been collected.
• Action against the forger: Civil recovery alongside criminal prosecution for forgery and cheating.
• Claim against a bank that wrongly paid out: If a bank collected or paid money on a forged indorsement without proper care, it may be liable to the true owner for conversion.

Where the acceptor and paying banker stand 🔗

Section 41 of the Act carves out a specific rule for a bill’s acceptor. Under the statutory text, an acceptor of a bill already bearing an indorsement is not excused from liability merely because that indorsement turns out to be forged, unless the acceptor actually knew or had reason to suspect the forgery when accepting. The idea is that acceptance creates an independent obligation; the acceptor cannot later hide behind someone else’s fraud to escape a debt they knowingly took on.

Cheques bring in a parallel but separate protection for the paying bank. Section 85(1) discharges the drawee bank when it pays a cheque, payable to order, that purports to be indorsed by or on behalf of the payee, so long as the payment is made in due course. This protects the bank’s position, but it does not validate the forged indorsement itself between the true owner and the fraudster. The Supreme Court clarified the limits of this protection in a landmark ruling: in Bank of Bihar v. Mahabir Lal, the Court held that a bank can only claim Section 85 protection when payment was actually made to the genuine holder or their authorised agent, in due course. Pay the wrong person, even by honest mistake, and that protection disappears.

Banks also cannot escape liability simply because a signature “looked convincing.” In a related case involving a forged drawer’s signature rather than a forged indorsement, courts confirmed that a bank has no authority to debit a customer’s account on a cheque bearing a forged signature, because the banker-customer relationship rests on a genuine mandate from the account holder. The banking sector treats forged-signature cheques and forged indorsements with equal seriousness because both break the chain of authority the entire payment system depends on.

The estoppel exception 🔗

There is one important limit to the “forgery transfers nothing” rule: estoppel. Section 115 of the Indian Evidence Act lays down the general principle that when a person’s own declaration, act, or omission intentionally causes another to believe something is true and to act on that belief, that person cannot later deny the truth of it in a legal proceeding. Applied to forgery, if the true owner’s own conduct created a reasonable impression that a signature was genuine or that someone had authority to sign on their behalf, they may be barred from later denying its validity against a party who relied on that impression in good faith.

When estoppel typically applies 🔗

• Habitual authorisation: A business owner who has repeatedly allowed an employee to sign cheques or bills on their behalf cannot easily claim forgery against a bank that reasonably relied on the established pattern.
• Delayed objection: Someone who discovers a forgery but stays silent for an unreasonably long time, letting others deal with the instrument as genuine, risks losing the right to raise forgery later.
• Negligent conduct: Careless handling of blank signed cheques or stationery that makes forgery easy can weigh against the true owner in court.

Estoppel is applied narrowly. The party invoking it must show genuine reliance, in good faith, and that the true owner’s own conduct (not just the forger’s cunning) created the false impression. Courts examine the facts closely rather than presuming estoppel from mere carelessness.

Why this still matters in digital-payment India 🔗

Cheque volumes have fallen, but the underlying principle now shapes India’s approach to digital fraud too. The Reserve Bank of India has steadily tightened rules on liability for fraudulent transactions in electronic banking, and under its most recent framework, customers bear zero liability where a fraudulent transaction results from the bank’s own negligence, and generally zero liability for third-party breaches reported within the prescribed window. The logic is the same one running through Sections 41 and 85 of the 1881 Act: loss from fraud should fall on whoever was negligent or best placed to prevent it, not automatically on the innocent party at the end of the chain.

Practical takeaways for businesses 🔗

• Verify indorsements carefully before accepting a negotiable instrument from someone other than the named payee.
• Secure blank cheques and signed stationery; a lost or stolen blank cheque is one of the easiest paths to forgery.
• Report suspected forgery immediately, both to your bank and, where relevant, to the police, since delay can weaken your legal position under estoppel.
• Maintain a clear, limited chain of authority for who can sign or indorse instruments on behalf of a business, and update it in writing whenever it changes.

What do you think? If a company’s own poor cheque-handling practices make forgery easy, should the law hold the company partly responsible even though it was technically the victim? And as India moves further toward digital and UPI-based payments, should the estoppel principles built for paper cheques apply just as strictly to authentication failures in electronic transactions?
