My father-in-law is the owner of a plot on which a house has been built. about 3 years ago his son built a floor above that house. My father-in-law has 2 daughters and 1 son. His son then told his father that he will take care of both parents well and coaxed him to transfer the rights of the first floor to his name. As soon as the registration is done, he started ill treating both parents and giving them mental torture. He is also not taking any care about their health. In this situation is there any option of seeking the help of the law to revoke the transfer and take back the property?
