We have a around of 10 acres of ancestral land property that got to my grandfather by partition done between his father and brothers on 1925. My grandfather died on 1965. He did not make will or partition anything. He had have 3 Sons and One Daughter. His 3 Sons and One Daughter died on respectively 1971,1980,1987 and 1989. UDR Patta had been issued on 1987 in our joint names i.e. 13 heirs of Sons of grandfather. We have currently got computer patta in our joint names. My Aunt's(daughter of grandfather) husband and two sons are alive. They inform that they are likely to take share in the above property meanwhile we like to do partition now. My grandfather had given my aunt One Acre land by settlement deed in his individual property on 1957. My question is:
1. Is correct they are likely to take the share?
2. If yes, How many shares are to be given them in the above 10 Acre property?
