W. Va. Code § 54-2-1: Jurisdiction.

In any case in which property may lawfully be taken for a public use, application may be made by petition to the circuit court or the judge thereof in vacation, of the county in which the estate is situated, to appoint commissioners to ascertain a just compensation to the owners of the estate proposed to be taken. If a tract lies partly in one county and partly in another, the application in relation thereto may be made in either county.
