I have a shop in A apartment on the road side, and the way to enter in apartment for flat owners is far from my shop. As i bought this shop i have made shed of steel sheet roofing to secure place from being mess up by flat owner. I made this shed because flat owners through their waste materilas through balcony/ window in front of my shop. I think it is within the limit of my boundy. But a flat owner has filled an application to the Muncipal Corporation for "Encroachment on Common Property". So please tell me is it illegal to prevent flat owner to through their waste material in front of my shop by making shed of steel sheet roofing with steel pipe ?? and also it is my parking place , left by builder infront of each shop and flat owners haveing their own parking place behind my shop , below the building. Please answer.
