We have a tree that is leaning toward our neighbor's property. It is currently not over the property line, but would fall in that direction. The neighbor has recently chosen to park a car under the estimated fall-line. We have warned them a long time ago about that, as they used to park a camper in roughly the same spot. Should we write them a letter advising to move the vehicle until we can take the tree down? Do we legally need to take the tree down? Who is ultimatley liable if it falls in an "act of God" - wind, snow, etc.
