Which of the following is NOT a requirement of adverse possession?

In the context of adverse possession, a claimant must meet specific legal criteria to successfully claim ownership of land that is not theirs. The requirements typically include exclusivity, hostility, and continuity of possession.

Voluntary possession is not a requirement for adverse possession. Instead, the "hostile" requirement indicates that the possession must be without the permission of the original owner, which is a crucial aspect of how adverse possession works. When someone occupies land that they do not own without the consent of the rightful owner, it is considered hostile.

Additionally, possession must be exclusive, meaning that the claimant is the only one using the property, and continuous, which ensures that the possession is uninterrupted for a specified period, typically defined by state law.

Therefore, because voluntary possession implies that the occupant has the consent of the owner, which directly contradicts the hostility requirement, it does not align with the principles underlying adverse possession.
