Apostille and Document Legalisation in Portugal
Ensure your foreign documents are legally recognised in Portugal through the correct apostille or consular legalisation procedure, managed by our legal team.
Our Apostille and Legalisation service ensures your foreign public documents are legally valid in Portugal. We handle the certification process so your documents are accepted by Portuguese authorities for official matters like visa applications or property purchases.
For a foreign public document to be considered valid in Portugal, its authenticity must be certified. Under the 1961 Hague Convention, of which Portugal is a signatory, this is done via an 'apostille.' The apostille is a certificate issued by a designated authority in the document's country of origin. For countries not party to the Hague Convention, a more complex process of consular legalisation is required, involving multiple authentications.
The Challenge of International Document Validation
Clients often underestimate the complexity of this requirement. They may be unsure whether an apostille or consular legalisation is needed, which authorities to contact in their home country, or what the exact procedural steps are. This leads to delays, rejected documents by Portuguese authorities like AIMA, and stalled legal and administrative processes.
When this is the right step
You are applying for a Portuguese residence visa and need to submit foreign documents like a criminal record or birth certificate. You are purchasing property and your lawyer requires authenticated identity or financial documents from your home country. You are getting married, divorced, or registering a birth in Portugal using documents issued by another country. You are enrolling in a Portuguese university and must submit your foreign academic diplomas. You are incorporating a company and need to present foreign corporate documents or a power of attorney.
Our Structured Legalisation Service
Our firm manages the entire legalisation process, leveraging a clear understanding of both the Hague Apostille Convention and country-specific consular legalisation protocols. We provide precise instructions for your specific case and liaise with the competent authorities, including the Portuguese Prosecutor General's Office (Procuradoria-Geral da República), which is responsible for issuing apostilles for Portuguese documents to be used abroad.
What's Included in Our Service
Our Process
The process begins with a review of your documents and requirements. We then provide a clear action plan. Our team handles all submissions and follow-ups, providing you with regular updates until the fully legalised documents are securely delivered to you.
What happens if this is skipped
Without the correct apostille or legalisation, your documents will be rejected outright by Portuguese authorities like AIMA or the Civil Registry. This immediately halts your application, forcing you to restart the entire process. You will lose valuable time, forfeit non-refundable application fees, and face months of delays that jeopardise your residency, property purchase, or other legal objectives.

Frequently asked questions
What is an apostille?
An apostille is a certificate that authenticates the origin of a public document, like a birth certificate, making it valid in other countries that are part of the Hague Convention.
This may vary depending on your situation.
When do I need an apostille in Portugal?
You need an apostille for any foreign public document you intend to use for official purposes in Portugal, such as for residency, citizenship, or marriage applications.
This may vary depending on your situation.
What if my document's country is not in the Hague Convention?
If the country is not a member, the document must undergo a more complex process called consular legalisation at the Portuguese consulate in that country.
This may vary depending on your situation.
How long does it take to get a document apostilled?
The time varies by country, but it typically takes several business days. Our service manages this process for you to ensure it's done correctly and efficiently.
This may vary depending on your situation.
Can you apostille a document for me in my home country?
An apostille must be issued by the designated authority in the country where the document originated. We guide you on how to obtain it or work with partners to facilitate it.
This may vary depending on your situation.
Is an apostille the same as a translation?
No, an apostille certifies the document's authenticity, not its content. You will likely still need a certified translation of the document into Portuguese.
This may vary depending on your situation.
Which documents typically require an apostille?
Common documents include birth certificates, marriage certificates, criminal record checks, and university diplomas that you need for official use in Portugal.
This may vary depending on your situation.

Online Apostille Service (since 2025)
On 15 March 2025 in Lisbon and 15 April 2025 nationwide, the Portuguese Ministério Público launched an online apostille service through the portal `apostila.ministeriopublico.pt`. For electronic documents, the request can be submitted, processed and delivered fully online. For physical documents, the portal is used for scheduling and payment; the document itself is presented in person at a designated PGR service.
The online service integrates the e-Parceiro programme, allowing eligible Portuguese entities that regularly issue apostille-eligible documents — including certain law firms — to register as authenticated issuers, streamlining the verification step for their own client documents.
THE-Ö Legal coordinates apostille submissions through the online portal for eligible electronic documents and through the district PGR services for physical documents, in each case delivering the fully apostilled originals to you.
Hague vs Non-Hague Destinations
The apostille under the 1961 Hague Convention is valid only for destination countries that are parties to the convention (125+ countries as of 2026). For a Portuguese document to be used in a country that is not a Hague signatory, the apostille is replaced by consular legalisation: endorsement by the Portuguese consular network (Direção-Geral dos Assuntos Consulares e das Comunidades Portuguesas), followed in some cases by an additional endorsement from the destination country's consulate in Portugal.
Since Portugal joined the Hague Convention in respect of most Portuguese public documents in 2019, the historical routine of consular legalisation for Hague destinations no longer applies — apostille is the correct route. For the residual set of non-Hague destinations — certain African, Middle Eastern and Central Asian countries — consular legalisation remains the route. We identify the correct end-to-end path during intake.
Origin-country apostille authorities
- **United States** — apostille is issued by the Secretary of State of the issuing US state. State-issued vital records typically need county-level certification before the state apostille is added.
- **United Kingdom** — apostille is issued by the Legalisation Office of the Foreign, Commonwealth & Development Office (FCDO). Court and academic documents often require an intermediate notarial certification before FCDO handling.
- **Brazil** — since Brazil's accession in 2016, apostille is added by Brazilian cartórios extrajudiciais under the delegation of the Corregedoria Nacional de Justiça.
- **Russia** — apostille is issued by the Ministry of Justice or its delegated regional authorities. Since 2022, verification of Russian apostilles has become more nuanced for some Portuguese destination-authority contexts.
- **Ukraine** — apostille is issued by the Ministry of Justice, the Ministry of Foreign Affairs or the Ministry of Education depending on the document type.
- **Spain** — apostille is issued by the Spanish Ministry of Justice or the delegated Colegio Notarial for notarial documents.
