Oregon Revised Statutes Probate Law § 114.345

Property sold, mortgaged or leased by a personal representative is subject to liens and encumbrances against the decedent or the estate of the decedent, but is not subject to rights of creditors of the decedent or liens or encumbrances against the heirs or devisees of the decedent. The filing and allowance of a claim in an estate proceeding does not make the claimant a secured creditor.
