The precarium (plural precaria)—or precaria (plural precariae) in the feminine form—is a form of land tenure in which a petitioner (grantee) receives a property for a specific amount of time without any change of ownership. The precarium is thus a free gift made on request (or precarius, whence "prayer") and can be revoked. The grantor can reclaim the land and evict the grantee at any time, and the grantee's hold on the land is said to be "precarious".
