My father passed away leaving behind agricultural property of 11 acres to me, sister and mother. He registered 3 acres as gift to my mother. What would be legal right of me and my sister for already gifted property to Mom? We want to split and register inherited property now and it would be at different ratio as there was some property bought my father on my sister name directly after her marriage directly on her name as gift and some of the land was bought by him with money given by me. We are agreeing to split as per ratios now calculating all money I have and was given to my sister. What documents are needed now so that the claim for equal value is avoided in future in court in case any filed with greed.
