Oregon Revised Statutes Property Rights and Transactions § 105.405

(1) The expenses of the referees, including those of a surveyor and assistants of the surveyor when employed, shall be ascertained and allowed by the court, and the amount thereof, together with the fees allowed by law to the referees, shall be paid by the plaintiff, and may be allowed as part of the costs of partition.

(2) The reasonable costs of partition, including reasonable attorney fees and disbursements, that are for services performed for the common benefit of all parties, shall be paid by the parties that will share in the lands divided in proportion to their respective interests therein, and shall be included and specified in the judgment. They shall be a lien on the several shares, and the judgment may be enforced by execution against the parties separately. When, however, a controversy arises between some of the parties only, the court may require the expense of such controversy to be paid by any of, or all, the parties thereto.
