Oregon Revised Statutes Courts of Record; Court Officers; Juries § 9.310

An attorney is a person authorized to represent a party in the written proceedings in any action, suit or proceeding, in any stage thereof. An attorney, other than the one who represents the party in the written proceedings, may also represent a party in court, or before a judicial officer, in which case the attorney is known as counsel, and the authority of the attorney is limited to the matters that transpire in the court or before such officer at the time.
