I need some clarification regarding the following dispute.
Two brothers B1 and B2, married, living with their families separately.
B2 who is younger, mentally affected 2 years soon after his marriage.
Father's land assets were properly partitioned among two brothers and legally documented by the year 1995, by their father. B2's wife sold some part of B2's partition land few years back. Today, B1's land asset has higher value today than B2's. So, B2's wife decided to get a share in B1's land. She decided to file a case in court, that B1, B2's father has cheated his mentally affected son B2(her husband) and contributed greater beneficiary share to B1 (and this is not true) and they need a share in B1's land asset. She has even approached some hospitals to produce fake proofs, to show him that her husband is mentally affected. Now the father of two sons, is worried and confused. Kindly help me in getting some clarification regarding this case and some advices from great legal experts from our nation, on approaching this dispute.
Thanks in advance,
