A child crossing a border with one parent, a grandparent, or alone raises an immediate question for officials trained to spot abduction and trafficking: does the absent parent know? A travel consent letter answers it on the spot. U.S. Customs and Border Protection recommends one for any minor traveling without both parents, and many countries, Mexico and Canada among them, expect it.
This form covers all three situations: traveling with another adult, with one parent, or alone as an unaccompanied minor, with trip dates, itinerary, and optional emergency medical consent. Download it in Word and PDF and sign before a notary.
When a travel consent letter is expected
- International trips with one parent: the most common case; border officers routinely ask the traveling parent for a letter from the other parent.
- Trips with grandparents, relatives, or friends' families: the accompanying adult has no legal relationship to prove, so the letter does the proving.
- Unaccompanied minors: airlines require their own unaccompanied minor paperwork, and a notarized parental consent letter complements it, especially internationally.
- School and group travel: chaperoned trips across borders where each child carries an individual consent.
For purely domestic trips no law demands a letter, but airlines can ask about a minor's accompaniment, and a letter resolves any question at the gate in seconds.
What border officials look for in the letter
Officers want to match three things: the child in front of them, the adult presenting the letter, and a consenting parent they can call. The letter should therefore state the child's full name, date and place of birth, and passport number if there is one; the accompanying adult's name and relationship; the destination and dates; and a phone number where the signing parent will actually answer. Notarization is not legally mandatory for U.S. exit, but CBP recommends it and foreign officials give a notarized letter far more weight.
Some countries have their own forms
A few destinations require a specific format: Mexico's SAM form applies to minors residing in Mexico who travel alone, and South Africa has notably strict documentary rules for minors. Check the destination country's consulate page before relying on any generic letter, including this one.
Consent letters when parents are separated
The letter matters most, and is scrutinized hardest, when parents are divorced or separated. The non-traveling parent's notarized consent is the standard expectation, and if a custody order restricts travel, the order controls: a letter cannot override it. A parent with sole custody should carry the custody order instead of, or alongside, a consent letter; a widowed parent should carry the death certificate. When consent from the other parent cannot be obtained, some families need a court order authorizing the trip, which is beyond what any form can do.
Frequently asked questions
Is a child travel consent form legally required?
No U.S. federal law requires it, but U.S. Customs and Border Protection recommends it for any minor traveling without both parents, and many foreign countries expect one at entry or exit. In practice, not carrying one risks delays, secondary inspection, or a refused boarding.
Does the travel consent letter need to be notarized?
Strongly recommended, especially for international travel: CBP suggests notarization and foreign border officials rely on it. For a domestic flight with a relative, a signed letter without a notary is usually enough.
Do I need a letter if I travel abroad alone with my own child?
Yes, this is the classic case. Officers see one parent and ask about the other. Carry a consent letter signed by the non-traveling parent, or the document explaining their absence: a sole custody order or a death certificate.
How long is a travel consent form valid?
This template is trip-specific: it covers the named destination and dates and expires at the end of the return date. Trip-specific letters are exactly what officials prefer over open-ended ones.
Should the letter include medical consent too?
For a child traveling with an adult, yes: the option in this form lets the accompanying adult authorize emergency care abroad if you are unreachable. For broader or longer coverage at home, use a dedicated child medical consent form.
