Dear Sir / Madam,
I hold account no. [account no.] with your branch. I wish to change the specimen signature recorded against it.
My old and new signatures are attested below, and I am attaching identity proof as required. Please update the signature on record and honour instruments carrying the new signature from the date of the change.
I confirm that instruments already issued under the old signature and presented before that date may be honoured in the usual way.
What is a Signature Change Request Letter?
A signature change request asks an institution to replace the specimen signature it holds against your account with the way you sign now. It matters because the specimen is what every future instruction is checked against: if your handwriting has drifted, cheques come back marked signature differs, withdrawal slips are refused at the counter, and forms you have already posted are returned weeks later without being processed.
Account holders send one when the signature they gave at account opening no longer resembles what they write, after a marriage or a legal name change, after an illness or injury that affects the hand, or when a signature was always inconsistent and keeps being queried. Businesses send one when an authorised signatory's specimen needs updating on a mandate. The same change usually has to be made separately with every bank, insurer, fund house, depository and pension office you deal with.
Procedure is set by the institution rather than by law, and it is usually stricter than people expect. Most banks require you to attend a branch with photo identification so the old signature can be verified in person; some accept a request attested by another branch, a notary or a manager where you live abroad. Company and trust signatory changes normally need a supporting board or committee resolution, and in some countries a filing with the registrar as well. Ask for the institution's current procedure before you write anything.
Changing the specimen does not change anything else on the account. It is not a name change, and if your name has also changed you need that separately with its own proof. It does not add or remove an authorised signatory — that is a mandate variation. It gives nobody authority to sign on your behalf, so it is not a substitute for a power of attorney, which is a matter for a qualified adviser. It also does not deal with cheques you have already issued under the old signature; raise those with the bank as a separate question.

How to write a Signature Change Request Letter
List every record you want updated
Quote the account numbers, the locker number, fixed deposit receipts, demat or folio numbers and any loan account held with the same institution. Banks update the signature against the records you name, not against your whole relationship, and the account you forget is the one you will use next month.
Show the old and new signature together
Provide a box for the existing signature and a box for the new one, and sign each once, cleanly. Sign the new specimen exactly as you intend to sign every cheque and form from now on — not a careful, slow version you will never reproduce at a counter. A specimen you cannot repeat causes the same problem you are trying to fix.
Give the reason in a single line
Institutions record a reason, and a plain one helps: the existing signature is inconsistent and instruments are being returned, the signature has changed following surgery, or the name and signature have both changed following marriage. Where the reason is medical and the change is significant, expect the bank to ask for additional verification.
Attend with identification and be ready to verify
Take current photo identification, address proof if the institution asks for it, and the cheque book or passbook for the account. Where the old signature can no longer be produced at all, ask in advance what the alternative verification is — some institutions accept a thumb impression with witnesses, others require a specific procedure. Do not turn up assuming a letter alone will do.
Confirm the effective date and update everything downstream
Ask when the new specimen takes effect, get an acknowledgement, and ask directly what happens to cheques already in circulation signed the old way. Then repeat the change with your other institutions and re-sign any standing form — mandates, nomination forms, insurance proposals — that will be checked against a specimen later.
Common mistakes
- Registering a careful specimen you cannot reproduce at speed, so instruments keep being returned for mismatch after the change.
- Assuming one bank's update flows through to your insurer, fund house and depository, then finding claim and redemption forms rejected months later.
- Not asking what happens to cheques already issued under the old signature, which can lead to them being returned unpaid with charges and, in some jurisdictions, consequences under cheque dishonour law.
- Posting the request where the institution requires in-person verification, so it is filed without action and nobody tells you.
- Sending a company signatory change without the supporting resolution, which means the mandate stays as it was and payments keep failing.
Frequently asked questions
How do I change my signature at the bank?
Ask the branch for its signature change form, complete it with the old and new specimen, and take photo identification with you. Most banks verify in person because the whole point of the exercise is to confirm the person changing the specimen is the account holder. Procedures differ between institutions, so ask yours rather than assuming another bank's process applies.
Do I have to go to the branch in person?
Usually yes, at least once. Some institutions accept a request attested by a notary, a consular officer or another bank where you live overseas, and a few allow it through a verified digital channel. Where the account has a locker or a large balance, expect stricter verification rather than looser. Ask what alternatives exist before travelling.
Will my old cheques still be honoured?
Ask the bank, because the answer depends on its policy and on when the cheque is presented. Cheques already handed to other people are the practical risk: they carry the old signature and may be presented after the specimen has changed. If any are outstanding, tell the bank about them at the time you make the change rather than afterwards.
Can I change my signature and my name at the same time?
You can submit both together, but they are separate updates with separate evidence. The name change needs its documentary proof — a marriage certificate, deed poll, gazette notification or court order, depending on the country — while the signature change needs verification of identity. Doing them in one visit is efficient; assuming one covers the other is not.
What if I can no longer sign because of illness or injury?
Institutions have procedures for this, including thumb impressions witnessed by an official and, in more serious cases, arrangements involving a legally appointed representative. The bank will normally want medical confirmation and may arrange a visit. Anything involving a power of attorney or a court-appointed deputy is not a form-filling exercise — take that to a qualified adviser.
