b. If the obligor fails to take one of the actions in subsection a. of this section within 30 days of the postmark date of the notice and there is proof that service on the obligor was effective, the Probation Division shall file a certification with the court setting forth the obligor's non-compliance with the support order and the obligor's failure to respond to the written notice of the potential license suspension or revocation. If, based on the papers filed by the Probation Division, the court is satisfied that service on the obligor was effective as set forth in this section, it shall without need for further due process or hearing, enter a court order suspending or revoking all licenses held by the obligor. Upon the entry of the order, the Probation Division shall forward a copy to the obligor and all appropriate licensing authorities.
For the purposes of this section, the court may deem procedural due process requirements for notice and service of process to be met with respect to a party thereto upon delivery of written notice to the most recent residential or employer address filed with the Probation Division for that party. If a party fails to respond to a notice and no proof is available that the party received the notice, the Probation Division shall document to the court that it has made a diligent effort to locate the party by making inquiries that may include, but are not limited to: the United States Postal Service, the Division of Motor Vehicles in the Department of Transportation, the Division of Taxation in the Department of the Treasury and the Departments of Labor and Corrections. The Probation Division shall provide an affidavit to the court presenting such documentation of its diligent effort, which certifies its inability to locate the party, before any adverse action is taken based upon the party's failure to respond to the notice.
