A person is seeking to reclaim ancestral land registered under their grandmother's name. They allege that a man named Om Prakash fraudulently transferred the land to himself in 1993 using a fake death certificate and a forged will. The original land allotment and mutation were in the grandmother's name in 1987-88. The user possesses certified copies of relevant documents and wants to know if they can cancel the current mutation and transfer the property back to their name as the rightful heir.
