Oregon Revised Statutes Mortgages and Liens § 87.282

(1) That the lien debtor, by conspicuous words in a writing executed by or on behalf of the lien debtor before filing of the petition under ORS 87.272 or by handwriting of the lien debtor or the lien debtor's agent executed before filing of the petition under ORS 87.272, has declared substantially that the lien debtor is aware of the right to notice and hearing on the question of the probable validity of the underlying lien claim before the lien debtor can be deprived of the property in the possession or control of the lien debtor or in the possession or control of another and that the lien debtor waives that right and agrees that the lien claimant, or one acting on behalf of the lien claimant, may take possession or control of the chattel subject to the lien without first giving notice and opportunity for hearing on the probable validity of the underlying lien claim;

(2) That there is no reason to believe that the waiver or agreement is invalid; and

(3) That the lien debtor has voluntarily, intelligently and knowingly waived that right.
