Hindu family
A- father, B- wife, C-son1, C1- daughter of C, D-son2, D1- Wife of son2, D2- son of son2, E - a daughter.
A self - acquired 12 acres of land. A died in 1997 leaving behind legal heirs wifeB, Cson1, Dson2. So each of the 4 legal heirs is entitled to 3 acres each.
D(son 2 with inherited property of 3 acres) died in 2000 leaving behind legal heirs B mother, D1- wife and D2 son. Each of the legal heir is entitled to 1 acre.
So B(wife of A and mother of D) is entitled to 4 acres from 2000.
D1 and D2 sell 5 acres through a registered deed in 2008 to X eventhough they are entitled to 2 acres in total.
B writes 2 wills in favor of C1(daughter of C) - first is a registered one for 3 acres inherited from A as his wife; 2nd is an unregistered on for 1 acre which she inherited from D as his mother.
B died in early 2016
Now my questions:
1) is the sale deed by D1 and D2 to X valid as they sold more than they are leglly entitled to?
2) if the sale deed is valid, Can X contest the wills written by B in favor of C1? ( both D1 and D2 are interested in the dispute anymore as they have sold their share already)
