Transmission of securities procedures standardized; exchanges and depositories must amend rules and comply within the prescribed period. The circular mandates amendment of prior transmission guidance and directs stock exchanges and depositories to update listing agreements, byelaws and rules to implement simplified transmission procedures. Annexure A sets documentary requirements for physical securities transmission: nominee transmission requires a signed request, attested death certificate and PAN (with limited substitution); transmission without a nominee requires an affidavit of legal heirs and, depending on holding value, either succession documentation or specified alternatives such as NOC(s) and an indemnity bond.
