Oregon Revised Statutes Procedure in Civil Proceedings § 18.735

(1) The garnishee must make an initial payment when the garnishee next pays any wages to the debtor. The payment must be for all wages that were owing to the debtor on the date that the writ was delivered to the garnishee, and all amounts that are being paid to the debtor for work performed after the writ was delivered and before issuance of the paycheck. The garnishee must compute the amount of wages subject to garnishment using the wage exemption calculation form provided by ORS 18.840 and must mail a copy of the completed form along with the first payment under the writ.

(2) Unless the writ of garnishment is satisfied or released, the garnishee must make subsequent payments under the writ whenever the garnishee makes any payment of wages to the debtor during the period specified in ORS 18.625. Each time there is any change in the debtor's pay period or any change in the amount paid to the debtor during the debtor's pay period, the garnishee must complete a new wage exemption calculation form and mail a copy of the completed form along with the payment.

(3) Unless the writ of garnishment is satisfied or released sooner, the garnishee must make a final payment under the writ when the garnishee next makes a payment of wages to the debtor after the writ expires under the provisions of ORS 18.625. The payment must be for all wages that were owing to the debtor on the date that the writ expires. The garnishee must complete a new wage exemption calculation form and mail a copy of the completed form along with the final payment.
