How much land is in dispute?
I'm sure you'll win. Modern surveying is pretty accurate. People get funny ideas in their heads about where lines are though.
They are literally disputing about 20 feet on a single marker, that is holding up fence construction along a 1/3rd mile border segment.
Offered to buy their property and was shouted down.
Even offered to fix the fence at my expense, if they provide me a valid, signed and stamped survey that contests mine.
They are refusing to let me proceed until they have time to get their own survey (A pointless waiting tactic that I've had enough of)
Lawfare it is.
When I run into stuff like this I can only think that an immutable decentralised ledger of some form that publicly holds the truth of things would be so much better. All land should be on some blockchain breaking down the exact coordinates of the land. Actually, I know someone who was working on this years ago.
There's no reason people can't trade their well defined property easily.
