W. Va. Code § 6-2-16

Where it is provided by any section of this article, or any other section of this code, or shall be provided by any subsequent statute, that any new bond, or bonds in addition to one already given, may be required to be given by any officer, fiduciary, or any other person, if such new bond, when required, be given and accepted, the sureties in the former bond and their estates shall, except in cases where it is otherwise expressly provided, be discharged from all liability for any breach of duty committed by their principal after such new bond is given and accepted. If such additional bond, when required, be given and accepted, the former bond shall continue in force and have the same effect in all respects as if such additional bond had not been required, given, and accepted; except that in such case the sureties in the additional bond shall be jointly liable with the sureties in the former bond for any breach of duty committed by their principal after such additional bond was so given and accepted.
