ORS § 20.320
Costs or disbursements shall not be allowed in the Supreme Court or Court of Appeals to a party unless the party serves on the adverse party or the adverse party's attorney, and files with the State Court Administrator, a statement certified under ORCP 17 showing with reasonable certainty all costs and disbursements claimed by the party. The statement must be accompanied by proof of service on all adverse parties, and must be filed within 21 days from the date of the court's decision, or within such further time as may be allowed by the court. The total of the items included in the statement of costs and disbursements thus filed, with the exception of items or amounts not allowed by law or by rules of the Supreme Court or Court of Appeals, shall be entered by the administrator as a part of the appellate judgment, in favor of the party entitled to the costs and disbursements, unless an adverse party within 14 days from date of service of the statement serves and files objections to the statement. The filing or appearance fee and the prevailing party fee under ORS 20.190(1) shall be awarded by the court without the filing of a statement of costs and disbursements.
