Judicial Proceedings Translation Luxembourg-Belgium

A judgment handed down in Luxembourg needs to take effect in Belgium. A divorce pronounced in Luxembourg City, a commercial decision of the Tribunal d'arrondissement, a child custody order: these are decisions that must sometimes be recognised and enforced across the border. This guide explains the European legal framework, which documents require translation, and the concrete steps for enforcing a Luxembourg decision in Belgium.

The European framework: Brussels I bis Regulation (EU) No 1215/2012

In civil and commercial matters, the recognition and enforcement of judgments between EU member states is governed by Regulation (EU) No 1215/2012, known as "Brussels I bis", applicable since 10 January 2015. It replaces and considerably simplifies the former exequatur procedure: since its entry into force, a civil or commercial judgment handed down in a member state is recognised automatically in all other member states, without needing to be declared enforceable beforehand.

In practice, if you hold a Luxembourg judgment ordering a Belgian debtor to pay a sum, you can request its direct enforcement in Belgium by presenting the judgment together with theArticle 53 certificate issued by the Luxembourg court. This standardised certificate (the form in Annex I of the Regulation) certifies that the judgment is enforceable in the issuing state. It is written in the language of the issuing court, meaning French or German in Luxembourg.

Note: in family law matters (divorce, filiation, parental responsibility, maintenance obligations, successions), other European regulations apply. Brussels II ter Regulation (EU) 2019/1111 governs the recognition of divorce judgments and parental responsibility decisions between member states since 1 August 2022.

Types of Luxembourg judgments that may require translation

Situations where a Luxembourg judgment must be produced in Belgium are more common than one might expect for frontier workers and their families:

• Civil condemnation judgments: a Belgian creditor who has won a case before the Luxembourg Tribunal d'arrondissement wants to seize assets or bank accounts held by the debtor in Belgium. They present the judgment and the Article 53 certificate to the competent Belgian court or directly to a Belgian bailiff.
• Luxembourg divorce judgments: if one of the former spouses lives in Belgium and the divorce was pronounced in Luxembourg, registration of the divorce in the Belgian civil status registers requires presenting a translated judgment and the European divorce certificate.
• Filiation decisions: recognition of paternity, adoption, change of name: decisions pronounced in Luxembourg must be entered in the Belgian civil status registers and require a sworn translation.
• Commercial judgments: between companies with cross-border activities, commercial disputes are frequent. A judgment of the Luxembourg commercial court against a Belgian company will need to be enforced in Belgium by a Belgian bailiff.
• Provisional orders and interim measures: freezing orders, payment injunctions, interim orders: these urgent decisions may also require rapid enforcement in Belgium.

The Luxembourg judicial system: what Belgian practitioners need to know

The Luxembourg judicial system is organised into three main levels. The Tribunal d'arrondissement (there are two: Luxembourg City and Diekirch) is the ordinary court of first instance for civil, commercial, and criminal matters exceeding the jurisdiction of the justices of the peace. The Cour d'appel of Luxembourg is the sole court of appeal for the entire territory. The Luxembourg Cour de cassation is the supreme court of the judicial order.

A point that often confuses Belgian practitioners: in Luxembourg, there is no separation between civil and commercial chambers at the same level as in certain Belgian courts. The Tribunal d'arrondissement handles both types of matter through internal specialised chambers. Luxembourg judgments mention the sitting chamber (for example "Chambre commerciale du Tribunal d'arrondissement de Luxembourg"), which can be confusing for a Belgian reader unfamiliar with the structure.

The language of proceedings in Luxembourg is officially French, German, or Luxembourgish, at the choice of the parties. In practice, civil and commercial judgments are predominantly written in French, which simplifies matters for Belgian parties. However, some judgments, particularly in cases involving German-speaking parties or lawyers, may be rendered in German.

The role of the bailiff: differences between Luxembourg and Belgium

In Belgium, the bailiff (huissier de justice) is the ministerial officer responsible for serving procedural documents and enforcing court decisions by compulsion. In Luxembourg, the role exists as well but with some practical differences.

To enforce a Luxembourg judgment in Belgium, it is a Belgian bailiff who carries out the enforcement acts (seizure, service of process, etc.). They must present the Luxembourg judgment, together with the Article 53 certificate and its translation if required, to the debtor and to seized third parties. A Belgian bailiff cannot act solely on the basis of an untranslated foreign-language document: they must be able to understand and certify the content of the title they are enforcing.

In practice, when a Luxembourg lawyer instructs a Belgian colleague for the enforcement of a judgment, the translation of the judgment and the Article 53 certificate is included in the documents transmitted as a matter of course. It is a step that neither the Belgian lawyer nor the Belgian bailiff can skip.

Timelines and translation requirements for Belgian courts

Belgian courts do not have a single statutory deadline for requiring translations of foreign documents, but the Belgian Judicial Code provides that documents produced in proceedings must be written in the language of the proceedings or accompanied by a translation into that language. In Wallonia and Brussels (for French-language proceedings), Luxembourg documents in German must be translated into French. In Flanders, they must be translated into Dutch.

The translation must be sworn when it is produced as evidence or as an enforceable title. A standard translation is not sufficient for judicial documents before Belgian courts. The sworn translator affixes their signature and stamp to each page of the translation, attesting to its faithfulness to the original.

In terms of turnaround time, allow 48 hours on an express basis and 3 to 5 business days as standard for the translation of a judgment of 5 to 15 pages. For more complex decisions with detailed grounds, allow one week. If your matter is urgent, for example a freezing order to be executed quickly or an imminent appeal deadline, flag this when requesting your quote.
