DeepL or a sworn translator: what is the difference?

These are not two tiers of the same product. DeepL provides machine translation; a sworn translator provides a checked translation they can certify within their registered languages.

DeepL optimises a sentence

Link to this section

DeepL can be efficient for quickly reading a letter or preparing a discussion. Its output is calculated from the supplied text and does not ask the authority whether the correct document version, target language or formality was chosen.

A sworn translator puts a person behind the work

Link to this section

The National Register ties the assignment to a person, VTI number and specific languages. That person checks the document, applies the conformity wording and signs it. This verifiable chain, not merely polished wording, distinguishes the sworn version.

Compare the right cost

Machine translation looks free if checking time, file errors and possible rework after refusal are ignored. For private use, that risk may be acceptable. For an official record, compare the cost of a usable first-time version instead.

The simple choice

Link to this section

Need to understand it today: the tool can help. Need to submit it officially: check the recipient's requirement and, if a sworn translation is requested, choose a person registered for the language pair.

Documents to prepare

  • Text, seals and annotations
  • Exact spelling of identities
  • Final use of the document

Steps to follow

  1. Define the use

    Separate private reading from official submission.

  2. Check the requirements

    Ask about language, format and any legalisation.

  3. Compare on responsibility

    For a sworn version, verify the person and languages in the Register.

Frequently asked questions

+Is DeepL less accurate than a sworn translator?
Accuracy varies by text. The certain difference is legal and professional: DeepL is not a registered person who checks, certifies and signs.
+Can I send DeepL output to the translator?
Yes as working material if you also send the complete source. The translator may start again and must check the whole result.
+Is DeepL enough for a municipality?
Only if that municipality accepts the original language or a simple translation for the specific procedure. Ask before filing.
+Can DeepL translate seals and illegible passages?
It may suggest text, but only the professional decides how to faithfully report a seal, note or genuinely illegible passage in the final version.
