Certified Translation: When Do You Need One?

You have been asked to provide a “certified translation” of your birth certificate, diploma or marriage certificate. Perhaps by an immigration office, a university admissions department or a foreign court. But what exactly qualifies as a certified translation — and how do requirements differ from one country to the next?

This guide explains when you need a certified translation, how the process works at Ecrivus International, what it costs, and how certification standards vary across jurisdictions.

When do you need a certified translation?

A certified translation is required whenever an official authority needs assurance that a translated document is accurate and complete. In practice, you will encounter this requirement in the following situations:

Immigration and visa applications

Virtually every immigration authority worldwide requires certified translations of supporting documents. The Dutch IND, German BAMF, UK Visas and Immigration (UKVI) and US Citizenship and Immigration Services (USCIS) all require certified translations of birth certificates, police clearances, financial statements and sponsorship declarations. If you are applying for a work permit, family reunification visa or permanent residence, expect every foreign-language document in your file to need certification.

Academic credential recognition

Universities and credential evaluation bodies require certified translations of diplomas, transcripts, course descriptions and academic references. In Europe, this includes NUFFIC and IDW (Netherlands), anabin and uni-assist (Germany), NARIC (UK and other EU countries) and ENIC-NARIC (France). In the US, World Education Services (WES) and Educational Credential Evaluators (ECE) both require certified translations of all non-English academic records.

Court proceedings and litigation

Courts require certified translations of contracts, judgements, witness statements, powers of attorney, expert reports and other evidentiary documents. In most jurisdictions, an uncertified translation will simply be rejected by the court clerk. This applies to civil, criminal and administrative proceedings alike. If you are involved in international litigation, arbitration or mediation, certified translations of the entire case file may be required.

Civil registry submissions

Birth, marriage, divorce and death certificates submitted to a municipality, embassy or consulate must be certified. This is particularly common when registering a foreign marriage, applying for a name change, or obtaining a new passport based on foreign civil status documents.

Business and corporate filings

Articles of association, shareholder resolutions, annual reports, trade register extracts, powers of attorney and board resolutions often need certification when used across borders. Companies expanding internationally or participating in foreign tenders frequently need certified translations of their corporate documents.

Healthcare and regulatory filings

Medical reports, clinical trial documentation, pharmaceutical dossiers, patient information leaflets and regulatory submissions to foreign health authorities (such as the EMA, FDA or MHRA) often require certified translations to ensure accuracy in safety-critical contexts.

Rule of thumb: if a government body, court or regulated institution is the recipient, assume a certified translation is needed unless told otherwise.

Certified vs standard translation: what is the difference?

Not every translation needs to be certified. Understanding the difference helps you avoid unnecessary costs — and ensures you get the right type of translation when it matters.

When a standard translation is sufficient: internal business communication, marketing content, website localisation, product descriptions, technical manuals, employee handbooks and any context where the translation does not need to be presented to a government body or court. For such content, machine translation post-editing (MTPE) can be a cost-effective alternative.

When you need a certified translation: any document destined for an official authority, court, notary, university admissions office, immigration service or regulatory body.

How does the process work?

At Ecrivus International, we handle certified translations for over 225 language combinations. Here is how the process works from start to finish:

Step 1: Submit your document

Upload a clear scan (300 dpi minimum) or a sharp photo of your document through our quote request form, by email, or via our online contact form. You do not need to send the original.

Step 2: Assessment and quote

Our project manager reviews the document, confirms the target language and certification requirements for your specific authority, and checks whether an apostille or notarisation is needed. You receive a binding quote within one business day.

Step 3: Translation by an accredited translator

Your document is translated by a sworn or accredited translator who holds the appropriate credentials for your target country (see the section below on certification standards). The translator attaches a signed declaration, personal stamp and — where applicable — a court registration number.

Step 4: Quality review

A second linguist reviews the translation for accuracy, completeness and formatting. For certified translations, precision matters: a single misspelling in a name or date can lead to rejection.

Step 5: Delivery

You receive the certified translation as a secure PDF with a qualified electronic signature. If you need a hard copy with an original stamp and wet-ink signature, we ship it by registered post to any address worldwide. Most certified translations are delivered within 2 to 5 business days, depending on the language pair and document length.

Costs and turnaround

Pricing depends on the language pair, document length and urgency. Below are our indicative rates:

What affects the price? The main cost drivers are: the language pair (rare languages cost more due to limited availability of sworn translators), document complexity (legal or technical terminology increases the per-page rate), urgency (rush surcharges typically add 50–70% to the standard rate), and whether physical delivery or apostille handling is required.

What makes a translation officially certified?

The term “certified translation” means different things in different countries. Understanding the distinction is important, because submitting the wrong type can result in rejection.

The Netherlands — Rbtv register

In the Netherlands, a beëdigd vertaler (sworn translator) must be registered in the Register beëdigde tolken en vertalers (Rbtv), maintained by the Bureau Wbtv. Only translations produced by Rbtv-registered translators are accepted by Dutch courts, the IND (immigration service) and municipalities. The translator affixes a personal stamp, signature and a sworn declaration.

Germany — Landgericht authorisation

In Germany, a beeidigte/r Übersetzer/in (sworn translator) is authorised by the Oberlandesgericht (Higher Regional Court) or a state-level authority. The translator’s stamp includes a court registration number. German authorities such as the BAMF, Standesamt and Ausländerbehörde require this specific type of certification. Requirements can vary between Bundesländer — a translator authorised by the OLG Düsseldorf is generally accepted nationwide, but some authorities may have specific preferences.

United Kingdom

The UK does not have a statutory register of sworn translators. Instead, translations are typically certified by the translator (who attests their competence) or by a translation company. For immigration purposes, UKVI accepts translations accompanied by the translator’s credentials, contact details and a signed accuracy statement. Membership of a professional body such as the Chartered Institute of Linguists (CIOL) or the Institute of Translation and Interpreting (ITI) adds credibility.

United States

In the US, USCIS requires a “certified translation” consisting of the translation itself plus a signed Certificate of Accuracy. The certificate must state that the translator is competent in both languages and that the translation is accurate and complete. In some states, a notarised translation — where a notary public witnesses the translator’s signature — may be required for court or real estate matters.

France — expert judiciaire

In France, a traducteur expert judiciaire must be registered with a cour d’appel (Court of Appeal). Only translations by registered experts are accepted by French courts, préfectures and the OFPRA (the French asylum authority). The translator affixes an official stamp bearing their court registration details and signs a sworn declaration.

International use — apostille

For documents destined for use in a country that is party to the Hague Apostille Convention (currently over 120 member states), an apostille authenticates the translator’s signature and stamp for international recognition. The apostille is issued by the competent authority in the country where the certified translation was produced — for example, the Rechtbank in the Netherlands or the Landgericht in Germany. Ecrivus can arrange apostilles through the relevant national authority on your behalf, saving you the complexity of navigating government procedures in a foreign language.

FAQ

How long is a certified translation valid? There is no universal expiry date. However, some authorities impose their own limits: the Dutch IND typically accepts translations up to 6 months old, while some UK universities require translations dated within 3 months. USCIS in the US does not set a specific expiry, but recommends that translations be as recent as possible. Always check with the receiving institution before submitting.

Can I use a certified translation from one country in another? Not always. A translation certified by a Dutch sworn translator (Rbtv) may not be accepted by German authorities, which require a Landgericht-authorised translator. Similarly, a French expert judiciaire certification is not automatically valid in Belgium or the Netherlands. Ecrivus works with translators accredited in multiple jurisdictions, so we ensure your translation meets the exact requirements of the target authority.

Do you accept digital document submissions? Yes. A clear scan or high-resolution photo is sufficient to start the translation. If the receiving authority requires the original source document to accompany the translation, we will let you know upfront.

Is an apostille included in the price? The apostille is a separate government-issued document with its own fees and processing time (typically 5 to 10 business days). We can handle the entire apostille procedure on your behalf for an additional service fee. Mention your apostille requirement when requesting a quote so we can include it in the timeline and pricing.

Can you provide certified translations for rare languages? Yes. Our network covers 225+ languages, including less common languages such as Tigrinya, Pashto, Dari, Somali, Amharic, Urdu, Farsi, Kurdish (Sorani and Kurmanji) and Swahili. For rare language pairs, turnaround may be slightly longer, but we always confirm the timeline before you commit.

What happens if my certified translation is rejected? Rejections are extremely rare when the correct certification type is used. If a rejection does occur due to an error on our part, we correct the translation free of charge. This is why it is important to tell us exactly which authority will receive the document — we then ensure the right type of certification, stamp and format from the start.

Do I need a certified translation if I already have an apostille on my original document? Yes. An apostille on the original document authenticates the document itself — it does not replace the need for a certified translation. If the receiving authority requires a translated version, you will need both the apostilled original and a certified translation. In some cases, the certified translation itself also needs an apostille.

How do I know if my translator is properly accredited? Every certified translation we deliver includes the translator’s full credentials: their name, registration number, the court or authority that authorised them, and their official stamp. You can verify this information with the relevant register — for example, the Rbtv in the Netherlands or the court registry in Germany.
