Share certificate and transfer

Dear All, I have purchased a ready to possess flat from the Transferor before the Society was formed. The Transferor is a promoter and subscriber to many application forms for formation of the Society and the Builder is the Chief Promoter. I had obtained a NOC from the builder at the time of purchasing the flat. Now on obtaining the Registration Certificate, should the Share Certificate be issued in my name or in the name of the Transferor and thereafter transferred in my name? If issued in the name of the Transferor, then whether the Society is entitled to Transfer premium on transfer of Share Certificate in my name (although the Transfer took place before Society was formed)?
