Sworn translation of documents
What is a sworn translation, who can do it, and what documents does it cover
A sworn translation is the only type of translation that has full legal recognition before public bodies, consulates, embassies, notaries, courts, and administrations in any country.
The difference from a normal translation is not one of quality but of legal backing: a sworn translation is signed and sealed by a sworn translator registered in the official list of sworn translators of the MAEC—the Ministry of Foreign Affairs, European Union and Cooperation—, which makes the document a legally binding instrument before any institution that requires it.
Who can perform a sworn translation in Spain?
In Spain, only professionals who have passed the MAEC's aptitude exam or have obtained accreditation through an recognized alternative route can perform official sworn translations.
Their name appears in the list of sworn translators of the MAEC, which is public and consultable. Any document bearing the signature and seal of an accredited sworn translator on that list has automatic legal validity before any Spanish or foreign body that requires it.
MC LEHM express translators are registered in the official list of sworn translators and issue documents with signatures and seals in accordance with current regulations.

This collection includes two products that cover everything else: sworn translation of letters and sworn translation of other documents.
Sworn translation of letters
A sworn translation of a lettercovers any written communication with official value or that must be presented before an official body: invitation letters for visas, sponsorship letters, acceptance letters from foreign universities, communications from public bodies, letters from financial institutions, and any other type of official correspondence that the recipient requires in sworn translation format.
Many of these letters accompany visa applications, family reunification processes, or residency procedures where supporting documentation must also be certified by an official sworn translator.
At MC LEHM express, we deliver sworn letter translations starting from €19.95 within 24 hours with digital signature and seal.
Sworn translation of other documents
The Other documentsproduct is designed for any document that does not fit into any of the other categories, such as:
- Technical manuals accompanying product approvals
- Corporate texts that are part of international administrative files
- Institutional communications
- Meeting minutes with legal value
- Certificates of all types not covered in the other collections
- Any other document for which the receiving body requires an official sworn translation.
The base price starting from €27.95 reflects that these documents often have greater length or complexity than standard ones.
Price, deadlines, languages, and how the online sworn translation service works
How much does a certified translation cost?
The price of certified translations at Mc LEHM express starts from €17.95 for documents of standard single-page length.
For letters, the base price starts from €19.95, and for special or variable-length documents, from €27.95.
The price of certified translations depends on three factors: the number of pages in the original document, the target language, and the requested delivery time.
In which languages are certified translations provided?
At Mc LEHM express, we provide certified translations between Spanish and the most requested languages: English, French, German, Italian, Portuguese, Arabic, Russian, Dutchand others.
If you need a certified translation in a language not listed in the options, please contact us: the team of certified translatorsat Mc LEHM express covers more combinations than those shown in the standard catalog. Consult other languages.
How does the online certified translation service work?
The entire process is digital. The client chooses the product, uploads the document in PDF, selects the target language, and confirms payment.
The team of official certified translators at Mc LEHM express processes the order and delivers the certified translation in PDF with a digital signature and sealdirectly to the client's email within the agreed timeframe.
The certified translation with a digital signature has the exact same legal validity before any institution as the paper version: consulates, embassies, notaries, courts, civil registries, universities, and public administrations accept it without distinction of format.
What is the validity of online certified translations?
An online certified translation has exactly the same legal validity as any certified translation delivered on paper. The validity does not depend on the format —paper or PDF— but on who signs it: a certified translator registered in the official list of the MAEC with their seal and declaration of fidelity to the original.
This is the guarantee required by any receiving body, and it is exactly what every delivery from Mc LEHM express includes. The validity has no intrinsic expiration date, although some organizations may require that the original translated document was issued within a certain period before presentation.
Frequent errors, common questions, and use cases for the service
What is the difference between a sworn translation and a regular translation?
The difference is legal, not one of quality. A regular translation may be excellent, accurate, and professional, but it does not have legal backing before any public body.
A sworn translation is one carried out and signed by a sworn translator registered in the official list of the MAEC and is the only one that has legal validity before administrations, consulates, notaries, and courts. When an entity asks you for an official translationof a document, what it always requires is a sworn translation: not a certified translation without official accreditation, not a translation carried out by a professional not registered with the MAEC, and certainly not an automatic translation.
Submitting any of these alternatives will result in the rejection of the document and require repeating the process from the beginning.
Can a sworn translator translate any type of document?
Yes. A sworn translatorauthorized by the MAEC can sign the sworn translation of any written document, regardless of its nature or category.
There are no legal restrictions on the type of document. What does exist is practical specialization: the terminology of an employment contract, a medical report, a university degree, or a tax certificate are distinct from each other and require the sworn translator to have mastery of that specific terminology.
At Mc LEHM express, assignments are given to the sworn translator on the team who specializes in the subject matter of the document, regardless of whether the document is standard or atypical.
