ORS § 33.610
In the administration of a decedent's estate, or whenever the assets of any person, partnership or corporation are being administered in receivership or any liquidation proceedings, or under an assignment for the benefit of creditors, the value of securities held by secured creditors shall be determined by converting the same into money according to the terms of the agreement pursuant to which the securities were delivered to the creditors, or by the creditors and the person or official liquidating the assets by agreement, arbitration, compromise or litigation. Where the proceedings are in court, the determination shall be subject to the control or decision of the court. If, under an assignment for the benefit of creditors, the secured creditor and the assignee cannot, by agreement, arbitration or compromise, determine the value, either the assignee or the creditor may apply to a court of competent jurisdiction in the place of residence of the assignee for determination of the value by declaratory judgment, or otherwise. In all cases, the amount of the determined value shall be credited upon the secured claim and a general or unsecured creditor's dividend shall be paid only on the uncredited balance, if any, of the claim. Nothing contained in this section shall be construed to compel any creditor holding security to file a claim for participation in any such estate or proceeding, or to compel the creditor, if the creditor does not file a claim, to foreclose or realize upon the security of the creditor.
