A sitting tenant is someone who legally occupies a property without being the owner. Synonyms for a sitting tenant include a tenant in situ, a resident tenant, or a holdover tenant. A tenant in situ is someone who has stayed in a property for an extended period of time and has acquired legal rights to remain there. Similarly, a resident tenant is someone who stays in a property for an extended period of time, but has not acquired legal rights to remain there. A holdover tenant stays in a property beyond the end of their lease or rental agreement but has not signed a new lease or rental agreement with the landlord.
