My father has got a property from my grandfather through a gift settlement in Feb 2004. The said property was a self acquired by my grand father. Later my father has settled the property in my favour through a gift settlement in November 2007. Now my sister claims that since the property belongs to my grand father, my father has no right to give it to me as gift and she has the equal right. I would appreciate your clarification. Can my father cancel the deed in favour my sister ? There is no conditional clause in the deed and it was stated as immediate possesion tranfer to me.
