Wyo. Stat. § 1-16-103

of law.

     (a) As used in this section "judgment by operation of law"
means a periodic payment or installment for child support or
maintenance which is unpaid on the date due and which has become
a judgment by operation of law pursuant to W.S. 14-2-204.

     (b) Any judgment by operation of law which is not paid
within thirty-two (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 ten percent (10%) of the
amount of the judgment by operation of law.

     (c) 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 ten (10) days after seizure
of his property under execution.

     (d) This section shall apply only to judgments by
operation of law arising on or after July 1, 1990.
