A & B were joint shareholders. They were holding equity shares in physical form. A died in 2007. B died in 2011. High Court determined C & D as successors of B because at the time of death of B, he was the sole shareholder (though on share certificate, name of A was not deleted). One of the companies raised objection and demanded succession certificate in the name of A also for transmission of shares to C & D. Please advise.
