Transmission is the process by which securities of a deceased account holder are transferred to the account of the surviving joint holder(s)/nominee/legal heirs of the deceased account holder. Process of transmission in case of dematerialized holdings is more convenient as the 13 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 surviving joint holder(s)/nominee/ legal heirs has to correspond independently with each company in which shares are held.
