A child is flying to visit family with a grandparent, or going abroad with one parent while the other stays home. Nobody thinks about paperwork until an officer at the border asks a question the family cannot answer.
No Pennsylvania law requires a consent letter. That is precisely why so many families are caught out by how often one is asked for.
Why officials ask
The reason is unglamorous and serious: international child abduction and trafficking. A child crossing a border with an adult who is not their parent is exactly the pattern authorities are trained to look at twice.

A consent letter resolves the question in seconds. Without one, the alternatives are phone calls to a parent in a different time zone, a delayed flight, or being turned back — none of which is a good way to start a holiday.
It is a practical requirement, not a legal one. Nobody will fine you for travelling without a consent letter. They may simply decline to let the child travel, which in the moment amounts to the same thing.
When you need one
| Situation | Consent letter? | Who signs |
|---|---|---|
| Child travels abroad with both parents | Not needed | — |
| Child travels abroad with one parent | Recommended | The non-travelling parent |
| Child travels with a grandparent or relative | Strongly recommended | Both parents |
| Child travels with a family friend or group | Strongly recommended | Both parents |
| One parent has sole legal custody | Recommended, with the court order | The custodial parent |
| One parent is deceased | Recommended, with the death certificate | The surviving parent |
| Domestic flight within the US | Rarely required | Check the airline |

What the letter should say
Vague permission is weak. A letter that names specifics is far more persuasive to someone deciding whether to let a child through.
- The child’s full legal name and date of birth, exactly as they appear on the passport
- The full names of the accompanying adults and their relationship to the child
- The destination, including cities and countries
- The travel dates, departure and return
- The reason for travel — holiday, visiting family, a school trip
- The non-travelling parent’s contact details, including a number reachable while the child is away
- An explicit statement consenting to the travel, and to medical treatment if needed
- The signature and printed name of the consenting parent or guardian

Keep it to one page. An officer is scanning for names, dates and a signature, not reading an essay.
Why notarization matters here
Nothing in the letter is self-proving. Anyone could type a paragraph and sign a parent’s name to it, and an official at a border has no way to know otherwise.
A notarized letter changes that. The notary has verified the signer’s identity from government photo identification and witnessed the signature, which converts an assertion into something with a verified person behind it.

Where both parents share custody and the child is travelling with someone else, both should sign. They do not have to attend together — each can be notarized separately, as with any Pennsylvania notarization.
Custody complicates it
If custody is shared, the non-travelling parent’s consent is the point of the exercise, and a letter without it is of limited use.

Where one parent has sole legal custody, bring a certified copy of the custody order. A consent letter supported by the order is the combination that works. Where a parent has died, carry a copy of the death certificate.
A notary cannot advise you on custody. Whether your order permits international travel, and whether you need the other parent’s consent, are legal questions — and answering them is outside what a notary may do, as covered in what a notary can and cannot do. If custody is contested, speak to a lawyer before booking.
School trips and organised groups
Organised trips usually supply their own consent and medical forms, and those often need notarizing too. Read them well before the deadline rather than the night before — some ask for both parents, and coordinating that at short notice is harder than it sounds.
Group forms rarely replace a travel consent letter for international trips. They authorise the organisation to supervise and to seek treatment; they do not necessarily satisfy a border officer asking why this child is leaving the country with these adults. Carrying both is the safer arrangement.
| Document | What it authorises | Who usually asks for it |
|---|---|---|
| Travel consent letter | The child travelling without a parent | Border officers, airlines |
| Group medical release | Treatment while in the group’s care | The organiser |
| Custody order copy | That the signing parent may decide | Border officers, if custody is raised |
| Birth certificate | The relationship between adult and child | Border officers, if surnames differ |
Practical points that save trouble
- Match the passport exactly. Nicknames and shortened forms create the confusion the letter exists to prevent.
- Carry the original. Keep it with the passports, in hand luggage.
- Take a photograph of it and email a copy to the travelling adult.
- Date it close to travel. A letter written two years ago invites questions.
- Check the destination’s rules. Some countries are markedly stricter than others.
- Bring the child’s birth certificate if surnames differ across the party.

Getting it notarized
Bring the completed letter unsigned, along with current government photo identification. The notarial act is an acknowledgment or a signature witnessing depending on how the letter is drafted, and the fee is capped — $5 for the first individual, as set out in what a Pennsylvania notary may charge.
We notarize travel consent letters throughout the year at our Bethlehem notary office, with a noticeable rush before school holidays. Walk in, or call ahead if both parents need to attend. General guidance on documents for children travelling internationally is published at USA.gov.
Frequently asked questions
Is a notarized travel consent letter required by law?
No Pennsylvania statute requires one, and it is not a legal document in the way a passport is. It is strongly recommended for international travel and is routinely requested by border officers and airlines, so travelling without it is a practical risk rather than a legal offence.
Who needs to sign the letter?
Any parent or legal guardian not travelling with the child. Where both parents share custody and only one is travelling, the non-travelling parent signs. Where a child travels with grandparents or another adult, both parents normally sign.
Does it have to be notarized?
Not strictly, but notarization is what makes it credible to an official who has no way of verifying a signature. An unnotarized letter is a piece of paper anyone could have typed; a notarized one has a verified signer behind it.
What should the letter include?
The child’s full name and date of birth, the names of the accompanying adults, the destination, the travel dates, the reason for travel, and contact details for the non-travelling parent, plus their signature.
What if one parent has sole custody?
Bring a certified copy of the custody order or the relevant court document. A consent letter from the custodial parent, supported by that order, is usually the right combination.
Do I need one for domestic travel?
Rarely for flights within the United States, though individual airlines set their own rules for unaccompanied minors. It is international travel, and land crossings in particular, where the letter genuinely matters.
Travelling before the holidays?
Bring the letter unsigned and photo ID — it takes about five minutes. Both parents can be notarized separately if needed. Hablamos Español.
