W. Va. Code § 37-6-12: Distress for rent; time and place; warrant.

Rent may be distrained for within one year after the time it becomes due, and not afterwards, whether the lease be ended or not. The distress shall be made by any sheriff or constable of the county wherein the premises yielding the rent or some part thereof may be or the goods liable to distress may be found, under a warrant from a justice founded upon the affidavit of the person claiming the rent, or his agent, that the amount of money or other thing to be distrained for (to be specified in the affidavit), as he verily believes, is justly due to the claimant for rent reserved upon contract from the person of whom it is claimed.
