In the event of a default of payment, the Agency shall be authorized to secure collection of promised contributions from the defaulting unit of local government by court order authorizing the interception of or turning over of:
Any interception authorized under this Section by the Agency shall be valid and binding from the time the interception order is made until the defaulting unit of local government has paid in full its past due obligations to the Agency and has been current in its obligations to the Agency for a minimum of 12 months. The revenues, monies, and other funds intercepted and to be intercepted by the Agency shall immediately be subject to the Agency's lien. The lien shall be valid and binding against all parties having claims of any kind in tort, contract, or otherwise against the defaulting unit of local government, irrespective of whether such parties have notice. Under any such interception, a defaulting unit of local government may bind itself to impose rates, charges, or taxes to the fullest extent permitted by applicable law. Any ordinance, resolution, trust agreement, or other instrument by which a lien is created shall be filed in the records of the Agency.
The State Treasurer, the State Comptroller, the Department of Revenue, the Department of Transportation, and any county official charged with collecting and disbursing property taxes shall deposit or cause to be deposited any amount of grants or other revenues or taxes expected to be received by the defaulting unit of local government from that official or entity that has been pledged to the defaulting unit of local government, directly into a designated escrow account established by the Agency at a trust company or bank having trust powers, unless otherwise prohibited by law. The court order authorizing that disposition shall, within 10 days after issuance, be filed with the official or entity with custody of the garnished grants or other revenues or taxes.
