Oregon Revised Statutes Domestic Relations § 106.060

A marriage license shall not be issued without the written consent of the parent or guardian, if any, of an applicant who is less than 18 years of age, nor in any case unless the parties are each of an age, as provided in ORS 106.010, capable of contracting marriage. If either party under 18 years of age has no parent or guardian resident within this state and either party has resided within the county in which application is made for the six months immediately preceding the application, the license may issue, if otherwise proper, without the consent of the nonresident parent or guardian.
