Oregon Revised Statutes Probate Law § 114.285

The naming or appointment of any person as personal representative does not discharge any claim which the decedent had against that person. The claim shall be included in the inventory. If the person agrees to act as personal representative, the person is liable for the claim as for so much money in the hands of the person at the time the claim becomes due and payable; otherwise the person is liable for the claim as any other debtor of the decedent.
