Oregon Revised Statutes Probate Law § 114.537

(1) If a claiming successor or other person who is eligible to file an affidavit under ORS 114.515 is aware that the decedent was the sole lessee or the last surviving lessee of a safe deposit box at the time of the decedent's death, the claiming successor or other person may not file an affidavit under ORS 114.515 until the person requests an inventory of the box under ORS 708A.655, if the lessor of the box is an Oregon operating institution as defined in ORS 706.008, or under ORS 723.844, if the lessor of the box is a credit union as defined in ORS 723.008. Upon receiving the request, the lessor of the box shall cause an inventory of the contents of the box to be made. The lessor shall retain the original inventory in the box and shall provide a copy of the inventory to the person requesting the inventory. The person requesting the inventory shall take the contents of the box into consideration in determining whether the estate of the decedent is within the limits prescribed by ORS 114.515 (2). If an affidavit under ORS 114.515 is filed by the person, the value of the contents of the box shall be stated in the affidavit.

(2) If a person who has filed an affidavit under ORS 114.515 becomes aware after the filing of the affidavit that the decedent was the sole lessee or the last surviving lessee of a safe deposit box at the time of the decedent's death, the person shall promptly request an inventory of the box under ORS 708A.655, if the lessor of the box is an Oregon operating institution as defined in ORS 706.008, or under ORS 723.844, if the lessor of the box is a credit union as defined in ORS 723.008. Upon receiving the request, the lessor of the box shall cause an inventory of the contents of the box to be made. The lessor shall retain the original inventory in the box and shall provide a copy of the inventory to the person requesting the inventory. If the estate of the decedent remains within the limits prescribed by ORS 114.515 (2) after consideration of the value of the contents of the box, the person shall file an amended affidavit under ORS 114.515. Upon providing the lessor of the box with a certified copy of the amended affidavit, the lessor shall allow the person to take possession of the contents of the box. If the estate of the decedent exceeds the limits prescribed by ORS 114.515 (2) after consideration of the value of the contents of the box, the person may not file an amended affidavit under ORS 114.515 and shall file notice with the court that the estate of the decedent is not subject to ORS 114.505 to 114.560 and shall serve a copy of the notice on the lessor of the box. The lessor of the box shall thereafter deliver the contents of the box to the personal representative for the decedent, or to such other person as may be provided for under the terms of the lease of the box.
