I sure hope that no-one on here would bash you for asking a question. It's pretty sad that some of us have to come on here with a legitimate question and plead to not be bashed or insulted. I'll see if there's anything I can find regarding it in the meantime. I do know that if it's a tree on a neighboring property and it's overhanging your property you can trim the branches on your side. However, I'm not sure about a fence. Again, I'll see what I can find if anything. Hope you get some nice answers to your question.
