Oregon Revised Statutes Procedure in Civil Proceedings § 18.736

(1) If a garnishee that employs a debtor is required to make any payment under a writ of garnishment by reason of wages payable to the debtor, the garnishee may collect a $2 processing fee for each week of wages, or fraction of a week of wages, for which a payment is made under the provisions of ORS 18.735. The processing fee must be collected after the last payment is made under the writ. The fee shall be withheld from the wages of the debtor, and is in addition to the amounts withheld for payment to the garnishor under the writ or under any other writ delivered to the garnishee.

(2) The fee provided for in this section may not be collected if withholding of the fee would reduce the debtor's net disposable income below the minimum amounts prescribed by ORS 18.385.
