If I wish to add the name of my spouse, children or any other person, what procedure should I follow?

Addition of the name of a joint holder, even a family member, is considered as a "Transfer" and attracts stamp duty. A regular transfer deed would be required to be executed. Blank transfer deeds would be available with your local stockbroker / stock exchange. (Please refer question no.2 for stamp duty payable.) For enquiries on securities held in electronic form, please contact your depository participant.
