Property transfer in case of death

Dear Priyanka Madam,

As you have said one of the siblings is hostile the remaining ones could transfer their undivided share in the property to your aunt by release deed or gift deed taking into consideration the stamp duty factor (depending upon the State - here in Maharashtra it is negligible on both gift and release (if deceased property is released to ascendants or descendants)), by doing so you all be securing 80% to her the remaining 20% could be bought out or over some period of time there could be some sort of settlement and as a last resort there could be partition with the unwilling member.
