ORS § 52.560
If it appears on the trial of any cause before a justice of the peace from the evidence of either party, or from the pleadings, that the title to real property is in question, which title is disputed by the other party, the justice shall immediately make an entry thereof in the docket of the justice and cease all further proceedings in the cause. The justice shall certify and return to the circuit court of the county a transcript of all the entries made in the docket of the justice relating to the case, together with all the process and other papers relating to the action, in the same manner and within the same time as upon an appeal. Thereupon the circuit court shall proceed in the cause to final judgment and execution in the same manner as if the action had been originally commenced therein, and disbursements shall abide the event of the action.
