According to Federal Law 8.069 / 1990, children under 18 years of age are not permitted to stay in hotels without being accompanied by a parent or legal guardian. If the minor is accompanied by an adult who is not a parent, written authorization must be submitted when checking in at the hotel. The authorization must be notarized and signed by both parents. In the case of a minor accompanied by only one of the parents, it is necessary to present a notarized authorization signed by the absent parent, along with a notarized copy of that parent´s ID. Please note that all minors under 18 years of age must also present valid and official photo ID. In the case of foreign minors, the requirements listed above still apply and must be followed in accordance with the law.
