I am planning to buy the property from my mother-in-laws. They were saying that we can do the Dhana settlement(deed) to transfer to my wife as they are the blood relations. My wife has yonger sister, she is ready to sign for witness. Is it safe to go for that? Eventhough I am going to pay them, they are suggesting to get as dhana settlement. Will it be a problem in future? Is it legal? What are the norms I need to follow to be on the safer side? My in-laws have some more properly. will I get equal share?
