I found one document of grandfather land registered in 1973. from 1973 to till EC shows that land belongs to my grandfather. But patta alone was in some other name who is not at all related to us. Verifying patta records it is clear that some fraud has happened in Revenue dept. Now i want to change patta to my grandfather name. But my grandfather is no more. Tahsildar told that he cannot change patta to grandfather name. How can i do this. I want to sell that land for my education. What is the right way to do this?
