How to Obtain a Freezing Order (conservatoir Beslag) in the Netherlands, Step by Step

Prejudgment Attachment in the Netherlands: Securing Assets Before Judgment

Under Dutch law, creditors can take effective measures to secure a debtor’s assets before obtaining a court judgment. One of the most powerful instruments available is prejudgment attachment (conservatoir beslag), which allows creditors to preserve assets and safeguard their prospects of recovery while legal proceedings are pending.

A conservatoir beslag (conservatory or pre-judgment attachment) is one of the most powerful tools available to claimants in the Netherlands because it allows assets to be frozen before any final judgment is obtained, preventing a debtor from dissipating property while a dispute is resolved. This guide sets out, step by step, how the procedure works: the legal thresholds, the evidence you must assemble, the question of security, filing mechanics, enforcement through the bailiff, conversion into enforceable seizure, and the cross-border dimension involving the European Account Preservation Order.

It is written for in-house counsel, creditors, international claimants and litigators who need a practical, English-language overview grounded in primary Dutch and EU sources.

Who this article is for: in-house counsel, creditors, claimants, cross-border litigators and lawyers preparing conservatory attachment applications in the Netherlands. What you will get: a step-by-step checklist, the evidence and documents to prepare, timelines for emergency filings, security options, enforcement mechanics and cross-border considerations, including the EAPO.

What is conservatoir beslag? Legal basis and types

A conservatoir beslag is a conservatory attachment: a protective, pre-judgment measure that freezes a debtor’s assets to safeguard a claimant’s ability to recover a debt or enforce a claim once a judgment or arbitral award is obtained. Unlike enforcement seizure, it does not allow the creditor to sell or realise the asset; it simply “locks” the asset in place so it cannot be moved, transferred or dissipated while proceedings continue. This distinguishes it from executoriaal beslag (executorial attachment), which follows an enforceable title and permits actual realisation of the asset.

Statutory basis

Conservatory attachment is governed by the Dutch Code of Civil Procedure (Wetboek van Burgerlijke Rechtsvordering, commonly abbreviated “Rv”). The Code sets out the rules for applying to the court for leave to levy attachment, the forms of attachment available, the requirement to commence substantive proceedings within a set period, and the role of the bailiff in execution. Because the procedure is codified, an application that follows the statutory framework carefully is more likely to succeed and to withstand a later challenge. Alongside the statutory provisions, the Dutch judiciary publishes national guidelines on conservatory attachment (the beslagsyllabus), which practitioners consult when preparing applications.

Types of assets that can be frozen

The flexibility of Dutch conservatory attachment is one of its key strengths. Depending on the circumstances, a claimant may seek to freeze a wide range of assets:

• Bank accounts. Attachment under a third party (the bank) freezes credit balances held for the debtor.
• Movable property. Goods, inventory, vehicles and equipment can be attached and, where appropriate, placed under judicial custody.
• Claims and receivables. Sums owed to the debtor by third parties (for example, trade debtors) can be attached in the hands of those third parties.
• Shares and securities. Shareholdings and registered securities may be frozen to prevent transfer.
• Immovable property. Real estate can be attached and the attachment registered against the title.
• Intellectual property. Registered IP rights with economic value may also be the subject of attachment.

The breadth of available targets means that a well-advised creditor can often freeze whatever assets are most likely to satisfy the eventual claim, provided the application is properly evidenced.

Legal thresholds and grounds to obtain freezing order conservatoir beslag netherlands protection

To obtain freezing order conservatoir beslag netherlands relief, a claimant must satisfy the court that there is a genuine claim worth protecting. The threshold is deliberately lower than that for a full trial, because the measure is interim and the merits will be determined in substantive proceedings. Nevertheless, the court will apply a proportionality assessment to ensure the measure is not abused.

Plausibility of the claim

The first requirement is that the claimant demonstrates a summierlijk, summary or prima facie, plausible claim. The court does not conduct a mini-trial; it undertakes a preliminary assessment of whether the claim, as presented, appears sound. This means your application must clearly describe the legal and factual basis of the claim: the contract, invoice, loan agreement, tort or statutory right on which you rely, and the amount or value at stake. The clearer and better documented the claim, the more comfortable the court will be in granting leave.

Risk of dissipation and proportionality

Dutch courts take a pragmatic approach to the risk that, without the attachment, enforcement of a future judgment will be frustrated or made significantly more difficult. In practice the risk of asset dissipation does not need to be proven to a high standard, but a claimant who can point to concrete indicators, a debtor relocating assets abroad, selling property, winding down operations, a poor payment history or evasive conduct, strengthens the application. Proportionality matters too: the value of the assets to be frozen should bear a reasonable relationship to the size of the claim, including interest and costs. Over-reaching applications risk being refused or later lifted, and may expose the claimant to a damages claim.

Evidence and documents checklist

Preparation is everything. Because leave for a conservatory attachment is frequently granted on the papers, often without hearing the debtor, the quality of your written application and exhibits is decisive. Below is a practical checklist of the material you should assemble before approaching the court.

Mandatory documents for the court

• The application (verzoekschrift). A written petition to the provisional relief judge (voorzieningenrechter) requesting leave to levy attachment, identifying the creditor, the debtor, the nature and amount of the claim, the assets to be attached and the grounds relied upon. The petition must be filed by a lawyer admitted to the Dutch Bar.
• Evidence of the underlying claim. The contract, invoices, correspondence, loan documentation, delivery notes, statements of account or other documents that establish the debt or obligation.
• Details of the debtor’s assets. Bank details (IBAN where available), the identity of the bank or garnishee, property registration data, share register extracts or inventory lists, the more specific, the more effective the attachment.
• Supporting statement. A clear statement setting out the factual background, the amount claimed and the circumstances giving rise to the perceived risk.
• Translations. Where supporting documents are in a foreign language, Dutch translations may be required or expected, particularly for key contractual documents.

Evidence to prove risk

Beyond proving the claim itself, you should marshal evidence that demonstrates why attachment is appropriate. This may include correspondence showing the debtor refusing or delaying payment, evidence of asset transfers or restructuring, media reports of financial difficulty, credit information, or any communication suggesting the debtor intends to put assets beyond reach. Even where Dutch courts do not demand strict proof of dissipation, a coherent risk narrative supported by exhibits improves the prospects of obtaining, and keeping, the order.

As a working timeline, allow several days to a week to assemble a robust application in a non-urgent matter, though genuinely urgent applications can be prepared and filed far more quickly where the core documents are already in hand.

Security (zekerheid) and counter-security requirements

Because a conservatory attachment interferes with a debtor’s property before any finding on the merits, Dutch courts may require the applicant to provide security to cover potential damages if the attachment later proves to have been wrongful or unjustified. This protects the debtor against the consequences of an attachment that is subsequently lifted or defeated at trial.

Amount and form of security

Where security is required, it is commonly provided in the form of a bank guarantee or a cash deposit. The amount is set at the court’s discretion, having regard to the value of the attached assets and the potential loss the debtor might suffer. In cross-border cases, where an applicant has no assets within the jurisdiction, the court may be more inclined to require security to ensure that any damages award would be collectable.

Alternatives and tactical considerations

Not every application attracts a security requirement; in many domestic cases leave is granted without it. Where security is likely to be ordered, a well-advised applicant proposes an acceptable form proactively, for example, offering a bank guarantee in the application itself, to avoid delay and to signal good faith. Claimants should factor the cost and availability of a guarantee into their overall strategy, as the inability to provide required security can be fatal to the attachment. Conversely, a debtor who wishes the attachment lifted can often achieve this by providing counter-security for the claim, replacing the frozen asset with a guarantee that satisfies the creditor’s protective interest.

How to apply, step-by-step procedural guide

The procedure to obtain freezing order conservatoir beslag netherlands protection follows a defined sequence. Understanding each step helps you file correctly and avoid the technical errors that can delay or defeat an application.

Ex parte procedure and requirements

A distinctive and valuable feature of Dutch conservatory attachment is that leave is usually sought ex parte, that is, without notifying the debtor in advance. The element of surprise is important: if the debtor learned of the application, assets could be moved before the attachment took effect. The application (verzoekschrift) is submitted by a Dutch lawyer to the provisional relief judge of the competent district court, accompanied by the supporting documents and evidence of the claim and risk. Because the debtor is not generally heard, the court relies on the applicant’s candour, which carries a duty to present the facts fairly and completely.

Decision and the judge’s order

In the ordinary case the provisional relief judge decides on the papers, often within a short time, sometimes the same day or within a day or two of filing. The court may grant leave, refuse it, or impose conditions such as security. The order will typically specify the amount for which attachment is permitted and set a deadline within which the claimant must commence substantive proceedings on the merits (the eis in de hoofdzaak). Missing that deadline causes the attachment to lapse, so diary management is critical.

Serving the order on banks and third parties

Once leave is granted, the attachment is actually levied by a bailiff (gerechtsdeurwaarder), who serves the relevant documents on the debtor and, in the case of third-party attachment, on the garnishee, for example the bank holding the debtor’s accounts or a trade debtor owing money. Service on the third party is what freezes the asset: from that moment the garnishee must not release the relevant assets to the debtor.

A practical filing checklist for the application stage:

• Confirm the competent court and the identity and address of the debtor.
• Draft the verzoekschrift stating parties, claim, amount, assets and grounds.
• Assemble exhibits proving the claim and the risk of dissipation.
• Decide on and, where appropriate, propose the form of security.
• File through a Dutch lawyer with the provisional relief judge.
• On grant, instruct the bailiff immediately to levy and serve.
• Diarise the deadline to commence substantive proceedings.

Enforcement mechanics, the role of the bailiff (gerechtsdeurwaarder) and freezing bank accounts

In the Netherlands the court bailiff (gerechtsdeurwaarder) is the officer responsible for executing freezing orders and seizures. The bailiff is a public official whose involvement is required for levying attachment and later for enforcement, and whose role and powers are explained in official government guidance.

Steps the bailiff will take

Upon instruction, the bailiff prepares and serves the attachment documents. For a bank account attachment, the bailiff serves the garnishment on the relevant bank; specific account details or IBAN information make this faster and more targeted, though attachment can be served on a bank by name. For movable property, the bailiff attends to attach and, where necessary, take custody of the goods, drawing up an official record. For immovable property and shares, the attachment is registered in the appropriate registers. The bailiff also effects service of the leave and the required follow-up documents on the debtor.

Typical timeline for banks to act

After the garnishment is served, the bank is obliged to freeze the relevant balances and, in due course, to make a declaration (verklaring derdenbeslag) of what it holds for the debtor. In practice banks act promptly once served, because they risk liability if they wrongly release attached funds. The practical effect is that from the moment of service the debtor cannot access the frozen balance, giving the creditor real leverage while the substantive dispute proceeds.

From conservatoir to executoriaal beslag, converting into enforcement

A conservatory attachment is protective only; it does not by itself allow the creditor to be paid. To realise the frozen asset, the creditor must obtain an enforceable title (executoriale titel), most commonly a court judgment or an arbitral award declared enforceable, and then the conservatory attachment converts into executorial attachment (executoriaal beslag).

The advantage of the conservatory attachment is that it preserves the creditor’s position from the earlier date: once the creditor holds an enforceable title that has been served on the debtor, the existing conservatory attachment transforms into enforcement seizure, generally without the need to levy afresh, provided the statutory steps and deadlines have been observed. This continuity is why early conservatory attachment is so valuable, it secures the asset throughout the litigation and then flows into enforcement.

A conversion checklist for creditors:

• Ensure substantive proceedings were commenced within the court-imposed deadline so the conservatory attachment remains valid.
• Obtain judgment or an enforceable title on the merits.
• Serve the enforceable title on the debtor through the bailiff.
• Instruct the bailiff to proceed to executorial seizure of the already-attached assets.
• Proceed to realisation (for example, sale of movables or payment out of attached account balances) in accordance with the Code.

Cross-border issues, EAPO and recognition of foreign measures

Where a debtor holds bank accounts in more than one EU Member State, or where a creditor is pursuing cross-border recovery, the European Account Preservation Order can complement or substitute for a national conservatory attachment. The EAPO is established by Regulation (EU) No 655/2014 and provides a uniform European procedure for freezing funds held in bank accounts across participating Member States, obtained from one court but effective in the other participating States. Note that Denmark does not participate in the EAPO Regulation.

Separately, the recognition and enforcement of judgments between EU Member States is governed by Regulation (EU) No 1215/2012 (the Brussels I Recast). This instrument allows a judgment given in one Member State to be recognised and enforced in another without the need for a declaration of enforceability, which is central to any strategy that begins with asset preservation in the Netherlands and ends with enforcement elsewhere, or vice versa.

When to use EAPO versus national attachment

National conservatoir beslag remains the natural choice where the targeted assets, bank accounts, movables, real estate, shares or receivables, are located in the Netherlands, because it covers the full range of asset types and plugs directly into Dutch enforcement. The EAPO is typically most attractive where the specific objective is to freeze bank accounts located in other participating EU Member States, allowing a single, coordinated freezing measure across borders. Many cross-border strategies combine the two: national attachment for Dutch assets and EAPO or Brussels I recognition for assets abroad.

Limits, defences and how to challenge or lift an order

A conservatory attachment is not immune from challenge. The law balances the creditor’s protective interest against the debtor’s right not to suffer an unjustified freeze.

Opposition procedure

A debtor may apply to the provisional relief judge to lift the attachment (opheffingskortgeding), typically arguing that the claim is not plausible, that the attachment is disproportionate or unnecessary, that no genuine risk of dissipation exists, or that adequate alternative security has been offered. The court weighs the competing interests summarily and may lift, maintain or modify the attachment, or order the creditor to provide security.

Damages and liability

If an attachment is later shown to have been wrongful, for example because the underlying claim fails or the attachment was disproportionate, the creditor can be liable in damages for the loss the debtor suffered as a result of the freeze. Under established Dutch case law, a creditor who levies attachment does so at its own risk. This potential liability underlines the importance of proportionality, candour in the ex parte application and careful assessment before levying attachment. It is also a key reason why courts may require security from the applicant at the outset.

Practical checklist and templates

Use this quick-reference checklist when preparing to obtain freezing order conservatoir beslag netherlands protection:

• Before filing: confirm competent court, identify debtor and assets, gather claim evidence and risk evidence, decide form of security.
• Drafting the verzoekschrift: state parties, legal and factual basis of claim, amount (with interest and costs), assets to be attached, grounds, and any proposed security.
• Supporting statement headings: background to the relationship; the obligation and its breach; quantum; evidence of risk; relief sought.
• On grant: instruct bailiff immediately; serve garnishees and debtor; keep proof of service.
• After levy: commence substantive proceedings within the deadline; monitor garnishee declarations; prepare for conversion on judgment.
• Throughout: maintain proportionality, document decisions, and reassess if circumstances change.

How to integrate a freezing order into an early dispute resolution strategy

A freezing order is not only a defensive tool; it is a strategic one. Securing a debtor’s assets early can change the negotiating dynamic, because a counterparty whose bank account or property is frozen has a strong incentive to engage constructively. Used proportionately, a conservatory attachment can bring a reluctant debtor to the table and accelerate settlement, mediation or other alternative dispute resolution.

The decision to attach should be weighed carefully against the costs, including any security and potential damages exposure, and against the commercial relationship. In some cases, the prospect of attachment, communicated appropriately, achieves the objective without the need to levy. In others, early attachment is essential to preserve any prospect of recovery. The optimal approach integrates asset preservation into the overall dispute strategy from the outset, so that litigation, negotiation and enforcement planning move together rather than sequentially. Early advice from a qualified Dutch commercial disputes lawyer is invaluable in calibrating this balance.

Key takeaways and recommended next steps

To obtain freezing order conservatoir beslag netherlands protection effectively, a creditor should act quickly, document the claim and the risk of dissipation thoroughly, be ready to provide security where required, and instruct a bailiff to levy promptly once leave is granted. Remember that the attachment is protective only until converted into executorial seizure after an enforceable title is obtained, and that cross-border cases may call for the EAPO or recognition under the Brussels I Recast. The most critical actions are: prepare a strong ex parte application, respect the deadline to commence substantive proceedings, and maintain proportionality throughout. For case-specific advice, consult a qualified Dutch commercial disputes practitioner before filing.
