Arizona Guardianship vs Power of Attorney for a Minor: Which Do You Need?

A grandparent or relative in Arizona who suddenly has a child in their home faces a confusing choice: do you need a power of attorney or a guardianship? They sound similar, but they work completely differently — different costs, different authority, different timelines, and different consequences if things go wrong.

Here is what separates them.

Power of Attorney (A.R.S. § 14-5104)

This is the fast, no-court option. A parent signs Form GNPPOA10F in front of a notary and one witness, delegating day-to-day parenting authority to a relative for up to six months. No filing fee. No judge. No hearing.

What it gives you:

• Authority to enroll the child in school
• Medical, dental, and mental health consent
• Permission to sign field-trip slips, sports waivers, and school forms
• Daily care decisions (transportation, childcare pickups, activities)

What it doesn't give you:

• Legal custody (the parent keeps that)
• The ability to consent to adoption or marriage
• Any authority once the parent revokes it in writing
• Passport applications (federal law requires both parents or a court order)
• Protection if a parent takes the child back

The parent can revoke the POA in writing at any time before it expires. If the parent dies or becomes incapacitated, do not assume the delegation remains usable for ongoing decisions; get Arizona legal advice about the document and the available next steps.

Guardianship (Title 14, Chapter 5)

This is the court route. You file a petition in Superior Court asking a judge to grant you legal guardianship of the minor. The parents must be formally notified, and they have the right to object and attend a hearing.

What it gives you:

• Full legal decision-making authority
• Physical custody of the child
• Authority that survives a parent's change of heart (only the court can undo it)
• Standing to apply for a passport, enroll in benefits, and make all major decisions
• Permanence — no six-month expiration

What it costs:

• Typical filing fee of $200–$300, depending on the county
• Fingerprinting and background check if required; Arizona law requires it for a proposed guardian who is not related to the child
• Service of process on both parents
• At least one court hearing, sometimes more if a parent contests
• Weeks to months of waiting for a hearing date
• Optional attorney; fees vary with the case, especially if a parent contests it

Arizona also offers a temporary guardianship under A.R.S. § 14-5207. If necessary, the court may appoint a temporary guardian for an initial period of up to six months and may extend the appointment if a longer period is in the child's best interests. The petition still requires a hearing and notice, and the court must find that § 14-5204's appointment conditions are met.

Side-by-Side Comparison

When to Use Each

Use the POA when:

• The parent is cooperative and available to sign
• The situation is genuinely temporary (rehab, deployment, medical recovery)
• You need authority today, not in six weeks
• The child's school and doctor will accept it (most do)

Use guardianship when:

• The court may appoint a guardian if each living parent consents, the parental rights of the living parents have been terminated, or the minor is at least 16, is not in an open Title 8 dependency case, and no parent is willing or able to exercise guardian duties; appointment must also be in the child's best interests
• The arrangement has lasted more than a year and serial POA renewals are drawing institutional resistance
• You need authority the POA can't provide (passport, interstate travel, certain benefits)
• Another family member is disputing the child's placement
• The child is in a DCS dependency case and formal placement is required

Many families start with a POA and move to guardianship later if the parent doesn't return. That is a perfectly normal trajectory, and courts understand it.

Making the Decision

If the parent will sign, start with the POA — it covers school and medical needs immediately. If the POA keeps getting renewed past the first year, or if institutions start pushing back, that is the signal to talk to a legal aid organization about filing for guardianship.

The Arizona School and Medical Consent Guide covers both paths in detail — including how to fill out Form GNPPOA10F, what to do when a school or clinic refuses your paperwork, and how to decide when the court route becomes worth it.
