Welf. & Inst. Code, § 316.1

(a) Upon his or her appearance before the court, each parent or guardian shall designate for the court his or her permanent mailing address. The court shall advise each parent or guardian that the designated mailing address will be used by the court and the social services agency for notice purposes unless and until the parent or guardian notifies the court or the social services agency of a new mailing address in writing.

(b) Upon his or her appearance before the court, each party who consents to electronic service pursuant to Section 212.5 shall designate for the court his or her electronic service address. The court shall advise each party that the electronic service address will be used by the court and the social services agency for purposes of providing notice pursuant to Sections 291, 292, 293, 294, 295, 297, and 342, unless and until the party notifies the court or the social services agency of a new electronic service address in writing or unless the party withdraws consent to electronic service.

(c) A party’s decision not to consent to electronic service and designate an electronic service address, as authorized in subdivision (b), does not preclude the use of electronic means to send information regarding the date, time, and place of a juvenile court hearing, provided that the confidentiality requirement of paragraph (7) of subdivision (a) of Section 212.5 is met. The party does not need to designate an electronic service address in order for the information to be provided electronically. However, information shared, as described in this subdivision, shall only be in addition to, and not in lieu of, any required service or notification made in accordance with any other law governing how that service or notification is provided.
