Parallel Proceedings Strategy in Belgium

A parallel proceedings strategy in Belgium involves running two or more legal actions simultaneously - across different courts, jurisdictions, or legal orders - to maximise pressure on an opponent, protect assets, or secure a faster remedy. Belgium';s position at the crossroads of EU law, its dense treaty network, and its sophisticated commercial courts make it a particularly effective venue for coordinated multi-forum litigation. This guide explains how parallel proceedings work in Belgium, when they are appropriate, what procedural rules govern them, how to manage conflicts between forums, and what enforcement looks like in practice.

Parallel proceedings is the deliberate use of more than one legal forum at the same time to advance a client';s position. In Belgium, this typically takes one of three forms.

The first is vertical parallelism: a domestic Belgian action running alongside proceedings before an EU institution, an international arbitral tribunal, or a foreign court. The second is horizontal parallelism: simultaneous actions before different Belgian courts - for example, a summary injunction before the president of the commercial court while a full merits case proceeds before the same court';s ordinary chamber. The third is cross-border parallelism: coordinated proceedings in Belgium and one or more other EU member states, exploiting the Brussels I Recast Regulation to determine which court has priority.

Each form requires a different strategic logic. Vertical parallelism is often used to create regulatory or reputational pressure alongside a private law claim. Horizontal parallelism is used when speed and interim relief matter as much as the final judgment. Cross-border parallelism is used when assets, parties, or performance obligations are spread across multiple countries.

A common mistake is treating parallel proceedings as a purely tactical device without a coherent legal theory connecting the forums. Belgian courts, and particularly the Court of Cassation, have shown willingness to sanction abuse of process where parallel actions appear designed solely to harass rather than to advance a legitimate legal interest.

Belgium';s court system is organised under the Judicial Code (Code judiciaire / Gerechtelijk Wetboek), which governs civil and commercial procedure. The commercial courts (tribunaux de l';entreprise / ondernemingsrechtbanken), established by the reform of the Code of Companies and Associations, handle most business disputes. The civil courts of first instance retain jurisdiction over matters outside commercial competence.

For cross-border disputes within the EU, the Brussels I Recast Regulation (EU Regulation 1215/2012) is the primary instrument. It establishes rules on jurisdiction, lis pendens, and the recognition and enforcement of judgments. Under Article 29 of that regulation, where proceedings involving the same cause of action and the same parties are brought in courts of different member states, any court other than the court first seised must stay its proceedings until the jurisdiction of the first court is established. This lis pendens rule is central to any cross-border parallel proceedings strategy in Belgium.

Belgian courts apply the lis pendens doctrine strictly. The Court of Cassation has confirmed that the rule applies even where the legal basis of the claims differs, provided the underlying facts and parties are substantially the same. This means a party wishing to run parallel EU proceedings must time its filings carefully to ensure the preferred forum is seised first.

For proceedings outside the EU, Belgium applies its Private International Law Code (loi du 16 juillet 2004 portant le Code de droit international privé). This code governs jurisdiction, applicable law, and recognition of foreign judgments in non-EU matters. It allows Belgian courts to decline jurisdiction on forum non conveniens grounds in limited circumstances, though Belgian courts apply this doctrine more narrowly than common law jurisdictions.

In practice, founders and international businesses should consider that Belgium';s commercial courts are experienced with multi-jurisdictional disputes. The Brussels commercial court in particular handles a high volume of EU-related commercial litigation and is familiar with coordinating its proceedings with those of foreign courts.

A well-designed parallel proceedings strategy in Belgium starts with a clear map of the available forums, the remedies each can grant, and the timing constraints that apply.

The first decision point is the choice of anchor forum. The anchor is the court or tribunal where the primary merits dispute will be resolved. In Belgium, this is usually the competent commercial court. The anchor forum determines the applicable procedural rules, the standard of proof, and the timeline to judgment. Belgian commercial courts typically reach a first-instance judgment in a contested commercial matter within 12 to 24 months, depending on complexity and the court';s docket.

The second decision point is the choice of interim relief forum. Belgium';s kort geding procedure - the summary proceedings before the president of the commercial court - allows a party to obtain interim injunctions, asset freezes, or provisional measures within days or weeks. The president can grant relief on an urgent basis without prejudging the merits. This makes the kort geding an essential tool in any parallel proceedings strategy where speed matters.

The third decision point is the arbitration interface. Where the underlying contract contains an arbitration clause, a party must decide whether to initiate arbitration, seek interim relief from a Belgian court in support of the arbitration, or challenge the validity of the arbitration clause before the courts. Belgian law, following the UNCITRAL Model Law as incorporated in the Belgian Judicial Code, allows courts to grant interim measures even where arbitration is pending or agreed upon.

The fourth decision point is asset location. If the opponent holds assets in Belgium, a Belgian court can issue a conservatory attachment (saisie conservatoire / bewarend beslag) without prior notice. This is one of the most powerful tools available and can be combined with proceedings on the merits in another jurisdiction.

A non-obvious requirement is that Belgian conservatory attachments require authorisation from the attachment judge (juge des saisies / beslagrechter). The applicant must demonstrate a degree of urgency and a prima facie claim. The threshold is not high, but the procedural steps must be followed precisely.

The most technically demanding aspect of a parallel proceedings strategy in Belgium is managing the risk that two forums reach conflicting decisions. This risk is real and must be addressed proactively.

Within the EU, the Brussels I Recast Regulation provides the main conflict-resolution mechanism through lis pendens and related actions rules. Under Article 30, where related actions are pending in courts of different member states, any court other than the court first seised may stay its proceedings. "Related actions" is defined broadly: actions are related where they are so closely connected that it is expedient to hear and determine them together to avoid irreconcilable judgments. Belgian courts have applied this provision to stay domestic proceedings pending the outcome of related EU proceedings, and vice versa.

Outside the EU, conflict management is more complex. The Belgian Private International Law Code allows a Belgian court to stay proceedings where a foreign court is already seised of the same dispute, but only if the foreign judgment will be recognisable in Belgium and the foreign court can resolve the dispute within a reasonable time. In practice, Belgian courts are reluctant to stay proceedings in favour of non-EU courts unless the connection to Belgium is weak.

A common mistake in cross-border parallel proceedings is failing to monitor the procedural status of the foreign action. Belgian courts will lift a stay if the foreign proceedings stall or if the foreign court declines jurisdiction. Counsel must maintain active oversight of all forums simultaneously.

Where arbitration and court proceedings run in parallel, the risk of conflicting interim orders is particularly acute. Belgian courts have jurisdiction to grant interim relief in support of arbitration under Article 1683 of the Judicial Code, but they will generally defer to the arbitral tribunal on substantive matters once the tribunal is constituted. Coordinating the timing of court applications and arbitral requests for interim measures requires careful sequencing.

In practice, founders should consider appointing a coordinating counsel - a single lawyer or firm with visibility across all forums - to manage the sequencing of filings, monitor deadlines, and ensure that arguments made in one forum do not create estoppel or inconsistency problems in another.

Enforcement is the ultimate test of any parallel proceedings strategy. A judgment or award that cannot be enforced is of limited value, and Belgium';s enforcement framework has specific features that affect strategic choices.

Belgian judgments in civil and commercial matters are enforced through the bailiff (huissier de justice / gerechtsdeurwaarder) system. Once a judgment is final and executory, the creditor can instruct a bailiff to levy execution on the debtor';s assets in Belgium. The process is generally efficient, though debtors can challenge enforcement on procedural grounds.

Foreign EU judgments benefit from automatic recognition and enforcement under the Brussels I Recast Regulation. Since the abolition of the exequatur procedure for EU judgments, a creditor holding a judgment from another EU member state can enforce it in Belgium directly, using a standard certificate issued by the court of origin. This makes Belgium an attractive enforcement jurisdiction for EU-wide parallel proceedings strategies.

Foreign non-EU judgments require exequatur proceedings before a Belgian court of first instance. The court will verify that the foreign judgment meets the conditions set out in the Private International Law Code: the foreign court had jurisdiction, the judgment is final, it does not violate Belgian public policy, and the defendant';s procedural rights were respected. The exequatur process typically takes several months.

Arbitral awards are enforced in Belgium under the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, to which Belgium is a party. The enforcement procedure requires an application to the court of first instance. Belgian courts have a strong record of enforcing foreign arbitral awards and apply the public policy exception narrowly.

A practical scenario illustrates the enforcement dimension. A German company obtains an interim injunction from a Belgian commercial court against a Belgian distributor, while simultaneously pursuing arbitration in Paris under an ICC clause. The Belgian injunction is immediately enforceable in Belgium. When the Paris award is issued, the German company can enforce it in Belgium through the New York Convention procedure. The two enforcement tracks run in parallel, maximising pressure on the distributor.

A second scenario involves a Belgian company seeking to recover assets from a counterparty with holdings in both Belgium and the Netherlands. The Belgian company obtains a conservatory attachment in Belgium and simultaneously files for a European Account Preservation Order (EAPO) under EU Regulation 655/2014, which allows freezing of bank accounts across EU member states without prior notice to the debtor. The EAPO and the Belgian attachment together cover the counterparty';s liquid assets in both jurisdictions, preventing dissipation while the merits case proceeds.

Running parallel proceedings in Belgium requires strict attention to procedural formalities. Errors in service, timing, or document format can undermine an otherwise sound strategy.

Service of process in Belgium follows the rules of the Judicial Code. Domestic service is effected by bailiff. For international service within the EU, the EU Service Regulation (EU Regulation 1784/2020) applies. For non-EU service, Belgium is a party to the Hague Convention on the Service Abroad of Judicial and Extrajudicial Documents. Counsel must verify the applicable instrument for each forum and ensure that service is effected correctly and documented.

Limitation periods in Belgium are governed by the Civil Code as amended by the reform of the law of obligations. The general limitation period for contractual claims is ten years. For tort claims, the period is five years from the date the claimant knew or should have known of the damage and the identity of the liable party. In a parallel proceedings strategy, limitation periods must be monitored across all forums simultaneously, as the period may run differently in each jurisdiction.

Language requirements are a non-obvious compliance issue. Belgium has three official languages - French, Dutch, and German - and the language of proceedings depends on the location of the court and the parties involved. Commercial courts in Brussels operate in French or Dutch depending on the language of the underlying contract or the registered seat of the parties. Filings in the wrong language can be rejected or cause delay.

Court fees in Belgium are moderate by EU standards. The registration tax (droit de mise au rôle / rolrecht) is payable on filing. Legal representation costs vary widely depending on the complexity of the matter and the seniority of counsel. In multi-forum proceedings, professional fees accumulate across all forums and can represent a significant portion of the total cost. Many underestimate the coordination overhead - the time spent managing communications between counsel in different jurisdictions - which adds to the overall cost without always being visible in advance.

Can a Belgian court issue interim relief in support of foreign arbitration proceedings?

Yes. Under Article 1683 of the Belgian Judicial Code, Belgian courts retain jurisdiction to grant provisional and conservatory measures even where the parties have agreed to arbitrate and even where the arbitral tribunal is already constituted. The court will not prejudge the merits of the arbitral dispute but can freeze assets, issue injunctions, or order disclosure to preserve the effectiveness of the eventual award. The applicant must demonstrate urgency and a prima facie case. This makes Belgian courts a useful support forum for international arbitrations where the opponent holds assets in Belgium, regardless of the seat of the arbitration.

How long does it typically take to obtain interim relief in Belgium, and what does it cost?

The kort geding procedure before the president of the commercial court is designed for speed. In urgent cases, a hearing can be scheduled within a few days of filing. The president can issue an order at the hearing or within a short period thereafter. For conservatory attachments, the attachment judge can authorise the measure ex parte, often within 24 to 48 hours of application. Professional fees for interim proceedings vary depending on complexity, but they are generally lower than for full merits proceedings. State fees are modest. The main cost driver is the preparation of the application and supporting evidence, which must be thorough enough to meet the prima facie threshold.

When is it better to consolidate proceedings in one forum rather than run parallel actions?

Consolidation is preferable when the legal issues are tightly interconnected and a single judgment will resolve all disputes cleanly, when the cost of running multiple forums outweighs the strategic benefit, or when there is a real risk that parallel proceedings will produce conflicting decisions that are difficult to reconcile. Parallel proceedings add value when different forums offer different remedies - for example, interim relief in Belgium combined with merits arbitration elsewhere - or when the opponent has assets in multiple jurisdictions that need to be frozen simultaneously. The decision should be made after a careful analysis of the available remedies, the opponent';s asset profile, and the risk of procedural conflict.

A parallel proceedings strategy in Belgium can deliver significant advantages - faster interim relief, multi-jurisdictional asset protection, and coordinated pressure across forums - but it requires precise execution. The Brussels I Recast Regulation, the Belgian Judicial Code, and the Private International Law Code together create a sophisticated framework that rewards careful planning and penalises procedural errors.
