I recently purchased some land which contains a "short-cut" road connecting two public roads. The locals have been using the road for 20+ years. There is no easement or right-of-way in the deed or property description. I constructed two gates at each end of the road several months ago. I don't think anyone cares enough to file a suit but I am concerned someone may file for prescriptive easement. What is the time-limit they have to make a claim against me? Is there anything I can do to protect my property from a prescriptive easement?
