Alaska Adverse Possession (AS 09.45.052)

AS 09.45.052 provides that "the uninterrupted adverse notorious possession of real property under color and claim of title for seven years or more," or "the uninterrupted adverse notorious possession of real property for 10 years or more because of a good faith but mistaken belief that the real property lies within the boundaries of adjacent real property owned by the adverse claimant," is conclusively presumed to give title, except against the state or the United States. Alaska's 2003 amendment narrowed claims to these two paths, so a knowing trespasser cannot acquire title. A squatter with no lease and no qualifying claim is removed through court ejectment or an FED action, not self-help. Possession must be open, continuous, and hostile throughout.

No specific statutory penalty. A property owner removes an unlawful occupant through court ejectment or an FED eviction; criminal trespass charges may also apply. Adverse-possession title vests only when every statutory element is met for the full 7- or 10-year period.
