Oregon Revised Statutes Public Lands § 275.220

(1) In case of breach of condition or other default in performance of a land sale contract made pursuant to ORS 275.190 or 275.200, the governing body of a county may, by order made and entered in its records, declare the breach or default and cancel the land sale contract or enter into a new purchase agreement in writing. If the land sale contract is canceled and the holder is found within the county, a certified copy of the order shall be served as a summons is served by the sheriff upon the holder of the canceled land sale contract. If the land sale contract is canceled and the holder is not found within the county, a certified copy of the order shall be served by mailing it to the holder by registered mail or by certified mail with return receipt at the last-known address of the holder. Return of such service shall be made upon such copy of order.

(2) Within 20 days after the service of the order of cancellation upon the holder, the holder of the canceled land sale contract may appeal from the order to the circuit court for the county in which the land is located. The circuit court shall try the appeal as an action not triable by right to a jury. If appeal is not taken or if it results, upon trial, in an affirmance of the order of cancellation, the order becomes absolute and the real property forfeited may be sold without notice.

(3) In addition to the remedy for breach or default of a land sale contract under this section, a county may pursue any other remedy provided by law for breach or default of a land sale contract including, but not limited to, the remedy provided by ORS 93.905 to 93.940.

(4) In case of breach of condition or other default in performance of a purchase agreement other than a land sale contract, a county may pursue any remedy provided by law for breach or default of a purchase agreement other than a land sale contract.
