What is transmission of demat securities?
Transmission is the process by which securities of a deceased account holder are transferred to the account of his legal heirs / nominee. Process of transmission in case of dematerialised holdings is more convenient as the transmission formalities for all securities held in a demat account can be completed by submitting documents to the DP, whereas in case of physical securities the legal heirs/nominee/surviving joint holder has to independently correspond with each company in which securities are held.

In the event of death of the sole holder, how the successors should claim the securities lying in the demat account?
The claimant should submit to the concerned DP an application Transmission Request Form (TRF) along with the following supporting documents

1.In case of death of sole holder where the sole holder has appointed a nominee, notarized copy of the death certificate is needed.

2.In case of death of the sole holder, where the sole holder has not appointed a nominee notarized copy of the death certificate is needed.

Any one of the below mentioned documents -

Succession certificate
Copy of probated will
Letter of Administration
The DP, after ensuring that the application is genuine, will transfer securities to the account of the claimant
The major advantage in case of dematerialised holdings is that the transmission formalities for all securities held with a DP can be completed by interaction with the DP alone, unlike in the case of physical share certificates, where the claimant will have to interact with each Issuing Company or its Registrar separately.

What is to be done if there are any discrepancies in transaction statement?
In case of any discrepancy in the transaction statement, one can contact his/her DP. If the discrepancy cannot be resolved at the DP level, one should approach the Depository.

Whom should one contact in case of any investor complaint / problem / query?
In case of any investor complaint / problem / query one may first contact his DP. If DP is unable to solve the complaint / problem / query one should approach concerned depository. If one is not satisfied one may approach SEBI. One may also approach SEBI directly.
