A tenant at sufferance arises where a tenant, having valid tenancy, holds over without the landlord’s assent or dissent. Such a tenant differs from a trespasser in that his (tenant at sufferance) original entry was lawful. A tenancy at sufferance, in these days of most States enacting Landlord and Tenant laws, has become better described as a Statutory Tenant – though his contractual tenancy period has expired he continues as under the Landlord and Tenant law of the particular State, especially as regards what his rent is and how the premises may be lawfully recovered or repossessed from him. A tenant at will in that his tenancy exists with the landlord’s assent but without being period-defined; he stays at the will and mercy of the landlord. His tenancy may be converted into a yearly or other periodic tenancy in the usual way. A trespasser is one who enters into occupation without permission or unlawfully occupies from the point of entry. See African Petroleum Ltd V. Owodunni (1991) NWLR (Pt. 210) 391 Abeke v.
