Others — Wrong placement of plotting stone

Sir, I have a residential plot no. 109 at Sri Selva Vignesh Nagar, Kandigaivillage, Bunrutty near Oragadam. My neighbour had wrongly plotted the marking stones in my plot and am not aware of his whereabouts. Kindly advise the procedure to remove the plotted stones from my plot. Secondly, I have a farm land as plots which is not approved and have sale deed and patta with me. Now I wanted to get it approved. What are the procedures for that? K. R. Venkatesh
