Is it required to Execute the revised Gift Deed

Hi, Namaskaram, I represent a registered Trust which has some 10 acres of land. Prior me, my father was managing the activities of the trust and during his tenure as a member of Trustee, he executed a gift deed 0f 7 acres of land to Tirumala Tirupathi Devastanams upon the resolution passed by the other trustee's. There was some objection raised by locals during this transaction and it took 3 years to sort it out and now the objection is resolved. My father, who executed the gift deed in favor of T.T.D expired last year. Now T.T.D requested the Trust to registered the revised gift deed as the earlier gift deed is acceptable subsequent to the death of the donor as it is not valid in law. My question: The earlier gift deed execution is done by my father as a representation to the Trust and upon the resolution passed by the Trustee members. The Trust still exists and elected me to my father's role. Should we really required to re execute the revised gift deed as requested by T.T.D or is there any law that can help us to go ahead with the earlier registered gift deed. Thank you
