Which Documents Require a Certified Translation?

09 August 2026

Not every document you have requires a certified translation — but not knowing which ones do can lead to needless expense or, conversely, a rejected document. The general rule is simple: if a document will be submitted to an official institution, it most likely needs a certified translation. Here are the most common cases.

Personal Status Documents

Documents like birth certificates, marriage certificates, divorce decrees, and civil registry extracts almost always require a certified translation if they'll be used in a procedure abroad (marriage, residence, citizenship application). Since these documents prove your personal status, their official validity is critical.

Educational Documents

Educational documents like diplomas, transcripts, and enrolment certificates usually require a certified translation for foreign university applications or equivalence procedures. Especially in diploma equivalence processes, the translation being official and accurate matters greatly — even a small error can delay the process.

Legal and Commercial Documents

Legal/commercial documents like contracts, powers of attorney, court decisions, and company documents require a certified translation if they'll be used in an official process. Since the accuracy of the translation carries legal consequences in these documents, the responsibility of an authorised translator is essential.

When a Regular Translation Is Enough

Not everything has to be certified. For understanding an article, translating a website, a personal letter, or informational texts, a regular translation is enough. A certified translation only comes into play when official validity is required — getting a certified translation unnecessarily means spending for nothing.

If you're not sure whether your document needs a certified or a regular translation, just tell us the document and where you'll submit it — we'll tell you clearly which is right. That way you get exactly the translation needed, no more, no less.
