MO HB1664

Defines adverse possession as occupying another's real property in a manner that would give the owner cause for ejectment, with or without knowledge of the owner's superior ownership rights.

Grants title to adverse possessors upon expiration of the statute of limitations if occupancy is adverse, under claim of right, open and notorious, continuous, exclusive, and actual.

Establishes a 10-year period for adverse possession claims based on a written instrument, court decree, or judgment, with specific standards for what constitutes possession depending on property type and use.

Provides that de minimus nonstructural encroachments (fences, hedges, sheds, walls) and lawn mowing across boundary lines are deemed permissive and do not qualify as adverse possession.

Specifies that landlord-tenant relationships and tenancy-in-common relationships preserve the original owner's possession rights for up to 10 years after the relationship ends, after which the tenant may claim adverse possession.
