California Guardianship Requirements: Age, Eligibility, and What the Court Checks

The Basics of Who Can Serve

California does not set a maximum age for guardians, and it does not restrict petitions to relatives. Under Probate Code Section 1510, a petition may be filed by a relative, the child if they are 12 or older, or another interested person or social agency. The person appointed guardian must be an adult, but there is no upper age limit. A 70-year-old grandparent files the same petition as a 30-year-old aunt.

The court's standard is straightforward: appointment must serve the child's best interest. The investigator evaluates whether you can provide a stable home, whether you have the physical and emotional capacity to care for the child, and whether the child's living situation with you is safe.

Eligibility Requirements

To be appointed guardian, you need to:

• Be at least 18 years old
• Be legally competent (not under a conservatorship for capacity-related reasons)
• Pass a Live Scan fingerprint background check through the California Department of Justice and FBI
• Clear the Child Abuse Central Index screening
• Complete the Confidential Guardian Screening Form (GC-212), which covers your residential history, employment, and personal background

Having a criminal record does not automatically disqualify you. The court and investigator review the nature, severity, and recency of any offenses. A decades-old misdemeanor is treated very differently from a recent conviction involving violence or children. The court has discretion.

Guardianship for Teenagers

If the child is 12 or older, California gives them specific statutory rights that shape the proceeding:

• Nomination: A minor aged 12 or older can formally nominate a preferred guardian under Probate Code Section 1502. The court must appoint that person unless it finds the appointment contrary to the child's best interest.
• Independent petition: A teenager aged 12 or older has standing to file a guardianship petition on their own behalf.
• Notice: The teenager must receive personal service of the petition and hearing notice at least 15 days before the court date — the same requirement that applies to parents.

These rights mean that in a guardianship involving a teenager, the court pays close attention to the child's expressed preferences. If the teenager actively wants to live with you and nominates you as guardian, that carries significant weight.

What the Court Investigator Evaluates

After you file, the court assigns an investigator under Probate Code Section 1513. The investigator:

1. Visits your home to assess safety and living conditions
2. Interviews you, other household members, and the child
3. Reviews the child's school and medical records
4. Interviews the parents if they are available
5. Runs background checks on all adults in the household
6. Prepares a written report with a recommendation

The investigation fee ranges from $400 to over $800 depending on the county. If you qualify for a fee waiver (Form FW-001-GC), the investigator fee is covered.

What Does Not Disqualify You

Some things caregivers worry about that are not automatic barriers:

• Modest income: The court does not require wealth. Financial stability matters, but probate guardians can apply for CalWORKs non-needy caretaker grants, CalFresh, and Medi-Cal for the child.
• Renting: You do not need to own your home.
• Being single: There is no requirement for a two-parent household.
• Not being a relative: Anyone with a genuine connection to the child can petition, though relatives generally face less scrutiny.
• Health conditions: The court considers whether you can provide day-to-day care, not whether you are in perfect health.

The Legal Standard

For an uncontested case where parents consent or cannot be found, the standard is the child's best interest. For a contested case where a parent objects, the bar is higher: under Family Code Section 3041, the court requires clear and convincing evidence that placing the child with the objecting parent would cause detriment, and that awarding custody to the nonparent is required to serve the child's best interests.

Putting It Together

Meeting the technical requirements — age, background check, screening form — is the easy part. The harder question is whether you are ready for the obligations that come after the order: annual status reports (Form GC-251), court oversight, and the practical reality of raising someone else's child.
