Buying a car in Germany, France or Italy and bringing it to Spain still makes sense for a lot of people: more choice, sometimes a better price, a model that never officially arrived here. What tends to catch buyers off guard isn't the drive home — it's the paperwork afterwards. And within that paperwork sits one very specific question we get asked all the time: do I have to get a sworn translation of the vehicle documents for the DGT or the ITV? The honest answer is "it depends on the document" — and much of the surprise is a pleasant one, because there's one document you almost never need to translate.
The Certificate of Conformity (CoC): the good news
The European Certificate of Conformity — the CoC — is the document that certifies your vehicle was built to a type approved in the European Union, under the EU vehicle type-approval framework. In practice it's the car's technical identity sheet, recognised across the whole Union: chassis number, weights, emissions, dimensions, vehicle category and so on.
The point that matters for anyone importing is how it's written. The CoC of a car approved at European level is, by design, a harmonised and largely multilingual format: the headings and field labels typically appear in several official EU languages already — Spanish included — and the data filling the boxes is mostly figures and shared codes. That's why, in most registrations of a car bought in another EU country, the harmonised CoC doesn't need a sworn translation: the Provincial Traffic Office (Jefatura de Tráfico) reads it as it is.
Here's the honesty that matters to us: if your CoC is the standard European one and already includes Spanish among its languages, don't let anyone sell you a translation you don't need. Over-translating is wasted time and money.
When the CoC can be a problem
The nuance lives in the word harmonised. Not every sheet that says "Certificate of Conformity" is the multilingual European CoC. A vehicle approved on an individual basis, a model originally imported from outside the EU, or a certificate issued in an old format or only in the country-of-origin language no longer fits that comfortable case. If your CoC is not the multilingual European format and arrives written solely in German, French or Italian, it's reasonable for the authorities to ask for a sworn translation into Spanish before they'll process it.
Put another way: what decides it isn't the document's name, but whether it comes in a format the Spanish administration can read directly.
The other vehicle documents: here you usually will need one
The CoC is only one piece of the file. To register in Spain a car that was already registered in another EU country, other papers come into play — and these tend to be written in the country-of-origin language only:
- The foreign registration certificate (the French carte grise, the German Fahrzeugschein/Zulassungsbescheinigung, the Italian libretto di circolazione). It's the registration title from the country of origin.
- The purchase invoice or the sale contract, especially for settling the corresponding taxes.
- Deregistration or export certificates from the country of origin, where they apply.
These documents are rarely multilingual. When the administration needs to read them to verify ownership, specifications or the taxable event, it commonly requires a sworn translation into Spanish produced by a translator authorised by the Spanish MAEC (Ministry of Foreign Affairs). A courtesy translation, your own version, or one without an official stamp won't do for these purposes.
Before you order anything: ask exactly what's required
Time for a frank note. The specific registration requirements — which documents you must submit and which must be translated — are set by the DGT / Jefatura de Tráfico and the ITV station handling your case, and they can vary with the vehicle type, its origin and the approval route. Before ordering a single translation, confirm with the Traffic Office (or the agent handling the process) the exact list of documents they'll want translated. It's the surest way not to translate too little — or too much.
One related point worth keeping clear is the difference between apostille and translation: they're separate things and don't always go together. Within the EU, between public documents, an apostille often won't be needed; if it does come up in your case, we explain how it fits with the translation in our guide to the Hague apostille and sworn translation.
Where Textualia fits in
Our part is simple and bounded: when a sworn translation of your car's documents really is needed — the registration certificate, the invoice, or a non-harmonised CoC — we produce it with the stamp of the translator authorised by the MAEC that the Spanish administration expects, delivered as an electronically signed PDF. And if your CoC is the multilingual European one and needs no translation, we'll tell you: we'd rather have a customer who comes back than one who over-translates.
If you'd like, before ordering you can check that your translator is authorised by the MAEC.
