Oregon Revised Statutes Domestic Relations § 107.449

(1) Upon motion of a party to a proceeding under ORS 107.135 (1) that is not otherwise covered under the provisions of ORS 25.100 (1), based upon convenience of the parties, the court that has entered the original judgment may order that the matter be transferred to an auxiliary circuit court where either party resides for the purpose of hearing the matter.

(2) Upon entry of an order under this section and payment by the moving party of the copying and certification costs, the clerk of the court that ordered the transfer shall transmit certified copies of the files, records and prepared transcripts of testimony in the original proceeding to the clerk of the court receiving the matter. Upon receipt of such certified copies, the circuit court of the county to which such certified copies have been transmitted shall have jurisdiction the same as if it were the court that made and entered the original order or judgment.

(3) The only court having jurisdiction to modify any provision of the original order or judgment is the court having original jurisdiction of the cause in which such order or judgment was entered or the circuit court of the county in which either party resides if that court has received the certified copies referred to in subsection (2) of this section. The provisions of ORS 25.100 (2) to (4) shall apply to all records maintained and orders issued in the auxiliary proceeding.
