Upon motion of the judgment creditor, upon notice to the judgment debtor, where it is shown that the judgment debtor is receiving or will receive money from any source, or is attempting to impede the judgment creditor by rendering services without adequate compensation, the court shall order that the judgment debtor make specified installment payments to the judgment creditor. Notice of the motion shall be served on the judgment debtor in the same manner as a summons or by registered or certified mail, return receipt requested. In fixing the amount of the payments, the court shall take into consideration the reasonable requirements of the judgment debtor and his dependents, any payments required to be made by him or deducted from the money he would otherwise receive in satisfaction of other judgments and wage assignments, the amount due on the judgment, and the amount being or to be received, or, if the judgment debtor is attempting to impede the judgment creditor by rendering services without adequate compensation, the reasonable value of the services rendered.
