A foreign supplier discovers that its Belgian distributor has stopped paying invoices, is diverting clients, and shows signs of insolvency. Every week of delay allows assets to disappear and the contractual position to erode. In Belgium, acting quickly – and correctly – within the commercial litigation system is the difference between recovering value and writing off the loss entirely.
Commercial litigation in Belgium is governed by civil procedure rules administered through a network of specialised commercial courts. Claimants must file a formal statement of claim before the competent court, which then manages the case through written submissions, hearings, and judgment. Depending on complexity, first-instance proceedings resolve in roughly twelve to thirty-six months, with enforcement of judgments available immediately on a final ruling.
This page covers the key legal instruments available to international businesses pursuing commercial claims in Belgium, the practical realities of Belgian court procedure. Common pitfalls that cost foreign claimants dearly. Additionally, the cross-border dimension connecting Belgian litigation to EU enforcement mechanisms and Portuguese civil law practice.
The Belgian commercial litigation environment
Belgium operates a civil law system built on the Napoleonic tradition. Its judicial architecture channels business disputes through dedicated commercial divisions – the tribunal de l'entreprise (enterprise court) – which sit in each judicial district and handle disputes between traders, companies, and professional parties.
Belgian civil procedure rules establish a largely written process. Parties exchange successive sets of written submissions before any oral hearing takes place. This differs sharply from common law litigation, where oral advocacy often dominates. International clients accustomed to English or Irish procedure regularly underestimate how much of a Belgian case is decided on paper.
The substantive law underpinning most commercial claims draws on Belgian commercial legislation, contract law, and corporate legislation. Belgian courts also apply EU regulations directly, which matters considerably for cross-border claims involving parties in other member states. Regulation on jurisdiction and recognition of judgments across the EU shapes where a dispute may be litigated and how a Belgian judgment can later be enforced abroad.
Time limits under Belgian civil procedure are strict. A claimant who misses a prescriptive deadline loses the right to bring the claim entirely. For contractual disputes, prescription periods under Belgian commercial legislation are generally shorter than many international clients expect. Identifying the correct period – and interrupting prescription before it expires – is one of the first tasks any practitioner must address.
A non-obvious risk arises from the Belgian concept of abus de droit (abuse of rights), which courts apply when a party exercises a contractual or procedural right in a disproportionate manner. A claimant who demands performance in circumstances that cause clearly excessive prejudice to the counterparty may find its claim reduced or reframed by the court, even when the contractual right itself is unambiguous. This doctrine has no direct equivalent in most common law systems and catches many foreign litigants off guard.
Key instruments and procedural steps
Belgian commercial litigation offers several distinct tools. Choosing the right one – and sequencing them correctly – materially affects both outcome and cost.
The main proceedings (fond). The standard route is a plenary action on the merits, initiated by issuing a citation (court summons) served through a bailiff. The claimant then files a statement of claim setting out the factual basis, legal grounds, and relief sought. The defendant responds in writing within court-set deadlines. After several rounds of written exchange, the court fixes an oral hearing, though in commercial matters the hearing is frequently brief. Judgment follows within weeks or months of the hearing.
Practical note: the written submissions carry almost all the argumentative weight. A poorly drafted initial statement of claim is difficult to cure later, because Belgian procedure limits the extent to which new claims and arguments can be introduced after the process begins.
Interim injunction (référé). Where urgency exists, a claimant may apply to the president of the enterprise court for an interim injunction. This is an expedited procedure producing a provisional order – typically within days to a few weeks. The applicant must demonstrate urgency and a prima facie case. The relief is provisional: it does not determine the merits and does not prevent the losing party from opening full proceedings on the substance. An interim injunction is particularly powerful for freezing assets, stopping a competitor from using disputed intellectual property, or compelling a party to perform a specific act pending trial.
A common mistake is treating the interim injunction as a substitute for main proceedings. It is not. Courts are alert to claimants who use the procedure to obtain what is effectively a final remedy without full merits scrutiny. Overreach in the summary court can damage credibility in the subsequent plenary action.
Attachment before judgment (saisie conservatoire). Belgian civil procedure permits a creditor, with leave of the court, to attach the debtor's assets before obtaining a final judgment. This is a powerful pre-emptive tool. The conditions are specific: the creditor must demonstrate a debt that appears certain, liquid, and due, and must show circumstances suggesting the debtor may dissipate or conceal assets. Attachment is obtained ex parte – the debtor is not heard in advance. Once assets are attached, the creditor must commence main proceedings within a short prescribed period or the attachment lapses.
For international clients dealing with a Belgian counterparty showing signs of financial difficulty, early attachment is often the most important single step. Practitioners advise assessing this option immediately on becoming aware of non-payment or suspicious asset movements.
Payment order procedure (procédure en injonction de payer). For undisputed monetary claims, Belgian law provides a simplified payment order mechanism. The procedure is administrative rather than adversarial. If the debtor does not oppose the order within the prescribed period, the order becomes enforceable without a full hearing. Where the debtor does oppose, the case reverts to ordinary proceedings. This tool suits high-volume, lower-value commercial debt where the counterparty has no genuine defence.
Court filing fees in Belgium are calculated by reference to the value of the claim. Legal fees depend on the complexity of the matter and the volume of written work involved. For significant commercial disputes – typically those above the threshold where enterprise court jurisdiction is mandatory – total legal and procedural costs run into thousands of euros at minimum. With complex multi-party litigation reaching considerably more. Realistic cost budgeting at the outset avoids the situation where a claimant abandons proceedings mid-way because the economics no longer support continuation.

Practical pitfalls for international claimants
Belgian commercial litigation has several features that regularly produce adverse surprises for foreign parties acting without specialist counsel.
Language of proceedings. Belgium has three official language regions: French-speaking (Wallonia and Brussels), Dutch-speaking (Flanders), and German-speaking (a small eastern region). The language of court proceedings is determined by the territorial jurisdiction of the court, not by the parties' preference. A claimant who files in the wrong language region, or whose documents are not in the correct language, faces procedural sanctions including dismissal. Critically, the choice of where to file – and in which language – must be considered before any document is prepared.
Incorrect identification of the competent court. Belgian civil procedure allocates jurisdiction between courts by subject matter, value, and territory. Filing before an incompetent court wastes time and triggers a referral, during which prescription may continue to run against the claimant. The enterprise court has broad but not unlimited jurisdiction: certain disputes fall to the general civil court or to specialist tribunals. Misidentification is a recurring error for non-Belgian practitioners.
Underestimating the evidential burden in writing. Because Belgian courts rely on written submissions, parties must anticipate and respond to every factual and legal argument in their written pleadings. Reserving arguments for oral hearing – as one might in a common law trial – leaves positions unexpressed and unrecorded. Courts do not typically ask counsel to develop arguments not foreshadowed in the written file.
Failing to consider mediation before litigation. Belgian law has progressively integrated mediation into the commercial dispute resolution system. Courts may invite parties to consider mediation at any stage. More significantly, some contractual dispute resolution clauses require a mediation step before litigation. Overlooking this requirement can give the opposing party a procedural weapon to delay proceedings substantially.
Ignoring the risk of counterclaims. Belgian civil procedure permits defendants to file counterclaims in the same proceedings. A claimant who initiates litigation without fully auditing its own contractual compliance may face a well-founded counterclaim that complicates or neutralises the original action.

Cross-border and strategic considerations
Belgium sits at the centre of EU institutional life and is a party to the full range of EU instruments governing cross-border litigation. This creates both tools and obligations for international claimants.
EU jurisdiction rules. EU civil procedure regulation determines which member state's courts have jurisdiction when the defendant is domiciled in an EU state. Belgian courts have jurisdiction if the defendant is domiciled in Belgium, if the contract was to be performed in Belgium, or if the parties have agreed to Belgian jurisdiction in their contract. A carefully drafted jurisdiction clause in commercial contracts – expressly designating Belgian courts and Belgian law – prevents disputes about where to litigate and removes the risk of parallel proceedings in multiple jurisdictions.
Recognition and enforcement of Belgian judgments in the EU. A final Belgian court judgment is enforceable across all EU member states under EU civil procedure regulation. Without the need for a separate exequatur (recognition) procedure in most cases. This makes a Belgian judgment a powerful instrument for creditors with assets spread across Europe. Practitioners pursuing cross-border recovery regularly use Belgium as a preferred jurisdiction precisely because of the automatic enforceability of its judgments within the EU.
The Portuguese connection. For clients operating between Belgium and Portugal. a common pattern for Iberian businesses with Belgian trading partners or holding structures. a Belgian judgment is enforceable in Portugal under EU regulation directly, without additional recognition proceedings. Conversely, a Portuguese judgment obtained through the Portuguese civil procedure system (governed by the Código de Processo Civil – the Portuguese code of civil procedure) is equally enforceable in Belgium. This bilateral enforceability under EU rules removes one of the historical obstacles to cross-border recovery. Our analysis of commercial disputes in Portugal details how Portuguese courts handle similar commercial claims.
Strategic choice between litigation and arbitration. International commercial contracts often include arbitration clauses. Where a dispute falls within the scope of an arbitration agreement, Belgian courts will decline jurisdiction and refer the parties to arbitration. Belgium is an arbitration-friendly jurisdiction; awards issued under arbitration rules in Belgium benefit from a well-established enforcement regime. For parties weighing whether to pursue arbitration or litigation in Belgium, the key variables are confidentiality, speed, the importance of appellate review, and the enforceability of the final award in the debtor's home jurisdiction. Neither route is universally superior – the choice must be made on the facts of each matter.
Insolvency intersection. Where a Belgian counterparty is insolvent or approaching insolvency, commercial litigation strategy must integrate insolvency law. Belgian insolvency legislation provides mechanisms for challenging transactions entered into in the period before formal insolvency. A creditor who obtains a judgment – and enforces it – shortly before the debtor enters insolvency proceedings may face a challenge to that enforcement under preference rules. Understanding the intersection between commercial litigation and insolvency law is essential for any creditor pursuing a financially distressed Belgian entity.

Self-assessment checklist
Commercial litigation in Belgium is the appropriate path if the following conditions apply:
- The counterparty is domiciled or has assets in Belgium, or the contract designates Belgian jurisdiction.
- The claim is for a value that justifies the costs of Belgian court proceedings – typically disputes of meaningful commercial value where the economics of litigation are positive.
- Prescription has not expired, or steps have already been taken to interrupt it.
- The contractual dispute resolution clause has been satisfied (mediation or notice requirements met).
- Key documents – contract, correspondence, invoices – are available and can be produced in the required language.
Before initiating proceedings, verify the following:
- Correct identification of the competent court by subject matter, value, and territory.
- Language region of the court and language in which documents must be filed.
- Whether an interim injunction or pre-judgment attachment is needed to protect the position immediately.
- Availability and admissibility of all key evidence in written form.
- Whether the counterparty has commenced insolvency proceedings or shows indicators of financial distress.
If the counterparty has assets in both Belgium and other EU states, consider whether parallel enforcement steps in multiple jurisdictions are warranted alongside Belgian proceedings. A detailed guide to related procedures is available in our guide to business operations in Belgium.
Frequently asked questions
- How long does commercial litigation in Belgium typically take from filing to judgment?
- First-instance proceedings before the enterprise court generally take between twelve and thirty-six months, depending on the complexity of the case and the court's workload in the relevant district. Straightforward monetary claims on undisputed facts move faster. Multi-party or technically complex disputes – for example those involving expert evidence – sit toward the upper end of that range. Appeals to the court of appeal add further time. Engaging a lawyer in Belgium with experience of the specific court helps in calibrating realistic timelines at the outset.
- Is it necessary to attempt mediation before commencing litigation in Belgium?
- Not as a universal requirement, but it depends on the contract and the specific dispute. Belgian commercial legislation has progressively encouraged mediation, and courts may suggest it at any point. More importantly, many commercial contracts include a tiered dispute resolution clause requiring mediation or negotiation before litigation. Failing to follow that clause gives the defendant a ground to seek a stay of proceedings. Claimants should review their contractual dispute resolution provisions before filing any court document.
- Can a Belgian judgment be enforced in Portugal or elsewhere in the EU without additional court proceedings?
- Yes. Under EU civil procedure regulation, a final and enforceable Belgian court judgment is recognised and enforceable across all EU member states, including Portugal, without requiring a separate recognition procedure in the enforcement state. The creditor applies directly to the competent enforcement authority in the target jurisdiction, presenting the Belgian judgment together with a standard certificate. This cross-border enforceability is one of the most significant practical advantages of obtaining judgment through a Belgian law firm with EU-wide enforcement experience.
