Belgium sits at the intersection of three legal traditions - French, Dutch and German - and its dispute resolution landscape reflects that complexity. Companies operating in or through Belgium face a choice between state court litigation, institutional arbitration and a growing range of alternative dispute resolution mechanisms, each with distinct procedural logic, timelines and cost profiles. Getting that choice wrong at the outset can cost months of delay and significant legal spend. This article maps the full landscape: the court structure, the arbitration framework, pre-trial obligations, enforcement mechanics and the practical traps that catch international clients most often.
Belgium's judicial system is organised in three tiers. The Courts of First Instance (Rechtbank van eerste aanleg / Tribunal de première instance) handle general civil matters. The Enterprise Courts (Ondernemingsrechtbank / Tribunal de l'entreprise) are the primary venue for commercial disputes between businesses, including contract claims, corporate conflicts and insolvency-adjacent litigation. The Courts of Appeal (Hof van Beroep / Cour d'appel) sit above both, and the Court of Cassation (Hof van Cassatie / Cour de cassation) reviews questions of law only, not facts.
The Enterprise Courts were created by the Act of 15 April 2018 reforming company and association law, replacing the former Commercial Courts. Their jurisdiction covers disputes between undertakings, regardless of whether the subject matter is commercial in the traditional sense. An undertaking is defined broadly under the Belgian Code of Economic Law (Wetboek van economisch recht / Code de droit économique) to include any natural or legal person pursuing an economic activity on a durable basis. This means that even a professional services firm or a non-profit with commercial activities can be brought before the Enterprise Court.
Territorial jurisdiction follows the general rule in the Belgian Judicial Code (Gerechtelijk Wetboek / Code judiciaire): the defendant's registered seat or domicile determines the competent court. Parties may derogate from this rule by written agreement, subject to the limits imposed by mandatory consumer and employment law provisions. For cross-border disputes within the EU, Regulation (EU) No 1215/2012 (Brussels I Recast) governs jurisdiction and recognition, making Belgium's courts directly accessible to claimants from other member states without a separate exequatur procedure for enforcement of judgments within the EU.
A non-obvious risk for international clients is the language regime. Belgium has three official procedural languages - Dutch, French and German - assigned by territory. Proceedings in Antwerp are conducted in Dutch; proceedings in Liège in French. Filing documents in the wrong language is not merely a formality issue: it can result in the case being transferred or, in extreme cases, procedural nullity under Article 40 of the Judicial Code.
Belgian procedural law does not impose a universal mandatory mediation requirement before filing a claim, but the landscape is shifting. The Act of 18 June 2018 on various civil and procedural provisions introduced a reinforced framework for mediation and conciliation. Since then, judges have broad discretion under Article 731 of the Judicial Code to refer parties to mediation at any stage of proceedings, including at the very first hearing.
More practically, many commercial contracts governed by Belgian law include escalation clauses requiring negotiation, then mediation, before arbitration or litigation. Belgian courts enforce these clauses strictly. A party that files a claim in breach of a multi-tier dispute resolution clause risks having the proceedings stayed until the contractual pre-conditions are met. The cost of ignoring this is not just delay - it can undermine the claimant's position on costs at the end of the case.
The Belgian Centre for Arbitration and Mediation (CEPANI - Centre belge d'arbitrage et de médiation) administers both arbitration and mediation proceedings. CEPANI mediation typically runs over four to eight weeks and costs a fraction of full arbitration. For disputes in the low to mid six-figure range, a successful CEPANI mediation can save both parties from a process that might otherwise run two to three years in the state courts.
Practical scenarios illustrate the stakes. A Dutch distributor seeking payment from a Belgian manufacturer under a contract with a CEPANI mediation clause that files directly in the Enterprise Court will face an immediate challenge to admissibility. A Belgian subsidiary of a US group that skips the internal escalation procedure before commencing arbitration may find its claim time-barred by the time the procedural defect is corrected. A mid-size technology company disputing a software licence with a Belgian public authority must first exhaust the administrative complaint procedure before any court can hear the case.

Once a claim is filed, the Belgian procedural framework is governed primarily by the Judicial Code, which was substantially amended by the Pot-pourri reform laws between 2015 and 2018. The reforms aimed to accelerate proceedings, but state court litigation in Belgium still moves at a pace that surprises international clients accustomed to common law jurisdictions.
After filing the introductory writ (dagvaarding / citation), the case is assigned to a chamber of the Enterprise Court. The parties exchange written submissions - conclusions (conclusies / conclusions) - according to a timetable set by the court. Belgian procedural law allows three rounds of written submissions as a default, though parties can agree to fewer. Each round typically takes two to four months, meaning the written phase alone can last six to twelve months for a contested commercial dispute.
The oral hearing (pleidooien / plaidoiries) follows the written phase. Belgian courts do not conduct extensive witness examination in the common law sense. Evidence is primarily documentary. Expert witnesses are court-appointed rather than party-appointed, which is a fundamental difference from English or American practice. Under Article 962 of the Judicial Code, a judge may appoint a technical expert at any stage; the expert's report carries significant weight and the process adds three to six months to the timeline.
First-instance judgments in commercial matters typically take twelve to twenty-four months from filing to decision, depending on complexity and the court's caseload. Appeals add another twelve to eighteen months. Enforcement of a Belgian judgment against a Belgian defendant is relatively straightforward through the bailiff (gerechtsdeurwaarder / huissier de justice) system, including attachment of bank accounts and movable assets under Articles 1445 and following of the Judicial Code.
Costs in Belgian litigation have two components: lawyers' fees and procedural indemnities (rechtsplegingsvergoeding / indemnité de procédure). The procedural indemnity is a fixed contribution toward the winning party's legal costs, set by Royal Decree on a scale linked to the amount in dispute. It does not cover actual legal fees, which for a contested commercial case before the Enterprise Court typically start from the low thousands of euros for straightforward matters and rise substantially for complex multi-party disputes. Lawyers in Belgium generally bill by the hour, with rates varying by seniority and firm size.
A common mistake made by international clients is underestimating the procedural indemnity mechanism. Losing a case in Belgium does not expose a party to full costs recovery as in England, but the indemnity can still represent a meaningful sum in high-value disputes. Conversely, winning parties sometimes expect full fee recovery and are disappointed when the indemnity covers only a fraction of their actual spend.
Belgium has positioned itself as an arbitration-friendly jurisdiction. The Belgian Arbitration Act (Part VI of the Belgian Judicial Code, Articles 1676 to 1722) is based on the UNCITRAL Model Law, with adaptations. The Act was substantially revised in 2013 to align with international best practice and to make Belgium more competitive as a seat for international arbitration.
The key features of the Belgian arbitration framework are worth examining in detail.
CEPANI is the primary institutional arbitration body in Belgium. Its Rules, last revised in 2020, provide for expedited proceedings for disputes below EUR 1 million, with a target timeline of six months from constitution of the tribunal to award. Standard CEPANI proceedings typically conclude in twelve to eighteen months. CEPANI arbitrators are drawn from a panel of experienced practitioners and academics, and proceedings can be conducted in any language agreed by the parties.
Ad hoc arbitration under UNCITRAL Rules is also available, with Brussels frequently chosen as the seat. The Belgian courts' track record of supporting arbitration - refusing to hear claims brought in breach of arbitration clauses, granting anti-suit injunctions in appropriate cases and enforcing awards with minimal formality - reinforces Brussels' reputation as a reliable arbitral seat.
For enforcement of foreign arbitral awards in Belgium, the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (1958) applies. Belgium ratified the Convention without reservations. Enforcement is sought through the President of the Court of First Instance, who applies the limited grounds for refusal set out in Article V of the Convention. In practice, enforcement of awards from reputable arbitral institutions against Belgian-domiciled defendants proceeds within two to four months absent a serious challenge.

Beyond arbitration, Belgian law provides a structured framework for alternative dispute resolution that international businesses frequently overlook. The Act of 21 February 2005 incorporating mediation into the Judicial Code created a regulated profession of accredited mediators (erkende bemiddelaars / médiateurs agréés) supervised by the Federal Mediation Commission (Federale Bemiddelingscommissie / Commission fédérale de médiation).
Accredited mediation in Belgium has a specific legal consequence: agreements reached in mediation and homologated by a court under Article 1733 of the Judicial Code acquire the force of a court judgment and are directly enforceable. This makes Belgian mediated settlements significantly more powerful than informal settlement agreements, which remain contractual and require separate enforcement proceedings if breached.
Expert determination (deskundigenonderzoek / expertise) is widely used in Belgian construction, technology and valuation disputes. The parties appoint a neutral technical expert who renders a binding or non-binding opinion on a specific factual or technical question. Expert determination is faster and cheaper than full arbitration for disputes where the core issue is technical rather than legal. A construction defect dispute involving a claim in the mid six figures can often be resolved through expert determination in three to five months at a fraction of the cost of arbitration.
Binding advice (bindend advies / avis contraignant) is a contractual mechanism under which the parties agree in advance to be bound by the opinion of a named expert or panel on a specific category of disputes - typically price adjustments, earn-out calculations or valuation disagreements in M&A transactions. Belgian courts enforce binding advice clauses strictly, treating the expert's determination as final on the agreed scope unless there is manifest error or fraud.
The practical choice between these mechanisms depends on the nature of the dispute, the relationship between the parties and the need for enforceability. A dispute between long-term commercial partners over a contract interpretation question is well-suited to mediation. A technical dispute over construction defects or software performance is better resolved through expert determination. A valuation dispute in a share purchase agreement is the natural territory for binding advice. Litigation or arbitration becomes necessary when the relationship has broken down entirely, when interim relief is needed urgently or when the amount at stake justifies the procedural investment.
Belgium's position as the de facto capital of the European Union gives its courts and arbitral institutions a particular relevance for cross-border commercial disputes. The Brussels I Recast Regulation creates a seamless enforcement mechanism for Belgian court judgments across EU member states, without the need for a separate recognition procedure. A judgment of the Brussels Enterprise Court can be enforced in Paris, Amsterdam or Warsaw on the same basis as a domestic judgment in those jurisdictions.
For disputes involving non-EU counterparties, enforcement of Belgian court judgments depends on bilateral treaties or the rules of the foreign jurisdiction. Belgium has concluded bilateral judicial cooperation treaties with a number of states, but coverage is uneven. Where enforcement outside the EU is a realistic concern, arbitration with a New York Convention award is structurally superior to litigation, because the Convention's 170-plus signatory states provide a far broader enforcement network than any bilateral treaty framework.
Interim relief in Belgian proceedings deserves separate attention. The President of the Enterprise Court has jurisdiction to grant urgent interim measures in summary proceedings (kort geding / référé), including injunctions, asset freezes and orders for specific performance, under Article 584 of the Judicial Code. These proceedings move quickly - a hearing can be obtained within days in urgent cases - and the threshold is urgency plus a prima facie case (fumus boni iuris). The interim order does not prejudge the merits, but in practice a well-obtained injunction significantly shifts the negotiating dynamic.
A non-obvious risk in Belgian cross-border litigation is the interaction between Belgian procedural law and EU data protection rules. Discovery-style document production, common in US or English proceedings, is not part of Belgian civil procedure. Belgian courts order document production only in specific, targeted circumstances under Article 877 of the Judicial Code. International clients who expect broad disclosure will be disappointed, and those who design their litigation strategy around obtaining documents through Belgian proceedings will need to recalibrate.
Three practical scenarios illustrate the strategic calculus. A German manufacturer with a EUR 2 million claim against a Belgian distributor for unpaid invoices should consider whether the distributor has Belgian assets sufficient to justify state court proceedings, or whether a CEPANI arbitration clause in the distribution agreement makes arbitration the faster path to an enforceable award. A Singapore-based investor disputing a joint venture agreement with a Belgian partner over a EUR 10 million earn-out should evaluate binding advice or CEPANI arbitration rather than state court litigation, given the technical valuation issues involved. A Belgian subsidiary facing a EUR 500,000 claim from a former employee should note that employment disputes fall outside the Enterprise Court's jurisdiction and are heard by the Labour Tribunals (Arbeidsrechtbank / Tribunal du travail) under a separate procedural regime.
The business economics of the decision are straightforward. State court litigation in Belgium for a contested commercial claim in the EUR 500,000 to EUR 5 million range will typically involve legal fees starting from the low tens of thousands of euros for a straightforward case, rising to six figures for complex multi-party proceedings. CEPANI arbitration involves administrative fees on a scale linked to the amount in dispute, plus arbitrators' fees, making it more expensive than litigation for small claims but often faster and more predictable for mid-to-large disputes. Mediation and expert determination are the most cost-efficient options where the parties retain sufficient trust to engage constructively.
The risk of inaction is concrete. Belgian limitation periods (verjaringstermijnen / délais de prescription) under the Civil Code (Burgerlijk Wetboek / Code civil) were reformed by the Act of 22 July 2018, which introduced a general ten-year limitation period for contractual claims and a five-year period for claims arising from unlawful acts. However, shorter contractual limitation periods are enforceable, and some sector-specific rules impose periods as short as one year. A claimant that delays engaging Belgian counsel while pursuing informal negotiations risks finding its claim time-barred before proceedings are commenced.

What is the main practical risk of choosing Belgian state court litigation over arbitration for a cross-border commercial dispute?
The primary risk is timeline and enforcement geography. Belgian state court proceedings for a contested commercial dispute typically take two to four years from filing to final appeal, and enforcement of the resulting judgment outside the EU requires navigating bilateral treaty frameworks that may not exist with the counterparty's home jurisdiction. Arbitration with a Brussels seat produces an award enforceable under the New York Convention in over 170 states, often in twelve to eighteen months through CEPANI. The choice of forum should be driven by where the counterparty's assets are located and how quickly a binding result is needed, not by familiarity with one system or the other.
How long and how expensive is a typical commercial arbitration in Belgium, and what happens if the losing party refuses to pay?
A standard CEPANI arbitration for a dispute in the EUR 1 to 5 million range typically concludes in twelve to eighteen months. Total costs - administrative fees, arbitrators' fees and legal representation - for both parties combined generally start from the low tens of thousands of euros for straightforward cases and rise with complexity. If the losing party refuses to comply voluntarily, the winning party must seek enforcement through the Belgian courts, which involves a relatively streamlined exequatur procedure before the President of the Court of First Instance. Once the exequatur is granted, the full range of Belgian enforcement mechanisms - bank account attachment, seizure of movable assets, real estate enforcement - becomes available. The enforcement process typically adds two to four months.
When should a business replace arbitration with mediation or expert determination in a Belgian-law dispute?
Arbitration is the right tool when the relationship between the parties has broken down, when a binding and enforceable decision is needed, or when the dispute involves complex legal questions requiring a reasoned award. Mediation is preferable when the parties have an ongoing commercial relationship they wish to preserve, when speed and confidentiality are paramount, and when a negotiated outcome is more valuable than a binary win-lose result. Expert determination is the appropriate mechanism when the core issue is technical or financial - a valuation, a construction defect assessment, a software performance benchmark - rather than a legal dispute about rights and obligations. Many sophisticated Belgian commercial contracts include a tiered clause that moves through negotiation, mediation and then arbitration, reserving litigation for exceptional circumstances.
Belgium offers a mature, internationally oriented dispute resolution ecosystem. State courts, CEPANI arbitration, accredited mediation and expert determination each serve distinct functions, and the choice between them has direct consequences for timeline, cost and enforceability. International businesses operating in Belgium should build their dispute resolution strategy before a dispute arises, not after - selecting the right forum clause, understanding the language regime and mapping their counterparty's assets against the available enforcement mechanisms.
