Neighbor Nuisance

Sir I have a plot with road on two sides of it( Nagar palika constructed), I want to put a gate on my plot but I am being threatened by the person who is living on the opposite side of the road, saying that this is his private road and says he won't let me put the gate on the other side too, as he wants to purchase the property at nominal price by making it disputed. So, I went to the police for the same and they made a report in which they mentioned it has common road on two sides of it, but they send my complaint to the revenue department( Tehsildar) and he asked a Lekhpal to provide cognizance on the same but he being a corrupt one made the report against me saying that my family members did plotting on our land without a layout(area about 0.89 hectare) but it was divided into four brothers and later on divided between sons of four brothers. Lekhpal mentioned in his report that the family members of mine did plotting without a layout, so no action can be taken from their end and I was asked to file a lawsuit in the court for the same, this is what the rival party wants so that my land becomes disputed. What should I do?
