Guardianship Under the California Probate Code: A San Diego Overview

Guardianship of a minor is the legal mechanism that lets an adult who is not the parent make care and custody decisions for a child. In California, guardianship of a minor is primarily handled under the Probate Code (sections 1500 through 1611) in probate court, though juvenile guardianships arising out of dependency proceedings are handled separately under Welfare and Institutions Code section 360 in juvenile court.

This post walks through California probate guardianship of a minor: what it does, what it does not do, and how the case moves through San Diego Superior Court.

Guardianship of the person vs. the estate

California recognizes two kinds of guardianship of a minor, and they are decided separately.

Guardianship of the person gives the guardian authority to have the child in their care, to make decisions about the child's daily life, and to consent to medical care, education, and the child's normal activities. It is what most people mean when they say "guardianship."

Guardianship of the estate is separate and applies when a minor owns property (an inheritance, a settlement, a life-insurance proceed) that has to be managed until the minor turns eighteen. A guardian of the estate is a fiduciary who has to account to the court for the property.

The same adult can serve as guardian of both, or the two roles can go to different people. When large sums are involved, courts sometimes separate the roles.

What guardianship does not do

Guardianship is not adoption. It does not terminate the parent's rights or the parent-child relationship. Parents retain the ability to petition to terminate the guardianship on a change of circumstances, and the guardianship itself ends automatically when the minor turns eighteen (unless the ward is a nonminor dependent under special statutes).

Guardianship is also not the same as a family-law custody order. Custody orders in a family law case set the relationship between two parents. Guardianship orders in probate court set the relationship between a non-parent adult and a minor, usually because neither parent can care for the child right now, or because both parents consent.

When guardianship makes sense

The most common San Diego guardianship cases I see involve:

• A grandparent, aunt, or uncle raising a grandchild, niece, or nephew because the parents cannot (military deployment, incarceration, substance-use treatment, serious illness)
• A child living with a family friend whose parent has consented to the arrangement and the friend needs legal authority to enroll the child in school and consent to medical care
• A child whose parents have passed away, where a surviving family member is the intended caregiver
• A minor who has received a settlement or inheritance and needs a guardian of the estate to manage those funds

Filing the petition

A guardianship case starts with a Petition for Appointment of Guardian (Judicial Council form GC-210) filed in probate court. In San Diego County, probate guardianship cases are heard at the Central Courthouse downtown, in the probate division. The petition specifies the proposed guardian, identifies each parent (with addresses if known), states the reason guardianship is needed, and attaches a proposed order.

Notice has to go to the child's parents, to any adult siblings, to grandparents, and to specified relatives — California notice rules for guardianship are broader than family-law cases, and defective notice is one of the most common reasons a petition gets continued or denied on procedural grounds.

The Probate Court investigator's report

California requires an investigation of the proposed guardianship before an appointment is made. The investigation is conducted by the Probate Court investigator's office (in San Diego, the Family Court Services / Probate Investigator's office). The investigator interviews the proposed guardian, the child (if old enough), the parents (when possible), and other relevant adults, visits the proposed guardian's home, reviews the reasons for the guardianship, and files a written report with recommendations to the court.

The report matters. It is not a formality. A well-prepared proposed guardian has documents ready for the investigator (letters of consent from parents when applicable, school records, health-insurance information, proof of adequate housing), and can explain the arrangement clearly.

Temporary guardianship

When immediate legal authority is needed — the child needs to enroll in school Monday, or there is an urgent medical decision — the court can appoint a temporary guardian pending the full hearing. A Petition for Appointment of Temporary Guardian (GC-110) can be filed with the main petition or shortly after. Temporary guardianships last a specific period (usually up to six months) and expire unless renewed or replaced by the permanent order.

Objections and contested cases

A parent (or another interested party) can object to a proposed guardianship. When the parents object, guardianship is not granted lightly. Under Family Code section 3041 (which California courts apply to probate guardianship cases as the parental-preference standard), granting custody to a non-parent over a parent's objection requires a finding that awarding custody to the parent would be detrimental to the child, and that awarding custody to the non-parent is in the child's best interest. The parental-preference standard is a real protection for parents.

Termination of guardianship

A guardianship of a minor ends automatically at age eighteen, but before that, a parent can petition to terminate on a change of circumstances. The court applies a similar standard: continuing the guardianship must be in the child's best interest, or the change back to parental custody must not be detrimental. Termination cases are their own contested proceeding.

Guardianship of the estate mechanics

A guardian of the estate is a court-supervised fiduciary. The estate is inventoried and appraised, annual accountings are filed with the court, expenditures typically require court approval, and the assets are held for the minor's benefit until eighteen (or age twenty-five for certain structured settlements). Because guardianship of the estate is administratively intensive, families sometimes choose alternatives (a UTMA account, a special-needs trust, a settlement into a court-approved blocked account) depending on the size and source of the funds.

Ready to talk it through

Guardianship is one of the more procedurally specific areas of California family and probate practice, and defective filings can add months to the case.
