We bought a house in gated community. Its been one and half years. There was no problem earlier. Then our neighbour house was built after six months next to us. Only empty area left between both of us are our middle 2 feet area for drainage and bore well purposes and neighbour 1.5 feet for bore purposes. Neighbour empty area starts from parking to whole house backside, our is only middle side portion. We have only access to our portion through neighbour passage from back side as well as front side. Now suddenly they want to built a wall in their area. For us our bore area will be fully blocked. What to do , Is there any way to stop this . Please let me know. Thanks in advance.
