Notarised Parental Consent for Cross-Border Minor Travel

What You Actually Need

For a minor to leave Portugal without both parents present, Portuguese law requires a written, dated authorisation signed by the parent(s) or holder(s) of parental responsibility. Border authorities and receiving countries may additionally require signature recognition and, for cross-border destinations, an apostille or consular legalisation.

This page focuses on the cross-border scenario — a Portuguese-issued consent to be shown to airline check-in staff, foreign border control or a foreign accompanying adult. Domestic travel within Portugal without both parents typically does not require notarial recognition; the government publishes a template that parents can complete themselves.

When Notarial Recognition Is Actually Required

Whether presencial signature recognition or a full authenticated document is required depends on the destination country and the accompanying adult. Some Schengen destinations accept a self-signed authorisation. Non-Schengen and non-Hague destinations frequently require signature recognition plus apostille or consular legalisation. Airlines apply their own additional documentation checks.

For destinations that historically required consular legalisation — including certain African, Middle Eastern and Latin American countries — the process routinely involves a lawyer-recognised signature plus apostille (for Hague signatories) or Portuguese consular legalisation followed by destination-country consular endorsement.

Domestic PT-Only Travel vs Cross-Border

For a minor travelling only within Portugal without both parents present, no notarised authorisation is legally required. The Portuguese government publishes a template that parents can complete and sign themselves; this is a DIY step, not a legal service.

For a minor leaving Portugal — the cross-border scenario — the legal requirements change. Presencial signature recognition on the authorisation is commonly required by receiving countries. Apostille or consular legalisation is required when the authorisation is to be presented to a non-Portuguese authority. This is where THE-Ö Legal is engaged.

Common Scenarios

• Child travelling alone as an unaccompanied minor — airline paperwork plus notarised parental consent.
• Child travelling with one parent (the other parent is abroad or unavailable) — notarised consent from the non-travelling parent.
• Child travelling with a grandparent or another family member — notarised consent from both parents (or the sole holder of parental responsibility).
• Child travelling with a summer-camp or school group — notarised consent from both parents, often required in a specific template.
• Child returning to a parent living abroad after visiting the other in Portugal — notarised consent + apostille (for Hague destinations) or consular legalisation (for non-Hague).

Apostille and Consular Legalisation

For a destination country that is a party to the 1961 Hague Convention, a Portuguese apostille under Decreto-Lei n.º 76-A/2006 is added by the Procuradoria-Geral da República after our signature recognition. Fee €10.20, typically immediate. For non-Hague destinations, we coordinate consular legalisation through the Portuguese consular network of the Ministry of Foreign Affairs.

In some cases the destination country also requires the endorsement of its own consulate in Portugal. We identify the correct end-to-end route during intake and confirm the timeline before starting.

How We Deliver

Intake by video or phone: we confirm the destination country, the accompanying adult, the date of travel and the specific requirements imposed by the airline and the receiving authority. We draft the authorisation in the correct language pair (English + Portuguese by default; Russian or Spanish on request), recognise the signature(s) presencial or by videoconference under the November 2021 regime, and coordinate any subsequent apostille or consular step.

Delivery of the signed and legalised originals is by secure courier or in person, timed to your travel date.
