Portugal Certificate Attestation in Dubai — the Legalisation Route, Not an Apostille

About Portugal Certificate Attestation

Portugal has issued apostilles since the Convention entered into force for it on 4 February 1969, and that is exactly why Portuguese documents so often reach Dubai in a form the UAE chain cannot use. A Portuguese counter will apostille a degree certificate without hesitation, because for most destinations that is the right answer — but the United Arab Emirates is not a Contracting Party to that Convention, and Portugal's own apostille service states that only states which have ratified or acceded to it receive documents bearing an apostille. What the UAE requires instead is published not by Portugal but by the UAE's own embassy in Lisbon, in three short steps. The harder part is everything around those steps: Portugal splits this work across two entirely different institutions depending on where a document is going, the ministry counter that handles it holds no notarial powers of its own, and a growing share of Portuguese certificates are now issued as an access code rather than as a piece of paper — which matters a great deal when a document has to be physically stamped more than once.

Why an apostille does not finish a UAE file

The clearest statement of the limit comes from Portugal's own apostille service. Asked directly which countries receive documents bearing an apostille, it answers: only those which have ratified the 1961 Hague Convention or acceded to it. The same service describes the instrument as certifying public acts issued in the territory of one Contracting State that are to be presented in the territory of another Contracting State of the same Convention — a limit built into the definition and running in both directions at once.

Portugal is a Contracting Party: it signed on 20 August 1965, ratified on 6 December 1968, and the Convention entered into force for it on 4 February 1969. The United Arab Emirates is not. The Convention's status table lists 130 Contracting Parties as at its last update of 30 June 2026, and the UAE is not among them — the list runs from Ukraine straight to the United Kingdom, with nothing in between.

One point deserves care rather than confidence, because the sources do not fully settle it. The Portuguese ministry's English-language guidance states that its public desk does not intervene in cases where a document has an apostille; the Portuguese-language version of the same carve-out is framed instead around documents destined for Hague Convention states. Those are not quite the same rule, and neither text addresses a UAE-bound document that already carries an apostille. We therefore do not tell you that an apostille already on your document is fatal, and we do not tell you it is harmless. If your document has one, that is a question to settle with the counter before anything else is added to it — and it is a good reason not to obtain one for a UAE file in the first place.

Portugal's apostille authority is a prosecutor's office — and the apostille is all it issues

This is where the corridor catches out people who have done their research, and it is worth being blunt: an earlier version of this page got it wrong in exactly the way described here, which is why it is now near the top.

In most countries the apostille comes from the foreign ministry. In Portugal it does not. The competent authority is the Procuradoria-Geral da República — the Attorney-General's Office — under article 2 of Decreto-Lei n.º 86/2009 of 3 April, with that competence also exercised by the Regional Public Prosecutors of Porto, Coimbra and Évora and by coordinating Public Prosecutor magistrates for Guimarães, the Azores and Madeira. It is a prosecution service rather than a diplomatic one, and it is the right address for a document travelling to Spain, Brazil or the United Kingdom.

The reason it is not the address for a UAE document is worth stating precisely, because the precise version is the defensible one. The point is not that this office is barred from doing other things — no Portuguese source says that, and we will not invent it. The point is about the instrument. That office administers the apostille; the apostille reaches only Contracting States; the UAE is not one. So the apostille route simply does not arrive at the destination, whoever administers it.

The Portuguese foreign ministry draws the same line from its own side. Legalisation of Portuguese public acts intended to produce effects in States party to the Hague Convention, it states, falls to the Attorney-General of the Republic as the authority competent for issuing apostilles — and its own public desk does not intervene in those cases. Read together with the sentence above, that gives you the map: Hague destination, prosecutor's office; and for everywhere else, a ministry counter.

The route the UAE Embassy in Lisbon publishes

For the chain itself the authoritative source is not a Portuguese one, and that is not a gap in our research — it is a real feature of this corridor. Portugal does not publish, in positive terms, what its ministry does for documents heading to countries outside the Convention. The UAE does. Since it is the UAE's acceptance of your document that is finally at stake, its embassy in Lisbon is the right authority to follow, and under the heading "How to attest a document?" it sets out what it expects for Portugal-issued documents in four short bullets:

• Legalize the document at the Portuguese Ministry of Foreign Affairs.
• Attest the legalized document at the Embassy of the UAE in Lisbon.
• Complete the process by attesting the document at MoFA in the UAE.
• Attestation will be done at the embassy's premises. No prior appointment required.

What that means in practice — and the one join nobody has published

Two things are worth noticing about that list. The first is what it does not contain. Across every content-bearing page of the UAE's mission in Portugal the words "apostille" and "Procuradoria-Geral da República" do not appear once; the mission describes the Portuguese step only as legalisation at the foreign ministry. The second is the embassy itself — the Embassy of the United Arab Emirates in the Portuguese Republic, in Lisbon, at Praça do Príncipe Real, established in 2010. The UAE publishes no other mission for Portugal: there is no mission page for Porto or for any other Portuguese city. If you find a listing elsewhere for a UAE consulate in Porto, it is a directory artefact rather than a mission, and the UAE's own site is the only authority worth trusting on the point.

The honest complication sits in the first bullet. On the Portuguese side, the counter you would go to is the public service desk of the Directorate-General for Consular Affairs and Portuguese Communities, in Lisbon and in Porto. What that desk publishes as its service is not "legalisation" — it is the issuance of declarations concerning Portuguese administrative documents that are authentic or authenticated. Neither government has published anything cross-referencing the two: the UAE asks for a legalisation at the Portuguese ministry, the Portuguese ministry publishes a declaration, and no source on either side states that the one satisfies the other.

We would rather tell you that plainly than paper over it, because it is exactly the kind of gap that turns into a wasted trip. It is also, frankly, where the work is. Confirming the precise product the embassy will accept before a document is submitted — rather than after — is the part of this corridor that benefits most from someone doing it every week.

The seal-or-signature test that decides most files

The ministry desk publishes one condition that settles more cases than any list could, and it is worth quoting rather than paraphrasing: it acts on Portuguese administrative documents that are already authentic or authenticated. It does not make them so. It states plainly that it has no notarial competence to recognise signatures.

Alongside that it gives a single worked example — stated for medical certificates, which is the only document class it exemplifies — and the example generalises better than any enumeration. If the certificate carries the issuing professional's stamped seal, the desk will issue its declaration on it directly. If the document carries only a signature, that signature must first be recognised before a notary, and the desk then issues its declaration over that recognition.

What makes this useful is the trigger. It is not the class of document — not "birth certificates go this way, degrees go that way" — but whether the paper in your hand carries a seal or only a signature. Applied to the documents people actually bring us, that reading suggests a workable rule rather than a list to memorise. A birth, marriage or death certidão from a conservatória, or a document issued and sealed by a court or a ministry, normally arrives already sealed and complete. An employer's experience or salary certificate, a company declaration or a power of attorney is a private document usually carrying a bare signature, and on the desk's published test would need that signature recognised first. We present that as our reading of a published rule rather than as a published list, because no Portuguese authority publishes a list of which document types need a notary.

One Portuguese peculiarity widens the options considerably if a prior step is needed. In Portugal, lawyers and solicitadores — not only notaries — may recognise signatures, authenticate private documents and certify copies and translations, and the law gives those acts the same probative force as if a notary had performed them.

The online-certificate problem: an access code is not a piece of paper

This is the issue we meet most often on Portuguese files, and catching it before anything is ordered saves the most time of anything on this page.

Portugal has moved much of its civil registry online, and an online certificate is not delivered as a document. It is delivered as an access code. The government states the legal position precisely: handing the access code to any public or private entity is legally equivalent to handing over a paper certificate — and printing the document has no value as a certificate.

Set that against a chain in which more than one office places a physical stamp on a physical original and the difficulty is obvious enough. We should be careful about how far we take it, though: no Portuguese or UAE authority has actually published how an access-code certificate is handled at these counters, or whether one can be legalised at all. What is published is the legal-value rule above, and what we know from doing the work is that a printout is a poor thing to present at a counter that is looking for a seal. So we confirm the acceptable form before a certificate is ordered rather than after.

Two related points are worth knowing. Birth, marriage and death certificates can be requested in the international model — a version intended for presentation to entities outside Portugal, carrying translation into several languages, requestable in person or by post and issued on paper only. Whether UAE authorities prefer it, accept it, or would rather have a national-model certificate with a translation, is not published by either side, so we treat it as an option to weigh rather than an answer. And note that the international model does not legalise itself for Dubai: the exemption attached to multilingual civil-status extracts applies only among the twenty-five states bound by that convention, all European apart from Cabo Verde. Portugal is one; the UAE is not.

Finally, a stale premise worth correcting because it still circulates: the "certidão permanente" model no longer exists for the civil registry — it ceased to be issued under article 8 of Portaria 181/2017 of 31 May. It does still exist for the commercial registry, which is a different register with different rules.

Degrees, diplomas and the recognition trap

Portuguese law does distinguish public from private institutions, and it does so explicitly — but the place it is written down matters. That split is published as part of the apostille service: documents from public teaching establishments are public acts in their own right, while documents from private higher-education institutions need prior authentication by the national higher-education authority. That is a rule of the Hague route, which by its own terms does not serve the UAE, and no Portuguese authority publishes an education-specific rule for the consular route at all. We mention it because the underlying logic is the same one the ministry desk applies — a document must be authentic or authenticated before the desk will act — not because it has been published as the rule for a UAE file.

If you are sent to the higher-education authority, note that it changed in 2026: the Directorate-General for Higher Education closed its institutional cycle in March of that year and its functions passed to the Instituto para o Ensino Superior, I.P. Several official pages, including some apostille services, still name the former body and its old address.

One distinction matters more than any of this, and it is the one most often blurred. That authority's declaration attests the recognition of a Portuguese institution and of its degree-conferring courses. It says nothing about your document, and it is neither an attestation nor a legalisation. It is also not published as a Portuguese legal requirement — the authority frames it as responding to what destination-country entities frequently ask for. Recognition and attestation are separate processes with separate authorities, and treating one as a substitute for the other is how files stall.

Company documents, and a rule imported from the wrong country

Commercial files run on the same seal-or-signature test as personal ones. A certificate issued and sealed by a registry is one thing; a letter signed by a director is a private document and would need its signature recognised — by a notary, a lawyer or a solicitador — before the ministry desk acts on it.

The Portuguese commercial registry has its own version of the online problem. Its permanent certificate is requested online and its access code legally replaces the paper certificate; it can be issued in Portuguese or in English. As with civil certificates, no authority on either side publishes how an access-code certificate is treated at the ministry desk, at the UAE Embassy in Lisbon or at MOFA, so for a company file bound for Dubai we establish the acceptable form before anything is ordered.

It is also worth correcting a piece of cross-border folklore, because it is the kind of thing that sounds authoritative and sends a file to the wrong counter. In some countries a chamber of commerce takes over from the usual authority when an export document is bound for a state outside the Convention — Italy works exactly that way, and the rule genuinely surprises people there. Portugal does not replicate it. No Portuguese government source makes a chamber a required step in this route, and the general Portuguese chamber publishes no equivalent carve-out for non-Convention or Arab destinations. If you have been told that a chamber stamp replaces the ministry step for Dubai, that advice has been carried over from a different country's system.

Powers of attorney carry a constraint that logistics cannot remove. Under Portuguese law a power of attorney is granted either by public instrument or by a document written and signed by the grantor with in-person recognition of the handwriting and signature — except where it is granted to a lawyer or solicitador, where that formality does not apply. And simple signature recognition is, in the ministry's own words, always done in person: it can only be performed on a document signed in the presence of the officer. Our doorstep collection and delivery covers documents and the coordination around them. It cannot cover a signature the law requires you to make in person, and we say so at the outset rather than after you have booked.

Translation: Portugal has no sworn translators, and the Arabic step belongs in Dubai

Almost every guide to this corridor tells you to obtain a "sworn translation" in Portugal. Portugal does not have sworn translators. The EU's own justice portal records, on a page whose content Portugal supplies, that Portugal has no database of legal translators or interpreters — it is one of the few Member States with nothing to list.

What Portugal has instead is a certification model, and a Portuguese government agency publishes the full list of who may make or certify a translation: a Portuguese notary, a registrar or registry officer, a lawyer or solicitador practising in Portugal, a recognised chamber of commerce or industry, or a competent translator — whose work must then be certified by one of those authorities. That last item is the one that matters, because it means a translator in Portugal cannot self-certify. What you are buying is a certified translation, and asking for a sworn one is asking for something that does not exist.

At the UAE end the requirement is narrower than most people expect. MOFA asks for the original document in Arabic or English, or else accompanied by a legally certified translation — so a Portuguese document already issued in English, as the criminal record certificate and the commercial registry certificate can be, may need no translation at all. Where an Arabic translation is required, UAE Federal Decree-Law No. 22 of 2022 makes translation a registered and licensed profession, requires registered translators to reside in the country and to practise from within it, and bars authorities from carrying out certification work on a translated document unless the translation came from a translator or translation house on the Ministry of Justice list.

The practical consequence is one of sequence. A translation commissioned in Portugal, however well executed, is unlikely to carry the UAE attestation step, so the Arabic leg is generally best handled here after the document arrives — which is one of the few parts of this process that is genuinely easier from the Dubai end. One related warning: if your Portuguese criminal record certificate comes with the multilingual European model form attached, that form is for presenting documents between EU Member States. It removes nothing for a UAE-bound file — not a translation, not a step.

The Portuguese mission in the UAE is in Abu Dhabi — and it works the other way round

More people search for a Portuguese consulate in Dubai than for anything else in this corridor, so it is worth answering plainly: there isn't one. Portugal's consular network lists a single post for the United Arab Emirates — the Consular Section of the Embassy of Portugal in Abu Dhabi — and its jurisdiction covers the UAE, Kuwait and Iraq. That is not a gap in the listing: the same directory names honorary consulates in other countries where they exist, so the absence of a Dubai entry means what it appears to mean.

The more important point is direction of travel. The Abu Dhabi mission legalises documents issued in the UAE so that they can take effect in Portugal, and it sits at the end of that chain: it requires the documents to have been certified first by the UAE Ministry of Foreign Affairs, after which it recognises the authenticity of the signature on the MOFA stamp. That is the mirror image of what a Portuguese national in Dubai usually needs. If you are holding a Portuguese birth certificate, degree or company document and you need a UAE authority to accept it, the Abu Dhabi embassy is not a step in your process at all.

The confusion is understandable — both missions are real, both legalise documents, and only one of them is on your route. The test is where the document was issued. A document issued in Portugal is dealt with in Portugal and then attested by the UAE Embassy in Lisbon. A document issued in the UAE and heading to Portugal is dealt with here.

How long the Portuguese steps take

We publish the figures the authorities publish, for the steps they publish them for, and we do not add them together — because no authority publishes a time for this chain end to end, and any total would be our invention rather than a fact.

The Portuguese ministry's public desk publishes two figures for its own service, the issuance of its declarations. Where you attend with an appointment booked through its online system, it states the declaration is issued on the spot. Where the request is sent to its Lisbon counter by post, it states the declaration can be collected within five working days of the request reaching that counter. Those are the desk's own figures for the desk's own act, and they are collection and issuance terms rather than a promise about your file as a whole.

The UAE Embassy in Lisbon publishes no turnaround for its counter service, and we will not invent one. What it does publish is more useful in practice: attestation is carried out at the embassy's premises and no prior appointment is required. Since March 2025 the mission has also operated a self-service unit for a digital attestation which it says is ready for download or collection within minutes — a distinct channel with its own eligibility, not a faster version of the counter.

In our experience none of these figures is what actually governs the length of a Portuguese file. What governs it is whether the document exists on paper in the right form, and whether a prior signature recognition is needed. A file that starts with a sealed paper original moves briskly. A file that starts with an access code goes back to the beginning to order a different certificate, and that is the delay worth designing out before anything is collected.

What this process costs

Official fees apply at more than one point. The Portuguese ministry charges a fee for each act performed at its public desks, set by ministerial order. The UAE Embassy in Lisbon charges an attestation fee which varies by document type, and it takes payment by bank card — it does not accept cash. MOFA charges its own attestation fee in the UAE. Where a prior signature recognition or a certified translation is needed, those carry their own charges.

Those are government and third-party charges rather than ours, and they change without notice, so we do not publish figures for them. What we do is quote the official fees and our own service charge separately, so you can see which is which before committing to anything. Send us a photograph of the document on WhatsApp and we will tell you which steps it actually needs — that alone often changes the answer, because a document that turns out to need no translation, or one that turns out to be an access code rather than a certificate, has a very different cost from the one people assume.

What is not published — and why we say so

Most pages on this subject present the Portugal-to-UAE route as though every step were documented somewhere. It is not, and you are better served knowing where the edges are.

Portugal does not publish, in positive terms, what its foreign ministry does for documents bound for countries outside the Hague Convention; its published guidance addresses the Convention route and then stops. The ministry's own desk calls its act the issuance of a declaration rather than a legalisation, and no government on either side has published anything connecting that declaration to the legalisation the UAE Embassy asks for. Neither side publishes how an access-code certificate is handled at these counters. The UAE Embassy in Lisbon publishes no documents checklist and no counter turnaround, and its dedicated attestation page currently carries a heading and nothing else.

None of that makes the route unusable — documents move through it constantly. It does mean the difference between a file that clears and a file that comes back is usually a judgement call made before submission, about the form a document is in and the product a counter will accept. That judgement is what we are actually for. Send a photograph of what you are holding and we will tell you what it needs, including when the honest answer is that a point has to be confirmed with the counter first.
