My brother owned a property of 300 yards land which he got from my father(self acquired). He has one son and one daughter. Due to unavoidable circumstances he has taken 5 lakh from one person on credit basis and signed innocently on a blank stamp paper. Now the person who lend the money has created papers in such a way that he has sold the entire land to him for 50 lakhs and filed case and got injuction order from court. It is cleraly a fraud and cheating done to him.Now, how he can come out of this probelm? Whether the children will get their fathers property? please advise to help a needy.
