Applying for Belgian nationality is one of the most significant administrative procedures a foreign national can undertake in Belgium. Assembling the correct documentation - with the right translations - is critical to avoiding delays or rejection. This guide covers the full list of documents typically required and their translation requirements.
Overview of the Belgian nationality procedure
Belgian nationality can be acquired through several routes, the most common being naturalisation (procedure before Parliament, now very restricted), declaration of nationality (the main route for most residents meeting specific conditions), and attribution (by birth or adoption). For the declaration of nationality - the route available to most long-term residents - the file is submitted to the commune and then reviewed by the public prosecutor's office and the DVZ.
The procedure requires proof of legal residence, social integration, economic participation, and linguistic knowledge. Each of these elements involves specific documents, many of which must be accompanied by sworn translations if originally in a foreign language.
Documents requiring sworn translation
The following documents, if not originally in French, Dutch, or German, must be accompanied by a sworn translation:
- Birth certificate: the full civil registry extract from your country of origin, including parents' names and date and place of birth
- Marriage certificate or proof of civil status: if married, widowed, or divorced
- Foreign diplomas: if claimed as evidence of social integration or professional activity
- Criminal record certificate from country of origin: typically required from each country where you resided for more than six months; must be recent (usually less than three months old at time of submission)
- Proof of integration activities in a foreign language: participation certificates, civic courses completed abroad
- Foreign court judgments: divorce decrees, adoption orders, custody arrangements

DVZ/Office des Étrangers specific requirements
The DVZ/Office des Étrangers reviews the file after the commune's initial assessment. Their translation requirements are strict: only sworn translations by a translator registered on the official SPF Justice list are accepted. Standard certified translations or translations produced by unofficial services (including online machine translation with a declaration of accuracy) are rejected without exception.
TranslateBE's sworn translations are systematically accepted by Belgian communes, the DVZ/OE, and the public prosecutor's office for nationality procedures. Our translators are familiar with the specific formatting requirements and terminology of Belgian nationality files.
Practical tips for your nationality file
Request your translations early - the criminal record certificates in particular have a limited validity period (typically three months), so timing matters. Keep the original and the sworn translation together in your file. If your commune asks for a "legalised" original, confirm whether they mean an apostille or simply a certified copy before incurring apostille costs.
FAQ
Frequently asked questions
Do all documents in my nationality file need to be translated, even old ones?
Generally yes, if they are in a foreign language. However, some communes are flexible about very old documents (for instance, documents from the 1950s or 1960s where the civil registry office no longer exists). Discuss with your commune's naturalisation officer if you have documents that are particularly difficult to obtain in original or translated form.
Can I use one sworn translation for both the commune and the DVZ/OE?
Yes. A single sworn translation is valid for all Belgian public authorities. You do not need separate translations for the commune and the DVZ/OE. We recommend keeping the digital PDF and requesting a physical certified hard copy only if specifically required by your commune.
My country of origin no longer exists (USSR, Yugoslavia). How do I provide a birth certificate?
This is a known situation in Belgian nationality procedures. Successor state civil registries (Russian, Ukrainian, Serbian, Croatian, Slovenian, etc.) can often issue new certificates for records in their archives. Belgian communes and the DVZ/OE have experience with successor state documents. TranslateBE translates documents from all these archives, including those in Russian, Ukrainian, Serbian, and other languages of the former Soviet and Yugoslav states.
