A child travel consent form is a signed, notarized letter in which a parent or legal guardian authorizes their minor child to travel internationally without them. U.S. Customs and Border Protection does not legally require the letter, but strongly recommends that any child crossing an international border without both parents carry one.1U.S. Embassy In Poland. Child Travelers Without it, the traveling adult and the child can face extended questioning, delayed boarding, or denial of entry. The letter takes about fifteen minutes to draft and a short trip to a notary to finalize.
When You Need One
CBP recommends a notarized consent letter whenever a child travels internationally with only one parent, a grandparent, another relative, a legal guardian, or any non-parent adult, and also when a minor flies or cruises alone.1U.S. Embassy In Poland. Child Travelers Chaperones on school trips, sports teams, or educational tours should carry a separate letter for each child in the group.
Destination countries set their own rules on top of the U.S. guidance. The State Department advises contacting the embassy or consulate of your destination country before departure to confirm exactly what documentation the border authorities expect.2U.S. Department of State – Bureau of Consular Affairs. Travel with Minors Cruise lines add another layer: major operators typically require a notarized consent form for any minor boarding without both legal guardians, and a missing or invalid form can mean being turned away at the gangway.
Domestic travel within the United States generally does not call for a consent form, and TSA does not require identification for children under 18 on domestic flights.3Transportation Security Administration. Do Minors Need Identification to Fly Within the U.S.? Airlines run their own unaccompanied minor programs with separate paperwork, so check the carrier’s policy before booking.
What to Include
The letter does not need to follow a rigid template. What matters is that it covers every piece of information a border agent would want to verify. CBP’s guidance calls for the following:1U.S. Embassy In Poland. Child Travelers
- The child’s full legal name (matching the passport exactly), date of birth, and passport number.
- Each consenting parent or guardian’s full name, address, phone number, and email.
- The traveling adult’s full name, relationship to the child, and contact information. If the child is traveling alone, state that clearly.
- The purpose of the trip, the destination country and city, departure and return dates, and flight or cruise details if available.
- At least one emergency contact who can be reached if the consenting parent is unavailable.
Set a specific start and end date. An open-ended letter with no expiration can raise suspicion at the border and offers less protection to the non-traveling parent. If the trip is extended, draft and notarize a fresh letter for the new dates rather than trying to amend the original.
USAGov recommends the letter be written in English and include language along the lines of: “I acknowledge that my child is traveling outside the country with [name of adult] with my permission.”4USAGov. International Travel Documents for Children Some destination countries also require the letter to be translated into the local language, and in certain cases require that the translation itself be notarized by a certified translator.
Getting It Notarized
No federal regulation requires the letter to be notarized, but CBP strongly advises it because notarization proves that the person who signed was properly identified as the actual parent or legal guardian.1U.S. Embassy In Poland. Child Travelers Without a notary seal, the letter carries far less weight with border agents and airline staff.
Bring the unsigned letter and a valid government-issued photo ID to a notary public. Sign the document in the notary’s presence, never beforehand. The notary verifies your identity, witnesses the signature, and applies an official seal. Notaries are available at banks, UPS stores, law offices, and courthouses, and mobile notaries will come to you.
Fees vary by state. Most states cap what a notary can charge per signature, and those caps generally fall between $2 and $25. Remote online notarization by video call is legal in most states and works for trips to countries that do not require an apostille. If your destination does require an apostille, use a traditional in-person notary, because remotely notarized documents are not accepted for apostille processing in every state.
Adding Medical Authorization
A travel consent letter covers the border crossing, but it does not automatically let the traveling adult authorize medical treatment if the child is hurt or falls ill. A separate medical authorization, or a medical section added to the same document, closes that gap. It typically grants the designated adult authority to consent to emergency treatment, including ambulance transport, X-rays, medication, and hospital care, when the parent cannot be reached in time.
Include the child’s health insurance information, known allergies, current medications, and the name and phone number of the primary care doctor. For a child with a chronic condition like asthma or diabetes, note the treatment protocol. This section matters most on longer trips, in remote destinations, and on group travel where a chaperone may need to act quickly for several children.
When You Also Need an Apostille
Some destination countries require an extra authentication step called an apostille, a government-issued certificate confirming that the notary who witnessed the signature is legitimately commissioned. The apostille is recognized by more than 120 countries that are parties to the 1961 Hague Apostille Convention.5HCCH. HCCH Apostille Section Without it, some border authorities may treat your notarized letter as unverified.
To get one, submit the original notarized consent form to the Secretary of State’s office in the state where the notary is commissioned. You cannot get an apostille from a different state than the one that commissioned the notary. Fees typically fall between $2 and $26, and processing times range from same-day to several weeks depending on the state. If the destination country also requires a translation, complete and notarize the translation before submitting everything for the apostille.
Sole Custody, Deceased Parent, and Refusal to Sign
Not every family has two parents available to sign.
Sole Legal Custody
If you have sole legal custody, you do not need the other parent’s signature. Carry a certified copy of the custody order issued by the court along with the consent letter.4USAGov. International Travel Documents for Children Border agents may ask to see the decree at busy international checkpoints. The copy must be court-certified; a photocopy of the order is not the same thing.
Deceased Parent
When the other parent is deceased, bring a certified copy of the death certificate along with the consent form. Some countries, including Canada, specifically expect the traveling parent to present a death certificate when the other parent is not traveling.6Government of Canada. Minor Children Travelling to Canada Even where it is not strictly required, having the death certificate on hand prevents prolonged questioning.
The Other Parent Refuses to Sign
If the other parent will not sign, you generally cannot proceed with international travel on your own; doing so can be treated as interference with the other parent’s custody rights. The usual option is to file a motion in family court asking a judge to authorize the trip. The judge weighs whether the trip serves the child’s best interests and whether there is a risk of non-return. Keep all communication about the refusal in writing, since it may support your motion. Some parents resolve the conflict by offering make-up parenting time for the days missed during travel.
Carrying and Presenting the Form
Carry the original notarized hard copy in your carry-on bag, not in checked luggage, and not only on your phone. A digital scan is a useful backup, but airline agents and border officers expect to see an original notary seal and signature on paper. Bring photocopies too, in case an officer wants to keep one.
Expect to be asked for the letter at multiple points: airline check-in, the departure gate, customs and immigration at the destination, and again when re-entering the United States. CBP officers review the letter to confirm the scope of travel permission and verify that the document is authentic.7U.S. Customs and Border Protection. Children Traveling to Another Country Without Their Parents Anything that looks off, such as mismatched names, an expired date range, or a missing notary seal, can trigger a secondary inspection lasting an hour or more. Before leaving home, check that names match the passport, that the dates cover the full trip including any possible extension, and that the notary seal is clearly legible.
The Risk of Traveling Without Consent
Taking a child out of the United States without the other parent’s knowledge or consent is not only a custody violation; it can be a federal crime. Under the International Parental Kidnapping Crime Act, anyone who removes or attempts to remove a child under 16 from the country to obstruct the other parent’s custody or visitation rights faces up to three years in federal prison, a fine, or both.8Office of the Law Revision Counsel. 18 U.S. Code 1204 – International Parental Kidnapping The FBI investigates these cases and can seek an Unlawful Flight to Avoid Prosecution warrant against the offending parent.9Federal Bureau of Investigation. Raising Awareness: International Parental Kidnapping
The statute recognizes narrow defenses: the parent acted under a valid custody order, was fleeing domestic violence, or failed to return the child due to circumstances beyond their control and made reasonable efforts to notify the other parent within 24 hours.8Office of the Law Revision Counsel. 18 U.S. Code 1204 – International Parental Kidnapping Once a child is taken abroad, U.S. courts and law enforcement have limited ability to compel a return, and foreign governments may treat the situation as a civil parental dispute rather than a crime. A properly executed consent form removes any ambiguity about whether the trip was authorized.
