A permission-to-travel letter is a letter or form in which a child's parent or guardian grants permission for the child to travel with a particular person who does not have legal custody. Such a letter may also provide permission for a minor child to travel alone.
There is no specific required format or form for a permission-to-travel letter, but LawDepot, Rocket Lawyer and the U.S. Passport Service Guide offer sample printable forms. The letter or form may include the child's name, date, passport number and place of birth. It identifies the person or persons permitted to travel with the child, expected travel locations, and the dates involved. The child's guardian or custodial parent must sign the form. U.S. Customs and Border Protection strongly recommends notarizing the letter.
