Parents or a legal guardian travelling with children under 18 years must present the child's birth certificate and an identity card with photo (for example, a passport) at check-in. For international travels to Brazil, if only one of the parents is travelling with the child, she/he must present – in addition to the child's certificate of birth and identity card with photo – a letter authorising the trip signed by the other parent with a notarial certification of signature. In the event that the parents or the legal guardian, as applicable, cannot or are unwilling to give this authorisation, a judicial authorisation is required. People who intend to travel to Brazil with children must consult with the Brazilian consulate before travelling for more information.
