California Code, Family Code - FAM § 6385

(a) Proof of service of the protective order is not required for the purposes of Section 6380 if the order indicates on its face that both parties were personally present at the hearing at which the order was issued and that, for the purpose of Section 6384, no proof of service is required, or if the order was served by a law enforcement officer pursuant to Section 6383.

(b) The failure of the petitioner to provide the Department of Justice with the personal descriptive information regarding the person restrained does not invalidate the protective order.

(c) There is no civil liability on the part of, and no cause of action arises against, an employee of a local law enforcement agency, a court, or the Department of Justice, acting within the scope of employment, if a person described in Section 29825 of the Penal Code unlawfully purchases or receives or attempts to purchase or receive a firearm and a person is injured by that firearm or a person who is otherwise entitled to receive a firearm is denied a firearm and either wrongful action is due to a failure of a court to provide the notification provided for in this chapter.
