My neighbor has a tree on their yard, and one of the big branches is partly dangling from the trunk. Problem is the end part of that big branch has landed onto my property. I'm afraid if I try to move the end of the branch to get it off my property, it might take the whole branch down. If that happens, 95% of that branch will fall onto their property, but I'm afraid they might blame me for what happened. Shouldn't the neighbor take down that branch or am I responsible?
