Oregon Revised Statutes Crimes and Punishments § 161.675

(1) When a defendant, as a part of a sentence or as condition of probation or suspension of sentence, is required to pay a sum of money for any purpose, the court may order payment to be made immediately or within a specified period of time or in specified installments. If a defendant is sentenced to a term of imprisonment, any part of the sentence that requires the payment of a sum of money for any purpose is enforceable during the period of imprisonment if the court expressly finds that the defendant has assets to pay all or part of the amounts ordered.

(2) When a defendant whose sentence requires the payment of a sum of money for any purpose is also sentenced to probation or imposition or execution of sentence is suspended, the court may make payment of the sum of money a condition of probation or suspension of sentence.

(3) When a defendant is sentenced to probation or imposition or execution of sentence is suspended and the court requires as a part of the sentence or as a condition of the probation or suspension of sentence that the defendant pay a sum of money in installments, the court, or the court clerk or parole and probation officer if so ordered by the court, shall establish a schedule of payments to satisfy the obligation. A schedule of payments shall be reviewed by the court upon motion of the defendant at any time, so long as the obligation remains unsatisfied.
