International travel with a child who has a different last name is generally allowed. The name difference alone doesn't prevent a parent or guardian from traveling with a child. You may, however, be asked to show how you're related.
For example, a parent who kept their birth name after marriage may have a different surname from the one on the child's passport. Bring a document that connects the two names rather than relying on an explanation at the airport.
What should you bring to the airport?
- The child's passport. Check that the name on the ticket matches the passport.
- A birth certificate or adoption record showing your relationship to the child.
- A marriage certificate or legal name-change document, if it helps explain the different surnames.
- Custody or guardianship papers when they affect your authority to travel.
- A minor travel consent letter, if another parent or guardian isn't traveling and the destination requires or recommends one.
Check the country's requirements
The U.S. Department of State recommends carrying proof of your relationship to a child abroad. A destination country may also specify which records must be originals, notarized, or translated.
For example, the UK government says border officers may ask for a birth or adoption certificate, or a marriage certificate if the names differ. Check with the destination's embassy or consulate before departure.
If a grandparent is accompanying the child, read our guide to grandparents traveling with grandchildren.
