Land owner had mentioned Wrong plot Number in sale deed (that plot Number Of another place where harvest land near pond there is no any four way as mentioned in our sale deed) Note: Harvest land also same owner Land owner is not agreed to rectify plot number any how they asking 1 lacs for rectify and ask me to first withdraw and quash case and give 1 lac Rs then we will go for Rectification with new sale deed else you can go and take any legal action. Note: case registered in civil court- Bansgaon and also registered crime district court- gorakhpur But below points are correct in sale deed on Stamp 1- Four way beside my land is corrected 2- Location is correct . 3- Even after sold which land we had bought they sold another property in right side of my land where he has mentioned my mother name(Reeta Tripathi) as owner in four way of my neighbor sale deed. 4- Electricity bill is my name . 5- pradhan mantri toilet alloted to mine. 6- we have Receipt of Bricks of my constructed house.
