Arizona Grandparent Travel Consent for a Minor Child

Traveling with a grandchild or relative's child when you're not the legal parent raises a practical question: what documentation do you need? The answer depends on where you're going and how you're getting there.

In-State Travel

For driving around Arizona — school, appointments, family trips within the state — a valid A.R.S. § 14-5104 Power of Attorney documents the parent's delegation of care authority. It does not guarantee acceptance by every institution, so check ahead with a hotel, hospital, or other provider when you expect to need the document.

You don't need a separate travel consent letter for in-state trips if you already have the POA. Carry a copy in your glovebox or phone.

Domestic Air Travel

TSA does not require children under 18 to show ID for domestic flights. An adult traveling with a minor needs their own valid ID. TSA does not require proof of relationship or custody documents for domestic travel.

That said, airline staff occasionally ask about the relationship between an adult and a child, especially for young children traveling with someone who doesn't share their last name. Carrying a copy of the POA and the child's birth certificate avoids any delay at the gate.

If the child is flying as an unaccompanied minor (airlines define this differently, usually children ages 5–14 flying alone), you'll need to fill out the airline's unaccompanied minor form. A valid POA gives you the authority to complete that form and designate who picks the child up at the destination.

Out-of-State Travel

There is no federal law requiring a travel consent letter for domestic trips between states. But carrying documentation is smart practice. The POA shows anyone who asks — hotel staff, hospital ERs, police — that you have authorization.

The more important consideration for out-of-state travel is medical consent authority. A.R.S. § 14-5104 is an Arizona instrument; another state's provider applies its own rules and may not accept it. Contact the provider before the trip and do not rely on the Arizona POA alone for non-emergency care.

For planned out-of-state trips, especially to states with their own caregiver consent laws (like California's Caregiver Authorization Affidavit), carrying both the POA and a simple notarized travel consent letter from the parent provides extra coverage.

International Travel

This is where the POA stops being sufficient. International travel with a minor who is not your child requires additional documentation:

Passport: For a child under 16, both parents or guardians generally must appear or provide consent for a U.S. passport. If a parent cannot appear, the State Department lists alternatives such as a court order, a death certificate, a declaration of incompetence, or Form DS-5525 when a parent cannot be located. A POA under A.R.S. § 14-5104 alone does not establish the required custody or consent. Follow the State Department's current instructions for the child's situation.

If the child already has a valid passport, you can travel internationally with it.

Consent letter for border crossings: The United States does not require evidence of both parents' permission for a minor to travel internationally, but some destination countries require written, sometimes notarized, permission when a child travels with someone who is not a parent or legal guardian. Check the destination's current rules before travel. A letter may help answer questions, but it does not guarantee entry.

The consent letter should include the child's full name and date of birth, both parents' names and contact information, your name and relationship to the child, travel dates and destinations, and both parents' notarized signatures.

Mexico and Canada: Canada's official guidance says a child traveling to Canada with an adult other than a parent or legal guardian should have written permission from the parents or guardians; the letter does not need to be certified, but an officer may refuse entry if not convinced the trip is authorized. Mexico's departure authorization (the SAM form or a notarized or court-issued equivalent) applies to Mexican minors and foreign minors with resident status who leave Mexico alone or with a third party; foreign minors visiting as tourists are exempt. Check the current Mexican consulate and carrier instructions for the child's itinerary, including whether a foreign-language document needs translation or legalization.

When You Can't Get a Parent's Signature

If a parent cannot provide travel consent, the Arizona POA alone may not satisfy passport or destination-country requirements. Check the State Department's current passport rules and the destination's entry and exit requirements; consult an Arizona lawyer about guardianship only if you need a court appointment and the statutory grounds are met.
