A company orders a certified translation of its articles of association, pays for it, receives the document with the certificate signed by a lawyer, and weeks later the receiving authority rejects it. The reason is rarely translation quality. It is usually a formal requirement nobody checked before placing the order.
This happens more often than it should, particularly when the document is going abroad or to a public body with its own rules. The fix exists, but it happens before the order is placed, not after the rejection letter arrives.
Ask the receiving authority, not the translation provider
The first check is not with the translation company. It is with whoever will receive the document. A notary's office in São Paulo, a university in London, a court in Luanda and an HR department in Berlin can all have different requirements for what looks like the same type of certificate.
Before requesting a quote, the applicant should get clear answers to three specific questions from the receiving authority:
- Does it accept a certified translation produced in Portugal, or does it require a sworn translator registered locally?
- Does it require an apostille or consular legalisation on the original document, on the translation, or on both?
- Does it have a specific certificate format, or does it accept the standard format used in the country of origin?
The answers to these three questions shape everything that follows. Without them, any translation ordered is a gamble.
Understand what "certified" means in each country
Portugal has no sworn translation. A certified translation is authenticated by a lawyer registered with the Portuguese Bar Association or by a notary: the translator declares before one of these that the translation is faithful to the original, and both sign the certificate. This is the model most Portuguese authorities and many foreign ones accept, but not all of them.
In Angola, authentication is carried out by an Angolan notary, and the concept of sworn translation does not apply there either. Brazil and Spain, along with France, Germany and Italy, do have sworn or assermenté translators registered with an official local body. If the document's final destination is one of these countries, it is worth confirming whether the authority accepts a certified translation produced in Portugal or specifically requires a translator sworn in that country.
This distinction is the most common cause of rejection in court proceedings, covered in more detail in sworn translation for court documents, and in employment processes for expatriate staff.
Check the apostille, legalisation and validity window
The Portuguese apostille is issued by the Procuradoria-Geral da República (PGR), for any type of document, and it applies when the destination country is party to the Hague Apostille Convention. When the destination is not party to that convention, a different process applies: legalisation by the Ministry of Foreign Affairs, followed by legalisation at the destination country's embassy or consulate.
Angola and Mozambique are not party to the Hague Apostille Convention. A Portuguese document destined for Angola goes through classic consular legalisation, never an apostille. For foreign documents entering Angola, legalisation happens in the country of origin, with authentication by that country's own ministry of foreign affairs followed by legalisation at the Angolan consulate there. MIREX, Angola's Ministry of Foreign Affairs, works in the opposite direction only: it legalises Angolan documents destined for use abroad, not foreign documents entering Angola.
Beyond legalisation, two practical points often get missed until it is too late:
- Validity window of the certificate: some authorities only accept certified translations issued within the last three to six months.
- Order of operations: in some cases the apostille needs to be on the original document before translation; in others, the translation itself needs its own apostille. This order changes depending on document type and destination country, so it is worth confirming it with the receiving authority before starting any step.
Get confirmation in writing and keep it
A phone call is not enough. Requesting confirmation by email, with the authority's name, date and specific requirement, gives the applicant a record to produce if the document is questioned later, and also gives the translation provider accurate information to work from.
That full picture, the certification format required, whether apostille or legalisation applies, the validity window, any specific certificate template, should accompany the quote request. An experienced legal translation provider will ask for these details if the client does not supply them first. If they do not ask, treat that as a warning sign.

Frequently Asked Questions
How do I know if the receiving authority accepts a certified translation from Portugal?
The only reliable way is to ask the receiving authority directly before ordering the translation, since requirements vary between countries and even between authorities within the same country.
Does an apostille always apply to certified translations?
No. The apostille only applies when the destination country is party to the Hague Convention. For countries outside that convention, such as Angola and Mozambique, consular legalisation is the correct process instead.
What is the difference between certified and sworn translation?
Portugal and Angola have no sworn translation: the translation is certified by a lawyer or notary. The term sworn correctly applies to Brazil, Spain, France, Germany and Italy, countries with a registered sworn or assermenté translator system.
Who issues the apostille in Portugal?
The Portuguese apostille is issued by the Procuradoria-Geral da República (PGR), for any type of document.
What should I do if the receiving authority will not confirm its requirements?
In that case, follow the most common certification format for that document type and country, request written confirmation from the translation provider on that choice, and keep the record in case the process needs to be justified later.
