How do I get legal guardianship of a child in California?

Quick answer

You file a probate guardianship petition with the superior court, generally in the county where the child lives, give notice to the child’s parents and close relatives, and a judge decides after a court investigation. A relative or another person can file, and so can the child if 12 or older. A guardianship gives an adult who is not the child’s parent responsibility for the child; it is not a custody case between parents.

What the law says

Probate Code section 1510(a): “A relative or other person on behalf of the minor, or the minor if 12 years of age or older, may file a petition for the appointment of a guardian of the minor.” Under section 1510(b), the petition must “state that the appointment is necessary or convenient.”

Section 1514(a): “Upon hearing of the petition, if it appears necessary or convenient, the court may appoint a guardian of the person or estate of the proposed ward or both.” In appointing a guardian of the person, section 1514(b)(1) applies the Family Code custody rules that begin at sections 3020 and 3040, and section 1514(b)(2) says that, except as provided in sections 1510.1 and 2105, a parent may not be appointed guardian of the person of their own child.

The courts’ self-help guide: “A guardianship is when an adult, who is not a child's parent, is legally responsible for the child's care because the child's parent is unable to care for them.” It adds that the court stays involved until the guardianship ends.

What to do next

The self-help guide’s list of starting forms includes the Petition for Appointment of Guardian of the Person (form GC-210(P)), or form GC-210 if you also ask to manage the child’s estate; a Child Information Attachment (form GC-210(CA)) and an Indian Child Inquiry Attachment (form ICWA-010(A)) for each child; the UCCJEA declaration (form FL-105/GC-120); a Confidential Guardian Screening Form (form GC-212) from each proposed guardian; the Notice of Hearing (form GC-020), with a Proof of Personal Service (form GC-020(P)) for relatives who must be served in person; the Duties of Guardian (form GC-248), signed by every proposed guardian; and the Letters of Guardianship (form GC-250) and the order appointing a guardian (form GC-240), with only the caption filled in. Some courts also require a Consent of Proposed Guardian (form GC-211). It says a decision takes at least a month, usually longer, and that in an emergency you can also ask to be appointed temporary guardian, but not by itself.
