Hi, in my opinion, what you can do is apply for a duplicate death certificate, that is have a new one made from the nearest Tehsildar's office (assuming it's within the jurisdiction of which your father resided/passed away.) As the event is decades old, perhaps you may have to pay a considerable fine.
