Oregon Revised Statutes Domestic Relations § 107.560

(1) A petition may be filed under ORS 107.550 whether or not a domestic relations suit in which the spouses are parties has been commenced. Except as provided in subsection (2) of this section, when a petition for conciliation jurisdiction is filed no trial or hearing on the merits of a domestic relations suit between the parties shall be had until after the expiration of 45 days from the filing of the petition; provided, however, that during this period the court may use its full equity powers to protect and preserve the rights of the spouses.

(2) The court may, in its discretion, waive the 45-day period as prescribed by subsection (1) of this section upon stipulation of the parties or upon written motion supported by affidavit setting forth facts which satisfy the court that such waiver is warranted.
