Sometimes you just can't keep them happy. Having bought an 11 acre spread, I was the new guy. Noticed some folks bordering me were "using" part of my land. I had it surveyed. One neighbor agreed to move a small section of his fence a bit. I bought him a Tpost puller. We get along great today. The other neighbor was outside when the surveyor was present. He tried arguing with the surveyor about the line. Surveyor told him to pull a line on it, which he did. Owner says he wouldn't have bought this place if he knew the line was way over here. Surveyor was right but this neighbor was pissed off to no end when he found out my property was actually right next to his driveway and disrupted the mower access to his back yard. I asked neighbor to not build on it or do anything else with it, which he ignored. It's been years now, over 10, and we haven't had a word to each other once. I figured no big deal. Here is a guy who is pissed off because he can't use my property. I noticed he still mows about 3' onto my property. I may just fence it with some goat fencing to keep him off it. As someone said earlier, it is your land, you shouldn't have to justify keeping others off it. It seems to me some people just keep encroaching if you let them and don't defend yourself.
