If you have inherited physical shares from a deceased person and want to Dematerialize them, you must contact the company's RTA (Registrar and Transfer Agency) and request that the name on the business records be changed to your name as it appears on your Demat account.

Note:
1. If a joint holder of a share dies, the surviving holder(s) can have the physical shares Dematerialized into their Demat account by submitting a notarized copy of the deceased holder's death certificate, the duly filled Transmission-cum-Dematerialization form, and the normal set of Dematerialization documents listed here.

2. If the shares you're trying to Dematerialize are on this CDSL list, you'll be able to send them for Dematerialization only when the name of the scrip is removed from the list.
