I had bought a corner plot of size 9 by 15 mtr. The developer had put stones as marking around 15 yrs back. Today my neighbor plot owner started marking his plot of same size as mine. But with respect to his marking iam left with 8.6mtr instead of 9mtr . In actual his other side plot owner has encroached his plot a bit. I would like to know whether P T sheet (mapping of my plot) given by Govt stands good or the stone marking. And what steps do i take to get my plot in power dimension. i am thinking of getting a survey done by govt person. can the stone marking holds good or the govt PT sheet. as per my thinking the stone marking can be altered by anyone
