Z is my grandfather and A is my father and B is my uncle. Z and B have passed away. B died several years after Z. While Z was alive , all the agriculture land was shared accept 12 acres. This 12 acres was in the name of B even after Z died as A and B lived together in harmony. Recently A and B decided to stay separately and in the unshared 12 acres, B is supposed to get 8 acres and A is supposed to 4 acres. All these details were put into a white paper while Z was alive in 1974. Unfortunately B died recently and he has wife and 2 daughter who are minors . Wife of B got all the B's properties into her name and her 2 minor daughters. Now A is asking for his pending share of 4 acres and wife of B is not agreeing. I would appreciate any suggestion on this issue we are facing.
