Adverse Possession in Delaware
State-specific overview · Property & Real Estate
Delaware requires 20 years of adverse possession, one of the longest periods in the nation.
How Delaware treats Adverse Possession
Delaware imposes a 20-year continuous occupation requirement, making it one of the most demanding states for adverse possession claims. The possession must be actual, open, notorious, exclusive, and hostile to the true owner's title. Delaware courts interpret these elements strictly, and the burden of proof rests entirely on the person claiming adverse possession.
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.
