What is a Sworn Translation? Everything You Need to Know

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. This is true for most sworn translation systems, but not in Italy. In Italy, the translator swears an oath before a court clerk for each individual translation, rather than once at the appointment. 

Once authorised, the translator's stamp and signature are accepted as sufficient proof of authenticity. The sworn translator also takes legal responsibility for the accuracy and completeness of the translation, which is exactly what that stamp represents.

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 has legal authority to translate documents for use in a country other than the one where the document was issued. That authority comes from a court or government body, not the translator’s claim of competence. 

This status gives sworn translators the right that other translators don’t have. Their translations are admissible in court, accepted by government registries, and cannot be replaced by work from an uncertified translator. 

If a sworn translation turns out to be inaccurate or incomplete, the translator who signed and stamped it may face disciplinary action. This includes fines or removal from the official register, since their name and licence number are attached to the translation. 

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;

A notary confirms the identity of the person signing the certification. It does not verify the accuracy of the translation itself, so a notarised translation is not automatically a guarantee of quality.

Note: The term “certified translation” means different things in different countries. In countries with a sworn translator system, sworn translators may still refer to their output as 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, though the details vary. 

Italy is an exception. It does not have a national register at all. Below are countries with a sworn translator system, and the local term used;

Germany, France, and Spain aren't just the largest sworn-translation markets by population; they're also, in that order, the three countries we handle the highest volume of sworn translations for (7,734, 7,532, and 6,420 orders respectively). Italy (1,158) and Poland (1,002) round it up to the top five. 

If your destination country appears in the table above, you’re in good hands; it's one of the markets we handle most often.

A smaller group of countries do not operate a court-appointed sworn translator system at all. Instead, they require certified or officially recognised translation, done by a translator approved through a different route.

The UAE is a useful example of how this works in practice. Although it doesn't operate a court-appointed sworn translator system, documents destined for UAE authorities go through the same rigorous, government-recognised pathway through the Ministry of Justice-licensed legal translators. 

Of the UAE-bound legal translations in our order data, 97.6% were translated into Arabic (UAE). This confirms that "legal translation" here carries the same weight as a sworn translation, even though the legal process differs.

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, translated if they are not already in the national language. In countries with a sworn translator system, immigration authorities typically insist on sworn translations of the following documents;

• Passports and 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 prior 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. It also covers witness statements, expert reports, and sworn declarations. 

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. It also applies to intellectual property filings, including patent applications and trade mark registrations. 

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. Registering a marriage abroad or seeking recognition of a foreign divorce is also a common administrative matter that requires sworn translations. 

Of these six categories, visa and immigration applications account for 15.2% of sworn translation orders for which clients told us why they needed one. Official administrative matters (marriage registration, driving licence renewal, property transactions) follow at 8.5%. The others include university applications (4.3%) and legal/court-related requests (4.2%).

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;

1. Identify the target country's requirements: 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.

2. Locate an approved sworn translator: Each country maintains an official register, and using a translator who is not on it will result in your document being rejected. A reputable translation agency, such as Translayte, has direct access to approved sworn translators in the relevant country and produces officially accepted sworn translations. 

3. Prepare and submit your documents: Send clear, complete copies of all documents that need to be translated. For official bodies, originals or notarised copies are often required. Confirm this before you send anything.

4. Allow time for translation and certification: Standard turnaround is 3-7 working days depending on volume and language pair. 29.3% of sworn translation orders we process are marked urgent. Clients ordering sworn translations tend to plan slightly further ahead than average due to the lengthy process involved. Still, if you have a deadline, ask about express services.

5. Receive the certified sworn translation: The sworn translator returns the translated document with their official stamp, signature, and a signed declaration of accuracy. Keep both the original and certified copies safe.

6. 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 requesting authority will advise.

7. Submit to the requesting authority: Confirm the format the authority accepts. Some require originals, others accept certified copies or digital submissions.

8. Check the document when it arrives: Before you submit anything, confirm the following are all present:

• The certification statement

• The translator's stamp and signature

• The translator's full name and registration number

• The language pair they are authorised for

• An explicit reference to the source document

• Binding to a copy of the original

• Clear pagination

• A clear mark showing where the document ends

Some sources state the certification must contain the exact wording "certified and true copy of the original" to be valid. That wording requirement is country-specific. It is not a universal rule, so do not assume it applies to your destination country without checking.

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 that may reflect their professional standing. 

Common factors that influence the price include; 

• Language pair: Less common languages cost more to translate because fewer sworn translators are qualified to work in them.

• Page length or line count: Most sworn translators price by page, and some countries also count lines for official fee purposes

• Urgency: Express turnaround usually costs extra, around 50%-100% more. 

• Official stamp duty: Some countries add a fixed government charge to the translation fee itself. 

• Apostille: This is a separate legalisation fee by the issuing government authority, not the translator.

Translation fee and official fees are separate items 

Always ask your translator or agency to separate the two because they are paid differently. A good example is Italy. Every sworn translation completed in Italy bears a physical Italian revenue stamp (marca da bollo) in addition to the translation fee. 

The rate is €16 per 100 lines of text, roughly every four pages, and it must be affixed to a paper copy. Italian courts do not accept electronic payment of the stamp duty for this purpose. The tribunale sets this fee, not the translator. For an accurate estimate of your specific document, upload it to get a free quote.

To put it in perspective, whole-order median values for sworn translations we process are £65.00 for Spain, £57.16 for Italy, £54.18 for Germany, £49.12 for Poland, and £39.02 for France. These are the totals per order, not per-page rates, since document length varies.

Digital and electronically signed sworn translations

Digital sworn translation is legally valid for official use. But not all countries accept them. Spain and Brazil are the exceptions. Under AUC/213/2025, published in the BOE on 7 March 2025, Spain regulates the use of a qualified electronic signature for certifying sworn translations. 

Before this order, whether a digitally signed sworn translation was accepted was left to the receiving body’s discretion. Now, a qualified electronic signature substitutes for a handwritten signature and a physical stamp, and the signed document can be verified through Spain's official signature validation service, VALIDe.

Brazil allows sworn translators to complete their work electronically under Lei 14.063/2020.

Italy is the opposite case. Because every sworn translation there requires a physical revenue stamp affixed to the paper, a fully digital sworn translation is not possible as it is in Spain or Brazil.

Even where digital sworn translation is legally valid, confirm that the receiving authority accepts it before you choose digital-only. If you are submitting in person, order a physical copy as a backup.

Sworn translation and apostille: which comes first

A sworn translation and an apostille are two different things. The translation is completed and certified by an authorised translator. An apostille is a separate legalisation stamp, issued by a government authority, that authenticates the origin of a document for use in another country that is a signatory to the Hague Convention.

The order in which you receive them depends on the destination authority and varies by country.

• Some authorities require the original document to be apostilled first, then translated.

• Some want the apostille applied to the translation itself, after it has been completed and signed.

• Some want both the original and the translation apostilled.

Most of the time, the sequence is that the original document is apostilled first, then translated. 

Nonetheless, before ordering either service, confirm the steps as required by the receiving authority. Their answer determines the order you should follow. Translayte offers apostille services for your destination country, based on the required sequence. 

In practice, only 1.1% of sworn translation orders also require an apostille (compared with 0.73% of all orders). Most sworn translations don't need one attached at all. But when they do, getting the sequence right is more important.

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, and verification happen at the Landgericht (regional court) level in each state.

• Italy: There is no national register of sworn translators. Any competent third party may swear a translation, provided they are not the subject of the document. To swear a document, the translator or third party must appear in person at the Ufficio Asseverazioni of a tribunale and sign a verbale di giuramento before a court clerk. In practice, it differs locally. Some tribunali also require registration on the CTU list or with the local chamber of commerce, which is why the requirements differ across Italian cities. 

• Brazil: The profession is now governed by Lei 14.195/2021, which revoked the older Decreto 13.609/1943 and moved the framework to a nationally standardised system. All while keeping the concurso público (public examination) administered through the Juntas Comerciais (state boards of trade). 

• Poland: Sworn translators, tłumacz przysięgły, are appointed after passing a Ministry of Justice examination and are listed on the Ministry's national register.

How to find a verified sworn translator

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 finding individual translators directly.

How Translayte can help

What to do if a sworn translation is rejected

If your translation is rejected, it is usually as a result of any of these reasons; 

• The translator is not on the destination country's register: this is the most common reason. The solution is to redo the translation with a translator registered in the country where the document will be used, not in the one where you are based. 

• Wrong language direction: Sworn translators are authorised to translate for one language direction. For example, Spanish to English. If that translator translates a document into a different language pair (e.g., English to Spanish), the translation will be rejected. Confirm the translator is authorised for that pair before ordering. 

• Not submitting with the original: Many authorities require the translation to be physically or digitally attached to the original document. Confirm this before submitting the document. 

• Missing apostille: If the destination country requires an apostille and it is absent from your document, it will be rejected. In this case, confirm the right sequence of legalising your documents and follow it. 

• Expired source document: Some source documents, such as criminal record checks, have a validity period. If the document exceeds that, the translation will be rejected regardless of quality. 

If a translation is rejected, go back to the translator or agency that produced it. Reputable agencies will correct a genuine error at no extra cost.
