Power of Attorney vs Guardianship for a Child in California
They Are Not the Same Thing
A parent who wants to give a relative temporary authority over their child has two options that sound similar but work very differently. A power of attorney is a private document signed by the parent. A guardianship is a court order issued by a judge. The legal weight, duration, and protections are not comparable.
Power of Attorney for a Minor
Under California Family Code Section 6910, a parent can sign a document delegating authority to another adult to consent to medical treatment for the child. This delegation:
- Is signed privately — no court involvement
- Is revocable by the parent at any time
- Expires on the date stated in the document (or when the parent revokes it)
- Covers only what the parent specifically delegates
The practical reality: many schools, hospitals, and agencies do not accept a private power of attorney as sufficient authority. School districts sometimes require formal custody documentation for enrollment. Hospitals may question the document's validity for non-emergency treatment. Insurance companies may refuse to process claims.
A power of attorney also cannot override a parent's decisions. If the parent shows up and contradicts the instructions in the power of attorney, the parent's wishes control.
Caregiver's Authorization Affidavit — The Better Non-Court Option
California actually has a stronger non-court tool than a power of attorney: the Caregiver's Authorization Affidavit (CAA) under Family Code Section 6550. For relatives, the CAA provides:
- School enrollment authority under Education Code Section 48204, which schools must accept by law
- Full medical and dental consent for relatives within the fifth degree of kinship (Items 5–8)
- No court filing, notarization, or judge's signature required
- Signed under penalty of perjury, with statutory legal protections for third parties who rely on it
The CAA is specifically designed for the situations where caregivers most often need authority — school and doctors — and it carries statutory weight that a private power of attorney does not. Schools and healthcare providers are legally required to accept a properly executed CAA.

Guardianship
A guardianship under Probate Code Section 1500 requires filing a petition in the Superior Court, paying the $435 filing fee (or applying for a waiver), giving notice to all required parties, submitting to a court investigation, and attending a hearing. If granted, the judge issues Letters of Guardianship (GC-250) — court-issued proof of the guardian's authority.
Guardianship gives the caregiver the legal rights and responsibilities of a parent: residence, education, medical consent, and authority over daily decisions. Parental rights are suspended (not terminated), and the guardianship remains in effect until the child turns 18, the court orders termination, or another event ends it.
Side-by-Side Comparison
| Feature | Power of Attorney | CAA | Guardianship |
|---|---|---|---|
| Created by | Parent's signature | Caregiver's signature | Court order |
| Court involvement | None | None | Full proceeding |
| Duration | As stated, or revoked | While child lives with caregiver | Until child turns 18 or court ends it |
| School enrollment | Often rejected | Legally mandated acceptance | Full authority |
| Medical consent | Limited to what parent delegates | Full (for qualifying relatives) | Full |
| Can parent override? | Yes, at any time | Yes, at any time | Only through court petition |
| Third-party acceptance | Inconsistent | Legally required | Court-issued proof of authority |
When You Need Which
Power of attorney works for very short-term, specific situations — a parent going on a two-week trip who wants to authorize emergency medical treatment. It is fragile and limited.
CAA is the right tool when you are caring for a relative's child and need school and medical authority, but the parent is still involved and the arrangement is temporary or informal. It is free, fast, and legally enforceable.
Guardianship can be appropriate when a parent is unavailable (incarcerated, in treatment, deceased, or unreachable), when the arrangement needs to be long-term, or when you need authority that a parent cannot unilaterally revoke. It is not required for every benefits application: eligible relatives can apply for CalWORKs child-only grants and Medi-Cal for a child without formal probate guardianship.
