Why signatures cause problems
RTAs compare the signature on a transfer, demat or service request with the specimen signature on file. After many years, signatures change — and in joint holdings a deceased holder's signature can never be matched.
SEBI's KYC framework for physical holders includes a specimen signature and a bank's confirmation of the signature, for which standard forms exist (for example ISR-1 and ISR-2). The exact documents depend on the RTA and the type of request.

Common problems we see
Objection on a demat request

How the process generally works
The exact steps depend on the company, the type of holding and the facts of your case. This is a general outline.
- 1
Obtain the RTA's current forms
Download from the RTA or company website.
- 2
Sign and get bank confirmation
As the form requires.
- 3
Submit with identity and KYC proof
Self-attested as instructed.
- 4
Confirm update
Ask the RTA for written confirmation of the updated record.
How IEPF Assist can help
- Explaining which form and attestation applies
- Reviewing documents before submission
- Following up on the update
We are an independent consultancy. We help you prepare, organise and follow up — the decision on your request always rests with the company, the Registrar and Transfer Agent (RTA), the depository or the relevant authority.
Expected stages and possible delays
We cannot promise a completion date, because processing depends on third parties. Common reasons for delay include:
- Bank attestation time
- RTA scrutiny
- Further mismatches such as name or address
Frequently asked questions
Does my signature have to be the same as in 1990?
What if the signature mismatch is with a deceased joint holder?
