Va. Code Ann. § 58.1-1830

An order of exoneration under §§ 58.1-1826, 58.1-1827 or § 58.1-1828, when delivered to the Tax Commissioner, shall restrain him from collecting so much as is thus erroneously charged. If what was so erroneously charged has been paid, the order of the court under §§ 58.1-1826, 58.1-1827 or § 58.1-1828, when presented to the appropriate state or local official, shall serve as the only direction necessary to obtain refund of the amount so ordered.
