W. Va. Code § 51-3-2: Use of private seal.

Until provided with an official seal, every clerk of such court may use his private seal or scroll by way of seal, in cases where the use of the seal is required by law or usage; and whenever so used, his attestation of the instrument, record or copy to which it is annexed shall set forth the fact that he is not provided with an official seal, and shall have the same force and effect as if an official seal was annexed.
