W. Va. Code § 56-4-10
The proceedings in a suit wherein an infant or insane person is a party shall not be stayed because of such infancy or insanity, but the court in which the suit is pending, or the judge thereof in vacation, or the clerk thereof at rules, shall appoint some discreet and competent attorney-at-law as guardian ad litem to such infant or insane defendant, whether such defendant shall have been served with process or not, and after such appointment no process need be served on such infant or insane person. If no such attorney be found willing to act, the court, or the judge thereof in vacation, may compel him to act, or appoint some other discreet and proper person in his stead; but the attorney or other person so appointed shall not be liable for costs. Every guardian ad litem shall faithfully represent the interest or estate of the infant or insane person for whom he is appointed, and it shall be the duty of the court to see that the estate of such defendant is so represented and protected. And the court, or the judge thereof in vacation, whenever of opinion that the interest of an infant or insane person requires it, shall remove any guardian ad litem and appoint another in his stead. When, in any case, the court or judge is satisfied that the guardian ad litem has rendered substantial service to the estate of an infant or insane defendant, it may allow him reasonable compensation therefor, and his actual expenses, if any, to be paid out of the estate of such defendant.
