How to Get Guardianship of a Grandchild in California
Starting Point: You Are Already Doing the Parenting
Most grandparents looking into guardianship are not starting from zero — they have already been caring for the grandchild for weeks, months, or years. A parent went to prison, entered treatment, left and stopped coming back, or passed away. The grandchild is already in your home. What you need now is the legal authority to match the reality.
In California, probate guardianship of the person under Probate Code Section 1500 is the standard pathway for grandparents. It gives you legal and physical custody of the child, the right to make educational and medical decisions, and a court order that schools, doctors, and benefits offices will accept without question.
Who Can Petition
Any relative of the child, including a grandparent, can petition for guardianship under Probate Code Section 1510. You do not need the parents' permission to file — though parental consent simplifies the process significantly. If the child is 12 or older, the child can also nominate you as their preferred guardian, and the court must appoint you unless it finds the appointment contrary to the child's best interest.
The Basic Filing Steps
Assemble the Judicial Council forms: GC-210(P) (the petition), GC-210(CA) (child information attachment), GC-212 (confidential screening form), FL-105/GC-120 (UCCJEA declaration), and GC-248 (Duties of Guardian). All are free from courts.ca.gov.
Check for local county forms. Your county's Superior Court may require supplemental local forms — a cover sheet, investigator questionnaire, or local order template.
File at the courthouse. The filing fee for a guardianship of the person is $225 in most counties; a few counties charge $35 to $50 more. If the child receives Medi-Cal, CalFresh, or SSI — or if the child's household income is below poverty guidelines — you can file for a fee waiver using form FW-001-GC. The waiver is based on the child's finances, not yours.
Serve notice on all required people. Parents, the child if 12 or older, any legal custodian, a court-appointed guardian of the child's estate, and any other person nominated as guardian must receive personal service at least 15 days before the hearing. Mail notice to grandparents, siblings 12 or older, the parent, guardian, or custodian of a sibling under 12, other relatives named in the petition, and anyone caring for the child if different from the legal custodian. Mail lead time is 15 days in the county, 20 days in another county, 25 days out of state, and 35 days outside the United States. A proposed guardian who is not related must also notify the California Department of Social Services. If a parent cannot be found, document your search efforts; the court can dispense with notice or order another method.
Cooperate with the court investigator. The court assigns an investigator who will visit your home, interview you and the child, check the proposed guardian's and household adults' backgrounds, and file a report with a recommendation. Check your county court's instructions to see whether it requires Live Scan fingerprinting.
Attend the hearing. The probate judge reviews the investigator's report and hears from any objecting parties. If a parent objects, the judge must find that staying with the parent would be detrimental to the child and that guardianship is in the child's best interest.

If a Parent Agrees
When both parents consent — or when one parent consents and the other is absent — the process is substantially simpler. A consenting parent signs form GC-211, which waives their right to formal service and indicates agreement. The hearing becomes largely procedural, though the judge still independently reviews the investigator's report.
If a Parent Objects
A contested guardianship is harder but not impossible. The court applies a "best interest of the child" standard, and parental preference carries constitutional weight. If a parent objects, the judge must find that staying with the parent would be detrimental to the child and that guardianship is in the child's best interest.
If the parents' situation involves ongoing substance abuse, incarceration, or abandonment, the factual record often supports the guardianship even over an objection.
What Guardianship Gives You
Once the judge signs the order (GC-240) and the clerk issues Letters of Guardianship (GC-250), you have legal authority to:
- Enroll the child in school and access educational records
- Consent to medical, dental, and mental health treatment
- Apply for public benefits on the child's behalf (CalWORKs, Medi-Cal, CalFresh)
- Make day-to-day decisions about the child's care and residence
Parental rights are suspended, not terminated. Parents retain the right to petition the court for visitation or to terminate the guardianship if their circumstances change.
Financial Help After Guardianship
Grandparents with a probate guardianship order can apply for a CalWORKs child-only grant, which provides monthly cash assistance for the child regardless of the grandparent's own income. The child also qualifies independently for Medi-Cal and CalFresh.
Kin-GAP (Kinship Guardianship Assistance Payments) offers higher monthly payments but requires a prior juvenile dependency case — it is not available through the standard probate guardianship path alone.
