The Oregon Rules of Civil Procedure apply to proceedings under this section. Any party to a proceeding under this section may request that the pleadings and records in the proceeding be sealed.

(2) A surviving spouse may withdraw a petition filed under this section at any time before entry of a judgment on the petition.
