Oregon Revised Statutes Procedure in Civil Proceedings § 18.627

(1) Except as otherwise provided by law, the first writ of garnishment delivered to a garnishee has priority over all other writs delivered to the garnishee for the same debtor. A garnishee shall make payments or deliver property under a subsequently delivered writ only if there is garnishable property of the debtor remaining in the garnishee's possession, control or custody after complying with the first writ delivered to the garnishee.

(2) If a debtor earns wages from a garnishee during the period that a writ of garnishment is in effect under ORS 18.625, the garnishee shall make payments under the first writ delivered to the garnishee until the expiration of the period of time specified in ORS 18.625, and shall thereafter make payments on subsequently delivered writs in the order in which they were delivered to the garnishee as long as each writ continues to be effective under ORS 18.625. Any delay in payment under a writ by reason of this subsection does not affect the expiration of the writ's effect at the time specified in ORS 18.625. If the first writ does not garnish all wages of the debtor that are not exempt from execution, the garnishee shall make concurrent payment on a subsequently delivered writ of the balance of the wages that are not exempt from execution.

(3) If a garnishee pays wages to a debtor and the garnishee receives another writ of garnishment during the period that a writ is in effect under ORS 18.625, the garnishee shall note those facts on the garnishee response and indicate the date on which the previous writ will expire.

(4) A subsequent writ of garnishment issued on behalf of the same creditor against the same debtor and delivered to the same garnishee during the period that a previous writ is effective under ORS 18.625 acts only to garnish property of the debtor other than wages.
