ORS § 117.065
Upon proof that the absentee is alive, letters theretofore granted shall be revoked. Acts of the personal representative before revocation of letters are as valid as though the letters had not been revoked, but after revocation the personal representative has no further power in the capacity of personal representative except as provided in this section. The personal representative shall pay claims allowed and proved. Within 30 days after letters are revoked under this section, the personal representative must file an account of administration for the period of time before revocation of letters and transfer any property in the possession of the personal representative to the person for whose estate the personal representative acted or to the authorized agent of that person.
