I have heard over and over that in NC its illegal to hunt on someone elses land without permission but I have yet to see that in writing. What I have found in the hunting regulations is that its not nice to hunt on someone elses land without permission. Some counties, and mine is one of them thankfully, do have an orginance that requires written permission of the land owner so at least hunters can be written up.
The NC Extension service has a pretty good website. I happened to be on the site a week or so ago and read the page they have on land owner liability issues for the upteenth time. The best protection an NC landowner can have from liability issues is to post the land and enforce the posting. The person coming into the posted land has now committed a criminal act and their ability to sue the landowner is reduced. If the land was not posted then there is no criminal act and they have more room to sue. If you let someone on your land to hunt, walk, take firewood, etc, there is more onus on the landowner and thus they have more room to sue. The worse thing, liability wise that is, a landowner can do is take money from someone to come onto their land to hunt, walk, take firewood etc. So in those cases you need to get a contract to remove your liability from those invitees. Not sure how well that works.
I just post the land and go after people as required. I have cleared all of the property lines where I know the locations of the lines. I'm going to have to spend some money to get the other lines marked. Hopefully this next winter I'll be able to widen the clearing along to the property lines to get the tractor in so things will be easier to keep clean. I have painted trees, put up T posts next to survey pipes, and put up posted signs. Where I don't know the exact location of a line I just put the sign so I know its on my land. The signs last 2-3 years before rotting away. But at least I've got most of the lines cleared now thanks to the DR Mower and its much easier now.
