My mother in law want to give me some agriculture land. My wife is the only daughter of her. If I goes to make sale deed for it , cost would be around 5 Lakh. I am not in such position to bear this amount. Mother-in-law's other family members are opposing it and want to keep this property with them. I want to know how can I get this land on my /my wife name which can not be challenged in future after the death of mother-in-law. She already have make registered will , but chances are it will be challenged in court by her family member after her. What prevention I should take ? Please advice.
