When do you need a sworn translator?

What is a sworn translator in France?

A sworn translator is a translator-interpreter registered as a court-appointed expert in branch H — Interpreting and Translation — on the list drawn up each year by one of the thirty-six French courts of appeal. Registration is first for a three-year probationary period, then for renewable five-year periods. A sworn translator can appear on only one court of appeal list.

This court-appointed expert status is what allows a sworn translator to add to a translation the certification statement, their stamp and a unique registration number. These three elements give the translation its evidential value before a French authority.

Being a sworn translator is not the same as mastering a foreign language. A non-sworn professional translator can handle a commercial contract, a website or a technical report. Conversely, sworn status attests to a judicial authorisation, not to a sector specialisation.

Key point — a sworn translator is a court-appointed expert registered on the list of a French court of appeal, for three years and then for five-year periods.

The reasons for rejection we see most often

Among the files that reach the Directory of Sworn Translators of France after an initial rejection, the main reason is almost always the same: the translation was made abroad, by a translator who is not registered on any French court of appeal list. It may be flawless in substance, but it does not have the required status, and the authority rejects it without examining its content.

Next comes the age of the source document. Many procedures require a document less than six months old, sometimes less than three. The rejection then concerns the date of the document, not the translation — but everything has to be done again: a new document, a new translation.

The third reason: no apostille on the source document. Be careful, however, not to request one unnecessarily. For civil status documents issued in one EU Member State and presented in another, the apostille has no longer been required since February 2019.

Two points of vigilance concern us directly. Handwritten documents are our main source of errors: we always have them double-checked, particularly identification numbers. And we regularly see documents coming back whose marginal notes were omitted — they are an integral part of the document and must appear in the translation.

When is a sworn translation mandatory?

A sworn translation is required whenever a document in a foreign language is presented to a French authority. The three families of files below account for most requests.

Civil status and immigration: birth, marriage and death certificates, family record books, certificates of capacity to marry, divorce judgments, passports, criminal record extracts, driving licences, proof of address. These documents make up naturalisation, residence permit, visa, family reunification and French civil registration (transcription) files.

Studies and employment: diplomas, transcripts, certificates of achievement, certificates of enrolment, employment certificates, payslips. These documents are requested by French universities, schools and employers when an application comes from abroad.

Companies and legal professions: articles of association, foreign trade register extracts, powers of attorney, contracts, deeds of sale, accounting documents, judgments and documents filed in proceedings. Notaries and lawyers are the main requesters.

The same document may fall under two regimes depending on its use. A contract read internally does not require a sworn translation; the same contract filed in litigation does.

Key point — it is the use of the document that triggers the obligation, not the type of document.

When is a sworn translation not necessary?

Three situations remove the need for a sworn translation. Most pages on the subject do not mention them.

The multilingual civil status extract. Several international conventions provide for civil status forms written simultaneously in several languages. A multilingual extract of a birth, marriage or death certificate issued by a signatory country is accepted without translation in the other signatory countries. Before ordering a sworn translation, ask the town hall or consulate of the country of origin whether it issues this format.

European standard forms. Between EU Member States, Regulation (EU) 2016/1191, applicable since 16 February 2019, abolished the apostille requirement for a series of public documents — birth, death, marriage, registered partnership, residence, absence of a criminal record — and created multilingual standard forms to be attached to the original document. These forms often remove the need for any translation.

Internal use. A contract, report or correspondence intended to be read by a team does not need to be translated by a sworn translator. Certification does not improve linguistic quality: it adds a legal responsibility that serves no purpose in this context.

Key point — always ask whether a multilingual extract exists before ordering a translation: it often makes the expense unnecessary.

We regularly reply to a quote request by explaining that a translation is not needed. The most frequent case is multilingual documents, particularly European ones: these forms were created precisely to avoid translation within the Union, and many applicants do not know they can obtain one.

The other classic case concerns bank statements produced as proof of income, usually for a loan or rental application. We receive requests covering twenty pages of statements where the organisation only needs one specific piece of information. Before ordering, ask it exactly which pages need to be translated — the answer often cuts the quote by two thirds.

Sworn translator or certified translator: what is the difference?

In France, “sworn translator” refers to a specific judicial status. “Certified translator” has no legal definition: it is a commercial expression, often borrowed from the English certified translator, where the translator or agency certifies their own work. If a French authority asks for an official translation, it is the word “sworn” that counts.

A translation agency is never sworn: only an individual can be. An agency can, however, call on a registered expert. In that case, ask for the name of the expert who will sign and the court of appeal they are attached to, so that you can check for yourself.

Key point — for a French application, insist on the word “sworn” and check the registration on the court of appeal list.

Apostille and legalisation: what changed in 2025

Since 1 May 2025, the apostille has no longer been issued in France by the public prosecutor’s offices at the courts of appeal but by the notarial profession, through fifteen regional councils and inter-departmental chambers of notaries. Territorial jurisdiction has disappeared: any of these centres handles any request, and the procedure is online.

Since 1 September 2025, these same notarial bodies have also issued legalisations, previously handled by the Ministry for Europe and Foreign Affairs. Most pages on sworn translation still describe the old system.

The apostille does not translate any document: it authenticates a signature. An apostille may relate to the original document, to the sworn translator’s signature, or to both. It is the receiving authority that specifies this.

The order of the formalities is crucial. For a foreign document intended for France: apostille in the country of origin, then sworn translation in France. For a French document intended for use abroad: sworn translation, then apostille of the translator’s signature. Done in the wrong order, the whole process often has to be repeated.

Key point — since May 2025 the apostille has been handled by notaries, and since September 2025 legalisation as well. The courts of appeal no longer issue them.

Should you choose a sworn translator near you?

No. A sworn translator registered with any French court of appeal produces a translation that is admissible throughout the country. A prefecture in Lille accepts a translation made by an expert attached to the Bordeaux court of appeal. No legislation requires you to use an expert from the jurisdiction where you live.

Geographical proximity only matters in two cases: an oral service — a hearing, a wedding at the town hall, a signing at a notary’s office, an interview at a prefecture — or handing over in person an original that you cannot part with.

So search for the language pair first. A sworn translator’s registration covers specific languages, and sometimes only one direction of translation: an expert authorised for Italian into French is not necessarily authorised for French into Italian. This becomes crucial when the document is intended for a foreign authority.

Key point — proximity is not a legal criterion. Search for the language before the city.

For some language pairs, the experts registered in France can be counted on the fingers of one hand: Finnish, Amharic, Latvian. Searching within your own department then makes no sense. Widen your search to the whole of France from the start, or contact our team if necessary — we can help you find someone if you are genuinely struggling.

How much does a sworn translation cost in France?

There is no regulated rate for sworn translations ordered by individuals or companies: each expert sets their fees freely. Only translations carried out at the request of a court follow a scale set by decree, which does not apply to private orders.

The price of a sworn translation varies according to five factors: the language pair, the actual volume of the document, the complexity of the layout — a transcript in table form requires more work than running text with the same number of words —, urgency, and the number of paper copies. Additional copies ordered at the same time as the first cost little; ordered later, they mean reopening the file.

On top of the translation price come ancillary costs: registered post, apostille or legalisation, each of which incurs a separate fee charged by the centre that issues it.

Be wary of very low headline prices. Always check what the stated amount includes: the paper copy, postage, reproduction of the layout. A complete quote is often cheaper than a headline price with three extra lines added.

The Directory of Sworn Translators of France quotes an all-inclusive price per document. Quotes within 60 minutes for individuals and 30 minutes for professionals, during our opening hours — Monday to Friday, 8.30 am–12 pm and 2 pm–5 pm. A dedicated address allows urgent requests to be handled outside these hours.

Key point — always ask what the price includes. An all-inclusive price per document is clearer than a headline price with supplements.

How to prepare a sworn translation file

The processing time for a sworn translation depends less on the number of pages than on the quality of what you send.

• Send a complete, legible PDF: front and back, stamps, apostilles, handwritten notes, marginal notes, and apparently blank pages when they are part of the document.
• State the source language, the target language, the recipient country and body, the deadline, whether you need a paper copy and how many copies.
• Specify the exact spelling of names as it appears on your passport or on a French document you already have: a spelling discrepancy is a classic reason for rejection.
• Never retouch a document before sending it. Cropping, corrections or removing a stamp create a discrepancy between the original and the translation.

Key point — a complete, legible scan plus the name of the receiving body are enough to obtain a firm quote first time.

In practice, what most often makes us come back to clients is the quality of the image. We receive photos where the document is lying on a patterned tablecloth, with a glass in the frame and a shadow across the page. A scan remains ideal; failing that, photograph the document flat on a plain, neutral background, in daylight, with no shadow.

If you do not have a scanner, your phone has one built in: the Notes app on iPhone, Google Drive on Android. Both automatically correct perspective, crop and adjust contrast, and produce a usable PDF first time.

If no sworn translator is available near you

Finding no results in your city does not block the process, since the translation is admissible whichever court of appeal the expert is attached to. For an uncommon language, a specialised need or a tight deadline, a nationwide search is almost always the right answer.

The Directory of Sworn Translators of France lets you filter your search by language, specialisation, city, department, region and court of appeal, based on the lists in force. When the search is unsuccessful, submitting an express request directs it to an available expert.

Frequently asked questions

Must the source document be attached to the sworn translation?

At the end of the translation, the sworn translator identifies the document they worked from, and both documents bear the same registration number. Check with the recipient whether the translation must be attached to the original or whether a copy is sufficient.

Does a sworn translation have a period of validity?

No. A sworn translation has no validity period of its own. It is the source document that does: many French authorities require an extract less than three or six months old. Obtain an up-to-date document first, then have it translated.

Can I translate a document myself and have it certified afterwards?

No. The sworn translator takes on legal responsibility and cannot certify a text they have not produced or fully revised.

How can I check that a translator is really sworn?

Consult the list of court-appointed experts of the court of appeal they state, for the current year, in branch H — Interpreting and Translation. The title of expert attached to a court of appeal is protected: claiming it without being registered constitutes misuse of a title.

Is a French sworn translation valid abroad?

Not automatically. Its validity depends on the recipient country. The sworn translator’s signature generally has to be apostilled, a formality issued by notaries since 1 May 2025. Some countries only accept translations made by a sworn translator in their own territory.
