If you are not sure whether your document needs this type of translation, send us a copy and tell us which authority will receive it. Our translation agency in Valladolid can then distinguish between an ordinary professional translation, a Spanish sworn translation and a project that may require additional formalities outside Spain.
Documents commonly translated under the Spanish sworn system
Birth and marriage certificates, criminal-record certificates, degrees, transcripts, powers of attorney, deeds, court judgments, company registry documents and administrative certificates are among the documents we see most often. The list is not exhaustive: the determining factor is usually the requirement of the receiving body, not the document title on its own.
A university may ask for a sworn translation of an academic transcript, while another institution may accept a different form of certified translation. A company file may contain some annexes that need official certification and others that do not. Separating those elements can avoid unnecessary cost.

English and Spanish sworn translations
English is one of the most frequent combinations in official paperwork. Our English-Spanish translation service covers both general and specialist content and explains when a Spanish sworn translation may be the appropriate route.
Typical assignments include academic records, employment documents, company records, criminal-record certificates, birth and marriage certificates and documents connected with residence, work or study. The exact formalities still depend on where the translation will be presented.
Documents for universities and academic procedures
Valladolid has a large university community and regular international mobility. Degrees, transcripts, certificates of attendance, course records and supporting documentation may be required for admissions, credit recognition, postgraduate study, employment or professional registration.
Before translation begins, check whether the institution requires both sides of a certificate, annexes, grade scales or accompanying statements. A missing page or stamp can delay a procedure even when the translation itself is correct.
Company, legal and notarial documentation
Businesses may need sworn translations of powers of attorney, deeds, corporate certificates, court documents, registry extracts or tender documentation. If a file contains technical annexes that do not require certification, we can quote them separately using our technical and industrial translation service rather than applying the sworn process to everything.
This is particularly useful for larger corporate files, where legal, administrative and technical content may sit together in the same dossier.
Digital and paper delivery
The required delivery format depends on the receiving authority, the translator and the procedure involved. Some bodies accept electronically signed sworn translations; others may still ask for a physical copy. We therefore recommend checking the authority's current instructions rather than assuming that one format is universally accepted.
Where a paper copy is needed, we confirm the dispatch arrangement before the job starts. You do not normally need to visit the Valladolid office simply to request a quotation.
Use of Spanish sworn translations abroad
A sworn translation produced under the Spanish system may be accepted abroad, but this should never be taken for granted. Foreign authorities can have their own rules on certification, notarisation, legalisation or apostille requirements.
If the document is intended for another country, tell us which one. We can then ensure that the translation itself is prepared correctly and flag the need for the client to verify any additional formalities with the receiving authority.
How to request a quotation
Send a complete, legible copy of the document, including stamps, annotations and reverse sides that need to be translated. Tell us the source and target language, the country or institution where the translation will be used and any deadline you have been given.
You can request the service through our Valladolid translation services or contact LinguaVox directly. We confirm the price and expected delivery before starting.
Frequently asked questions
What is the difference between a sworn translation and an ordinary translation in Spain?
A Spanish sworn translation is completed and certified by a sworn translator appointed for the relevant language pair. An ordinary professional translation does not automatically have that official status, even if it is linguistically accurate and produced by an experienced translator.
Do you need the original document?
We can usually prepare a quotation from a clear digital copy. Whether the original document is needed for the wider procedure depends on the receiving authority. Send all pages, reverse sides, stamps and annotations that form part of the document.
Will a Spanish sworn translation be accepted in every country?
Not necessarily. Other countries may require a different form of certification, notarisation, legalisation or apostille. The receiving authority should confirm what it accepts before you order the translation whenever possible.
Can you translate university degrees and transcripts?
Yes. Academic documents are among the most common sworn-translation assignments. It is important to include grade scales, annexes and any additional pages the institution expects to see, not just the front page of the degree certificate.
How long does a sworn translation take?
It depends on the language pair, document length and availability of the appropriate sworn translator. A short certificate can often be handled much faster than a long deed, court file or academic dossier. We confirm the expected delivery date before you approve the quotation.
