How to add joint holder to physical share

I joined the forum to find a solution to an issue - one of physical shares has 2 certificates, 1 in my dads name and another in moms name. The demat account is in joint holder format, so the bank told us to get physical shares done in joint holder format for which the registrar advised we need to get a "share transfer form" to add the joint holder and send it to them with the certificates. But neither the bank nor the registrar are providing me this share transfer form. I see on the net Share transfer form 7 (b), is this the correct one? Because I feel that is only to transfer 100% shares to another person and not add joint holder. Pls advise.

u can get share transfer form from stock exchanges. As if the share is sold by individual and bought by joint holders, the form has to be filled and sent to the company's secretary or their transfer agents. then, the shares will be transferred in joint names and physical shares will be available. then go for demating.

Thank you for the reply. Have got it done
