Maryland Adverse Possession Laws

Maybe you’ve come across a story or two about urban squatters taking over a downtown building, or about someone who had a bunch of land out in the country but lost some of it to trespassers. Under the law, the act of trespassing for so long that you gain a right of ownership or pass-through is called “adverse possession,” and can be pretty disconcerting to a layperson. So how does adverse possession work, and how does the Old Line State treat cases under state law? This is a brief summary of adverse possession laws in Maryland.

Adverse Possession Laws in General

As noted above, the legal doctrine known as "adverse possession" stretches back a long way and is designed to encourage landowners to keep an eye on and make beneficial use of their land. The concept allows trespassers to gain legal title to property by openly inhabiting and improving the property and meeting some other specific conditions. Under Maryland's adverse possession law, an individual must occupy property for at least 20 years before the possibility of ownership.

The minimum time requirement is not the only hurdle for adverse possession. A trespasser must also prove four additional elements to have a legitimate adverse possession claim:

  • There must be a “hostile” claim: the trespasser must either
    • Make an honest mistake (like relying on an incorrect deed);
    • Merely occupy the land (with or without knowledge that it is private property); or
    • Be aware of his or her trespassing;
  • There must be actual possession: the trespasser must be physically present on the land, treating it as his or her own;
  • There must be open and notorious possession: the act of trespassing cannot be secret; and
  • There must be exclusive and continuous possession: the trespasser cannot share possession with others, and must be in possession of the land for an uninterrupted period of time.
