Oregon Revised Statutes Insurance § 731.328

(1) Before an unauthorized insurer files or causes to be filed any pleading in any court action or any notice, order, pleading, or process in an administrative proceeding before the Director of the Department of Consumer and Business Services instituted against such person or insurer, by services made as provided in ORS 731.324, such insurer shall deposit with the clerk of the court in which such action is pending, or with the director in administrative proceedings before the director, cash or securities. The insurer may also file with such clerk or director a bond with good and sufficient sureties, to be approved by the clerk or director, or an irrevocable letter of credit issued by an insured institution, as defined in ORS 706.008, in an amount to be fixed by the court or director sufficient to secure the payment of any final judgment which may be rendered in such action or administrative proceeding.

(2) The director, in any administrative proceeding in which service is made as provided in ORS 731.324, may order such postponement as may be necessary to afford the defendant reasonable opportunity to comply with the provisions of subsection (1) of this section and to defend such action.

(3) Nothing in subsection (1) of this section shall be construed to prevent an unauthorized insurer from filing a motion to quash a writ or to set aside service thereof made in the manner provided in ORS 731.324.
