Altered Cheque

Altered Cheque — Meaning, Definition & Full Explanation

An altered cheque is a negotiable instrument whose material terms—such as the payee name, amount, or date—have been deliberately changed to commit fraud. The alteration is made after the cheque has been issued by the drawer, and it becomes a criminal offense under Indian law if the altered cheque is presented for payment or negotiation.

What is Altered Cheque?

An altered cheque represents one of the most prevalent forms of cheque fraud in banking. Unlike a forged cheque (where the signature is imitated) or a completely falsified cheque (which is entirely fake), an altered cheque begins as a legitimate instrument that is then modified dishonestly. The person committing the fraud changes specific details on an existing cheque to extract money fraudulently.

The most common alterations involve changing the numerical or written amount, the payee's name, the date, or the drawer's signature. For instance, a cheque issued for ₹10,000 may be altered to ₹1,00,000, or a cheque payable to "Rajesh Kumar" may be changed to "Ramesh Kumar" to divert funds. Alteration of the amount is typically easier to execute than changing the payee name, which requires matching handwriting or forging signatures. Banks and drawers must remain vigilant because altered cheques can be cashed, deposited into accounts, or used to clear transactions before detection occurs. The liability and responsibility for spotting altered cheques rests primarily with the paying bank, which must exercise reasonable care during the verification process.

How Altered Cheque Works

The mechanism of an altered cheque fraud typically unfolds in the following sequence:

1. Initial issuance: A drawer (account holder) issues a legitimate cheque to a payee for a genuine transaction, specifying a specific amount and payee name.

2. Interception and alteration: The cheque is intercepted or obtained by a fraudster who possesses the cheque before it reaches the intended payee. The fraudster then makes unauthorized changes to critical fields using erasure, overwriting, or chemical agents.

3. Amount manipulation: The most common alteration involves increasing the cheque amount. For example, ₹5,000 becomes ₹50,000 by adding a zero, or the written amount is erased and rewritten for a larger sum.

4. Payee name change: The fraudster alters the payee name to their own name or an accomplice's name, potentially forging the signature to match the new payee identity.

5. Presentation for payment: The altered cheque is presented to the paying bank (the drawer's bank) for encashment or deposited into another bank for credit.

6. Clearing and settlement: If the paying bank fails to detect the alteration during verification, the cheque is cleared, and funds are transferred or withdrawn before the fraud is discovered.

The paying bank is responsible for verifying signatures, comparing the cheque with the drawer's specimen signature, and detecting physical signs of tampering such as erasures, chemical bleaching, or overwriting. Banks use technology including magnetic ink character recognition (MICR) scanning and document imaging to identify suspicious alterations.

Altered Cheque in Indian Banking

Under Indian law, presenting or using an altered cheque is a serious criminal offense governed by the Negotiable Instruments (NI) Act, 1881. Section 138 of the Act specifically addresses dishonored cheques, which includes cheques that are altered and subsequently rejected by the paying bank due to discrepancies in material terms.

The Reserve Bank of India (RBI) has issued comprehensive guidelines on cheque fraud prevention and loss mitigation. Banks are mandated to exercise "due diligence" while verifying cheques, comparing signatures meticulously with specimen records, and flagging documents showing signs of physical tampering. RBI circular guidelines require banks to maintain robust internal controls and staff training to identify altered cheques before clearing.

If a cheque is altered and dishonored, the drawer can initiate legal action under Section 138 of the NI Act, which prescribes punishment of imprisonment up to one year, or a fine up to double the cheque amount, or both. However, the drawer must prove they did not authorize the alteration.

For banking professionals, knowledge of altered cheques is essential content in the JAIIB (Junior Associate, Indian Institute of Bankers) syllabus, particularly in modules on negotiable instruments and cheque clearing. The topic also appears in CAIIB examinations focused on audit, compliance, and risk management.

Many Indian banks, including State Bank of India (SBI), HDFC Bank, and ICICI Bank, have implemented automated cheque processing systems and Artificial Intelligence-based fraud detection to minimize altered cheque incidents. The National Payments Corporation of India (NPCI) has set standards for cheque clearing that emphasize early detection of discrepancies.

Practical Example

Priya, an accountant at XYZ Manufacturing Ltd in Mumbai, issues a cheque for ₹25,000 to "M/s Supplier Solutions" on 10th January 2025. The cheque is mailed to the supplier's address but is intercepted by Ankit, a temporary office worker who had recently been terminated.

Ankit carefully erases the amount "25,000" and overwrites it as "2,50,000" using matching blue ink. He also changes the payee name from "M/s Supplier Solutions" to "M/s Supply Solutions" to avoid immediate detection. He deposits the altered cheque into his newly opened account at a private bank.

When the cheque reaches XYZ Manufacturing's bank (the paying bank) for clearing, a junior teller notices the erasure marks around the amount field but fails to compare the signature carefully. The cheque is cleared within 24 hours, and ₹2,50,000 is credited to Ankit's account. By the time XYZ Manufacturing's bank statement arrives, Ankit has already withdrawn ₹2,00,000 and closed the account.

XYZ Manufacturing discovers the fraud when reconciling its bank statements. The paying bank is held liable for not exercising due diligence, and Ankit faces criminal charges under Section 138 of the NI Act. The incident highlights the critical importance of banker's verification responsibilities.

Altered Cheque vs Forged Cheque

Aspect	Altered Cheque	Forged Cheque
Basis	Legitimate cheque modified after issuance	Completely counterfeit instrument created without authorization
Signature	May retain original or be imitated	Signature is entirely fake or imitated
Detection	Physical signs like erasures, overwrites, or chemical marks	Signature mismatch with specimen; no legitimate issuance record
Liability	Paying bank liable if due diligence fails	Drawer typically not liable; paying bank bears loss

An altered cheque begins as a genuine document and is tampered with, whereas a forged cheque is fabricated entirely without the drawer's involvement. Both are fraud, but the paying bank's verification procedures differ slightly: for altered cheques, banks must scrutinize physical document integrity; for forged cheques, signature matching is paramount.

Key Takeaways

• An altered cheque is a genuine negotiable instrument whose material terms (amount, payee name, date, or signature) are fraudulently modified to commit theft.
• The most commonly altered field is the cheque amount, as it requires fewer changes than altering the payee name convincingly.
• Under Section 138 of the Negotiable Instruments Act, 1881, presenting an altered cheque invokes criminal liability with imprisonment up to one year or fine up to double the cheque amount.
• The paying bank is responsible for detecting altered cheques through signature verification, physical document inspection, and examination of MICR details.
• RBI guidelines mandate banks to implement due diligence protocols, staff training, and automated fraud detection systems to prevent altered cheque losses.
• Banks can identify alterations by observing erasure marks, overwriting, chemical bleaching, inconsistent pen pressure, and signature mismatches.
• The drawer of the original cheque is not liable if the paying bank fails to detect the alteration and clears a fraudulent cheque.
• Modern banking systems use image-based clearing and AI-driven anomaly detection to reduce altered cheque incidents across Indian banks.

Frequently Asked Questions

Q: Who is liable for loss caused by an altered cheque—the drawer or the bank?

A: The paying bank bears primary liability if it fails to exercise reasonable care and due diligence while verifying the cheque. The bank must compare signatures, inspect physical signs of tampering, and verify the amount's legality. However, if the drawer was negligent in safeguarding the cheque book or authorized the alteration implicitly, shared liability may apply.
