Welcome! My goal is to do my very best to understand your situation and to provide a full and complete answer for you.
Good afternoon. There is a clear-cut rule regarding trees in this situation. It depends upon whether you, as the owner of the tree, knew or should have known the tree was previously damaged or diseased. If the answer to that is yes, then you, being the owner of the tree (or your insurance company), are responsible for the removal of and any damages
caused by the tree. If the answer to that is no, then it would be considered an Act of God, and you, being the owner of the tree, have no liability for damage and are not responsible for the removal from the neighbor's property.
