Forgot your old bank signature? Start with verification
You visit the bank after years, sign a withdrawal request and hear that your signature does not match. Age, illness and changes in handwriting can cause this problem. The useful next step is to request the bank’s identity-verification and specimen-update procedure, especially if you cannot reproduce the old signature at all.
A mismatch does not by itself mean that your deposit has been confiscated. However, the bank may withhold action on a signed instruction until verification is complete. First establish whether the signature is the only problem or whether the account also has a separate restriction.
Separate a signature issue from KYC or account restrictions
Ask the counter staff three questions: which instruction was declined, whether the account has any other restriction, and which signature-change process applies to your account type. Request the form and a written checklist rather than making repeated attempts at the old signature.
An account unused for many years may also require KYC updating or reactivation. Updating a specimen does not automatically remove a freeze or resolve other account-status issues. List each outstanding requirement separately.
Five steps when you cannot reproduce the old signature
- Explain the exact difficulty. State that you are the account holder and cannot reproduce the old specimen. Ask for verification and recording of your current signature.
- Get the correct form. Confirm that it covers your deposit account, not a demat or shareholder service.
- Prepare accepted identification. Bring the originals and copies requested by the bank, available account details and customer ID.
- Request the alternative verification route. Ask about in-person checks, signing before an officer, acceptable attestation or other due diligence. Availability depends on the bank and case.
- Keep acknowledgement and completion evidence. Ask for a reference, expected processing time and the accounts affected.
If a form asks for the old specimen and you genuinely cannot provide it, ask how to record that inability. Do not fill the field with repeated guesses or a relative’s imitation.
Is a notarised affidavit always compulsory?
No universal affidavit rule should be assumed. If your bank requests one, obtain its exact format, applicable stamp-paper requirement and accepted attesting authority first. An affidavit is supporting evidence, not a guarantee that every identity check or withdrawal restriction disappears.
There are different published routes: HDFC offers an eligible-customer digital signature-update journey involving video KYC; ICICI’s RFC account FAQ describes evidence or attestation options for that product. These examples show why the account and bank matter.
Keep signature change distinct from changing your name, adding a joint holder or changing operating instructions. Apply only for the service you need and understand any declaration before signing it.
Urgent withdrawal and customers unable to sign
If money is urgently needed for treatment or essential expenses, tell the branch manager in writing and ask what authorised payment route may be available after verification. If your own ATM, UPI or internet-banking service is already legitimately active, ask whether it remains usable. These channels must not be used to evade a separate account freeze.
Physical inability to sign is different from forgetting a specimen. Ask about the bank’s assisted-operation process using a thumb impression or mark, witnessed identification, and any applicable doorstep service. Obtain the current requirements rather than assuming every elderly customer must use the same route.
A family member should not forge the customer’s signature or apply their thumb impression without consent. Any representation or assistance must follow the bank’s authorised arrangement.
A short application and an escalation path
To the Branch Manager, [bank/branch]. Subject: Request to update specimen signature where the old signature cannot be reproduced. My account/customer ID is [details]. My signature has changed over time and I cannot reproduce the old specimen reliably. Please explain the applicable identity checks, signature-update form, supporting documents and alternative verification route. Please acknowledge this request and provide any deficiencies in writing. Enclosures: [actual documents]. Name, contact, date and signature as advised by the bank.
This is a covering request, not a replacement for the prescribed form. If the branch refuses to accept it or gives conflicting instructions, submit a factual complaint through the bank’s official grievance channel. Include acknowledgement references, dates, the response and the specific solution sought.
If unresolved, consider RBI CMS after checking the current Ombudsman admissibility and filing deadlines. Do not copy an old time limit from an outdated article.
Advice: review outstanding cheques after the update
Submission and activation are separate stages. Obtain confirmation that the new specimen is recorded before relying on it. Tell the bank about outstanding cheques, post-dated cheques and pending signed instructions; ask how to avoid a return caused by the change.
Choose a signature you can repeat comfortably. Do not publish specimen images, PAN copies or account details online to seek help. Use official support and reject callers requesting OTPs or remote access for a supposed signature update.

Frequently asked questions
Will the bank show me the old specimen?
You can ask, but do not assume disclosure or a copy is mandatory. Request the alternative verification process if you cannot reproduce it.
Will an affidavit guarantee immediate withdrawal?
No. Verification, update completion and any other restrictions still matter.
Can I update the signature online?
Some banks offer a digital route for eligible customers. Use the bank’s official channel and check eligibility.
How many days does it take?
Do not assume one deadline for all banks. Ask for the service reference, expected time and completion status.
Can a relative sign for me?
They must not imitate your signature. Ask the bank about a valid representation or assisted-operation process.
