Does a Child Travel Consent Form Need to Be Notarized?
United States · Canada · United Kingdomversion 2026-09
What US, Canadian and UK sources say about notarizing a child travel consent form, and which cruise lines ask for a notarized original.
Notarisation is the part of this paperwork that people ask about most, because a stamp has to be arranged in advance and a notary may not be open on the day before a flight. What the government sources actually say differs from country to country, and the cruise lines add rules of their own. The form on this site prints a notary block on request, so the same page can be signed and stamped or signed only.
The stamp question, source by source
- United States. CBP states that no regulation requires the authorization letter to be notarized, and that it highly advises it. Its stated reason is identification: notarisation is proof that the notary identified the people signing as the child's actual parents or legal guardians. CBP adds that certain destination countries require a consent letter for children arriving or leaving without both parents, in some cases notarized — so where a stamp is compulsory, the requirement comes from the country being entered.
- Canada. Global Affairs Canada states that any adult may witness the signing and that a notary public is strongly recommended. Whatever arrangement is used, original signed letters are best on that guidance.
- United Kingdom. GOV.UK addresses permission rather than stamps: a letter from the person with parental responsibility is usually enough to show permission, and the guidance states no notarisation requirement for that letter.
What a notary does here
CBP describes the value of notarisation as proof that the notary has identified the person signing the letter as the actual parent or legal guardian. On that description, the notary identifies the signer and watches the signature being made. Nothing in the description covers the wording of the letter, which is written by the family.
Jurisdiction table
| Jurisdiction | Notarisation required? | What the source says | Source | Checked |
|---|---|---|---|---|
| United States (outbound) | No regulation requires it | CBP highly advises notarisation; some destination countries require a consent letter, in some cases notarized | S1, S2 | 13 Sep 2026 |
| Canada | Not legally required | Any adult may witness; notary public strongly recommended; original signed letters are best | S7 | 13 Sep 2026 |
| United Kingdom | No notary requirement stated | Permission of everyone with parental responsibility, or a court; a letter is usually enough | S11 | 13 Sep 2026 |
| Royal Caribbean | Original notarized letter | Adults who are not the parent or legal guardian must present an original notarized letter signed by at least one parent | S15 | 13 Sep 2026 |
| Carnival | Original signed letter | Original signed letter from the absent parent strongly recommended (notarisation not required by the published policy) | S17 | 13 Sep 2026 |
| Norwegian | Own form, Canada letter preferably notarized | Parent/Guardian Consent Form signed by both living parents or guardians; for Canada itineraries a letter preferably notarized | S19 | 13 Sep 2026 |
If no notary is available
The fallback options differ as much as the rules. Canada's guidance allows any adult to witness the signing, subject to the witness having reached the age of majority in the province or territory. U.S. guidance states that no regulation requires the stamp, while advising it, so a letter signed and dated without a stamp is still a letter. The United Kingdom does not state a notary requirement for permission letters. Where a country's entry rules or a company's own policy ask for a notarised original, the timeline for arranging one belongs in the trip planning rather than in the week of departure.
Cruise lines that ask for a notarized original
Among the four lines whose published pages were checked, Royal Caribbean is the one that asks for an original notarized letter when an adult who is not the parent or legal guardian travels with the child. Norwegian asks for its own consent form signed by both living parents or guardians, and adds a letter that is preferably notarized on Canada itineraries. Carnival's published policy strongly recommends an original signed letter. Disney Cruise Line asks for its own authorization form. The cruise line comparison sets out each policy side by side, and the plain answer page covers whether a letter is expected at all.
Frequently asked questions
Is a notarized letter required by law in the United States?
CBP states that no regulation requires it, and that it highly advises it; its stated reason is that the notary identifies the people signing. Destination countries are the other possible source of a stamp requirement, which CBP advises checking.
Who can witness a consent letter in Canada?
Any adult may witness the signing, according to Global Affairs Canada, which strongly recommends a notary public. Its FAQ adds that the witness must have reached the age of majority — 18 or 19, depending on the province or territory.
Do cruise lines accept a letter without a notary stamp?
The four lines checked do not share one rule. Royal Caribbean's page requires an original notarized letter from a parent where the accompanying adult is not the parent or legal guardian. Carnival's strongly recommends an original signed letter instead. Norwegian asks for its own consent form and, on Canada itineraries, a letter that is preferably notarized.
