Case Brief Summary & Legal Analysis

General Brief
4 min read

tl;dr: A homeowner’s steps encroached 15 inches onto a neighbor’s property due to a mistake. The court rejected the old rule requiring intentional hostility for adverse possession but found the minor encroachment was not “notorious” enough to give the true owner notice without actual knowledge.

Legal Significance: This case is significant for rejecting the “Maine doctrine” on hostility in adverse possession, holding that a mistaken belief of ownership is sufficient. It also established that minor boundary encroachments do not create a presumption of notice to the true owner, requiring actual knowledge instead.

Case Facts & Court Holding

Key Facts & Case Background

Defendant Gorski and her husband acquired a residential lot in 1946. That same year, they made improvements, including concrete steps and a walkway that encroached 15 inches onto the adjacent lot. The encroachment was unintentional, resulting from a mistaken belief about the property line’s location. In 1953, plaintiffs Mannillo acquired title to the adjacent lot. After the 20-year statutory period for adverse possession had passed, the Mannillos discovered the encroachment via a survey and filed suit to enjoin the trespass. Gorski counterclaimed, asserting she had acquired title to the 15-inch strip through adverse possession. The trial court found that Gorski’s possession was exclusive, continuous, and had lasted for the statutory period. However, it denied her claim because her possession was not “hostile” under the controlling New Jersey precedent (the “Maine doctrine”), which required a knowing, intentional taking rather than a mistake. The encroachment was minor and not self-evidently apparent without a survey.

Court Holding & Legal Precedent

Issue: Does a claimant’s mistaken belief of ownership satisfy the hostility and notoriety elements required to acquire title by adverse possession, particularly when the encroachment is minor?
