No collection agency that collects child support payments shall (i) impose a charge or fee, including costs, for collection of a current child support payment, (ii) fail to apply collections to current support as specified in the order for support before applying collection to arrears or other amounts, or (iii) designate a current child support payment as arrears or other amount owed. In all circumstances, the collection agency shall turn over to the obligee all support collected in a month up to the amount of current support required to be paid for that month.
As to any fees or charges, including costs, retained by the collection agency, that agency shall provide documentation to the obligee demonstrating that the child support payments resulted from the actions of the agency.
After collection of the total amount or arrearage, including statutory interest, due as of the date of execution of the collection contract, no further fees may be charged.
Without prejudice to the determination by the Department of the appropriate rate through administrative rule, a collection agency shall impose a fee of not more than 29% of the amount of child support actually collected by the collection agency subject to the provisions of subsection (a-5). This interim rate is based upon the March 2002 General Account Office report "Child Support Enforcement", GAO-02-349. This rate shall apply until a fee rate is established by administrative rule.
