W. Va. Code § 44-2-4

When the fiduciary commissioner has fixed the time for presentation of claims, the personal representative shall file with such fiduciary commissioner a list of the names and post- office addresses of all known creditors of the estate and of all distributees and legatees, to each of whom the fiduciary commissioner shall cause a copy of such notice to be forwarded by United States mail, addressed according to such list. But failure to mail, or to receive, such notice shall not relieve any creditor, distributee or legatee of the duty to present and prove his claim as required by such notice, nor in any way affect the proceedings pursuant to such notice.
