Which of the following describes the conditions for alienation by adverse possession?

The concept of alienation by adverse possession involves a legal process that allows a person to claim ownership of land under certain conditions. Hostile possession of the property is a cornerstone condition of adverse possession, meaning that the possession must be contrary to the interests of the true owner. This possession is not necessarily aggressive but is conducted without the owner's permission, indicating a clear intention to claim the property.

When someone occupies a property under these conditions, they establish a claim that can ultimately lead to legal recognition of ownership if they fulfill additional criteria, such as continuous and open use of the property for a mandated period. This is crucial in establishing the legitimacy of their claim against the original owner's rights.

In contrast, the other choices do not align with the fundamental principles of adverse possession. Mutual agreement between parties suggests cooperation rather than the unilateral action required for adverse possession. Leasing the property to a third party does not reflect the continuous and open possession necessary for a successful claim, since the original owner retains rights during a lease. Likewise, a negotiated settlement implies a consensual transfer of ownership, which is incompatible with the idea of claiming property through adverse possession without the owner's knowledge or approval.
