In civil actions, the designation of a known party by a name other than the party's true name shall be allowed only upon an order of the court. If ordered, the designation of such party shall be by use of such party's initials or a pseudonym other than "Jane Doe" or "John Doe". The name "Jane Doe" or "John Doe" is reserved for a party whose identity is unknown and the party is being designated as provided in ORCP 20H. Petitions to designate known parties by pseudonyms must be filed conventionally. Please see SLR 2.501.
