I am from Tamil Nadu, I will explain the problem in more detail, my grandfather and grandmother was a farmer, they bought the land with their own money, further they documented it as both have equal share in the land. They had one son and three daughters, the son (not married) and one daughter (my mother) died long back. One daughter lives on the same village and another daughter far away and both are married. My grandparents gave their land document as a security for my education loan and I rapid the loan, gave back the documents. Soon after my education, I started to take care of them financially and they stopped working in the field, three years back my grandfather got mentally and physically ill and I took him to the hospital. The doctors said he is mentally ill (got afraid of every sound and every one) and also he has kidney problem. We are taking medicines regularly.

The problem arrived recently; the daughter living in the same village took him for 10 days in her home and secretly registers the land in her name. Now he is back to his home and we heard about it. We caught shocked, me and his another daughter helping them both financially and morally. Moreover he is mentally ill, how she can take him and register the land of his share? We still have all the original documents with us and including his medical certificates. We confirmed it in registration office about the registration of the land. She is not the kind of person we can talk and solve the problem. Please kindly advise me how to legally solve this problem.

Thank you in advance for your help
