We have purchased a land around 4 years before from two brothers. The land was actually in the name of their Mother, who is no more. They have produced legal hire certificate showing that they are the only, who have the ownership on the land after their parents passed away. We never knew that they have sisters also. We have taken a bank loan and purchased the land. After 3 months of purchase, two of their sisters filed a case for their share. That is the time, when we came to know that they have sisters. Anyways, it took around 1 year for an out of court settlement and two sisters have withdrawn the case. Now when we have started construction, other sisters are telling that they will file a case now. We are now in a state, where we are paying the EMI in the bank but not able to do anything on the land. We have all the legal documents as per land registration department to show our ownership. We have also paid the property tax regularly after purchasing the land. Please let me know a way out of it. My sincere gratitude in advance to those who can show me a way out.
