The 3 official sources mainly help keep the sequence sharp: recent record first, any apostille or legalisation next, then the right filing step.
The starting point is not the translation but the legal basis of the file. Family reunification with a Belgian is not handled like reunification with an EU/EEA citizen. The relationship invoked, the sponsor's situation and the filing date determine which documents are needed and which authority is competent.
In almost every case you need an identity document, an official record proving the family link and, depending on the case, documents relating to residence, resources, housing or insurance of the sponsor. If the records come from abroad, check the required authentication first and then the sworn translation into the language useful for the procedure.
The standard route is a D-visa application lodged abroad with the competent diplomatic or consular post. Some applications filed in Belgium follow a specific procedure that must be checked case by case with the Immigration Office and the competent municipality.
First verify the invoked family category and the filing date of the application.
Collect the civil-status records and the documents relating to the Belgian sponsor's situation.
Obtain any required apostille or legalisation first, then the sworn translation of the relevant documents.
Submit the complete file to the post or authority that is actually competent for your situation.
Before preparing the file, check whether your application falls under the rules in force from 18 August 2025 or under transitional rules.
Start with recent, complete and consistent civil-status records. Additional evidence does not automatically replace an available official record.
Our sworn translators can translate and certify all documents required for your procedures.
