Cal. CCP § 376

(a) The parents of a legitimate unmarried minor child, acting jointly, may maintain an action for injury to the child caused by the wrongful act or neglect of another. If either parent fails on demand to join as plaintiff in the action or is dead or cannot be found, then the other parent may maintain the action. The parent, if living, who does not join as plaintiff shall be joined as a defendant and, before trial or hearing of any question of fact, shall be served with summons either in the manner provided by law for the service of a summons in a civil action or by sending a copy of the summons and complaint by registered mail with proper postage prepaid addressed to that parent’s last known address with request for a return receipt. If service is made by registered mail, the production of a return receipt purporting to be signed by the addressee creates a rebuttable presumption that the summons and complaint have been duly served. The presumption established by this section is a presumption affecting the burden of producing evidence. The respective rights of the parents to any award shall be determined by the court.

(b) A parent may maintain an action for such an injury to his or her illegitimate unmarried minor child if a guardian has not been appointed. Where a parent who does not have care, custody, or control of the child brings the action, the parent who has care, custody, or control of the child shall be served with the summons either in the manner provided by law for the serving of a summons in a civil action or by sending a copy of the summons and complaint by registered mail, with proper postage prepaid, addressed to the last known address of that parent, with request for a return receipt. If service is made by registered mail, the production of a return receipt purporting to be signed by the addressee creates a rebuttable presumption that the summons and complaint have been duly served. The presumption established by this section is a presumption affecting the burden of producing evidence. The respective rights of the parents to any award shall be determined by the court.

(c) The father of an illegitimate child who maintains an action under this section shall have acknowledged in writing prior to the child’s injury, in the presence of a competent witness, that he is the father of the child, or, prior to the child’s injury, have been judicially determined to be the father of the child.

(d) A parent of an illegitimate child who does not maintain an action under this section may be joined as a party thereto.

(e) A guardian may maintain an action for such an injury to his or her ward.

(f) An action under this section may be maintained against the person causing the injury. If any other person is responsible for the wrongful act or neglect, the action may also be maintained against the other person. The death of the child or ward does not abate the parents’ or guardian’s cause of action for the child’s injury as to damages accruing before the child’s death.

(g) In an action under this section, damages may be awarded that, under all of the circumstances of the case, may be just, except that:

(1) In an action maintained after the death of the child, the damages recoverable are as provided in Section 377.34.

(2) Where the person causing the injury is deceased, the damages recoverable in an action against the decedent’s personal representative are as provided in Section 377.42.

(h) If an action arising out of the same wrongful act or neglect may be maintained pursuant to Section 377.60 for wrongful death of a child described in this section, the action authorized by this section may be consolidated therewith for trial as provided in Section 1048.
