We purchased property that had an ingress/egress for the water company in 1989. In 1990 several people built houses around our property. We have been having problems with the neighbors thinking that the road on our property belongs to them and they can do as they want to. The neighbors also have other access to their property, it is just not as convenient for them. My question is how do I stop them from working on the road that is part of our property.
