W. Va. Code § 38-1-11

If the grantor in the trust deed, or any person to whom such grantor shall have granted or assigned the property covered by such deed, or any cestui que trust of such trust deed, shall as provided in the preceding section, require the trustee to give bond, such trustee shall, before making any sale, or receiving any of the proceeds of such sale, give bond in a penalty at least equal to the full value of the property to be sold, with good security, before the clerk of the county court of the county where such property is, which bond and security shall be approved by such clerk, conditioned that he will faithfully perform his duty as such trustee, and account for and pay over, as required by law, all money that may come into his hands in the execution of such trust. Every such bond shall be filed by such clerk in his office, and recorded by him in the book in which the bonds of administrators are recorded. Every notice of sale by a trustee under a trust deed shall have appended to it the certificate of such clerk, that bond and security has been given by the trustee as required by law, if such bond be required as aforesaid, but the failure to give such bond shall not affect the title of any purchaser of such property at the trustee's sale, for value, and without notice of the fact that such bond had been required.
