Sir We bought a plot in 2007 beside Road and all direction house owner name mention in my stamp paper but after some time I saw my plot number mention in stamp paper wrong also in registry and around plot and road name is correct except plot number ( mention plot number in stamp of another location) we verify immediately that's eventually I saw wrong and then we insist to owner to please do correct the number of my plot he refused. Then we file case in civil court 420, 419 and now 8 year over there didn't give out any conclusion of court Please suggest me what I have to do 8 year we lost for this case can it be correct by high court? Owner are not ready to do correction this number Without owner can I do?
