Neighborhood Law Saxony / Boundary Construction

Building materials are being unloaded and stored on someone else's property, then the crane comes and is set up on someone else's property ... such things can be discussed in advance out of decency, no one would care about that. But it's the tone that makes the music.

You don't want to open that, but your posts and questions around the topic are focused on security and confrontation. You urgently should talk to each other after you have clarified for yourself what you want.

hm... you should probably tell that to the person who saw your property not as foreign, but as that of his friend ;)
