In any subsequent child support enforcement proceeding between the parties, upon sufficient showing that diligent effort was made to ascertain the location of a party, that party may be served with any required notice by delivery of the written notice to that party’s residential or business address as filed with the court pursuant to § 20-60.3 or the Department, or if changed, as shown in the records of the Department or the court or by electronic means as defined in § 63.2-1900. However, any person served with notice as provided in this section may challenge, in a subsequent judicial proceeding, an order entered based upon such service on the grounds that he did not receive the notice and enforcement of the order would constitute manifest injustice.
