A notarized letter for travel with a child is a signed, witnessed statement in which a parent or guardian authorizes a minor to travel without them, verified by a notary public who confirms the signer’s identity. The letter itself is short. Getting the details right — who signs, what it says, and what extra authentication your destination requires — is what keeps your child moving through airports and border checkpoints instead of sitting in a secondary inspection room.
What to Put in the Letter
No government publishes a universal template, so the goal is to include enough detail that any border agent or airline employee can quickly see who authorized the trip, who the child is with, and where they are going. A complete letter covers:
- The child’s full legal name, date of birth, and passport number.
- The consenting parent’s or guardian’s full legal name, home address, phone number, and email. If both parents share custody and only one is traveling with the child, the non-traveling parent provides the consent.
- The accompanying adult’s full legal name, relationship to the child, home address, phone number, and passport number for international trips.
- Travel details: departure and return dates, destinations, flight numbers if known, and where the child will be staying.
- An emergency contact who is not on the trip, with name, phone number, and relationship to the child.
- A clear consent statement, such as: “I acknowledge that my child is traveling outside the country with [name of adult] with my permission.”1USAGov. International Travel Documents for Children
- Signature and date lines for each consenting parent or guardian, plus a separate space for the notary’s seal and signature.
If both parents share legal custody and neither is going on the trip, both should sign.2U.S. Department of State. Travel with Minors If more than one child is traveling, you can list all of them in a single letter as long as each child’s information is clearly identified.
Medical Authorization
When your child is traveling with someone other than a parent, add a medical authorization clause. It gives the accompanying adult temporary authority to consent to emergency medical treatment if you can’t be reached. A workable version: “I authorize [name of accompanying adult] to consent to any necessary emergency medical treatment for [child’s name] during the dates of travel.” Without this language, a hospital or clinic in a foreign country may delay treatment while trying to locate you.
Signing in Front of a Notary
A notary public verifies that the person signing the letter is who they say they are. They do not evaluate whether the letter is legally sufficient or whether you actually have parental rights; they confirm identity and witness the signature. That limited role is still what makes the document hard to forge or dispute.
Notaries work at most banks, credit unions, shipping stores, law offices, and some public libraries. Bring a valid government-issued photo ID such as a driver’s license or passport, and do not sign the letter beforehand. The notary has to watch you sign. After witnessing your signature and confirming your ID, they apply their official seal and signature.
Fees are set by state law and most states cap them between $2 and $25 per notarial act. Many banks notarize for account holders at no charge. If both parents need to sign and they live in different places, each can visit a separate notary.
Remote Online Notarization
If getting to a notary in person is difficult, remote online notarization (RON) is now authorized in most states. The process runs over a video call: you upload your government-issued ID, answer identity verification questions, sign the document on screen while the notary watches, and the notary applies a digital seal. RON is particularly useful when one parent lives in a different city or state from the other. Before relying on it for international travel, check whether your destination accepts digitally notarized documents. Most do; a few still require a traditional ink seal.
Who Actually Needs to Sign
A two-parent household where both parents agree is the simple case. Many situations are not that simple, and the letter has to match your actual legal arrangement.
Sole Legal Custody
If you have sole legal custody, you are the only person who needs to sign. Carry a certified copy of the court order granting that custody alongside the letter so border agents can confirm your authority without the other parent’s signature.1USAGov. International Travel Documents for Children
Deceased Parent
When one parent has died, the surviving parent should carry a copy of the death certificate with the consent letter. That explains why only one signature appears and prevents extra questioning at the border.1USAGov. International Travel Documents for Children
A Parent Who Won’t Consent
If the other parent refuses to sign, you generally cannot take the child out of the country without court approval. The usual route is to file a motion in family court asking for permission to travel internationally with the child. The court hears both parents and decides based on the child’s best interests. Courts often approve international trips when reasonable safeguards are in place to ensure the child’s return, but the process takes time. Start well before your travel date. Do not attempt to leave the country without either the other parent’s written consent or a court order expressly authorizing the trip.
Existing Custody Orders
If a custody agreement or court order includes travel restrictions, such as a prohibition on leaving the country or a requirement to give the other parent advance notice, those restrictions override anything in your consent letter. Carry copies of all relevant orders when you travel.
How Long the Letter Stays Good
No federal law in the United States sets an expiration date on a child travel consent letter, and notarization doesn’t create one either. That doesn’t mean an open-ended letter is a good idea. Officials view undated or old letters with suspicion because they can’t tell whether the consenting parent still approves of the current trip or whether family circumstances have changed.
Write a new letter for each trip. Match the validity dates to your actual departure and return, with a few buffer days on each end for delays or itinerary changes. If your child travels frequently with the same adult, draft a fresh letter each time rather than reusing one from months ago. Notarization is cheap, and a trip-specific letter draws far fewer questions.
Extra Steps for International Travel
A notarized letter is enough for many destinations, but some countries require an apostille — a certificate attached to your document by a government authority that verifies the notary’s seal and signature are genuine. It exists because of the Hague Apostille Convention, which currently has 129 member countries.3HCCH. Convention of 5 October 1961 – Status Table A document with an apostille is accepted across all member countries without separate embassy legalization.
In the United States, where you request the apostille depends on who notarized the document. If a state-commissioned notary did the work, you request it from that state’s Secretary of State office. If a military notary or federal official was involved, the apostille comes from the U.S. Department of State’s Office of Authentication Services.4U.S. Department of State. Preparing a Document for an Apostille Certificate Processing times vary, so build this into your timeline.
Some countries also require the letter to be translated into the local language. Use a professional translator and have the translation notarized as a separate step. Do not notarize the original and then translate the notarized version; the translation needs its own authentication.
Countries With Their Own Rules
A few destinations impose requirements well beyond a standard notarized consent letter. Check directly with the embassy or consulate before you travel,5U.S. Customs and Border Protection. Children Traveling to Another Country Without Their Parents but two examples show how different the rules can be:
- Brazil requires Brazilian minors traveling abroad to carry a specific government-issued travel authorization form, even if the child holds dual citizenship and is traveling on a foreign passport. If the child travels with one parent, the other parent must sign the authorization. If a third party is accompanying the child, that person generally must be a Brazilian national unless the court has granted separate approval. The authorization must be apostilled if signed outside Brazil.6Governo Federal. Travel Authorisation for Brazilian Minor Children
- South Africa requires children entering the country to carry an unabridged birth certificate showing both parents’ names. If the child is traveling with only one parent, officials may require a parental consent affidavit from the absent parent along with a copy of that parent’s ID or passport.7South African Government. What Are the Requirements for Travelling with Children
Countries update these rules without much notice. Verify current entry requirements with the destination’s embassy or consulate at least a month before travel.
What Happens if You Skip It
Arriving at a border without proper documentation can mean extended questioning while officials try to verify parental consent by phone, or at the other end of the spectrum, denied boarding by the airline, refused entry at a foreign port, or detention while authorities investigate whether the child is being removed without authorization.2U.S. Department of State. Travel with Minors None of this gets resolved on the spot. Writing the letter takes about thirty minutes and getting it notarized takes a short trip. Do it for every trip, even if the last few went fine without one.
