Va. Code Ann. § 17.1-609

Upon any motion, other than for a judgment for money, or upon any interlocutory order or proceeding, the court may give or refuse costs, at its discretion, unless otherwise provided. It may, when a demurrer is sustained to a plea in abatement, give judgment for the plaintiff for his full costs, to the time of sustaining it, an attorney's fee only excepted; and when any other part of the pleading is adjudged insufficient, order all costs occasioned by such insufficient pleading to be paid by him who committed the fault.
