Do I need a child travel consent letter and how do I get one notarized?

When you need a consent letter

A consent letter is a border control document, not a booking one. trip1 does not need one to book a family hotel room, and hotels do not ask for it. The people who ask are airline staff at the departure gate and immigration officers on arrival.

• A child travels with one parent while the other stays at home. The parent who is not travelling signs.
• A child travels with a grandparent, another relative, a family friend or a group leader. Both parents sign.
• A child travels alone or as an unaccompanied minor. Both parents sign.
• The parents are separated or divorced, or the child has a different surname from the adult travelling.

If one parent has sole legal custody, or the other parent has died, carry the court order or the death certificate instead of a letter. That is the document an officer will want to see.

What the letter should contain

• The child's full name, date of birth and passport number.
• The full name, passport number and contact details of the adult travelling with them.
• The destination, the travel dates and where the child will be staying.
• A clear sentence of consent, such as a statement that the child is travelling outside the country with that named adult with your permission.
• The full name, signature, passport number and contact phone number of each consenting parent.
• The date the letter was signed.

Write it in English where possible and add a translation if the destination's officials work in another language. Keep it to one page so it can be read at a glance.

How to get it notarized

A notarized letter is one you sign in front of a notary public, who checks your identity and adds a stamp and signature. That stamp is what turns a printed page into something an official will trust.

Book an appointment, bring photo ID, and do not sign the letter in advance. The notary has to witness the signature itself, so an already-signed page has to be redone.

Banks, law offices, print and shipping shops and some public libraries offer notary services, and remote online notarization is now accepted in many places. Fees are usually small. In the United Kingdom the equivalent is a notary public or, for some purposes, a solicitor.

A few countries also want an apostille, an extra certification confirming the notary is genuine. Check the destination's embassy site if you are told an apostille is needed, because it adds days to the process.

Countries that check this strictly

South Africa is the strictest well-known example. Children under 18 travelling in or out generally need an unabridged birth certificate naming both parents, plus a parental consent affidavit when one or both parents are not travelling. Airline staff check this before boarding.

Canada publishes a recommended consent letter template and its border officers may ask for it. United States authorities advise a notarized letter for children crossing into Canada or Mexico.

Many other countries have no formal published rule but their officers can still ask, particularly when a child's surname does not match the adult's. Carrying the letter costs nothing and removes the question.
