In 1998 we bought a 47 acre farm with house from the F family. At the time they also owned a 7 acre parcel on our east side and 80 acres across the road. Since then, they've sold the 80 acres and are currently building a house on the seven acres. When the F family owned the property they sold to us, they used it for all farming purposes, including moving farm equipment down the driveway that they had sited beside our east property line. After selling our property to us, they moved their farm diesel tank to a spot adjacent to our driveway on their 7 acre plot. We have had continuing discussions with them concerning their continued use of the driveway as if they still owned it, including blocking our use of our only access with farm equipment and telling contractors that it was okay to use the driveway. When confronted with this, I was told that "they built the driveway and would continue to use it". We have a gate that we don't keep locked or closed because our house is half a mile from the road and we can't see who is arriving (like friends and relatives). How can we prevent a prescriptive easement of our driveway become permanent? Seem to be too many conflicting opinions--from granting them permission to continue doing what we don't want them to do or not even discussing it with them.
