There is a agricultural land and the owner of the land is belongs to SC/ST. The land is converted into residential land in 2003 under section 143(k). Then this land is taken by a property dealer and the same is sell out to other customer in the form of plot without changing the name of original owner that is SC/ST in the gov paper KHASARA. The second person purchase the land and also not implemented the name the original owner i.e. SC/ST. Then third person (myself) purchase the on confusion that the land is residential and name is transfer on later.So that third person purchase the land in the court by registry with paying all govt fees. After that third purchaser approach to the court for change the name in Govt record as KHASARA then the lawyer refused and saying that the land is belong to SC/ST and the name of record can not be changed. Please guide me what rule to be use for convert the name of original owner to myself in Govt paper i.e KHASARA. If name can't be change then how I will produce our self owner of this land in front of the Govt. What are the problems arises & face by myself in the future.
