Please advise for following case:
A (Father) acquired plot of land and build his house. He died without a will. So, land has been shared between his widow (W) and three children (Lets say B, C, D) in eequal share i.e each has a 25% share in the land. B is A's son and has 3 children of his own - 2 daughters and one son.
1) Do B's children have an automatic/legal right in B's share of the property?
2) Can B will his share of 25% to anyone of his choice (either to his wife or any child or any third person) in whatever proportion he wishes?In such case, can B's will be contested by either his wife or children or even grandchildren?
