Any judgment by operation of law which is not paid within 32 calendar days from the date the judgment by operation of law arises is subject to an automatic late payment penalty in an amount equal to 10% of the amount of the judgment by operation of law.In order to recover penalties assessed under subsection (b) of this section, the obligee shall file with the clerk of court a sworn affidavit setting forth the payment history resulting in assessment of any penalty and a computation of all penalties claimed to be due and owing. It shall not be the responsibility of the clerk to compute the amount of the penalties due and owing. If the obligor disputes the payment history or penalty computation as stated in the obligee’s sworn affidavit, the obligor shall file with the clerk of court a written request for a hearing within 10 days after seizure of his property under execution. This section shall apply only to judgments by operation of law arising on or after July 1, 1990.
