(1) Subject to RCW 11.96A.160, in all judicial proceedings under this title that require notice, the notice must be personally served on or mailed to all parties or the parties' legal or virtual representatives and to any other persons to whom notice may be required under applicable law at least twenty days before the hearing on the petition unless a different period is provided by statute or ordered by the court. The date of service shall be determined under the rules of civil procedure. Notwithstanding the foregoing, notice that is provided in an electronic transmission and electronically transmitted complies with this section if the party receiving notice has previously consented in a record delivered to the party giving notice to receiving notice by electronic transmission. Consent to receive notice by electronic transmission may be revoked at any time by a record delivered to the party giving notice. Consent is deemed revoked if the party giving notice is unable to electronically transmit two consecutive notices given in accordance with the consent.

(2) Proof of the service, mailing, or electronic delivery required in this section must be made by affidavit or declaration filed at or before the hearing.

(3) For the purposes of this title, the terms "electronic transmission" and "electronically transmitted" have the same meaning as set forth in RCW 23B.01.400.
