Cheque Returned for Signature Mismatch? Check This First

"My cheque came back with 'drawer's signature differs', but I signed it myself." If this is you, the fix is: before you write a new cheque, find out which signature the bank actually holds and why the image failed to match, then reissue only once that cause is fixed, or pay electronically. Reissuing a second cheque with the same problem means another return, another charge and, if the payee is pressing, a stronger case against you.

This guide is for the person who wrote the cheque. If you received a returned cheque, see our main guide on what to do when a cheque bounces.

What the return reason actually means

Banks use standard return reason codes on the return memo. The signature group, as listed on SBI's customer page and in RBI's model list, is:

Code numbering can vary slightly between banks, so read the words on the memo, not just the number. Code 85 ("alterations other than date field") is separate: under the Cheque Truncation System (CTS), corrections other than the date are not accepted at all.

Why signatures fail in CTS clearing

Under CTS, the paying bank checks an image of the cheque, not the paper. Since 4 October 2025 cheques are cleared continuously during the day under Phase 1 of RBI's continuous clearing; Phase 2 was postponed in December 2025 until further notice. Faster clearing means a return can reach the payee the same day. Common causes:

• The specimen is old. It was taken at account opening, maybe 15 years ago, and your signature has drifted.
• You have more than one signature style. Full signature on the account form, short version on cheques.
• Scan problems. Light ink, signature running over printed lines or the MICR band, or a fold through the signature.
• Mandate problems. A joint account opened as "jointly" needs both signatures; a company or partnership needs the authorised combination.
• Changed signatory not updated. A new director or partner signs before the bank has recorded their authority.

What to check before reissuing

1. Read the return memo and note the exact reason, date and charge.
2. Ask the branch to show you the specimen on record (many banks will let you view it at the branch, not over the phone).
3. Compare honestly. If your current signature is different, request a specimen signature update. Most banks need a form, photo ID and an in-person visit.
4. Check the account mandate. For joint, HUF, company or trust accounts, confirm who must sign and in what combination.
5. Ask when the new specimen is active. Signature records used in clearing may take a few days to update.
6. Check the cheque itself. Use dark ink, sign within the signature space, do not overwrite, and do not let the signature touch the MICR band.
7. Register Positive Pay for high-value cheques. RBI's Positive Pay system lets you confirm cheque details in advance for cheques of ₹50,000 and above; banks may make it mandatory for ₹5 lakh and above. It does not cure a signature mismatch, but it avoids a second reason for return.
8. Recover or cancel the old cheque. Ask the payee to return it so it cannot be presented again.
9. Consider paying electronically. NEFT, RTGS or IMPS avoids the signature check entirely; see NEFT vs RTGS vs IMPS.

The legal side: why speed matters

A signature mismatch is not just a technical hiccup. In Laxmi Dyechem v. State of Gujarat (2012), the Supreme Court held that a cheque dishonoured because the signature does not match can attract Section 138 of the Negotiable Instruments Act, 1881, provided the other conditions of that section are met. Courts look at the facts, including whether the mismatch was deliberate.

The timelines are the same as for any bounced cheque: the payee must send a written demand within 30 days of receiving the return memo, and you then have 15 days from receiving the notice to pay. Paying in that window ends the criminal exposure under Section 138. A cheque is valid for three months from its date, so the payee can also re-present your corrected cheque within that period.

Worked example: Neha's ₹48,000 cheque

Neha issues a cheque for ₹48,000 dated 1 October 2026 to her landlord. It is returned on 6 October with "12 – drawer's signature differs". The landlord receives the memo the same day.

Neha checks with the branch on 7 October and finds the specimen is from 2009. She updates it, then pays the rent by IMPS on 8 October and takes the original cheque back. The return charge debited from her account stays, because the mismatch was on her side.

If the branch had shown that her signature did match and the bank's system had failed, she could ask for the charge to be reversed. RBI's directions on cheque return charges say they should be levied only where the customer is at fault. Keeping a small buffer, for example in a sweep or short deposit you can check with our FD calculator, helps you pay electronically at once when a cheque problem appears.

Where to complain if the bank got it wrong

From 1 July 2026, new Ombudsman complaints fall under the Reserve Bank – Integrated Ombudsman Scheme, 2026. See bank not resolving your complaint.

Ready-to-copy complaint message

Subject: Cheque returned for signature mismatch – request for review – a/c [last 4 digits]

Dear Sir/Madam,

Cheque no. [number] dated [date] for ₹[amount], drawn on my account
[last 4 digits], was returned on [date] with reason "[reason/code]".
A return charge of ₹[amount] was debited on [date].

[Choose one:] The signature on the cheque matches my specimen on record /
I had submitted a specimen signature update on [date], acknowledgement
no. [ ], which was not applied.

Please review the return, share the reason in writing, reverse the
charge if the return was not due to my fault as per RBI directions, and
confirm the specimen currently on record.

What not to do

• Do not re-sign or overwrite the returned cheque. CTS rejects alterations other than the date.
• Do not issue a new cheque before checking the specimen. Two returns look worse than one.
• Do not ignore a demand notice. Pay within 15 days of receiving it, and get written acknowledgement.
• Do not share cheque book photos, OTPs or net banking details with callers claiming to "update your signature online". Signature updates are done at the branch.
• Do not keep unused cheques from an old signature style in circulation; cancel them if you have updated the specimen.

Key takeaways

• Return codes 10 to 17 are signature and mandate problems; read the exact wording on the memo.
• Check the specimen and mandate the bank holds before reissuing, and update it if your signature has changed.
• A signature mismatch return can still attract Section 138; pay within 15 days of a demand notice.
• Charges should apply only if you were at fault; ask for a reversal if the bank erred.
• When in doubt, pay by NEFT, RTGS or IMPS and recover the original cheque.
