This story repeats almost every week. American client, partner married to a Spaniard, immigration appointment in Aluche on Thursday for an EU family member card. He shows up with his FBI background check already translated — paid 240 dollars to a Texas agency that markets itself as "certified translation services for Spain visa". The document looks the part: thick paper, blue agency stamp, signed accuracy statement from the translator.
The clerk rejects it at the window. No discussion. Hands him half a sheet listing the requirements with the words "sworn translation by translator accredited by MAEC" circled in pen.
He loses the slot. The next available is five weeks out. He has to pay for the translation again — this time by an actual Spanish sworn translator — and hope it arrives in time. Total damage: around 350 dollars down the drain and over a month delay on his residency.
This isn't an isolated incident. It's the incident. We see it nearly every week, almost always with the same handful of agencies that aggressively target Americans moving to Spain.
If you're reading this before you've paid anyone, congratulations — you saved yourself the headache. Here's what's actually going on.
The trap starts in the word "certified"
The word certified sounds official. State-regulated. Backed by some body. In the US, it isn't.
In the US — same in the UK, Canada outside Quebec, Australia, most of the English-speaking world — a certified translation means basically this: the agency or translator attaches a signed page that says "I certify this translation is accurate". It's called a certificate of accuracy. That's it. No state exam, no government registry of who is allowed to do this, no ministerial license.
There is the ATA (American Translators Association), which is a private trade association. Their certified translators have passed an ATA exam. Useful credential in the US market. Recognized by the Spanish state? No. The ATA has no standing under Spanish law. Their credential carries no weight at a Spanish ventanilla.
Spain handles this differently. The role exists and is locked down by law.
How Spain's sworn translation system actually works
Two pieces of legislation matter:
- Law 2/2014 of 25 March, the Foreign Action and Service Act, additional provision sixteen — establishes the professional accreditation of sworn translator-interpreters.
- Royal Decree 724/2020 of 4 August, approving the Regulation of the Language Interpretation Office.
The 2020 Royal Decree spells out the operational details: how accreditation is obtained (an annual state-run exam through the MAEC, one language pair at a time), what the stamp must contain, what the certification statement must say, and the validity of electronic format.
The reason a foreign certified translation cannot substitute: in Spain, the accreditation is personal and non-transferable. It's tied to a specific human being, with an accreditation number, listed on a public registry anyone can consult on the MAEC website. The certifier isn't an agency — it's an identifiable translator with personal civil and criminal liability over what they sign.
When a Spanish civil servant looks at your translation, they check three things: is there a stamp? does the stamp carry a MAEC accreditation number? does the name match the official list? Three yes-es and they accept it. One no and they reject. Quality of the translation doesn't enter the conversation.
What happens at each Spanish administration
Not every counter behaves the same. Here's the realistic breakdown by use case.
Immigration offices — Oficinas de Extranjería (visas, NLV, DNV, family reunification, EU citizen family member card). Near-certain rejection. Clerks at the big offices — Aluche in Madrid, Marqués de Sotelo in Valencia, Barcelona Mallorca, Murcia — recognize a US agency stamp on sight. Smaller offices occasionally let one slip through with a distracted clerk, but it's not a strategy — you're betting your appointment on a coin flip.
Civil Registry — Registro Civil (marriage, birth registration, death registration). Rejection. Especially strict here because they're recording civil status. No registrar wants to inscribe based on an unofficial translation.
Notaries — Notarías (power of attorney granted by a foreigner, inheritance, real estate purchase). Depends on the notary. Some accept it if they know the client and the transaction is simple. Most reject it because, if there's later challenge, admitting a non-official translation is on them.
MAEC for apostille. Automatic rejection and quick. The MAEC is the same ministry that issues the sworn translator list. They will not apostille a translation that they themselves don't recognize.
Universities and degree recognition (Ministry of Universities, UNED, ANECA). Rejection. Trained staff handles this filter specifically.
Courts. Rejection in any procedure where a foreign document must be filed translated. And if it somehow gets in at first instance, opposing counsel will challenge it the moment they see it.
The one caveat: occasionally a small town hall, a local agency, a low-traffic counter, will accept it. That doesn't mean it was valid. It means the clerk wasn't looking carefully. If that file moves up the chain, it gets bounced back.
What this mistake actually costs
Real numbers from real cases, with realistic ranges.
- US certified translation: 180 to 350 dollars for a standard document, depending on agency.
- Your time arranging the US translation: a week of back-and-forth emails.
- Wait for Spanish immigration appointment: four to eight weeks for a slot.
- Rejection at the counter: instantaneous.
- Next available appointment: another two to six weeks depending on city.
- Spanish MAEC sworn translation, urgent turnaround: 80 to 200 euros depending on document.
- Stress: uncountable.
Multiply if your procedure had a deadline (legal entry within visa window, renewal, court filing). Add the family factor — couples who'd lined up a June arrival having to push everything to a September lease.
We've seen cases where the client paid three times for the same translation: the original US certified, a second one at another US agency because they thought "the first was bad quality" (it wasn't bad, it just wasn't the right legal figure), and finally a proper Spanish sworn translation.
What a valid Spanish sworn translation must contain
If you're commissioning a sworn translation, this is what the translator must deliver. Worth knowing before you pay.
- Translated text in Spanish. Certification statement also in Spanish. If your translator delivers the certification in English "because the client is American", something's wrong — the regulation requires Spanish.
- Every page signed and stamped. The stamp contains the translator's full name, MAEC accreditation number, language pair (for example "INGLÉS-ESPAÑOL"), and an identifier.
- Final certification with the regulated wording. Something along the lines of: "Doña/Don [name], Sworn Translator-Interpreter of [language] appointed by the Ministry of Foreign Affairs, European Union and Cooperation, certifies that the foregoing is a faithful and complete translation into Spanish of a document drafted in [language]. In [place], on [date]". Then signature and stamp.
- A copy of the original attached, also stamped on every page. Easy to miss: the original document must travel with the translation, with the sworn translator's stamp on each of its pages too. This is what legally binds original and translation.
- In PDF: qualified electronic signature. Since the MAEC Resolution of 26 July 2020, a sworn translation delivered as PDF and signed with a qualified electronic certificate (one that complies with EU Regulation 910/2014, eIDAS) has exactly the same legal weight as the paper version. No asterisk. If someone tells you "the PDF isn't accepted" they're working off pre-2020 information.
Missing any of these five and the document is defective — irrespective of who issued it.
Verifying a Spanish sworn translator in thirty seconds
This is the check you do yourself, from your phone, before paying anyone.
- Go to the Spanish Ministry of Foreign Affairs (MAEC) website. Search for "lista traductores intérpretes jurados".
- The MAEC publishes a searchable directory by language pair and Spanish autonomous community. Filter for your combination (English to Spanish, for example).
- You get a PDF or search interface listing every accredited translator with full name, accreditation number, and the province where they're registered.
- Ask the translator or agency you're contracting with for the full name and accreditation number of the sworn translator who will sign your document.
- Confirm they appear on the list.
If the agency dodges giving you a name, red flag. If they say "we work with several sworn translators, we can't confirm which one yet", that's reasonable — but they must confirm before delivery, and it must match the stamp you receive. If you only get a brand name, no individual person, it's not a valid sworn translation under Spanish law.
Can a certified translation be "upgraded" to sworn?
Honestly, almost never worth the trouble.
The technical reason: when a sworn translator stamps a document, they take on personal civil and criminal liability for the fidelity of the text. To accept that liability they have to review the document fully, cross-check against the original, and effectively rewrite where any nuance shifts. That's why what's billed as "review and swearing of pre-existing translation" usually runs at 70 to 100% of a fresh translation. You don't save much and you introduce risk: if the sworn translator finds discrepancies between original and certified version, they have to fix them, which adds time.
Our standard advice when clients send us a certified translation and ask if we can swear it: don't waste time, send us the original, we'll do a fresh sworn translation in four or five business days. Same cost or less than patching the old one, no headaches.
Reverse direction: Spanish sworn translation used abroad
Common question, especially from Spaniards relocating or from internationals leaving Spain with documents in hand.
Generally yes, it travels well. A Spanish sworn translation carries certification and stamp identifiable enough to pass as "translation with certificate of accuracy" in US contexts. For USCIS filings the Spanish sworn translation, apostilled, is typically accepted. Some procedures may additionally ask for a notary public stamp — that's a layer added on top, it doesn't replace your sworn translation.
For the UK, similar pattern: a Spanish sworn translation is usually accepted for settled status, NHS and consular procedures, often with an apostille. For France, accepted in consulates and prefectures if apostilled, though for purely French internal matters a traducteur assermenté registered with a French cour d'appel still flows more smoothly.
The Spanish system is among the more rigorous in Europe, and that works in favor of anyone leaving Spain with documents: what a MAEC sworn translator signs has comfortable international recognition. The reverse trip — bringing a US or UK certified translation and trying to file it at a Spanish counter — is what doesn't work.
Practical takeaway
If your document is going to be filed in Spain, go straight to a sworn translation with MAEC stamp. No shortcuts.
If your document is going to be filed outside Spain, check the receiving institution first. In the English-speaking world a certified translation generally suffices. Across most of the EU you'll need the local equivalent figure (assermenté in France, beeidigt in Germany, ufficiale in Italy).
If you're not sure: ask before you pay. Five minutes of conversation saves three weeks of correction. We reply on WhatsApp typically within an hour during Spanish business hours, and we'll tell you straight whether what we do is what you need or whether a different figure suits your case better.
