My grandfather (mother's father) being a self acquired property Owner left the Registered Will when he dies in the year 1977. He has 1 female and 2 male children. My mother got married in the year 1974. As per my grandfather's Will, my grand mother has to enjoy the property till her lifetime and after she dies, the property has to be shared equally by his 2 male children. My grand mother is still alive. I would like to know whether my mother is eligible as per Indian law to ask for share in the property.
