W. Va. Code § 16-5-32

To protect the integrity of vital records and to prevent the fraudulent use of certificates of birth of deceased persons, the state Registrar is authorized to match certificates of birth and death, in accordance with legislative rule which requires that the fact of death and the matching identities be determined with reasonable certainty and to post the fact of death to the appropriate birth certificate. Copies issued from certificates of birth marked deceased shall be similarly marked.
