prepare a certification that states the amount of the judgment remaining unsatisfied as of the last calendar day of each full calendar quarter for which the wage deduction order continues in effect.
        (2) The certification shall be mailed or delivered to
    
the employer by the judgment creditor or his or her attorney within 15 days after the end of each calendar quarter for which the wage deduction order continues in effect. The employer shall hand deliver or mail by first class mail a copy of the certification to the judgment debtor at the judgment debtor's last known address.
