Rule 8.050.Judgment Modification Proceedings

Full Text of Rule 8.050
Plain-English Summary
A modification is not a letter to the judge. It opens with an order to show cause based on a motion supported by an affidavit or a declaration under penalty of perjury that sets out the factual basis for what you are asking. A judicial district can establish another procedure by supplementary local rule, so look there first. Whichever route you take, the initiating documents must contain a notice substantially in the form set out at ORCP 7, which is a rule of civil procedure rather than one of these trial court rules. That notice can stand alone or sit inside the order to show cause or the motion.
Service is formal. The initiating documents are served by delivering a certified copy of each document, and of the Uniform Support Declaration where one applies, in the manner necessary to obtain jurisdiction. Treat it with the care you would give service of an original petition.
When either party requests support, both parties complete and file a USD. The party seeking the modification files one with the motion and serves it. Once an order to show cause issues, the opposing party files a USD and serves it on the moving party within 30 days of service of the order to show cause, unless a supplementary local rule says otherwise. Both are completed as provided under UTCR 8.010(4), on the form at www.courts.oregon.gov/forms. Neither party needs a USD when the motion seeks to terminate child support solely because the child is no longer legally entitled to it. If the Division of Child Support or a district attorney child support office initiates or responds to a support modification, that office may file an affidavit covering the custodian, the children, public assistance, food stamp benefits, Medicaid, other known income of the physical custodian, and any special circumstances, in place of the USD.
One more requirement catches an easy mistake. A party who files an ex parte temporary custody or parenting time order under ORS 107.139 must also file a motion for permanent modification of custody, or already have one pending when the application is made. The emergency order is not the case; it rides on top of a modification you are pursuing.
Frequently Asked Questions
How do I start a modification case in Oregon?
File a motion supported by an affidavit or a declaration under penalty of perjury that sets out the factual basis, and obtain an order to show cause. A judicial district may establish a different procedure by supplementary local rule, so check the local rules for your district.
The initiating documents must carry a notice substantially in the form set out at ORCP 7, either as a separate document or written into the order to show cause or the motion.
Do I have to serve modification papers the same way as a new case?
Close to it. The rule requires you to serve the initiating documents by delivering a certified copy of each document, and of the Uniform Support Declaration if one applies, in the manner necessary to obtain jurisdiction.
When does the other party have to file a Uniform Support Declaration?
Once an order to show cause issues, the opposing party files a USD and serves it on the party seeking the modification within 30 days of service of that order, unless a supplementary local rule provides a different time.
The moving party files a USD with the motion itself.
Do we need a USD to stop child support for a child who is no longer entitled to it?
No. Neither party has to file a Uniform Support Declaration when the motion seeks to terminate child support solely because the child is no longer legally entitled to support.
If the motion asks for anything else along with that, the exception no longer covers you and the ordinary USD requirement returns.
I got an ex parte temporary custody order — what else do I have to file?
A motion for permanent modification of custody. Under this rule, a party who files an ex parte temporary custody or parenting time order under ORS 107.139 must file that motion or already have one pending at the time the application is made.
