W. Va. Code § 37-1-14

In case such sale or lease be made, the guardian or committee shall enter into bond, with approved security, conditioned for the faithful application of the proceeds of sale or lease. And in case of a mortgage or trust deed such guardian or committee shall enter into bond, with approved security, conditioned for the faithful application of any moneys which may come into his hands from the encumbrancing. In either case such bonds shall be taken in open court, or before the judge in vacation, or before the clerk, and shall be payable to the state, in such penalty as shall be prescribed by the court; and the court may thereafter order a new bond, with other security, to be given if deemed necessary. If the court shall find that the bond already given by the guardian or committee is sufficient, no additional bond need be required.
