Oregon Revised Statutes Mortgages and Liens § 87.460

(1) When an attorney claims a lien under ORS 87.445, if the judgment is for the possession, award or conveyance of real property, the attorney must file a notice of claim of lien not later than six months after entry of the judgment and disposition of any appeal of the judgment. The notice shall be filed with the recording officer of the county in which the real property, or any part of it, is situated. The recording officer of a county shall record the notices filed under this section in a book that shall be indexed in the same manner as the record of deeds and mortgages.

(2) Except as provided in subsection (3) of this section, a lien under ORS 87.445 upon a judgment for the possession, award or conveyance of real property must be foreclosed in the manner provided in ORS chapter 88, not later than one year after the notice of claim of lien is filed under subsection (1) of this section.

(3) An attorney and the client of the attorney may, by agreement, in writing, extend the period of time within which a lien created by ORS 87.445 must be foreclosed to two years after the notice of claim of lien is filed. An agreement to extend a foreclosure period under this subsection shall contain the time and place of the filing of the notice of claim of lien by the attorney and shall be filed with the recording officer with whom the notice of claim of lien was filed.
