ChatGPT translates in seconds, DeepL rivals professionals on everyday texts, and Google Translate is free and available everywhere. Yet for your official documents in Belgium, these tools have fundamental limitations that neither algorithms nor speed can overcome.
What AI Tools Do Very Well
It would be dishonest to deny the spectacular progress of machine translation in recent years. Large language models like GPT-4, combined with specialised engines such as DeepL, produce fluent, coherent, and often very accurate translations across a wide range of content.
For informal emails, marketing copy, blog articles, document summaries, or video subtitles, AI is a fast and cost-effective solution. Many translation agencies already use machine translation as a first pass, followed by human post-editing - the MTPE (Machine Translation Post-Editing) model.
- Speed: a page translated in seconds versus 30-60 minutes for a human translator
- Cost: near zero for non-critical uses
- Availability: 24/7, no appointment needed
- Terminological consistency: the best tools maintain consistent terminology across long texts
The Structural Limits of AI for Official Documents
Here is what AI tools cannot do, regardless of their linguistic performance:
AI Cannot Take an Oath
In Belgium, a sworn translation is produced by a translator who has taken an oath before a Court of Appeal or the National Commission of Sworn Translators-Interpreters (CNTI). This oath engages their personal and professional responsibility for the accuracy of the translation. No algorithm can take an oath, and no Belgian authority will accept an AI-produced translation as an official translation, even if it is linguistically flawless.
AI Cannot Affix an Official Stamp
Official Belgian documents - civil status records, judgments, diplomas, company articles - must be accompanied by a translation bearing the stamp and handwritten signature of the sworn translator. Without these physical elements, the document will be rejected by municipalities, notaries, courts, and the FPS Justice.
AI Makes Errors on Legal and Cultural Nuances
Legal, medical, and administrative texts are laden with terms whose translation requires deep sector-specific expertise. An error in translating a term from Moroccan family law, a testamentary provision, or a medical diagnosis can have serious consequences. AI sometimes hallucinates non-existent terms or translates legal idiomatic expressions word-for-word, losing their precise technical meaning.
Good to know
A 2023 study by the European Commission Joint Research Centre found that even the best machine translation tools produce significant errors in 10-20% of segments in complex legal texts. For a birth certificate or a divorce judgment, a single error can invalidate the entire procedure.
An Honest Comparison: AI vs. Sworn Human Translator
| Criterion | AI (ChatGPT, DeepL…) | Sworn Human Translator |
|---|---|---|
| Official legal value | None | Full probative value |
| Official stamp and signature | Impossible | Included |
| Speed | Instantaneous | 24 hours to 5 days depending on volume |
| Reliability for legal texts | Variable, errors possible | Sector expertise |
| Accountability | None | Personal and professional liability |
| Rare languages | Uneven quality | Specialists available |

When AI Is Acceptable and When It Is Not
The rule is simple: if the document is to be presented to an official Belgian or foreign authority, AI alone is never sufficient. If the document is for internal, informational, or personal use, AI can be a useful starting point.
AI Can Be Sufficient for
- Understanding the general content of a document before having it officially translated
- Translating internal professional emails
- Drafting a non-official commercial document
- Subtitling videos or translating social media content
AI Is Never Sufficient for
- Civil status records (birth, marriage, death) for a Belgian authority
- Diplomas and transcripts for NARIC equivalency or university enrolment
- Divorce judgments, custody orders, or court rulings
- Company articles of association for registration with the BCE
- Medical records for hospital admission
- Estate documents presented to a notary
- Any document required for a visa or residence permit application
The Hybrid Model: AI + Human Sworn Review
Some agencies offer a hybrid model where AI generates a first draft and a sworn translator then reviews and certifies the translation. This model can reduce costs for large volumes, provided the human review is truly thorough and the final translation is signed and stamped by a certified sworn translator.
At TranslateBE, we use translation assistance tools (CAT tools) to improve consistency and speed, but every sworn translation is fully verified, signed, and stamped by an approved Belgian sworn translator.
FAQ
Frequently asked questions
Is a DeepL translation accepted by Belgian municipalities?
No. Belgian municipalities, like all public administrations, require a sworn translation bearing the stamp and signature of a translator certified by a Belgian Court of Appeal or the CNTI. A DeepL translation, however linguistically accurate, carries no official value and will systematically be refused for civil status records, identity documents, or proof of family status.
Can ChatGPT produce reliable translations of medical documents?
ChatGPT can produce an understandable translation of medical documents for personal informational use. However, for medical and legal reasons, a medical translation destined for a hospital, insurance company, or physician must be produced by a translator specialising in medical terminology. Errors in dosages, diagnoses, or surgical protocols can have serious consequences for patient health.
Is it legal to use AI for a translation that is then certified?
A sworn translator may use assistance tools (including AI) as an aid to translation, provided they fully review the output, take personal responsibility for the final text, and endorse it with their stamp and signature. What is problematic is presenting a raw AI translation as certified without serious review. The sworn translator bears personal and professional responsibility for the accuracy of the text they certify.
Is AI better than a human for certain language pairs?
For very common language pairs (English-French, French-Dutch, Spanish-English), the best AI tools reach a very satisfactory level for everyday texts. But for languages with less training data - Amharic, Somali, Tigrinya, Pashto, Berber - AI quality drops significantly. Human translators specialising in these languages remain indispensable, even for non-official texts.
