Vessel Seizure in the Netherlands (2026): Conservatoir Beslag, Bank Guarantees & How to Lift an Attachment

Last updated: 14 May 2026

A vessel seizure in the Netherlands can happen with almost no warning: a creditor obtains a court order, a bailiff boards the yacht, and within hours the vessel is immobilised at its berth. Under the Dutch conservatoir beslag regime, one of the most creditor-friendly pre-judgment attachment systems in Europe, boats, motor yachts and commercial vessels can all be seized before a court has ruled on the merits of the underlying claim. The 2026 changes to griffierechten (court fees) have raised both the frequency and the cost of these actions, making it essential for yacht owners, marina operators and watersport businesses to understand their rights, obligations and defence options.

This guide provides a step-by-step operational playbook covering the legal framework, enforcement procedures, bank-guarantee alternatives, updated cost implications, and immediate actions to take in the first 24–72 hours after receiving a seizure notice.

Immediate steps (first 24 hours), for owners and marinas:

• Do not move, hide or attempt to sail the vessel.
• Request and photograph the full court order and bailiff identification.
• Notify your insurer and instruct specialised civil litigation counsel immediately.
• Secure all onboard documents, logbooks and personal valuables, document everything with time-stamped photographs.
• Marina operators: restrict access to the berth and log all third-party visits.

What Is Conservatoir Beslag? Can a Yacht Be Seized in the Netherlands?

Under Articles 700–710 of the Dutch Code of Civil Procedure (Wetboek van Burgerlijke Rechtsvordering, commonly abbreviated “Rv”), a creditor may apply for conservatoir beslag, a pre-judgment conservatory attachment, to secure a claim before the court has decided the dispute on its merits. The attachment prevents the debtor from selling, transferring or removing the asset. Dutch law sets a deliberately low threshold for obtaining leave: the applicant need only demonstrate a summarily plausible claim and a justified fear that assets may be dissipated. A court typically grants leave within one to three days, often without hearing the other side (an ex parte procedure).

For the watersport sector, this means a boat seizure in the Netherlands can occur over an unpaid repair invoice, a contractual dispute between co-owners, a financing default, or even a third-party tort claim. Yachts and other vessels qualify as movable property for attachment purposes, and a maritime asset seizure follows the same procedural rules as the attachment of other movable assets, though additional practical complexities arise when vessels are moored in marinas or need to meet safety inspection deadlines. For deeper background on the general conservatoir beslag framework, see our full practice guide on conservatoir beslag, bank guarantees and lifting rules.

Types of Assets That Can Be Attached

Dutch law permits conservatory attachment on a broad range of assets. For vessel owners, the most relevant categories include:

• Movable property (roerende zaken): Yachts, motor boats, sailing vessels and jet skis, including those stored on hardstanding or in dry-dock.
• Registered vessels: Vessels registered in the Dutch Ship Registry (Kadaster, Scheepsregister) may be subject to ship mortgage (scheepshypotheek). Attachment of a registered vessel requires the bailiff to record the attachment in the registry.
• Bank accounts and receivables: A creditor may simultaneously attach the vessel owner’s bank accounts or outstanding receivables from charter contracts.
• Claims against third parties (derdenbeslag): Berthing-fee deposits held by the marina on behalf of the owner can themselves be attached.

Criminal vs Civil Seizure

It is critical to distinguish a civil conservatoir beslag from a criminal seizure. The police or Public Prosecution Service (Openbaar Ministerie) may seize a vessel as evidence of a criminal offence or for the purpose of confiscation under criminal law. In a criminal seizure, the yacht seizure defence options are fundamentally different: the owner must apply to the criminal court rather than the civil voorzieningenrechter (preliminary relief judge). The procedural timelines, evidentiary standards and remedies follow the Dutch Code of Criminal Procedure rather than the Rv. If a vessel has been seized by police, owners should instruct a criminal-law specialist alongside civil litigation counsel.

Who Enforces Vessel Seizures in the Netherlands and What Happens in a Marina?

Vessel enforcement in the Netherlands involves several distinct actors, each operating under different legal authority. Marinas and harbour operators often find themselves caught in the middle, legally obligated to cooperate with a bailiff but commercially motivated to protect the berth-holder relationship. Understanding each entity’s enforcement powers is essential for any marina operator or watersport business managing berthing, storage and maintenance operations.

Practical guidance for marinas: When a bailiff presents a court order, the marina is legally obliged to cooperate. Refusing access or tipping off the vessel owner in advance can expose the marina to liability for obstruction. However, the marina should verify the bailiff’s identity, request a copy of the court order, record the date and time of all actions, and ensure that third-party property stored on or near the vessel is documented separately. If the vessel requires safety-related maintenance during the attachment (such as bilge pumping or de-icing), the marina should seek written confirmation from the bailiff or the creditor’s lawyer before incurring costs.

Step-by-Step: What to Do on Receipt of a Vessel Seizure Notice (Owner & Marina Checklist)

Speed matters. Under the Dutch attachment regime, the creditor is typically required to commence main proceedings (eis in de hoofdzaak) within a period set by the court, commonly 14 days after the attachment is effected. But for the owner, the first 24–72 hours are decisive: evidence gathered and preserved in this window often determines the outcome of a lifting application. The following 12-step checklist covers the critical actions for both vessel owners and marina operators.

Owner checklist:

1. Stay calm and do not attempt to move, hide or sail the vessel.
2. Request the bailiff’s identification and a full copy of the court order (beslagverlof).
3. Photograph the seizure tags, the bailiff’s documents and the current condition of the vessel (deck, hull, engine room, electronics).
4. Note the exact date and time of service, this starts the clock on procedural deadlines.
5. Contact specialised civil litigation counsel immediately, ideally within the first working day.
6. Notify your vessel insurer and your mortgage lender (if applicable).
7. Gather and secure all documents related to the underlying claim: contracts, invoices, correspondence, payment records.
8. Do not communicate directly with the creditor or their lawyer without your own counsel’s guidance.
9. Prepare a written inventory of all personal property onboard (valuables, electronics, safety equipment).
10. If the vessel is chartered or commercially operated, notify charterers and business partners of the operational disruption.
11. Begin assembling evidence for a potential lifting application or bank-guarantee request (see below).
12. Request from your bank an indication of whether a bank guarantee can be issued, and at what cost.

Marina operator checklist:

1. Verify the bailiff’s credentials and obtain a copy of the court order for your records.
2. Restrict physical access to the berth, log all visits by any party.
3. Photograph the vessel’s condition at the time of seizure to protect the marina against later damage claims.
4. Do not release the vessel without confirmation from the bailiff or a court order lifting the attachment.
5. Notify your own insurer and legal counsel if the attachment creates storage, safety or environmental liability risks.

How to Challenge or Lift a Conservatory Attachment on a Vessel

Under Article 705 of the Dutch Code of Civil Procedure (Rv), the court may lift a conservatory attachment if the attachment was unlawfully or unnecessarily laid, or if the debtor provides sufficient alternative security, typically in the form of a bank guarantee. This is the central statutory provision governing the lifting of an attachment on a vessel, and it gives the voorzieningenrechter (preliminary relief judge) broad discretion. The principal grounds for challenging or lifting attachment on a vessel are as follows:

• Summarily implausible claim: If the underlying claim is clearly unfounded, the court may lift the attachment. The debtor must demonstrate that the creditor’s claim does not meet the low threshold of “summarily plausible.”
• Procedural defects: If the creditor failed to comply with formal requirements, for example, failing to commence main proceedings within the court-imposed deadline, the attachment lapses automatically.
• Disproportionality: The court may lift attachment where the value of the seized vessel far exceeds the claimed amount, or where the attachment causes disproportionate harm to the debtor’s business operations.
• Alternative security (bank guarantee): The most common route to lifting attachment on a vessel is for the owner to offer a bank guarantee that replaces the security provided by the attachment itself.
• Jurisdictional challenges: If the Dutch court lacks jurisdiction over the underlying dispute (for instance, where a foreign-court or arbitration clause applies), the attachment may be challenged on jurisdictional grounds.

Bank Guarantee: When Accepted and How to Present

Offering a bank guarantee is the fastest practical route to freeing a seized vessel. According to practice guidance from leading Dutch litigation firms, the bank guarantee must typically satisfy several conditions to be accepted by the court or the attaching creditor:

• The guarantee must be unconditional and payable on first demand, conditional or documentary-credit-style guarantees are usually rejected.
• It must be issued by a reputable Dutch or internationally recognised bank.
• The guaranteed amount must cover the claimed sum plus a margin (typically 30% to cover interest, costs and potential damages).
• The guarantee must remain in force until a final, unappealable judgment on the underlying claim.

Sample bank-guarantee wording (indicative, always verify with counsel):

“[Bank name], having its registered office at [address], hereby irrevocably and unconditionally guarantees to [creditor name] payment on first written demand, without requiring proof or conditions, of any amount up to EUR [amount], in connection with the claim of [creditor] against [debtor] as secured by conservatory attachment laid on [date] on the vessel [name/registration]. This guarantee shall remain in full force until [final judgment / agreed termination event].”

Emergency Court Applications and Evidence Required

Applications to lift conservatoir beslag are heard by the voorzieningenrechter in summary proceedings (kort geding). In practice, a hearing can typically be obtained within a few days to two weeks, depending on the court’s schedule and the urgency demonstrated. The applicant should prepare a petition (dagvaarding in kort geding) setting out the grounds for lifting, supported by documentary evidence including the court order, the underlying contract or invoice, evidence of payment or counterclaim, and, where applicable, the proposed bank guarantee. Expert valuations of the vessel may also be relevant where disproportionality is argued.

Costs and Exposure if You Lose

If the court declines to lift the attachment, the vessel remains seized and the owner bears the legal costs of the failed application. Additionally, if a bank guarantee has been issued and the creditor ultimately prevails on the merits, the guarantee will be called, meaning the bank pays the creditor and recovers from the owner. Owners should budget for the realistic risk that the guarantee amount (claim plus 30% margin) may be drawn down in full. The costs of a failed lifting application, including the court’s cost order, own legal fees and lost operational revenue, can be substantial, particularly for commercially operated vessels.

Bank Guarantee vs Attachment: Comparison and Recommended Approach for Vessel Seizure in the Netherlands

Deciding between tolerating a conservatoir beslag and offering a bank guarantee requires a clear-eyed assessment of cost, speed and operational impact. The following comparison table summarises the key differences for yacht owners, marina operators and creditors.

Recommended decision steps:

• Assess urgency: If the vessel is commercially operated or a sailing season is imminent, the operational cost of continued attachment usually outweighs the bank-guarantee fee.
• Approach your bank early: Guarantee issuance can take several business days. Contact your bank as soon as a seizure threat emerges, ideally before the attachment is laid.
• Negotiate guarantee terms: In some cases, the creditor will accept a guarantee with a lower margin than the standard 30%, especially if the claim is partially disputed.
• Monitor the guarantee call risk: Instruct your lawyer to track the main proceedings closely. If the case settles, ensure the guarantee is formally released by the creditor.

Costs, Griffierechten 2026 and Fee Planning for Seizure Actions

The 2026 amendments to the Dutch court-fee schedule (griffierechten), published by the Dutch government via Rijksoverheid, have adjusted the fee bands for civil proceedings, including applications for conservatory attachment and summary proceedings to lift an attachment. The practical effect for the watersport sector is that both creditors initiating a seizure and owners defending against one now face higher upfront procedural costs. Courts publish the current griffierechten schedule on Rechtspraak.nl; practitioners should verify the exact fee applicable to their claim amount before filing.

The following cost-band table provides indicative ranges for a typical vessel seizure case in 2026. Actual costs will vary depending on claim size, complexity and whether the case proceeds to main proceedings.

Budgeting tip: Marina operators who regularly handle seized vessels should include a seizure-cooperation clause in their berthing contracts, specifying who bears storage, insurance and supervision costs during an attachment. This avoids disputes with both the vessel owner and the creditor over accumulated marina charges. For jurisdictions outside the Netherlands that have recently reformed maritime enforcement costs, see for example the 2026 changes to China’s Maritime Code and the 2026 Malaysia maritime law reforms.

Cross-Border and Complex Cases: Foreign-Flagged Yachts, Mortgages and Sanctions

The Netherlands is a popular destination for foreign-flagged yachts transiting or wintering in Dutch harbours. A conservatoir beslag can be laid on a foreign-flagged vessel present in the Netherlands, regardless of the vessel’s flag state, the physical presence of the yacht within Dutch territorial waters or in a Dutch port is sufficient. However, cross-border cases introduce additional complexity: the enforceability of a Dutch attachment order abroad, the interplay with ship-mortgage registrations in the flag state, and potential conflicts of jurisdiction under the Brussels I Regulation (Recast) or bilateral treaties.

Where a vessel is subject to a registered ship mortgage (scheepshypotheek), the mortgage holder’s rights generally take priority over a subsequent conservatory attachment. The attaching creditor obtains security, but upon enforcement the mortgage holder is paid first from the sale proceeds. Owners with mortgaged vessels should notify their mortgage lender immediately upon seizure.

Special Note: Sanctioned or Arrested Yachts

Since 2022, EU sanctions regulations have led to the freezing of assets, including luxury yachts, belonging to designated persons. A sanctions-related freezing order operates entirely outside the civil conservatoir beslag framework: it is an administrative measure enforced by customs authorities and the Dutch Central Bank (De Nederlandsche Bank). If a vessel has been frozen under EU sanctions, the owner’s remedies lie in administrative law and before the EU General Court, not in the civil courts. Immediate legal escalation to a sanctions-specialist lawyer is essential.

Conclusion: Vessel Seizure in the Netherlands, Immediate Next Steps

A vessel seizure in the Netherlands moves fast and carries significant financial and operational consequences for owners, marinas and watersport businesses alike. The 2026 griffierechten changes have increased the cost stakes for all parties. Whether you are a yacht owner facing an unexpected conservatoir beslag, a marina operator managing a seized vessel on your premises, or a creditor evaluating whether to pursue a maritime asset seizure, the following five-point action card should guide your immediate response:

1. Secure the scene: Photograph everything, request the full court order, and log the bailiff’s details.
2. Instruct specialist counsel: Engage a civil litigation lawyer with experience in conservatoir beslag and nautical law within 24 hours, find a civil litigation lawyer (Netherlands) via our directory.
3. Assess the bank-guarantee route: Contact your bank immediately about issuing an unconditional guarantee on first demand.
4. Preserve evidence: Gather all documents related to the underlying claim and begin preparing for a potential lifting application under Article 705 Rv.
5. Budget realistically: Factor in 2026 court fees, legal costs, marina holding charges and potential guarantee-call exposure when evaluating your options.
