I am Rukmani aged 58 years from tamilnadu. My Grandfather bought an agricultural land in the year 1952. My grand father had two sons and three daughters. In the year 1976 a partition has been made between two sons (my father and his brother) and it has been registered. From that time onwards my father enjoys the sole right of the property.
My father had one son and two daughers (myself, elder sister and younger brother)
In the year 1999 he wrote a will (partitioned property 3.16 acres of agricultural land) in my son’s name and it has been registered.
Because they are not with my parents and myself looking after their health and day to day needs. My younger brother got a love marriage after that he never turned to my parents and also my elder sister, she never turned after her marriage. So my father wrote a will in my son’s name.
My father died in the year 2000 and my mother died in the year 2005.
My question is
1) Whether it is an ancestral property or not?
2) Whether My father has a right to write a will?
3) Whether my elder sister and younger brother can claim the share in the property?
