Amending an Oregon pleading: one free amendment, and what it means for a party already in default

Oregon procedure · Last verified August 17, 2026

Oregon's amendment rule follows the familiar pattern and then adds a paragraph most systems leave to case law: what happens to a party who is already in default when the pleadings change.

One amendment as of course

ORCP 23 A:

A pleading may be amended by a party once as a matter of course at any time before a responsive pleading is served or, if the pleading is one to which no responsive pleading is permitted, the party may so amend it at any time within 20 days after it is served. Otherwise a party may amend the pleading only by leave of court or by written consent of the adverse party; and leave shall be freely given when justice so requires.

Two windows, as in FRCP 15(a)(1) and Mass. R. Civ. P. 15(a) — but note what Oregon does not do. The federal rule sets a 21-day outer limit even where a responsive pleading is required. Oregon's first window runs until the responsive pleading is actually served, with no fixed number of days attached.

A defendant who takes 29 of their 30 days to answer leaves the plaintiff free to amend as of course for all of that time.

The default provision

The part of ORCP 23 A that has no federal counterpart:

Whenever an amended pleading is filed, it shall be served upon all parties who are not in default, but as to all parties who are in default or against whom a default previously has been entered, judgment may be rendered in accordance with the prayer of the original pleading served upon them; and neither the amended pleading nor the process thereon need be served upon such parties in default unless the amended pleading asks for additional relief against the parties in default.

Three consequences, and they cut both ways.

A defaulting party is frozen at the original prayer. Judgment against them is rendered on what the original pleading asked for, not on an expanded amended version.

They need not be re-served with the amendment.

Unless the amendment asks for more. If the amended pleading seeks additional relief against a defaulted party, it must be served on them — which reopens their opportunity to respond to the new demand.

This is a meaningful protection. In systems without such a provision, whether an amendment resets a defaulting party's position is a case-law question; Oregon answers it in the rule.

Amendments to conform to the evidence

ORCP 23 B covers two situations.

Issues tried by consent. "When issues not raised by the pleadings are tried by express or implied consent of the parties, they shall be treated in all respects as if they had been raised in the pleadings." An amendment to conform may be made on motion of any party "at any time, even after judgment; but failure so to amend does not affect the result of the trial of these issues."

Objection at trial. If evidence is objected to on the ground that it is not within the issues made by the pleadings, "the court may allow the pleadings to be amended when the presentation of the merits of the action will be subserved thereby and the objecting party fails to satisfy the court that the admission of such evidence would prejudice such party in maintaining an action or defense upon the merits."

The burden sits with the objecting party, as it does under FRCP 15(b)(1) and O.C.G.A. § 9-11-15(b).

Relation back

ORCP 23 C provides that whenever the claim or defense asserted in the amended pleading arose out of the conduct, transaction or occurrence set forth or attempted to be set forth in the original pleading, the amendment relates back to the date of the original pleading.

For an amendment changing the party against whom a claim is asserted, the rule adds the familiar conditions — notice such that the party will not be prejudiced in maintaining a defense, and knowledge that but for a mistake concerning identity the action would have been brought against them — within the period provided for commencing the action.

Supplemental pleadings

ORCP 23 E permits the court, on motion and reasonable notice and on just terms, to allow a party to serve a supplemental pleading setting out transactions, occurrences or events that have happened since the date of the pleading being supplemented.

As elsewhere, a supplemental pleading always requires a motion — the as-of-course right in ORCP 23 A applies to amendments only.

Where the deadline actually bites

Oregon has no scheduling-order cutoff written into ORCP 23 of the sort FRCP 16(b)(4) imposes federally. The practical limits after the as-of-course window are the "freely given when justice so requires" standard and prejudice to the other side.

But note the interaction with summary judgment: ORCP 47 C requires a motion to be served and filed at least 60 days before trial, and an amendment that changes the claims late in a case can leave a summary-judgment motion addressed to superseded pleadings.

A short checklist

  1. Check whether a responsive pleading has been served. Until it has, you can amend once without leave and without a day count.
  2. Serve the amendment on everyone not in default.
  3. If the amendment asks for more against a defaulted party, serve them too — ORCP 23 A requires it, and skipping it caps your judgment at the original prayer.
  4. Get leave or written consent after the first window; the standard is generous but the request is required.
  5. Watch the summary-judgment interaction — ORCP 47 C's 60-day rule doesn't move because you amended.
  6. If limitations are in play, ORCP 23 C governs relation back, and a party change has its own conditions.
