Adverse Possession in Massachusetts
State-specific overview · Property & Real Estate
Massachusetts requires 20 years of continuous, open occupation to claim adverse possession of land.
How Massachusetts treats Adverse Possession
An adverse possessor must occupy the property openly, exclusively, and continuously for the full 20-year period without the owner's permission. Massachusetts courts strictly interpret the "open and notorious" requirement, meaning the occupation must be visible enough that a reasonable owner would notice it. The possessor's intent to claim ownership is not required; the focus is on actual possession and use of the land. Taxes need not be paid, though doing so strengthens the claim.
The general definition of Adverse Possession
Gaining legal ownership of land by occupying it openly and continuously for a set period.
If someone uses another person's land openly, without permission, and continuously for many years (typically 7–21 years depending on the state), they may eventually become the legal owner. The original owner must not have stopped them during that time. This doctrine rewards people who improve and maintain land while punishing owners who abandon or ignore their property.
