Destruction Of Property Before Home Purchase.

Location: North Carolina
I purchased a home in 2024. When I received my boundary survey, the location of my wooden fence was clearly on my property. Looking back on photos from 2023 and back, the wooden fence always appeared to be completely on my property and was used by the resident who lived there.

When I purchased the house, part of the wooden fence had disappeared and new wooden posts were put up as if they were working on it, but it hadn’t been completed (the home needed some work so it wasn’t a red flag).

About a year ago 2025, my neighbor, a renter for 10 years who does light construction for work, tells me his land lord owns whole the fence plus a couple feet in. A couple months later I meet the land lord while he is pulling out the survey marker in the front corner and he tells me he put in the wooden posts for the fence and the whole fence belongs to him plus a couple feet in (we tell him to put the survey marker back where it was). He tells my actual boundary pin in the street (it’s not) and proceeds to tell me where my property boundary is (what he indicated was off the wall- he goes on to tell us that he is an amateur surveyor ). I walked him around my property and sent him my survey. My front two property makers do not align with the back four (There is a bit more to this that is also sketchy on the landlord’s part…) Anyways, he and his tenant have been a nightmare since.
…So, I’m on Apple Maps yesterday and I literally see him and his tenant on the street in 2023, the tenant is getting out of his van in my front yard and work is being as done on my home before it went on the market. At this time orange cable was being installed and it looks as if one property markers had been ripped out to do the work. The old wooden fence is still in place at this time.

What can I legally do to correct this situation? The land lord is claiming whole the fence is his because of the survey pin location (having a change of story since the first time we met) and has made quite the fuss. He put rebar into the ground, spray painted it pink and stung pink string (that is a super crooked line that goes about 5’ into my property on a strait lot line). Moreover, the location of the pin would cut part of the fence at a diagonal if I was just to realistically concede the couple feet to satisfy the location of this marker). The pin could have been moved by the cable company or my neighbor, the armature surveyor.

Any suggestions of how to get the pin the correct location? My survey company will not move it. Does my neighbor have a case for adverse possession because of the misplaced marker?
