My father had bequeathed his residential house in Navi Mumbai, Maharashtra to me through a registered will made in 2013. I have a younger sister (married). My father recently sold the house and has kept the sale proceeds in a savings account jointly held by him and me. My father has given me the entire sale proceeds after taxation since he had originally bequeathed the house to me through his will. Since my father has sold the house while he's alive (and since nature of property has changed from immovable to movable) is there any need for further legal documentation e.g. codicil, gift deed etc.?
