Pre-judgment Attachments in the Netherlands 2026: How to Obtain, Maintain and Lift Conservatory Beslag

Last updated: 12 August 2026

Quick Answer

Pre-judgment attachments in the Netherlands, known as conservatoir beslag, allow a creditor to freeze a debtor’s assets before obtaining a final court judgment. The statutory mechanism is Article 700 of the Dutch Code of Civil Procedure (Wetboek van Burgerlijke Rechtsvordering, or “Rv”), which empowers the preliminary relief judge (voorzieningenrechter) to grant leave for attachment on the basis of a plausible claim and a demonstrable risk that the debtor will dissipate assets. With 2026 court-fee adjustments now in effect, understanding the updated cost structure is essential for creditors planning asset-security strategies.

In practice, a well-prepared petition can result in an attachment order within days, sometimes within 24 hours in urgent cases. However, the remedy is not without risk: a debtor may challenge the attachment immediately, and a creditor who attaches without adequate justification faces potential liability for damages. This guide walks through the complete process, from statutory requirements and evidentiary thresholds to practical enforcement steps, 2026 costs and lifting routes.

What Is a Conservatory Attachment in the Netherlands, Legal Basis

A conservatory attachment (conservatoir beslag) is a provisional measure that prevents a debtor from disposing of specific assets while litigation is pending or being prepared. It is fundamentally different from an executory attachment (executoriaal beslag), which can only be levied after a creditor has obtained an enforceable title such as a final judgment or arbitral award. The conservatory variant requires no enforceable title, only leave from the court.

The statutory framework sits in Articles 700–770 Rv. Article 700 Rv provides the gateway: a creditor petitions the voorzieningenrechter at the competent district court (rechtbank) for leave to levy a conservatory attachment. The petition is heard ex parte, meaning the debtor is not notified in advance. If granted, the court order specifies the assets to be attached, the maximum claim amount (including an uplift for estimated interest and costs), and the period within which the creditor must commence main proceedings on the merits.

The voorzieningenrechter acts as a gatekeeper. The judge assesses the petition on paper, without oral argument in most cases, and can issue a decision the same day the petition is filed. This speed is one of the defining advantages of the Dutch conservatory attachment system.

Key Statutory Tests: Plausibility, Risk and Urgency

Under Article 700 Rv, the court applies three core criteria. First, the creditor must demonstrate a plausible claim (summierlijk), the standard is not full proof, but the claim must be prima facie credible. Second, there must be a well-founded fear that the debtor will frustrate enforcement by hiding, transferring or encumbering assets. Third, the attachment must be proportionate to the claim. The court retains discretion to refuse leave, impose conditions, or require the creditor to post security.

Grounds and Evidentiary Standard for Pre-Judgment Attachments in the Netherlands

The evidentiary threshold for conservatory beslag is deliberately low. The voorzieningenrechter does not conduct a full trial on the merits; rather, the judge reviews the petition and supporting documents to satisfy the plausibility standard. Industry observers note that Dutch courts grant the vast majority of well-drafted attachment petitions, early indications from recent case law suggest the emphasis has shifted toward proportionality review rather than outright refusal.

Creditors typically support their petition with contracts, invoices, correspondence demonstrating the dispute, sworn statements (verklaringen), corporate registry extracts and evidence identifying the target assets. Where the debtor is a company, a Chamber of Commerce (Kamer van Koophandel) extract and financial statements may be attached. For bank-account garnishment, the creditor should identify the bank and, where possible, the IBAN or branch details.

Financial Claims vs Non-Monetary Claims

For financial (monetary) claims, the court requires the creditor to state the claimed amount and an estimated uplift, typically 30%, to cover interest and costs. Non-monetary claims (for example, delivery obligations or specific performance) can also form the basis for conservatory attachment, but the petition must explain how the attachment secures enforcement of the specific obligation sought.

When Security Is Required by the Court

The voorzieningenrechter may condition the attachment order on the creditor posting a bank guarantee or depositing funds into an escrow account. This typically arises where the court considers the claim less certain, where the attachment affects a substantial portion of the debtor’s business, or where there is a risk of disproportionate harm. Creditors should be prepared to offer security proactively to strengthen the petition.

Step-by-Step Petition to Obtain a Conservatory Beslag (Article 700 Rv)

Obtaining a conservatory attachment in the Netherlands follows a structured sequence. Below is the step-by-step process from initial due diligence to enforcement by a bailiff (gerechtsdeurwaarder).

1. Pre-filing due diligence. Identify the debtor’s assets: bank accounts (name, bank and IBAN where available), real estate (Land Registry / Kadaster search), movable assets (vehicles, inventory, equipment), receivables owed to the debtor by third parties, shares in companies, and, where relevant, vessels (maritime registry search). This step determines the type and scope of attachment to request.
2. Drafting the Article 700 Rv petition. The petition must set out: the identity of the creditor and debtor, a summary of the underlying claim, the legal basis (contractual, tortious or otherwise), the estimated claim amount including the interest-and-costs uplift, identification of the assets to be attached, and a request for leave to levy conservatory attachment. The petition concludes with a petitum, the specific relief sought.
3. Preparing evidentiary annexes. All supporting documents are filed as numbered exhibits. See the checklist table below.
4. Filing with the voorzieningenrechter. The petition is filed at the district court with jurisdiction, generally the court in whose district the debtor is domiciled or where the assets are located. Filing is typically done electronically or through the court registry. In urgent cases, counsel can request same-day treatment.
5. Court decision. The judge reviews the petition on the papers and issues a written order granting or refusing leave. In straightforward cases, the order may be issued on the day of filing or within one to three business days.
6. Enforcement by bailiff. Once leave is granted, the creditor instructs a gerechtsdeurwaarder to levy the attachment by serving the order on the debtor and, where applicable, on third parties (banks, the Land Registry, or port authorities). The attachment takes immediate effect upon service.

Article 700 Petition Checklist

Sample Petition Relief Clause

A typical petitum in an Article 700 Rv petition reads (in translation):

“The applicant respectfully requests the voorzieningenrechter to grant leave to levy conservatory attachment on [description of assets: all bank accounts held by the respondent at [Bank], and/or all movable assets located at [address]], to secure a claim estimated at EUR [amount], plus an uplift of 30% for interest and costs, and to set a period of [14 days] within which the applicant must commence main proceedings.”

What Assets Can Be Seized, Practical Enforcement Steps

Dutch law permits conservatory attachment on a wide range of assets. The choice of attachment type depends on what the debtor holds and where the assets are located. Below is a practical overview of the most common seizure routes.

To seize a bank account in the Netherlands, the creditor does not need to know the exact account number in every case, identifying the bank where the debtor holds accounts is generally sufficient. Upon service of the attachment order, the bank is legally obligated to freeze the account up to the stated amount and to provide a declaration (derdenverklaring) stating the balance held at the time of attachment.

Attachment Timelines, Dutch Court Fees 2026 and Enforcement Costs

Speed is a hallmark of the Dutch conservatory attachment procedure. However, realistic timelines vary depending on court workload, case complexity and the type of asset targeted. The following bands reflect current practice.

• Urgent / ex parte petition: Court decision within 1–3 business days; same-day decisions are possible in genuinely urgent cases.
• Standard petition: Court decision within 1–3 weeks where the case is less urgent or the court requests supplementary information.
• Enforcement (bailiff execution): Attachment takes effect immediately upon service of the court order; the bailiff typically executes service within 1–5 business days of receiving the order.
• Main proceedings deadline: The court order sets a term (commonly 14 days) within which the creditor must initiate proceedings on the merits. Failure to do so results in lapse of the attachment.

Dutch Court Fees 2026 (Griffierechten)

Court fees for civil proceedings in the Netherlands are governed by the Wet griffierechten burgerlijke zaken and are updated annually. The 2026 fee regulation sets the following indicative bands for conservatory attachment petitions.

Practitioners should consult the official 2026 fee schedule on wetten.overheid.nl for the precise figures applicable to their petition, as the fee bands are adjusted each calendar year. Total costs for a straightforward attachment, including court fees, bailiff fees and counsel, vary, but creditors should budget for the full range of procedural expenses at the outset.

How to Lift or Challenge a Conservatory Beslag, Lifting a Pre-Judgment Attachment in the Netherlands

A debtor whose assets have been attached is not without recourse. Dutch law provides several avenues to challenge or lift a conservatory beslag, and creditors must be prepared for immediate counter-action.

The primary remedy is a motion to lift the attachment (opheffing van het beslag), brought before the same voorzieningenrechter who granted the original leave. The debtor can file this motion at any time after the attachment is levied. Grounds for lifting include:

• Absence of a plausible claim: The debtor argues that the underlying claim is unfounded or insufficiently substantiated.
• Disproportionality: The attachment is excessive relative to the claim, or it causes unnecessary harm to the debtor’s business operations.
• Adequate security offered: The debtor offers a bank guarantee or other security sufficient to cover the creditor’s claim, rendering the attachment unnecessary.
• Procedural defects: The creditor failed to commence main proceedings within the court-imposed deadline, or the petition contained material misrepresentations.

If the court finds the attachment unjustified or disproportionate, it will order the attachment lifted. The debtor may also claim damages for wrongful attachment, a creditor who levies conservatory beslag does so at its own risk, and is strictly liable for damages if the claim ultimately proves unfounded.

From the creditor’s perspective, the best defence against a lifting motion is to maintain a strong evidentiary record, commence main proceedings promptly, and be prepared to negotiate appropriate security arrangements. Where a debtor offers a bank guarantee covering the full claim plus interest and costs, the likely practical effect will be that the court lifts the attachment on condition that the guarantee remains in place.

Cross-Border Enforcement and EU Recognition of Pre-Judgment Attachments

Where the debtor’s assets are spread across multiple EU Member States, creditors should consider the interplay between Dutch conservatory beslag and EU cross-border enforcement mechanisms. Two instruments are particularly relevant.

First, Regulation (EU) No 1215/2012 (the Brussels I Recast) governs jurisdiction and the recognition and enforcement of judgments in civil and commercial matters across the EU. Under certain conditions, a provisional measure granted by a Dutch court can be recognised and enforced in another Member State, although restrictions apply, measures granted without the defendant having been summoned to appear may face limitations on recognition.

Second, the European Account Preservation Order (EAPO), established by Regulation (EU) No 655/2014, provides a dedicated EU-wide mechanism for freezing bank accounts in cross-border cases. The EAPO can be obtained from a Dutch court (or the court with jurisdiction over the main proceedings) and is directly enforceable in the Member State where the bank account is held, without the need for an exequatur procedure.

Industry observers expect the EAPO to become increasingly popular for cross-border debt recovery, particularly where the debtor holds accounts in multiple jurisdictions. However, the Dutch conservatory beslag remains the preferred route for domestic assets and for asset types not covered by the EAPO (such as real estate, movables, shares and vessels).

Risks, Sanctions and Debtor Defenses

Creditors should weigh several risks before pursuing conservatory attachment:

• Strict liability for wrongful attachment. If the underlying claim is ultimately dismissed, the creditor is liable for all damages suffered by the debtor as a result of the attachment, regardless of whether the creditor acted in good faith.
• Proportionality scrutiny. Courts increasingly assess whether the scope of the attachment is proportionate to the claim. Attaching assets far exceeding the claim value invites a successful lifting motion.
• Procedural deadline risk. Failure to commence main proceedings within the court-imposed deadline (typically 14 days) causes the attachment to lapse automatically.
• Reputational and commercial impact. Freezing a trading partner’s bank accounts or arresting a vessel can have significant commercial repercussions. Creditors should consider whether negotiation or mediation may achieve the same result with less collateral damage.

Practical mitigation involves careful pre-filing assessment, precise asset identification, requesting attachment only on assets proportionate to the claim, and maintaining a willingness to accept reasonable security in lieu of continuing the attachment.

Conclusion

Pre-judgment attachments in the Netherlands remain one of the most effective provisional remedies available to creditors in the EU. The process is fast, the evidentiary threshold is deliberately accessible, and the range of attachable assets, from bank accounts and receivables to real estate and vessels, is broad. With the 2026 court-fee adjustments now in force, creditors benefit from understanding the updated cost structure alongside the procedural steps required under Article 700 Rv.

Success depends on preparation: thorough asset identification, a well-drafted petition with strong supporting evidence, and a clear strategy for the main proceedings that must follow. Equally, creditors must remain alive to the risks of wrongful attachment and the likelihood that a debtor will move quickly to challenge the order.
