Adverse possession allows a non‑owner to acquire title after meeting a statutory period of continuous, open, notorious, exclusive, and hostile possession. The “hostile” element simply means the occupancy is without the true owner’s consent, not that it is antagonistic.
All states recognize the five classic elements, but they diverge on the length of the required period, the necessity of paying property taxes, and whether the land must be used for a particular purpose, such as residence or cultivation.
