A child travel consent form is a signed letter from a parent or guardian authorizing a minor to travel without both parents present.

Most countries, including Canada and Mexico, require or strongly recommend a notarized copy when a child crosses an international border with only one parent or a non-parent adult.

What Is a Child Travel Consent Form?

A child travel consent form, also called a travel consent letter or minor travel authorization, is a written document signed by one or both parents or legal guardians that authorizes a minor under 18 to travel. The form records who authorized the trip, the destination, who accompanies the child, and how to reach the absent parent in an emergency.

Border officials use consent forms to help prevent international parental child abduction, which affects thousands of American children each year. A well-drafted form allows officers to confirm that both parents agree to the travel.

The form is different from an unaccompanied minor form, which is an airline-specific document for children traveling with no adult. Most U.S. airlines require unaccompanied minor services for children who are 12 or younger on domestic routes and for younger teens on international flights.

When Is a Child Travel Consent Form Required?

• International travel with one parent: Most countries that are parties to the Hague Apostille Convention recommend or require a signed, notarized consent letter from the non-traveling parent. Without it, border officers in many countries may refuse entry.
• International travel with a non-parent adult: Both parents or legal guardians should sign. Some countries also require proof of the adult's legal authority, such as a custody order.
• Domestic U.S. travel: No federal law requires a consent form for domestic flights, road trips, or train travel. A letter is still useful when a child travels across state lines without the custodial parent.
• School and camp trips: Schools and camps typically use their own permission slips specific to the trip. A general travel consent letter is usually separate and not substituted by school forms.

Check your state's requirements before finalizing any legal document, and verify the destination country's entry rules on the U.S. Department of State website.

International Travel: Country-by-Country Requirements

The table below summarizes child travel consent requirements for common destinations. Requirements change, so verify with the destination embassy or consulate before travel.

Always confirm current requirements with the destination country embassy or consulate, as rules change and enforcement varies by border crossing and individual officer.

What to Include on a Child Travel Consent Form

• Child's identifying information: Full legal name, date of birth, passport number, passport expiration date, and nationality.
• Traveling parent or adult information: Full legal name, address, phone number, passport or ID number, and relationship to the child.
• Absent parent or guardian information: Full legal name, address, daytime phone number, and passport or ID number. If the absent parent is deceased, attach a copy of the death certificate.
• Destination and travel dates: Specific countries, cities, or regions. List each leg of a multi-country trip. Include both departure and return dates.
• Purpose of travel: A brief description such as "family vacation," "school trip," or "medical visit."
• Authorization statement: Clear language authorizing the child to travel with the named adult and cross international borders for the described trip.
• Emergency contact: Name and phone number for a contact reachable during travel, in addition to the absent parent.
• Signature and date: Signature of the consenting parent or guardian. Both parents sign where possible.
• Notarization block: When notarization is required, include a notary acknowledgment with signature, seal, and commission expiration date.

Do not use vague date ranges such as "any time in 2026." Border officers in Mexico and Canada expect specific travel dates. An overly broad form may raise questions about whether consent was truly given for the specific trip.

Notarization: When You Need It and How to Get It

Notarization confirms that the signing parent appeared before a notary public, showed valid identification, and signed the form voluntarily. Countries that require or strongly recommend notarization include Mexico, Canada, the Dominican Republic, Costa Rica, and Panama.

For travel to these destinations, a form without a notary seal will typically not be accepted at the border.

Where to get a form notarized:

• Bank or credit union: Most branches offer free or low-cost notary services to account holders. Call ahead to confirm availability.
• UPS Store: Walk-in notary services are available at most UPS Store locations for a small fee, typically $5 to $15 per signature.
• AAA: AAA offices provide notary services to members at no charge in many locations.
• Online notary service: Services such as Notarize and NotaryCam allow remote notarization via video call. Confirm whether your destination country accepts remote online notarization before relying on it.
• Court clerk offices: Many county court clerk offices provide notary services to the public.

An apostille is a higher-level authentication that certifies a notary credential for use in Hague Convention countries. Most border officers do not require an apostille for a travel consent letter, but some embassies may request one when issuing a visa for a minor. Confirm with the destination country if you are unsure.

Special Situations: Custody, Deceased Parents, and Absent Parents

Standard consent letters assume both parents are living and available. Many families face more complex circumstances:

Child traveling with one parent in a shared custody arrangement:

In most states, both parents retain equal rights to travel with the child during their custody period. Some custody orders include travel restrictions or require advance notice. Review your custody order before booking international travel. The non-traveling parent should sign the consent form, and bring a certified copy of the custody order as supporting documentation.

One parent has sole legal custody:

If you have sole legal custody, bring a certified copy of the court order along with the child's passport. In many cases the sole-custody order satisfies border officers without a separate consent letter. Carrying both is the safest approach.

One parent is deceased:

Bring the original or a certified copy of the death certificate. Attach it to the consent form and note on the form that consent of the other parent is not possible due to death.

The other parent refuses to sign:

If a parent with legal rights refuses to consent to travel, you generally cannot take the child abroad without a court order. Courts can grant permission for specific international travel when one parent unreasonably withholds consent. Consult a family law attorney if this applies to your situation.

Child traveling with a grandparent or other non-parent adult:

Both parents should sign the consent form. Include a letter of authorization naming the accompanying adult, their relationship to the child, and authorization to make emergency decisions on the child's behalf. Many parents also include a limited medical authorization alongside the travel consent.

The other parent cannot be located:

Document your efforts to contact the other parent in writing. If your custody order gives you authority to make travel decisions, carry a certified copy. If you do not have such authority, consult an attorney about seeking a court order before traveling internationally.

Domestic Travel: Flights, Road Trips, and Cruises

The Transportation Security Administration does not require a child travel consent form for domestic flights. TSA checks ID for travelers 18 and older; children under 18 are not required to present ID at a security checkpoint.

For domestic road trips across state lines, no state or federal law requires a child travel consent form. However, if a custody order restricts the geographic range of travel, you may need written permission from the other parent or a court modification.

Cruises departing from U.S. ports that stop at international destinations, including Mexico and the Caribbean, are considered international travel at those ports of call. If the cruise stops in Mexico, Canada, or the Dominican Republic, a notarized consent form is recommended even if the ship departs from a domestic port.

Amtrak and domestic bus carriers do not require consent forms for minors traveling with one parent or another adult.

How to Fill Out and Use the Form

Follow these steps to complete a child travel consent form correctly:

• Use the child's full legal name as it appears on their passport. Nicknames may cause a mismatch with travel documents.
• Include passport numbers for both the child and the absent parent. Border officers can use these to verify identity.
• List specific travel dates and destinations, not open-ended date ranges. A form covering 'any date in 2026' will likely be questioned.
• Have the form signed and notarized by the absent parent before travel. Plan at least one week in advance to allow time for notarization.
• Make several photocopies and keep the original on your person, not in checked luggage. Some border officials will take a copy for their records.
• If traveling to a country that requires documentation in Spanish or French, have the form professionally translated and attach the translation to the original.
• Carry supporting documents alongside the consent form: the child's birth certificate listing both parents, a custody order if applicable, and a death certificate if one parent is deceased.
• Provide a direct phone number for the absent parent. Border officers may contact them by phone to verbally confirm consent before allowing entry.

Common Mistakes to Avoid

• Using vague travel dates: Open-ended consent forms raise concerns at the border. Use specific first and last dates of travel.
• Omitting passport numbers: A consent form without the passport number is harder for officers to verify. Include numbers for the child and the absent parent.
• Skipping notarization: Even if the destination only recommends notarization, having it done eliminates one potential reason for delay.
• Bringing a photocopy instead of the original: Many border officials require the original document with the notary seal. Photocopies or digital files are typically not accepted.
• Not updating the form after a custody change: A form based on an old custody arrangement may conflict with your current court order. Update whenever custody changes.
• Forgetting supporting documents: A consent form alone is often not enough. Carry a birth certificate, passport, and custody order or court documents.
• Using informal language: Handwritten notes or casual letters carry little weight with border officials. Use a formal, typed consent form with a notary seal.
