(2) A judgment debtor may not use a challenge to execution form to challenge execution on residential property of the debtor as defined by ORS 18.901 if the judgment creditor has obtained an order under ORS 18.904 authorizing the sale or if the judgment directs the sale or delivery of specific property.

(3) Any person other than a judgment debtor who has an interest in any property levied on by a sheriff may assert that interest by delivering a challenge to execution in the manner provided by subsection (4) of this section.

(4) A person may make a challenge to a writ of execution by completing the challenge to execution form provided in ORS 18.896, or a substantially similar form, and by delivering, in person or by first class mail, the original of the completed form to the court administrator for the court identified in the writ of execution and a copy of the challenge to the judgment creditor. Upon receiving a copy of the challenge, the judgment creditor shall promptly notify the sheriff of the challenge.

(5) A challenge to execution must be delivered in the manner provided by subsection (4) of this section within 30 days after the property is levied on as described in ORS 18.878 or before the property is sold on execution, whichever occurs first.
