Asset Tracing, Account Search and Forensic Investigation in Belgium

Asset tracing in Belgium combines civil procedural tools, judicial investigative powers and forensic accounting methods to locate and secure assets before or during enforcement. Belgian law provides creditors with a structured set of mechanisms - from pre-judgment conservatory attachment to court-ordered disclosure - that, when used correctly, can decisively shift the balance in a cross-border dispute. This article maps the legal framework, explains each tool's conditions and limits, identifies the most common mistakes made by foreign creditors, and outlines a practical strategy for protecting a claim in Belgium.

Belgium operates a civil law system rooted in the Judicial Code (Code judiciaire / Gerechtelijk Wetboek), which governs civil procedure, enforcement and conservatory measures. The Judicial Code, together with the Civil Code (Code civil / Burgerlijk Wetboek) and the Code of Economic Law (Code de droit économique / Wetboek van economisch recht), forms the primary legislative architecture for creditor remedies.

Asset tracing in Belgium is not a single procedure but a layered process. At the pre-litigation stage, a creditor may gather evidence through private forensic investigation, notarial acts and voluntary disclosure. Once proceedings are initiated, the court system offers compelled disclosure, conservatory attachment and, in insolvency contexts, court-appointed administrators with broad investigative mandates.

The key judicial actors are the enforcement judge (juge des saisies / beslagrechter), who handles all conservatory and enforcement measures, and the president of the commercial court (président du tribunal de l'entreprise / voorzitter van de ondernemingsrechtbank), who has jurisdiction over urgent interim relief. The Public Prosecutor's Office (Parquet / Parket) and the Financial Intelligence Processing Unit (Cellule de traitement des informations financières / Cel voor Financiële Informatieverwerking, known as CTIF-CFI) play roles in parallel criminal or anti-money-laundering contexts.

A non-obvious risk for foreign creditors is the strict separation between civil and criminal asset tracing in Belgium. Evidence gathered in a criminal investigation is not automatically transferable to civil proceedings, and a creditor who relies on a parallel criminal complaint to locate assets may find that the civil enforcement track has stalled while criminal proceedings move slowly.

Conservatory attachment (saisie conservatoire / bewarend beslag) is the central instrument for freezing assets before a final judgment. Under Article 1413 of the Judicial Code, a creditor may apply for conservatory attachment without prior notice to the debtor, provided three conditions are met: the existence of a claim that is certain, liquid and due (or at least sufficiently arguable at the conservatory stage), a genuine risk of dissipation of assets, and a degree of urgency.

The application is made ex parte to the enforcement judge. The judge may grant the attachment within one to three working days in straightforward cases, though complex or high-value matters may take longer. Once granted, the attachment order is served on the debtor and on any third-party holder of assets - typically a bank - who is then obliged to freeze the relevant accounts or assets immediately.

Belgian banks are required to respond to attachment orders within a short window. The bank must declare the assets it holds for the debtor within a prescribed period, typically fifteen days from service of the attachment. This declaration mechanism is one of the most effective account search tools available to a creditor in Belgium, because it compels disclosure without requiring the creditor to identify specific account numbers in advance.

The conditions of applicability deserve careful attention. A common mistake made by international clients is treating conservatory attachment as automatic once a foreign judgment or arbitral award exists. In practice, a foreign title must first be recognised or declared enforceable in Belgium before it can ground an enforcement attachment (saisie-exécution / uitvoerend beslag). A conservatory attachment, by contrast, can be obtained on the basis of a pending foreign claim, but the creditor must still demonstrate the arguable existence of the claim to the Belgian court's satisfaction.

Costs at this stage are moderate. Court filing fees are relatively low, but legal fees for preparing and arguing an ex parte application typically start from the low thousands of EUR. If the attachment is contested by the debtor - which is common - additional hearings before the enforcement judge will increase costs further.

Locating assets is often harder than freezing them. Belgian law provides several mechanisms for compelling disclosure of financial information, each with different triggers and scope.

The most direct tool is the declaration obligation attached to a conservatory attachment order. Once an attachment is served on a bank or other financial institution, the institution must declare all assets it holds for the named debtor. This effectively transforms the attachment into an account search: the creditor does not need to know in advance which banks the debtor uses, because the order can be served on multiple institutions simultaneously.

A second mechanism is the information order (demande d'information / informatievordering) available in enforcement proceedings under Article 1456 of the Judicial Code. The enforcement judge may order third parties, including banks, employers and public registries, to provide information about the debtor's assets. This power is broader than the attachment declaration and can extend to real estate registries, vehicle registries and shareholding records.

The Central Individual Credit Register (Centrale des crédits aux particuliers / Centrale voor kredieten aan particulieren) and the Central Enterprise Register (Banque-Carrefour des Entreprises / Kruispuntbank van Ondernemingen) are publicly accessible databases that provide useful preliminary intelligence on a debtor's registered activities, corporate affiliations and credit history. These are typically the first resources a forensic team consults before initiating formal proceedings.

For corporate debtors, the Belgian National Bank's (Banque Nationale de Belgique / Nationale Bank van België) annual accounts database contains filed financial statements for most Belgian companies. Gaps or anomalies in filed accounts - late filings, sudden asset reductions, intercompany transfers - are standard forensic indicators of asset dissipation.

In practice, it is important to consider that Belgian banks apply strict confidentiality rules under the Law of 22 March 1993 on the Status and Supervision of Credit Institutions (now largely superseded by prudential legislation implementing EU directives). A bank will not voluntarily disclose account information to a private party without a court order. Attempts by foreign creditors to obtain information through informal channels or letters of request without proper judicial backing are routinely refused and can alert the debtor to the creditor's intentions.

A non-obvious risk is the use of nominee structures or Belgian-registered holding companies to hold assets indirectly. A conservatory attachment served on a bank will freeze accounts held in the debtor's name, but assets held through a subsidiary or a trust-like arrangement (fiducie / fiducie, which has limited recognition in Belgian law) may fall outside the immediate scope of the order. Forensic investigation must therefore map the corporate structure before the attachment strategy is finalised.

Forensic investigation in Belgium encompasses financial analysis, document review, digital forensics and expert witness preparation. It operates at the intersection of private investigation, accounting expertise and legal procedure.

Private investigators in Belgium are regulated by the Law of 19 July 1991 on the Profession of Private Detective (Loi réglementant la profession de détective privé / Wet tot regeling van het beroep van privédetective). Licensed investigators may conduct surveillance, open-source intelligence gathering and document analysis, but they may not access private financial records, intercept communications or conduct covert operations that would constitute criminal offences. Evidence gathered in violation of these limits is inadmissible under the Antigoon doctrine (Antigoon-leer), which the Belgian Court of Cassation (Cour de cassation / Hof van Cassatie) has developed to assess the admissibility of unlawfully obtained evidence in civil proceedings.

The Antigoon doctrine does not automatically exclude unlawfully obtained evidence in civil cases. The court weighs three factors: whether the violation affected the reliability of the evidence, whether the violation infringed a fundamental right, and whether the admission of the evidence would compromise the integrity of the proceedings. This nuanced approach means that some imperfectly obtained evidence may still be admitted, but relying on this possibility is a high-risk strategy that experienced practitioners avoid.

Court-appointed experts (experts judiciaires / gerechtelijke deskundigen) play a central role in Belgian forensic proceedings. Under Article 962 of the Judicial Code, a court may appoint an expert to investigate financial matters, trace transactions or assess the value of assets. The expert's report is not binding on the court but carries significant evidential weight. Parties may appoint their own experts (experts-conseils / partijdeskundigen) to challenge or supplement the court expert's findings.

Digital forensics has become increasingly important in Belgian proceedings. The Law of 25 December 2016 on the Processing of Personal Data in the Criminal Justice Sector and the General Data Protection Regulation (GDPR) impose constraints on how digital evidence is gathered and processed. A creditor conducting internal forensic investigation of a debtor's digital footprint must ensure that data collection methods comply with GDPR requirements, particularly where the investigation involves personal data of individuals associated with the debtor.

Three practical scenarios illustrate how forensic investigation integrates with legal procedure:

• A Belgian subsidiary of a foreign group transfers significant intercompany receivables to a parent shortly before a creditor obtains judgment. Forensic accountants reconstruct the transaction flow using filed accounts, VAT records and bank statements obtained through court-ordered disclosure, supporting a paulian action (action paulienne / Pauliaanse vordering) under Article 5.243 of the new Civil Code to set aside the transfer.

• A creditor holds an ICC arbitral award against a Belgian trading company. The company claims insolvency, but forensic investigation reveals undisclosed real estate held through a Belgian SPRL (société privée à responsabilité limitée / besloten vennootschap, now BV under the Companies and Associations Code). The creditor uses the information order mechanism to compel registry disclosure and then levies enforcement attachment on the property.

• An international joint venture partner suspects misappropriation of funds by the Belgian co-venturer. A court-appointed expert is mandated to audit the joint venture accounts, trace fund flows and identify irregularities. The expert's report forms the basis of both civil damages claims and a criminal complaint for fraud.

Asset tracing in Belgium frequently arises in the context of enforcing a foreign judgment or arbitral award. The procedural pathway differs depending on the origin of the title.

For judgments from EU member states, the Brussels Ia Regulation (Regulation (EU) No 1215/2012) provides a streamlined recognition mechanism. Judgments from other EU courts are recognised automatically and enforceable in Belgium without a separate exequatur procedure for most civil and commercial matters. The creditor files a declaration of enforceability with the enforcement judge, and enforcement can proceed within a short period - typically a few weeks - unless the debtor raises grounds for refusal under Article 45 of the Regulation.

For judgments from non-EU states, Belgium applies the rules of the Code of Private International Law (Code de droit international privé / Wetboek van internationaal privaatrecht), specifically Articles 22 to 25. The Belgian court reviews whether the foreign judgment meets conditions of finality, compatibility with Belgian public policy, absence of fraud and compliance with the rights of defence. This review does not involve a re-examination of the merits, but it does require a formal exequatur proceeding before the court of first instance (tribunal de première instance / rechtbank van eerste aanleg). The process typically takes several months.

For arbitral awards, Belgium is a party to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards. Recognition is sought through an exequatur application to the court of first instance. Belgian courts apply the Convention's grounds for refusal narrowly and have a generally pro-enforcement stance. The process from application to enforceable title typically takes two to four months in straightforward cases.

A common mistake is initiating asset tracing before the enforcement title is secured. While conservatory attachment can be obtained on the basis of a pending claim, enforcement attachment - which allows actual recovery of assets - requires an enforceable title. A creditor who freezes assets but then delays the exequatur process risks having the conservatory attachment lapse or being ordered to pay damages to the debtor if the claim ultimately fails.

The business economics of enforcement in Belgium are worth considering carefully. For a claim in the mid-six-figure EUR range, the combined cost of exequatur proceedings, conservatory attachment and enforcement typically falls in the range of tens of thousands of EUR in legal fees, with court costs adding a further but smaller amount. The procedural burden is significant but manageable for claims of sufficient size. For smaller claims, the cost-benefit analysis may favour alternative dispute resolution or negotiated settlement over full enforcement proceedings.

When a debtor is insolvent or approaching insolvency, asset tracing intersects with insolvency law in ways that significantly expand the creditor's toolkit - and the complexity of the proceedings.

Belgian insolvency is governed primarily by Book XX of the Code of Economic Law (Livre XX du Code de droit économique / Boek XX van het Wetboek van economisch recht), which entered into force in 2018 and was amended to implement the EU Directive on Restructuring and Insolvency (Directive (EU) 2019/1023). The insolvency administrator (curateur / curator) appointed by the enterprise court has broad powers to investigate the debtor's pre-insolvency transactions, compel disclosure from banks and third parties, and bring avoidance actions.

The paulian action (action paulienne / Pauliaanse vordering) under Article 5.243 of the new Civil Code allows a creditor to challenge transactions made by the debtor that were intended to defraud creditors. The creditor must demonstrate that the transaction was made with fraudulent intent, that the debtor's estate was impoverished as a result, and that the counterparty to the transaction was aware of the fraud (in the case of onerous transactions). The action is available both inside and outside insolvency proceedings.

Belgian insolvency law also provides for specific avoidance periods (périodes suspectes / verdachte periodes). Certain transactions made within six months before the declaration of insolvency - or, in the case of gratuitous transactions, within one year - are presumed fraudulent and can be set aside without proof of subjective intent. These provisions, set out in Articles XX.111 and XX.112 of the Code of Economic Law, are powerful tools for recovering assets transferred shortly before insolvency.

Many underappreciate the role of the enterprise court's president in urgent pre-insolvency situations. Under Article XX.32 of the Code of Economic Law, the president may appoint a judicial administrator (administrateur provisoire / voorlopig bewindvoerder) on an urgent basis to protect the assets of a company in difficulty. This mechanism can be used by a creditor who has evidence that the debtor's management is dissipating assets, even before formal insolvency proceedings are opened.

A non-obvious risk in insolvency-adjacent asset tracing is the automatic stay (sursis / opschorting) that applies once insolvency proceedings are opened. Individual enforcement actions by creditors are suspended, and all recovery efforts must be channelled through the insolvency administrator. A creditor who has obtained a conservatory attachment shortly before insolvency is opened may find that the attachment is challenged as a preference, particularly if it was obtained within the suspect period.

The loss caused by an incorrect strategy at this stage can be substantial. A creditor who pursues individual enforcement while insolvency proceedings are imminent may spend significant resources on attachment proceedings that are subsequently set aside, while losing priority to other creditors who filed claims correctly in the insolvency.

What is the most significant practical risk when tracing assets in Belgium without local legal counsel?

The primary risk is procedural error at the attachment stage. Belgian conservatory attachment requires precise compliance with the Judicial Code's formalities - incorrect service, failure to initiate substantive proceedings within the required period after attachment, or attachment of assets that are legally exempt can result in the attachment being lifted and the creditor being liable for the debtor's costs and damages. Foreign creditors unfamiliar with Belgian procedure frequently underestimate the speed at which the debtor can challenge an attachment before the enforcement judge. A successful challenge can unwind weeks of preparatory work and alert the debtor to move assets before a second attempt is made.

How long does the full asset tracing and enforcement process typically take in Belgium, and what does it cost?

The timeline depends heavily on whether the creditor already holds an enforceable title. If a Brussels Ia judgment is available, enforcement attachment can follow within weeks of filing the declaration of enforceability. For non-EU judgments or arbitral awards, the exequatur process adds two to four months. Contested enforcement proceedings, including challenges by the debtor and third-party oppositions, can extend the timeline to twelve months or more. Legal fees for the full process - from forensic investigation through to actual recovery - typically start from the low tens of thousands of EUR for straightforward matters and rise significantly for complex, multi-party or cross-border cases. Court fees and enforcement costs add further amounts that vary with the value of the assets.

When should a creditor consider a criminal complaint as part of an asset tracing strategy in Belgium?

A criminal complaint for fraud, embezzlement or money laundering can be a useful complement to civil proceedings in specific circumstances: where the debtor's conduct appears to involve deliberate concealment, where assets have been moved through multiple jurisdictions, or where the creditor needs access to banking information that cannot be obtained through civil disclosure mechanisms. The Belgian Public Prosecutor has powers to compel bank disclosure and freeze assets that go beyond what is available in civil proceedings. However, a criminal complaint is not a substitute for civil enforcement - criminal proceedings move slowly, the creditor has limited control over the investigation, and the outcome does not directly produce a civil recovery. The most effective strategies use criminal and civil tracks in parallel, with careful coordination to avoid evidentiary conflicts.

Asset tracing, account search and forensic investigation in Belgium form a coherent but technically demanding system. The Judicial Code provides creditors with powerful tools - conservatory attachment, compelled disclosure, court-appointed experts and paulian actions - but each tool has precise conditions, deadlines and risks that require specialist navigation. Foreign creditors who underestimate the procedural complexity or delay action risk losing both assets and priority. A well-structured strategy begins with forensic intelligence, moves quickly to conservatory measures, and coordinates civil and, where appropriate, criminal tracks from the outset.
