A trip of a few hours to Puerto Iguazú or Ciudad del Este is, legally, a departure from Brazil. The rules for Brazilian children and teenagers apply in these cases too.
Common situations
- With both parents: the child’s own travel document.
- With only one parent: the child’s own document and travel authorization from the other parent or guardian.
- With grandparents, aunts and uncles, friends or a school: the child’s own document and authorization from the parents.
- Alone: the child’s own document and authorization; also check the transport company’s requirements.
Use the official CNJ (Brazil’s National Council of Justice) form and guidance (links in the sources) and check the formal requirements, such as the signature, on the form itself.
In the destination country
Argentina and Paraguay have their own immigration rules and may ask for proof of the relationship between the child and the accompanying adults. Confirm with the destination’s immigration authority before you travel.
