Whether possession of land under a mistaken belief that it belongs to the possessor can satisfy the hostility requirement for adverse possession.
Holding
Yes. Possession under a mistaken claim of title may be hostile for adverse-possession purposes; a claimant need not knowingly intend to take another's land.
Reasoning
The Court rejected the prior New Jersey rule derived from the so-called Maine doctrine, under which a boundary mistake defeated hostility unless the possessor intended to claim the land even if it proved to lie beyond the possessor's deed. That approach perversely favored the deliberate trespasser over the honest but mistaken occupant.
The Court adopted the Connecticut doctrine: objective acts of possession, rather than the possessor's subjective awareness of wrongdoing, determine hostility. Entry and possession under a mistaken claim of title are sufficiently hostile when they are exclusive, continuous, uninterrupted, visible, and notorious for the statutory period.
Overruling the earlier mistake rule did not impair legitimate reliance interests. Whether an encroachment is deliberate or mistaken, the true owner is excluded from possession in the same way; the owner's failure to sue ordinarily results from not knowing of the encroachment, not from reliance on the possessor's state of mind.
