We have been mowing the land adjacent to ours for 20+ years. We do know who the owne is, but as it is a little more than an acre and is at the edge of our property we have taken care of it. The owner recently died and her son had the land surveyed. We attempted to find out what their plans were for it, but no one has called us back. Can we attempt to take over this land under squatters rights? No one has visited that land since we've been attending to it.
