My father has gifted me the house ( only house) he owns. (Location Jamshedpur, Jharkhand). Now my sister is trying to get the share.My mother is also with her side. Although registered gift deed has been done, she is trying to put a case of forgery. As my father is very old , she is just waiting for him to be no more and then she can put a case claiming that I had influenced my father for this gift deed. Since presently my father is alive, she can not take any action. She has also approached lawyers who executed the gift deed and bribed them. They have suggested her to wait till father is no more and then they can help her to prove that this gift was done under undue influence. all three the witnesses are from lawyer's firm, he and his 2 employees, what safeguard should I take to avoid this situation when my father will not be with us. Kindly suggest.
