My father had 2wives and 1st wife expires 2yrs back. He has 3daughters from first wife and 2daughters and a son from 2nd wife. Iam the only son from 2nd wife. My father wants to transfer a house to me and the this property is self earned by him. He as already done a registered will in my name but he is afraid that in future it may have legal complication from daughters. I want to know what is the better way to transfer property in this case so that no legal complication should not arise?
