When a child travels with just one parent, airlines and border officials often want proof that the other parent approves. That proof is a letter of consent to travel with one parent, sometimes called a single-parent travel consent letter. Here is what to include, sample wording you can copy, and whether it needs to be notarized.
When you need a one-parent consent letter
You should carry one any time a child travels internationally, or even domestically, with only one parent, while the other parent stays home. Border and customs officials use it to confirm the absent parent has given permission, which helps prevent concerns about child abduction and keeps your trip moving smoothly.
What to include
- The child’s full legal name, date of birth, and passport or ID details
- The name of the parent who is traveling with the child
- The name and signature of the parent giving consent (the one not traveling)
- The travel dates and destination
- Contact information for the consenting parent
- A notary acknowledgment section
Sample letter of consent to travel with one parent
I, [consenting parent full name], am the parent/legal guardian of [child full name], born [date of birth], passport number [number]. I give my full consent for my child to travel with [traveling parent full name] to [destination] from [departure date] to [return date]. I can be reached at [phone/email]. Signed, [signature], [date].

Does it need to be notarized?
It is usually not required by law, but it is strongly recommended, and it is often expected at international borders. Notarizing the letter proves the consenting parent actually signed it, which is exactly what officials look for. You can notarize it online in minutes, from any state.

Why border officials ask for it
The concern behind the question is international parental child abduction. Officials at ports of entry are trained to notice a child crossing a border with one adult, and the consent letter is the fastest way to answer the question they are already thinking about.
Canada is the destination most people encounter this with, because Canadian border services explicitly recommend a consent letter for a child traveling with one parent and it is common for officers to ask. Plenty of other countries do the same, and airlines sometimes ask at check in before you ever reach a border.
The letter is rarely a legal requirement. It is close to a practical one, and the cost of not having it is being turned around at the airport.
Details that make a letter work
Two letters can contain the same facts and only one of them holds up. The difference is specificity.
Name the destination country and city rather than writing a trip abroad. Give exact departure and return dates rather than a month. Include the child’s passport number, and the consenting parent’s passport or identification details as well, so an officer can confirm the signer is a real identifiable person.
Give the consenting parent’s phone number and email, and give a number that will actually be answered while you are traveling, including the time difference. Add the address where the child will be staying.
Where the trip involves multiple countries, list them all. A letter that authorizes travel to one country and a child who turns up in a second is worse than no letter.
Situations that need more than the standard letter
The template covers the ordinary case. Some cases are not ordinary.
A custody order exists. Read it before you book. Many orders restrict international travel, require the other parent’s written consent, or require notice by a set deadline. Traveling in breach of a custody order is a serious matter, and no consent letter fixes it.
The other parent has died. Carry a certified copy of the death certificate rather than an explanation.
Sole legal custody. Carry a certified copy of the court order, not a photocopy of the first page.
The other parent cannot be located. This one has no paperwork answer and needs legal advice before you plan a trip.
Different surnames. Where the child’s surname differs from the traveling parent’s, carry the birth certificate as well, since that is the document that connects them.
Grandparents, relatives and school trips
The same logic applies when a child travels with anybody who is not a parent. In that case both parents typically sign, and the letter names the accompanying adult and their relationship to the child.
Many families also add a short medical authorisation letting the accompanying adult consent to emergency treatment. Ask the destination and the airline what they expect rather than guessing.
Notarizing it, including at short notice
The consenting parent signs in front of the notary rather than beforehand, and needs valid unexpired photo identification. Both parents do not have to be in the same place, and the consenting parent does not have to be in New York.
We notarize travel consent letters online in a few minutes, which is what makes this workable when somebody realizes the night before a flight. Carry the notarized original and keep a photograph of it on your phone.
If the destination country wants the document authenticated rather than merely notarized, that is an apostille, and it takes longer, so ask early.
Common mistakes worth avoiding
Writing it as a permission slip. Vague language such as I allow my child to travel with their father does not tell an officer where, when, or for how long. Specificity is the whole point.
Signing before the appointment. A notary has to witness the signature. A letter already signed has to be signed again.
Using an expired identification. Expired is expired, however recently it lapsed, and this is the most common reason a signing cannot be completed.
Carrying only a photocopy. Carry the notarized original in your hand luggage, not in a checked bag, and keep a photograph of it on your phone as a backup.
Leaving it to the last day. Notarization takes minutes. An apostille does not, and neither does replacing an expired passport you did not check.
A five minute checklist before you leave
Child’s passport valid, and valid far enough beyond your return date to satisfy the destination country. Consent letter notarized, with the original in your carry on. Birth certificate packed where surnames differ. Custody order or death certificate packed where either applies. The consenting parent’s phone reachable during your travel window. A copy of everything photographed on your phone and emailed to yourself.
Run that list a week out rather than the night before, because everything on it is fixable with a week and most of it is not fixable at the gate.
Frequently asked questions
Do both parents need to sign if they share custody?
When custody is shared, it is safest to have the non-traveling parent sign the consent. If only one parent has legal custody, documentation of that can help.
Can I notarize the letter online?
Yes. A commissioned notary can verify your signature over secure video, so you can complete it from anywhere in the U.S.
