Code Civ. Proc., § 372

(a) (1) When a minor, a person who lacks legal capacity to make decisions, or a person for whom a conservator has been appointed is a party, that person shall appear either by a guardian or conservator of the estate or by a guardian ad litem appointed by the court in which the action or proceeding is pending, or by a judge thereof, in each case.

(2) (A) A guardian ad litem may be appointed in any case when it is deemed by the court in which the action or proceeding is prosecuted, or by a judge thereof, expedient to appoint a guardian ad litem to represent the minor, person who lacks legal capacity to make decisions, or person for whom a conservator has been appointed, notwithstanding that the person may have a guardian or conservator of the estate and may have appeared by the guardian or conservator of the estate.

(B) If application is made for appointment of a guardian ad litem for a person described in paragraph (1), and that person has a guardian or conservator of the estate, the application may be granted only if all of the following occur:

(i) The applicant gives notice and a copy of the application to the guardian or conservator of the estate upon filing the application.

(ii) The application discloses the existence of a guardian or conservator of the estate.

(iii) The application sets forth the reasons why the guardian or conservator of the estate is inadequate to represent the interests of the proposed ward in the action.

(C) The guardian or conservator of the estate shall have five court days from receiving notice of the application to file any opposition to the application.

(3) The guardian or conservator of the estate or guardian ad litem so appearing for any minor, person who lacks legal capacity to make decisions, or person for whom a conservator has been appointed shall have power, with the approval of the court in which the action or proceeding is pending, to compromise the same, to agree to the order or judgment to be entered therein for or against the ward or conservatee, and to satisfy any judgment or order in favor of the ward or conservatee or release or discharge any claim of the ward or conservatee pursuant to that compromise. Money or other property to be paid or delivered pursuant to the order or judgment for the benefit of a minor, person lacking legal capacity to make decisions, or person for whom a conservator has been appointed shall be paid and delivered as provided in Chapter 4 (commencing with Section 3600) of Part 8 of Division 4 of the Probate Code.

(4) Where reference is made in this chapter to “a person who lacks legal capacity to make decisions,” the reference shall be deemed to include all of the following:

(A) A person who lacks capacity to understand the nature or consequences of the action or proceeding.

(B) A person who lacks capacity to assist the person’s attorney in the preparation of the case.

(C) A person for whom a conservator may be appointed pursuant to Section 1801 of the Probate Code.

(5) Nothing in this section, or in any other provision of this code, the Civil Code, the Family Code, or the Probate Code is intended by the Legislature to prohibit a minor from exercising an intelligent and knowing waiver of the minor’s constitutional rights in a proceeding under the Juvenile Court Law (Chapter 2 (commencing with Section 200) of Part 1 of Division 2 of the Welfare and Institutions Code).

(b) (1) Notwithstanding subdivision (a), a minor 12 years of age or older may appear in court without a guardian, counsel, or guardian ad litem, for the purpose of requesting or opposing a request for any of the following:

(A) An injunction or temporary restraining order or both to prohibit harassment pursuant to Section 527.6.

(B) An injunction or temporary restraining order or both against violence or a credible threat of violence in the workplace pursuant to Section 527.8.

(C) A protective order pursuant to Division 10 (commencing with Section 6200) of the Family Code.

(D) A protective order pursuant to Sections 7710 and 7720 of the Family Code.

The court may, either upon motion or in its own discretion, and after considering reasonable objections by the minor to the appointment of specific individuals, appoint a guardian ad litem to assist the minor in obtaining or opposing the order, provided that the appointment of the guardian ad litem does not delay the issuance or denial of the order being sought. In making the determination concerning the appointment of a particular guardian ad litem, the court shall consider whether the minor and the guardian have divergent interests.

(2) For purposes of this subdivision only, upon the issuance of an order pursuant to paragraph (1), if the minor initially appeared in court seeking an order without a guardian or guardian ad litem, and if the minor is residing with a parent or guardian, the court shall send a copy of the order to at least one parent or guardian designated by the minor, unless, in the discretion of the court, notification of a parent or guardian would be contrary to the best interest of the minor. The court is not required to send the order to more than one parent or guardian.

(c) (1) Notwithstanding subdivision (a), a minor may appear in court without a guardian ad litem in the following proceedings if the minor is a parent of the child who is the subject of the proceedings:

(A) Family court proceedings pursuant to Part 3 (commencing with Section 7600) of Division 12 of the Family Code.

(B) Dependency proceedings pursuant to Chapter 2 (commencing with Section 200) of Part 1 of Division 2 of the Welfare and Institutions Code.

(C) Guardianship proceedings for a minor child pursuant to Part 2 (commencing with Section 1500) of Division 4 of the Probate Code.

(D) Any other proceedings concerning child custody, visitation, or support.

(2) If the court finds that the minor parent is unable to understand the nature of the proceedings or to assist counsel in preparing the case, the court shall, upon its own motion or upon a motion by the minor parent or the minor parent’s counsel, appoint a guardian ad litem.

(d) Before a court appoints a guardian ad litem pursuant to this chapter, a proposed guardian ad litem shall disclose both of the following to the court and all parties to the action or proceeding:

(1) Any known actual or potential conflicts of interest that would or might arise from the appointment.

(2) Any familial or affiliate relationship the proposed guardian ad litem has with any of the parties.

(e) If a guardian ad litem becomes aware that a potential conflict of interest has become an actual conflict of interest or that a new potential or actual conflict of interest exists, the guardian ad litem shall promptly disclose the conflict of interest to the court.
