Claim of father's possessed property by daughter

2 years ago

My grandmother's father had been in possession of 1 bigha land whose pattadar/owner was another person belonging to King family and such possession has been recorded in Khatian Register. Later when father of my grandmother died, my grandmother and her only brother were in possession of said land, but still till then concerned land was recorded in the name of said another person belonging to king family and in the khatian Register name of my grandmother's father was mentioned as possessioner. During those period brother of my grandmother sold some parts of the land including to us by executing sale deed, but how it happened I could not understand. Later, may be in the year 1991, sons of my grandmother's  brother upon the consent of the original pattadar i. e. King, mutated their names in Circle Office. Now my question is whether we can claim the said property on behalf of our deceased grandmother? The Big question is said was recorded as possessed land and original pattadar was the King as per Record. Please help.
