W. Va. Code § 36-4-14: Covenant for quiet enjoyment.

A covenant by a lessor, "for the lessee's quiet enjoyment of his term," or a covenant of like import, shall have the same effect as a covenant that the lessee, his personal representatives and lawful assigns, paying the rent reserved, and performing his or their covenants, shall peaceably possess and enjoy the demised premises, for the term granted, without any interruption or disturbance from any person whatever.
