What France means by “official translation”
An official translation, also known as a sworn translation in France (traduction assermentée), is a translation completed by a professional translator who has taken an oath before a French Court of Appeal (Cour d'Appel). This translator is also listed on that court's official register of judicial experts. Once registered, their translations carry a stamp, a signature, and a certification statement that French administrations recognise as legally valid.
This is different from certified translations in the UK or US, where certification means that the translation includes a signed statement of accuracy from the professional translator or translation agency.
In France, only sworn translators, approved by a French Court of Appeal (Cour d'Appel), can produce a traduction assermentée. It is also the only type most French institutions will accept for official purposes.
You can search for a registered sworn translator through the official court expert lists, or via the national list maintained by the Cour de Cassation. Each Court of Appeal publishes its own regional list, allowing you to search for translators by language and jurisdiction.
You don't need to be in France to work with a sworn translator. Professional translation agencies like Translayte work with a network of sworn translators who can translate your documents for use in France and deliver them to you digitally.
How many documents will you need to translate before you leave
Use this checklist to work out what applies to your situation. For document-specific translation guidance, see our immigration document translation guide.
For long-stay visa application: birth certificate, passport, criminal record certificate (police clearance), and marriage certificate if applicable. Criminal record certificates and civil status documents are almost always required to be sworn translations. Supporting financial documents (payslips, bank statements) have a lower sworn rate, and you should confirm requirements with your consulate.
For opening a French bank account or registering with CPAM, a birth certificate is the document most commonly requested. In our French orders, 75% of birth certificate translations are sworn when submitted to French authorities.
For enrolling children in a French school: birth certificates and vaccination records.
For getting a carte de séjour (residence permit), this category has the highest number of documents usually translated. The exact documents depend on your permit category, but typically include civil status documents plus proof of the underlying basis for your stay (employment, family, study).
For naturalisation: 92.7% of naturalisation-related translation orders we process for France are sworn translations.

How much does document translation cost for a France relocation?
The answer depends almost entirely on what you are applying for. Here is what we see in practice, based on France's sworn translation orders that we’ve processed over the past year:
Purpose | Avg number of documents | % age of sworn translations | Avg total cost | Avg cost per document |
Naturalisation / French nationality | 2.3 | 92.7% | £84 / €96 | £37 / €42 |
PACS registration | 1.7 | 78.1% | £65 / €74 | £38 / €43 |
Marriage at a mairie | 1.8 | 90.6% | £78 / €89 | £43 / €49 |
Titre de séjour (residence permit) | 5.6 | 92.9% | £67 / €76 | £38 / €43 |
Visa application | 2.8 | 41.2% | £78 / €89 | £28 / €32 |
University enrolment | 13.8 | 35.1% | £110 / €125 | £8 / €9 |
Divorce proceedings | 3.7 | 84.0% | £136 / €155 | £37 / €42 |
Court / legal proceedings | 5.5 | 66.7% | £171 / €195 | £31 / €35 |
Three things to note from this;
Titre de séjour applications involve more documents than most other use cases: An average of 5.6 sworn translations per order. This reflects that a carte de séjour application requires proof of civil status (birth certificate), proof of family situation (marriage certificate if applicable), and proof of the basis for your stay, all of which need sworn translation.
University enrolment averages 13.8 documents, by far the highest of any category. This is driven by full academic transcript sets, where every individual grade document requires separate translation alongside the degree certificate itself.
Visa applications have the lowest sworn rate at 41%, because a significant share of visa-related orders involve translating supporting documents like payslips and bank statements, which French consulates sometimes accept standard certified translation rather than sworn translation.
A single sworn translation for France costs £39 / €44 on average. If you are preparing a titre de séjour application, budget for five to six sworn translations, around £190 / €217 in total before accounting for apostille fees.

Do you also need an apostille?
Yes. France is a member of the Hague Apostille Convention. This means if you’re coming from a country that’s also a member of the Hague Apostille Convention, you only need an apostille to legalise your documents for use in France.
An apostille is a form of authentication that confirms a foreign public document is genuine, so it can be recognised in another country.
If your birth certificate, marriage certificate, or police record was issued in a country that's party to the 1961 Hague Convention (which includes the UK, the US, Canada, Australia, and most Commonwealth countries), you'll need an apostille on the original document before it's translated.
If your document was issued in a country that is not part of the Hague Convention, you'll need diplomatic or consular legalisation instead, which is a separate and generally slower process.
The apostille has to be obtained in the country that issued the document, not in France. Over a quarter (25%) of France visa and residence permit translation orders we process are placed urgently.
In most cases, this is not because applicants left the translation late; it is because the apostille took longer than expected and compressed the remaining timeline. Apostille processing times vary significantly by country: UK applicants use HM Apostille Office (typically 3-4 weeks for the standard service); US applicants apply to their state's authentication office. Allow more time for the apostille step.
Our guide on France apostille requirements covers this in more detail, including which authority issues apostilles in different countries.
Can you get the translation done before arriving in France?
Yes, you can get your sworn translations before arriving in France. Most applicants work with professional translation agencies or independent sworn translators remotely to translate documents and receive them digitally, valid for official use in France.
You don't need to hand over a physical original in person, and you don't need to be resident in France to commission the translation.
The practical order to follow is: get the apostille in your home country first (if your country is a Hague Convention member) or undergo consular legalisation, then order sworn translations. Doing it in this order means the finished translation covers the apostilled or legalised document.
The 'fresh document' rule
Many French institutions, including préfectures and CPAM offices, will only accept certain civil status documents (birth certificates in particular) if they were issued within the last 3 to 6 months. Requirements vary by institution and by document type, so check with the specific authority you're dealing with.
This rule applies to the original document, not the translation. A sworn translation itself doesn't expire, but if the underlying document is considered too old by the receiving authority, you'll need a fresh copy of the original translated again. Order a new copy of your birth certificate close to your departure date, rather than using one issued years earlier, to avoid this problem.
