Belgium has hundreds of translation agencies, from multinational language service providers to freelance translators operating as agencies. Choosing the right one for your specific needs - legal, medical, administrative, or commercial - requires a clear set of criteria. Here is a practical checklist of seven factors that matter most.
1. Accreditation and sworn translator registration
For any document intended for official use - immigration procedures, courts, notaries, public administrations - only sworn translations carry legal weight in Belgium. Verify that the agency works exclusively with translators registered on the SPF Justice list of sworn translators and interpreters. This registration is publicly searchable and non-negotiable. An agency that cannot confirm this registration should not be trusted with official documents.
2. Specialisation by domain
A generalist translator competent in literary translation is not qualified to translate a patent, a medical device instruction manual, or a merger agreement. Ask the agency about its specialisations. Leading agencies organise their translators by domain - legal, medical, technical, financial, marketing - and assign documents to translators with verifiable expertise in the relevant field.
3. Language coverage
Belgium's multicultural reality means demand spans dozens of languages. Verify that the agency covers the specific language pairs you need, including less common languages such as Arabic dialects, Lingala, Tigrinya, Dari, or Pashto if relevant. Ask whether rare language pairs are handled by qualified sworn translators or subcontracted to unverified freelancers.

4. Transparent pricing and no hidden costs
Reliable agencies provide a fixed quote before work begins, not an estimate that balloons at invoicing. The quote should specify the per-page or per-word rate, any minimum charge, express surcharges, and what is included (sworn certification, digital delivery, certified hard copy if needed). Be wary of agencies that quote per word for sworn translations - Belgian practice prices sworn translations per page.
5. Quality assurance process
Professional agencies apply a translation-revision-proofreading workflow (TEP process) for important documents. Ask whether the translation is reviewed by a second qualified linguist before delivery. For sworn translations, the sworn translator assumes personal legal responsibility for accuracy - but a revision step nonetheless reduces errors. ISO 17100 certification is the international quality standard for translation services; its presence is a positive indicator though not universal among excellent agencies.
6. GDPR compliance and data security
You are entrusting an agency with sensitive personal documents: passports, medical records, financial statements. Verify that the agency processes data on EU servers, has a documented data retention and deletion policy, and operates under a GDPR-compliant framework. TranslateBE stores all documents on EU-based servers (Frankfurt) and deletes them after delivery. Never use an agency that stores data on US cloud servers without EU Standard Contractual Clauses.
7. Responsiveness and client communication
The speed of quote and delivery is critical for urgent administrative needs. A reliable agency provides a quote within one hour and communicates proactively about delivery timelines. Availability seven days a week is particularly valuable for individuals facing administrative deadlines over the weekend. Test an agency's responsiveness before committing a time-sensitive project.
FAQ
Frequently asked questions
Is ISO 17100 certification mandatory for a Belgian translation agency?
No, it is not legally mandatory. However, ISO 17100 certification demonstrates that the agency has implemented a quality management system meeting the international standard for translation services, including translator qualification requirements and a review process. It is a useful indicator of professionalism but not the only one.
Can I use a freelance translator instead of an agency for official Belgian documents?
Yes, if the freelancer is individually registered as a sworn translator with a Belgian Court of Appeal. The legal value is identical. An agency adds value through coordination, quality review, coverage of multiple languages, and reliability - important for companies with ongoing translation needs.
What questions should I ask before placing an order with a new translation agency?
Key questions: Are your translators registered on the SPF Justice sworn translator list? Can you confirm which translator will handle my document and their qualifications? What is your data protection and document deletion policy? Is the quote fixed or can it change after delivery? What is your complaints and correction procedure?
