Adverse Possession in Washington
State-specific overview · Property & Real Estate
Washington requires 10 years of continuous possession plus payment of property taxes to claim adverse possession.
How Washington treats Adverse Possession
Washington's adverse possession statute requires a 10-year period of open, notorious, exclusive, and continuous possession, combined with payment of property taxes during that time. The tax payment requirement is a distinctive feature that strengthens the adverse possessor's claim by demonstrating commitment to the property. Washington courts interpret the 'hostile' element broadly, including cases where the possessor acts without the owner's permission, even if unaware of trespassing.
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.
