Why a seller cares

A neighbor who has openly used a strip of your land for a decade or two can, in rare cases, claim it. It usually surfaces at a survey, and it is a reason a fence a foot over the line is worth knowing about before a sale.

A simple example

Your neighbor's driveway has crossed your line by three feet since 2004, in the open, with nobody objecting. A buyer's survey finds it.

Adverse possession: a simple example
What the survey showsWhat tends to follow
A long, open, unchallenged useA title question the buyer's lender wants resolved
A boundary agreement signed with the neighborThe line is settled and the sale proceeds
A quiet title actionMonths, a lawyer, and a court's answer

Adverse possession is rare, and a survey is where it stops being theoretical.

What people get wrong

That it happens quietly. Every state's test includes open and obvious use for many years; a hidden use does not count.
