Oregon Revised Statutes Procedure in Civil Proceedings § 18.752

(1) If a garnishee indicates in the garnishee response that the garnishee holds any property described in ORS 18.750, the garnishee must hold the garnished property, or a portion of the property sufficient to satisfy the garnishment, for a period of 30 days after the garnishee delivers the garnishee response to the court administrator for the court specified in the writ of garnishment as having authority over the writ, unless the sheriff or the garnishor notifies the garnishee that the garnishment is released or terminated. If the sheriff contacts the garnishee during the 30-day period, the garnishee shall deliver the property to the sheriff or take such other action as may be specified in the notice given to the garnishee under ORS 18.755 (4).

(2) If the garnishee is not contacted by the sheriff before the end of the 30-day period provided for in subsection (1) of this section, the garnishment is of no further force or effect with respect to the property and the garnishee may deal with the garnished property as if the writ had not been delivered to the garnishee.
