The Hague Apostille is convenient: a single stamp and your document is valid abroad. The catch is that not every country in the world is in the Convention. When yours is not, the apostille simply does not exist for that document, and an older, longer procedure takes its place: legalisation through diplomatic channels, also called consular legalisation. Here is what it involves and where the sworn translation comes in.
Why the apostille does not work for some countries
The Hague Convention of 1961 abolished the legalisation requirement only between the countries that sign it. As of 30 June 2026 there are 130 Contracting Parties, and the list grows every year: Canada joined in 2024 and China in 2023, for example. But a fair number of countries remain outside — mainly in Africa, the Middle East and parts of Asia: Egypt, the United Arab Emirates, Qatar, Kuwait, Iraq, Nigeria or Kenya, among others.
If your document was issued in one of those countries, no apostille will be placed on it, because the issuing country is not part of the system. Note: the United States, the United Kingdom, France, Germany, Italy and now Canada too are inside, so for those the route is the apostille, not consular legalisation. You can check who apostilles in each country in our country-by-country table for 2026. This article is for everything else.
The consular legalisation chain, step by step
Where the apostille is a single stamp, diplomatic legalisation is a chain of stamps, each one validating the signature before it. For a foreign public document you want to file in Spain, the usual path is:
- The authority that issues the document in the country of origin (civil registry, court, notary, university…). Sometimes there is a prior internal step to recognise the signature.
- The Foreign Ministry of that country, which legalises the signature of the authority above.
- The Spanish Embassy or Consulate in that country (the mission covering that consular district), which legalises the local ministry's stamp.
- The Legalisation Section of the Spanish Ministry of Foreign Affairs (MAEUEC) in Madrid, when the procedure requires it to close the chain.
Each link confirms that the previous one is genuine. That is why you cannot skip the order: a Spanish consulate does not directly legalise the signature of the official who issued the paper, but rather the stamp of that country's Foreign Ministry.
Where the sworn translation comes in
As with the apostille, the golden rule is legalise first, translate afterwards. Once the document comes back to you with the full chain of consular stamps, then — and not before — it goes to the sworn translator.
And here is a detail many people overlook: the sworn translation is not limited to the original text; it also covers all the legalisation stamps and endorsements added along the way. They are part of the document, and the Spanish administration wants to read them in Spanish. If you translated before legalising, you would have to return to the translator to add those stamps: double work and double turnaround. The translation is signed and stamped by a translator authorised by the MAEC, who certifies the fidelity of the whole.
Exceptions: when legalisation is not needed
Not every document from an "outside" country carries the full chain. Some conventions exempt certain documents from legalisation, and it is worth checking before you start:
- Bilateral agreements between Spain and specific countries that remove legalisation for particular document types.
- ICCS conventions (International Commission on Civil Status), such as those allowing multilingual civil-status certificates without legalisation.
- EU Regulation 2016/1191, which exempts many public documents circulating between European Union countries from legalisation and apostille.
If your case fits one of these, you can skip the consular route entirely. When in doubt, the sensible step is to check with the Spanish body where you will file the document.
Plan with time to spare
Let us be honest: consular legalisation is slower than an apostille. Several administrations in two countries are involved, each with its own timelines, counters and sometimes prior appointments. It is not unusual for the process to run into weeks. So if you know your document comes from a non-signatory country, start early and leave a margin before any deadline.
Once the document is legalised, the translation is the fast part. At Textualia we always start from the already-legalised document and translate the original together with all its consular stamps in a single order, ready to file with the administration.
