ORS § 96.010
Whenever there is a fence that is in all respects such as a good husbandman ought to keep on the line of any land, and the person owning or holding a lease for one or more years of the land adjoining thereto makes or has an enclosure on the opposite side of such fence, so that such fence answers the purpose of enclosing the latter's field, meadow, lot or other enclosure, the latter shall pay the owner of such fence already erected, one-half of the value of so much thereof as serves as a partition fence, such value to be determined by the parties. If they cannot agree, the party aggrieved and entitled to compensation for constructing or repairing the partition fence shall be entitled to recover from the other in a civil action the value of one-half of such fence or half of the value of repairing it before any court having competent jurisdiction in the name of and for the use of the owner or lessee of such fence, together with disbursements and costs of action. The prevailing party shall also recover attorney fees at trial and on appeal, to be adjudged by the court.
