Adverse Possession Explained: The Five Elements and How Exams Test Them

Adverse possession lets someone gain title to land by possessing it for a statutory period under certain conditions. It's one of the first big rules in Property, and it shows up on exams because each element has gray areas.

The rule: To acquire title by adverse possession, the possessor's use must be actual, open and notorious, exclusive, hostile, and continuous for the statutory period.

Some students remember the elements with the mnemonic COAH plus exclusive: Continuous, Open and notorious, Actual, Hostile, and Exclusive.

Actual

The possessor must physically use the land the way a true owner would. Living there, farming, building, or fencing usually counts. Occasional walks usually don't. Under constructive possession, someone who actually possesses part of a parcel under color of title (a defective deed) may be treated as possessing the whole parcel described in the deed.

Open and notorious

The use must be visible enough that a reasonable owner inspecting the property would notice it. Hidden use, like an underground encroachment the owner couldn't see, often fails this element.

Exclusive

The possessor can't be sharing possession with the true owner or the general public. Sharing with a few people the possessor allows on the land is generally fine.

Hostile

The use must be without the owner's permission. Courts take different views on the possessor's state of mind:

• Objective standard (majority): state of mind doesn't matter; what matters is that the use wasn't permitted.
• Good faith standard: the possessor must have believed they owned the land.
• Aggressive trespass standard: the possessor must have known it wasn't theirs and intended to take it anyway.

Permission defeats hostility. If the owner granted permission, the clock doesn't start until the permission ends and the possessor asserts ownership.

Continuous

The possession must be uninterrupted for the statutory period, which varies by state. Seasonal use can satisfy continuity if that's how a typical owner would use that type of property, like a summer cabin.

Tacking: successive possessors can add their periods together if they're in privity, meaning the possession was transferred voluntarily, for example by sale, gift, or inheritance. An ouster breaks privity.

Disabilities: if the true owner was under a disability (such as being a minor) when the adverse possession began, many statutes extend the period. A disability that arises after possession starts usually doesn't affect the clock.

Writing the analysis

List the five elements, then take each one against the facts. Spend your time on the element the facts are designed to test. If the possessor mowed a strip of lawn each summer and went away each winter, the fight is about continuity and maybe actual use. If the owner said "go ahead, use it" years ago, hostility is the issue.
