What makes a sworn translation legally valid in Belgium?

In Belgium, a sworn translation derives its legal value not from how it was delivered (online or in person) but from who produced it. A sworn translator must be registered on the national register maintained by the SPF Justice (Service Public Fédéral Justice), which is publicly accessible online. This registration confirms that the translator has sworn an oath before a Belgian Court of Appeal and is authorised to certify translations for official Belgian procedures.

A certified PDF delivered electronically by a registered sworn translator carries exactly the same legal weight as a paper document handed over at a physical agency. Belgian law does not require sworn translations to be produced in person. What matters is the translator's registered status and the presence of their certified signature on the translation.

Which authorities accept online sworn translations in Belgium?

• DVZ / Office des Étrangers: accepts certified PDFs for residence permit, family reunification and naturalisation files
• Belgian municipalities: accept online sworn translations for civil registry, marriage and residence procedures
• Notaries: accept certified PDFs for inheritance, property and contract procedures in most cases
• NARIC Belgium: accepts sworn translations of foreign diplomas submitted electronically
• Belgian courts: sworn translations submitted as evidence must generally be provided in original paper form with the translator's wet signature
• Embassies: requirements vary; some accept certified PDFs, others require hard copies

When is a physical original still required?

Despite the widespread acceptance of electronic certified translations, there are situations where a physical document is still required:

• Court proceedings: Belgian courts typically require the sworn translation to be submitted in paper form, with a wet signature and official stamp from the translator
• Apostille and legalisation procedures: when a Belgian document must be used abroad with an apostille, the underlying translation may need to be in paper form
• Certain embassies and consulates: some foreign diplomatic representations require physical documents rather than certified PDFs
• Notarial acts in some jurisdictions: certain notarial procedures in specific countries require the translation to be presented in original paper form

TranslateBE always advises clients on the format required for their specific procedure. When a physical document is needed, we send the certified paper translation by tracked post.

E-signature and digital certification: what is accepted?

Belgian sworn translators typically certify their online translations with a combination of a scanned wet signature and official stamp applied to the PDF, together with a signed cover letter confirming the translation's accuracy. Some translators also use qualified electronic signatures (eIDAS-compliant). Both formats are accepted by Belgian administrative authorities. For court proceedings, most Belgian courts still require a physical wet signature. We will always advise you on which format is appropriate for your authority.
