Brussels is both officially bilingual and deeply multilingual, making professional certified translation essential for businesses, institutions and individuals across the city. Understanding when a certified (rather than sworn) translation is appropriate can save you time and money. This guide covers certified translators in Brussels: ISO 17100 standards, language coverage and when sworn certification is not required.

Brussels and the bilingual translation challenge
The Brussels Capital Region is officially bilingual French-Dutch, but English functions as a de facto third working language across European institutions, international organisations and the multinational business community. This means that certified translation in Brussels often involves not just French and Dutch, but also English, German, Spanish and a wide range of other languages.
The demand for certified translation (as opposed to sworn translation) is driven largely by Brussels' concentration of European institutions, lobby groups, law firms and multinationals. These organisations need high-quality, professionally certified translations of contracts, policies, communications and technical documents - but they do not typically submit documents to Belgian administrative authorities, so a sworn translation is not required.
When does a certified (non-sworn) translation suffice in Brussels?
- European institutions and agencies: internal translation, reports, publications and communication documents
- Law firms: translations of contracts, legal opinions and correspondence for client files not submitted to Belgian courts
- Multinational companies: HR documents, internal policies, commercial contracts and annual reports
- NGOs and international organisations: funding applications, project reports and stakeholder communications
- Marketing and communication agencies: campaign materials, websites and press releases in multiple languages
- Technical departments: product manuals, technical specifications and quality documentation

ISO 17100 and quality in Brussels
ISO 17100 is the international standard defining the requirements for professional translation services. Agencies working to this standard guarantee that translations undergo a structured process: translation by a qualified professional, independent revision, and a final quality check. For businesses and institutions where accuracy and consistency matter - legal texts, technical documents, regulatory filings - ISO 17100 compliance provides meaningful assurance.
Brussels' demanding institutional and corporate clients increasingly specify ISO 17100 compliance in their translation requirements. TranslateBE applies ISO 17100-aligned quality controls to all professional certified translations, ensuring a consistent standard regardless of language pair or subject area.
When sworn translation is required in Brussels
Even in Brussels' sophisticated professional environment, sworn translation remains mandatory for specific situations: civil status documents submitted to Brussels municipalities, DVZ/Office des Étrangers immigration files, criminal records for professional licensing, documents submitted to Belgian courts and diplomas for NARIC Belgium. If your document is destined for a Belgian authority, check our guide on sworn translation to confirm the requirement before ordering.
FAQ
Frequently asked questions
Does the European Commission accept certified translations from external agencies?
The European Commission and other EU institutions have their own internal translation services (DGT), but they also commission external translations from professional agencies. External certified translations are accepted for contractual, communication and administrative purposes, provided they meet professional quality standards.
Can a Brussels law firm use a certified (non-sworn) translation for a client contract?
Yes, for contracts between private parties that are not submitted to a Belgian court or authority. A professional certified translation produced by a qualified translator is appropriate for client file documentation, legal opinions and correspondence. Only documents submitted to Belgian courts or authorities require a sworn translation.
