You apparently seem to have suddenly discovered that you have inherited shares 15 years back. What were you doing all these years? Anyways nothing is lost, so relax. This used to be a common problem in the physical certificate days. Investors would keep the share certificates in their locker and entirely forget about. Quite often, in cases of HUFs, the Karta would have access to all these certificates and the event of his death; others would not even know anything about these certificates. The bigger risk was loss in transit, which was common when these certificates were sent through post. A loss would mean going through the complete police FIR route to get fresh certificates issued.
Your problem is that you inherited the share certificates 15 years back but you are not aware it. Not worry. There is something called a Transmission cum Demat form that you can fill up for the same. Remember that while transfer-cum-demat has been discontinued, the transmission –cum-demat facility is still available. So, you can thank God for that. You will have to first execute the transmission application form to convert the shares into your name and simultaneously dematerialize the same. Once the registrar is satisfied with the genuineness of the transmission form, the said shares will be dematerialized and credited into your demat account. Check the properness of your grandfather’s name in the share certificates and your name in the DP account before the below form…
The procedure for transmission-cum-demat is fairly simple! It just involves filling up the TCD form and attaching a copy of the death certificate. It may have to be notarized and also attested since it is more than15 years old. Once the RTA is satisfied, these shares will be transmitted to you and you will get the credit n your individual demat account.
