Re: Adverse Possesion in Idaho
the statutes I find require an adverse possession of 20 years and the payment of taxes to boot.
Regardless of what may or may not be actionable by the possessor, it is always in your best interest to nip things like this in the bud. You need to explain the situation to the neighbor and kindly ask him to relinquish any activities upon your land without your express permission. I would also contact the real estate agent involved and alert them to the situation so they do not misrepresent the lot to a prospective buyer.
and you wouldn't be moving the property line, just that acceptance of where it actually is. What is the reason for not wanting to claim your property (at least that is what it sounds like to me anyway)
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
