Hello. My name is Kumar. My father purchased a commercial property from Mr. X in Andhrapradesh in 1976 and it was registered on his name. Mr. X 's brother sold the same property to one of my relatives in 1984. We came to know about this recently. There was no construction made on this property since its purchase and now all of sudden my relative shows a registered document done in 1984 that he purchased from Mr.X's brother.
we want to start construction in that land. My father has registration from Mr.X in 1976 and my relative has registration from Mr.X's brother done in 1984. If 2 brothers sell the same property at different times, is the second registration valid? If my father approaches court, what are his chances of winning?
Thank you for your advice
