Whether an adverse possessor's actual knowledge that another person holds legal title, without more, defeats the requirement that possession be hostile and under a claim of right.
Holding
No. Actual knowledge of the title owner's interest does not, by itself, defeat a claim of right or prevent adverse possession.
Reasoning
New York requires adverse possession to be hostile and under a claim of right, but a claim of right means possession that is adverse to and inconsistent with the true owner's rights. The controlling focus is the possessor's objective occupation and conduct, not the possessor's unexpressed state of mind or knowledge of the record title.
The Court relied on longstanding precedent, beginning with Humbert v. Trinity Church, establishing that a possessor's knowledge that another holds title does not answer an otherwise valid adverse-possession claim. The doctrine turns on actual occupation under a claim of ownership for the statutory period, not on whether the possessor knew that the occupation was legally wrongful.
The true owner's acquiescence is central. When an owner permits an open exercise of hostile ownership to continue through the statutory period, that failure to act allows title to mature in the adverse possessor. Here, the Przybylos waited until 2004—nearly 10 years after moving in and almost 15 years after purchasing lot 23—to assert their rights.
