What is a sworn translation?
A sworn translation is a legally certified translation of an official document, completed by a translator who has been formally authorised by a court or government authority in the country where the translation will be used. The sworn translator adds their signature, official stamp, and a signed declaration confirming the translation is complete and accurate.
The word 'sworn' refers to the oath the translator swears before a court at the point of authorisation, not an oath they take with each translation. Once authorised, the translator's stamp and signature are accepted as sufficient proof of authenticity.
Sworn translations carry the highest level of legal standing in the countries that use them. They are accepted by courts, government ministries, immigration authorities, universities, and employers as genuine and accurate versions of the original documents.
Who is a sworn translator?
A sworn translator is someone who has the authority to provide sworn translations of important legal documents that have been provided in a language which is not the official language of that country.
The term ‘sworn translator’ comes from the fact that the translator must swear an oath before a national court. However, in some countries, the term “sworn translator’ simply means the translator swears before a court, or lawyer that the translation he/she has completed is a true version of the original.
All sworn translations completed by sworn translators are accompanied by the signature of the translator and a stamp or seal certifying that it has been translated by a sworn translator.
Sworn translation vs certified translation vs notarised translation
These three terms are often used interchangeably, sometimes even by the authorities requesting them. But they are not the same thing. Let’s look at their differences;
| Sworn translation | Certified translation | Notarised translation |
|---|
What it is | Translated by a court-authorised sworn translator who adds a stamp and signed declaration | Translated by a professional translator who signs a statement of accuracy | Translation signed before a notary or lawyer who witnesses the translator's oath |
Who authorises it | Court or government body | The translator themselves (or a national body, e.g. NAATI in Australia) | A notary or lawyer |
Common countries | Germany, France, Spain, Italy, Netherlands, Brazil, Poland and most of Europe and Latin America | USA, UK, Australia, Canada (and many countries that do not have sworn translator systems) | Some Latin American countries |
Legal standing | Highest. It is recognised by courts and government bodies | Widely accepted; level of trust varies by country | Adds witness layer; does not verify translation quality |
Typical uses | Visa applications, court documents, degree recognition, official registrations | Immigration (USA, UK, Australia), employment, university applications | Immigration (USCIS), legal proceedings |
Note: The term “certified translation” means different things in different countries. In countries that have a sworn translator system, sworn translators may still call their output a 'certified translation'. Always confirm exactly what the requesting authority needs.
Which countries require sworn translations?
Sworn translation is most common in Europe and Latin America. Most countries in these regions have formal registers of sworn translators and will only accept translations produced by authorised translators on those registers. These countries include;
When do you need a sworn translation?
The type of document, and the country you are submitting it to, will determine whether you need a sworn translation or whether a certified translation will do.
1. Visa and immigration applications
Almost every country requires supporting documents for visa and residency applications, and most require translations of documents not in the official national language. In countries with a sworn translator system, immigration authorities typically insist on sworn translations of your Passports, national identity documents, birth, marriage, divorce, and death certificates, criminal record checks, medical reports, financial records, and bank statements.
2. Employment documents
If you are applying for a job abroad and your qualifications or employment history are in a different language, some employers, and professional licensing bodies, will require sworn translations of your degree certificates, professional accreditations, and employment references.
3. University and study applications
Many European universities require sworn translations of previous academic qualifications for non-native language applicants. This is common for master's and doctoral applications, and for programmes taught in a language other than your own.
4. Court proceedings and legal documents
For use in legal proceedings, any document submitted to a court in a language other than the court's official language will generally need a sworn translation. This includes evidence, contracts, company documents, and case histories.
5. Corporate and business registrations
Setting up a business, registering a patent, applying for professional licences, or submitting financial documents to a foreign regulator typically requires sworn translations. This applies to balance sheets, articles of association, and regulatory filings.
6. Official administrative matters
Renewing a driving licence abroad, registering a property, applying for healthcare access, or completing official government registrations may all require sworn translations of supporting identity and personal documents.
How to get a sworn translation: Step by step
The process is straightforward if you know what you need before you start. Here are the steps to follow;
Identify the target country's requirements. Always check with the authority you are submitting to if they need a sworn translation (not just a certified one) and whether they have any specific format requirements.
Locate an approved sworn translator. Each country maintains an official register. Contact a reputable translation agency like Translayte, with access to approved sworn translators in the relevant country. This avoids the risk of using someone who claims to be authorised but is not on the register.
Prepare and submit your documents. Send clear, complete copies of all documents that need translating. For official bodies, originals or notarised copies are often required. Confirm this before you send anything.
Allow time for translation and certification. Standard turnaround is 2-4 working days depending on volume and language pair. If you have a deadline, ask about express services.
Receive the certified sworn translation. The sworn translator will return the translated document with their official stamp, signature, and a signed declaration of accuracy. Keep both the original and certified copies safe.
Attach an apostille if required. If the document needs to be recognised in another country that is a signatory to the Hague Convention, you may need an apostille attached. Your agency or the authority requesting the document will advise.
Submit to the requesting authority. Confirm the format the authority accepts. Some require originals, others accept certified copies or digital submissions.
How much does a sworn translation cost?
Cost varies by country, language pair, document length, and urgency. Sworn translators in countries with formal registers charge rates set partly by their professional standing. Nonetheless, you can expect to pay €40–€110 per page for sworn translations. For a more accurate estimate, upload your document for free.
Note: Apostille fees (where needed) are separate and charged by the government authority issuing them.
How sworn translators are authorised
Sworn translator systems vary by country, but the principle is consistent: translators must demonstrate language and translation competence and then formally swear an oath before a court or government authority.
Spain: Translators pass an exam set by the Ministry of Foreign Affairs (MAEC) before receiving the title of traductor jurado (sworn translator)
France: Applicants undergo a rigorous vetting process and are called to swear an oath at the Cour d'Appel (Court of Appeal). Only a small number are admitted each year
Netherlands: The Bureau Wbtv maintains the national register under the Sworn Interpreters and Translators Act (Wbtv). Translators must complete character and ability checks before swearing an oath at their district court
Germany: Each federal state (Bundesland) maintains its own register of sworn translators (beeidigte Übersetzer). Authorisation is granted at state level
This formal authorisation process is why sworn translations are trusted by government bodies and courts. It is not straightforward to become a sworn translator, and the system is designed to ensure only qualified, vetted professionals can provide these legally significant services.
How to find a verified sworn translator
When you need a sworn translation, the translator must be approved by the relevant authority in the country where the translation will be used, not just where you are based.
Official registers to check by country:
Spain: Ministry of Foreign Affairs (MAEC), search the official traductor jurado list
France: Contact the Cour d'Appel for the relevant region
Netherlands: Bureau Wbtv national register (bureauwbtv.nl)
Germany: The Landgericht (regional court) in each federal state maintains its own list
Before commissioning a sworn translation, confirm:
The translator is on the official register for the destination country
They are authorised for your specific language pair (translators are typically approved only for one direction, e.g., English into Spanish, not Spanish into English)
They understand the specific requirements of the authority you are submitting to
Working with a translation agency that has established relationships with approved sworn translators in multiple countries is often faster and more reliable than trying to find individual translators directly.
