Oregon Revised Statutes Chapter 36 § 36.458 — When

When written communication considered to have been received. (1) Unless otherwise agreed by the parties: (a) Any written communication is considered to have been received if it is delivered to the addressee personally or if it is delivered at the place of business, habitual residence or mailing address of the addressee. If none of these can be found after making a reasonable inquiry, a written communication is considered to have been received if it is sent to the addressee’s last-known place of business, habitual residence or mailing address by registered letter or by any other means which provides a record of the attempt to deliver it; and (b) The communication is considered to have been received on the day it is so delivered. (2) The provisions of this section do not apply to communications in court proceedings. [1991 c.405 §6]
