Submitting a naturalisation file in Brussels requires gathering sworn translations that comply with the requirements of the Public Prosecutor and the Immigration Office. In a city as multicultural as Brussels, the Moroccan, Turkish, Congolese and Eastern European communities represent tens of thousands of potential applicants every year. This guide explains exactly which documents to translate and how to proceed.
Belgian naturalisation in Brussels: legal framework and competent authorities
Since the reform of the Belgian Nationality Code (Act of 13 June 1991), substantially amended in 2013, the naturalisation procedure passes through the Chamber of Representatives for exceptional applications, and through the Public Prosecutor for acquisition by declaration. The Immigration Office (OE) and the FPS Justice each play a key role in handling the file.
The role of the Brussels Public Prosecutor
In Brussels, the Public Prosecutor of the Brussels district handles nationality files. It verifies in particular the authenticity of foreign documents and their compliance with the sworn translations provided. Any translation not produced by a translator recognised by a Belgian Court of Appeal is automatically rejected, resulting in the file being returned and months of additional delay.
Brussels's multicultural context
Brussels concentrates the country's largest diasporas: long-established Moroccan and Turkish communities, a significant Congolese community, as well as Polish, Romanian and Bulgarian nationals who arrived after EU enlargement. Each of these communities faces documents written in different languages and scripts, requiring specialised translators - Arabic, Turkish, Lingala, Polish, Romanian, Bulgarian.

FAQ
Frequently asked questions
Does the Brussels Public Prosecutor accept translations carried out outside Belgium?
No. For a naturalisation file submitted in Belgium, translations must be carried out by a sworn translator recognised by a Belgian Court of Appeal and registered in the FPS Justice database. A translation produced by a French or Dutch translator, even if certified, will not be accepted by the Brussels Prosecutor.
Do I need to have my foreign documents apostilled before having them translated?
Not systematically. The apostille or legalisation depends on the document's country of origin and the specific requirements of the Prosecutor. Some countries have bilateral agreements with Belgium that waive the apostille requirement. Check with the Immigration Office or the Brussels Prosecutor before starting the process.
How long does the full naturalisation procedure take in Brussels?
If the file is complete and compliant from the outset, the procedure generally takes between 12 and 18 months. An incomplete file or non-compliant translations can result in delays of 3 to 12 additional months. It is therefore essential to ensure translation quality from the start.
My criminal record is in Arabic - can it be translated urgently?
Yes. TranslateBE has Arabic-French sworn translators available for a 24h turnaround. The Moroccan criminal record (Bulletin No. 3) and the Algerian equivalent are among the documents we process most frequently for Brussels naturalisation files.
