Ship Arrests, Arbitration and Enforcement in Greece (2026): Practical Guide for Owners, Charterers & P&I Clubs

Greece remains one of the world’s most strategically important jurisdictions for maritime emergency remedies, and the landscape for ship arrest and arbitration in Greece 2026 has shifted materially since the enactment of Law 5016/2023. That legislation broadened the scope of arbitrability, modernised annulment grounds and strengthened enforcement pathways for both domestic and foreign awards, changes that directly affect how owners, charterers and P&I clubs approach vessel arrests, interim injunctions and post-award execution against Greek-located assets. This guide delivers a step-by-step practical framework: from filing an arrest application in Piraeus through to enforcing an LMAA or ICC award against a ship, bunker stock or bank account, with checklists, timelines and tactical advice calibrated for the post-5016 regime.

Executive Summary: What This Guide Covers and Quick Decision Framework

This article is designed for three audiences operating under time pressure: claimants seeking to arrest a ship or secure assets in Greece, owners and operators defending against or pre-empting arrest, and P&I clubs and insurers managing security, counter-security and enforcement risk. Each section provides both a tactical summary for rapid decision-making and deeper legal analysis for counsel.

The core decision tree for any party confronting a maritime dispute with a Greek nexus runs as follows:

• Immediate asset security needed? Apply ex parte for ship arrest through the Piraeus Single-Member First Instance Court (or the competent port court), orders can be obtained within 24–72 hours in urgent cases.
• Preserving evidence or freezing accounts? Seek interim measures (injunctive relief) from the Greek courts, even where the substantive dispute is subject to foreign-seated arbitration.
• Enforcing an existing award? Pursue recognition and enforcement under the New York Convention (foreign awards) or directly under the Greek Code of Civil Procedure (domestic awards), then execute against the vessel, cargo or bank accounts.

The sections that follow map each of these pathways in detail, with particular attention to the practical changes introduced by Law 5016/2023.

Legal Framework: Law 5016/2023 and How It Changed Ship Arrest and Arbitration in Greece

Key Provisions of Law 5016/2023

Law 5016/2023, which entered into force in September 2023, replaced the previous arbitration provisions of the Greek Code of Civil Procedure (Articles 867–903) with a modern, UNCITRAL Model Law-aligned framework. Industry observers consider it the most significant reform to Greek arbitration law in decades. Its principal effects for shipping practitioners are:

• Broadened arbitrability. The law establishes a presumption that disputes are arbitrable wherever parties have agreed to arbitrate, unless a specific statutory provision expressly prohibits arbitration for that category of claim. This widens the range of maritime disputes, including those involving subcontractors, agents and bunker suppliers, that can be validly referred to arbitration and, critically, that can ground an arrest application.
• Modernised annulment grounds. Annulment of domestic awards is now governed by a closed, exhaustive list aligned with Article 34 of the UNCITRAL Model Law. The practical effect is to reduce the scope for tactical annulment challenges, giving successful claimants greater confidence in enforcement.
• Enhanced interim-measure powers. Greek courts retain full jurisdiction to grant interim measures, including ship arrest, in support of arbitration, whether the seat is in Greece or abroad. The law confirms that a valid arbitration agreement does not deprive Greek courts of the power to order provisional measures.
• International arbitration chapter. Law 5016/2023 introduces a dedicated chapter for international arbitrations seated in Greece, drawing on the UNCITRAL Model Law and addressing recognition of foreign arbitral awards under the New York Convention.

Interaction with the Code of Civil Procedure and the 1952 Arrest Convention

Ship arrest in Greece continues to be governed by the provisional-measures provisions of the Greek Code of Civil Procedure (principally Articles 682–703 on interim measures, and Articles 903–906 as renumbered post-5016 for enforcement of arbitral awards), read alongside the International Convention Relating to the Arrest of Sea-Going Ships (1952), to which Greece is a signatory. The 1952 Arrest Convention defines the categories of “maritime claim” that can ground an arrest and limits arrest to vessels connected to the claim (the “offending ship” or a sister ship in the same beneficial ownership).

Practical Implications for Shipping Claims

For owners, charterers and P&I clubs, the combined effect of Law 5016/2023 and the existing procedural framework is that Greece is now a jurisdiction where:

• Arrest applications can be brought to secure claims subject to foreign-seated arbitration (LMAA, ICC, SIAC or ad hoc) without any jurisdictional objection based on the arbitration clause.
• Enforcement of both domestic and foreign awards is procedurally streamlined, with narrower grounds for challenge.
• Interim measures from Greek courts and emergency arbitrator relief can operate in parallel, giving claimants layered protection.

Arrests in Greece: Statutory Basis, Eligible Claims and Limitations

Who May Arrest a Ship in Greece

Any creditor holding a maritime claim as defined by the 1952 Arrest Convention may apply to arrest a ship in Greece. This includes shipowners (in counterclaim scenarios), charterers, cargo interests, bunker suppliers, salvors, crew members with unpaid wages, and collision claimants. The applicant need not be domiciled or incorporated in Greece, the sole jurisdictional hook is the physical presence of the vessel in Greek waters.

Claims Typically Arrestable

The 1952 Convention enumerates the maritime claims that can support an arrest. The table below summarises the most commonly encountered claim types in Greek arrest practice, together with arrestability status and typical evidentiary requirements:

Limitations and Restrictions

Arrest is not available for every conceivable claim. The 1952 Convention limits arrest to the enumerated categories of maritime claim, and Greek courts apply this list strictly. Disputes arising from ship sale and purchase agreements, for example, generally fall outside the Convention’s scope and cannot support an arrest. Additionally, a claimant must demonstrate a prima facie case, Greek courts will not grant arrest on speculative or unsubstantiated claims. Where the vessel is owned by a party different from the debtor, the claimant must establish beneficial ownership or sister-ship status.

Piraeus Ship Arrest Procedure: Practical Step-by-Step Checklist

Pre-Filing Evidence Checklist

Speed is critical in any arrest. Before instructing local counsel in Piraeus, the claimant (or its P&I correspondent) should assemble the following documents:

• Vessel identification. IMO number, flag, registered owner, manager and P&I club details (obtainable from Equasis or Lloyd’s List Intelligence).
• Ownership / beneficial ownership evidence. Company search extracts, fleet lists, common-director evidence for sister-ship arrests.
• Underlying claim documentation. Charterparty, bill of lading, bunker delivery note, salvage agreement, collision protest, whichever instrument grounds the maritime claim.
• Quantum evidence. Invoices, survey reports, freight statements, repair estimates, sufficient to establish a prima facie value for the claim.
• Correspondence evidencing the dispute. Demand letters, without-prejudice exchanges (redacted as appropriate), default notices.
• Arbitration clause / jurisdiction agreement. To demonstrate that the substantive dispute is (or will be) subject to arbitration, and that the arrest is sought as a provisional measure in support of arbitration.
• Translations. Key documents must be accompanied by certified Greek translations for filing with the court.

Court Filing: Documents, Translation and Local Counsel

The arrest application is filed before the Single-Member First Instance Court at the port where the vessel is located, in the majority of cases, the Piraeus First Instance Court. The application is made ex parte (without notice to the shipowner), supported by a sworn affidavit setting out the facts, the maritime claim, the legal basis for arrest and the evidence relied upon. All supporting documents must be filed in certified Greek translation. Local Greek counsel must sign and file the application, foreign lawyers cannot appear before the Greek court.

A sample structure for the arrest affidavit typically covers:

• Identity of the applicant and its interest in the claim.
• Identity of the vessel, her registered owner and (where relevant) beneficial owner.
• Nature and basis of the maritime claim, with reference to the applicable Convention article.
• Summary of the evidence demonstrating a prima facie case.
• Statement of urgency and risk of the vessel departing Greek waters.
• Request for arrest and, where applicable, an offer of security or undertaking in damages.

Hearing, Order and Physical Arrest

The judge reviews the application, typically the same day or the following court day. If satisfied that the applicant holds a prima facie maritime claim and that the claim falls within the Convention categories, the court issues an arrest order. The order is then served on the port authority (Piraeus Port Authority or the relevant harbour master), which physically prevents the vessel from sailing. The vessel’s master and local agents are notified. In practice, the port authority enforces the arrest by refusing clearance for departure.

Typical Timings and Costs for Ship Arrest in Greece

Piraeus ship arrest procedure timings depend on the court’s schedule and the completeness of the claimant’s evidence package. As a practical guide:

• Preparation and filing: 12–24 hours (assuming documents and translations are ready).
• Court review and order: Same day to next court day, typically within 24–48 hours of filing.
• Service on port authority and physical arrest: Within hours of the order being issued.
• Total elapsed time (urgent cases): 24–72 hours from instruction of local counsel to physical arrest of the vessel.

Costs include court filing fees (relatively modest by international standards), local counsel fees, translation costs and, where required, security deposits. The claimant should budget for the possibility that the court may require a counter-undertaking in damages.

Bunker Arrests and Supplier Remedies: Tactical Approach

How Bunker Claims Differ

Bunker arrest in Greece is one of the most frequently litigated arrest categories in Piraeus. Bunker suppliers face particular evidential challenges because the contractual chain often runs through intermediaries (traders or brokers) rather than directly with the vessel’s registered owner. Greek courts require the supplier to demonstrate a clear link between the fuel delivery and the vessel, along with evidence that the registered or beneficial owner is liable, whether through direct contract, agency principles or the doctrine of necessaries.

Practical Evidence for Bunker Arrests

To successfully arrest a ship in Greece on a bunker claim, suppliers should prepare:

• Bunker delivery note (BDN) signed by the vessel’s chief engineer or authorised officer, confirming quantity and quality of fuel received.
• Commercial invoices addressed to the contractual buyer, showing amounts outstanding and credit terms.
• Fuel samples retained at the time of delivery (relevant where quality disputes may arise as a defence).
• Contractual chain documentation, the supply contract, purchase order confirmation and any correspondence establishing that the owner or operator authorised the purchase.
• Credit history and evidence of demand and non-payment.

Practice Tips for Bunker Suppliers

Industry observers note that Piraeus courts are generally receptive to bunker arrest applications where the documentary trail is clear. However, where the contractual counterparty is a trader rather than the owner, the court will scrutinise the evidence of the owner’s liability closely. Suppliers are advised to obtain confirmation of the owner’s or operator’s authority to order bunkers before delivery, and to ensure the BDN is signed by a vessel officer, not merely by the agent.

Interim Measures in Maritime Greece: Injunctions, Freezing Orders and Emergency Arbitrators

Court Injunctive Relief vs Arbitral Emergency Relief

Greek courts offer a full range of interim measures beyond ship arrest, including freezing orders over bank accounts, injunctions preventing disposal of cargo or equipment, and orders for preservation of evidence. These measures are available under Articles 682–703 of the Code of Civil Procedure and can be sought irrespective of whether the underlying dispute is subject to arbitration, a principle expressly confirmed by Law 5016/2023.

In parallel, parties to ICC or other institutional arbitrations may apply for emergency arbitrator relief. The practical advantage of emergency arbitrator orders is speed and confidentiality; the disadvantage is that enforcement of emergency arbitrator decisions in Greece requires a separate application to the Greek courts, which adds time and cost.

When to Seek Domestic Interim Measures

The likely practical effect of the 2023 reforms is that claimants will increasingly seek interim measures from Greek courts as a first step, even where the substantive arbitration is seated in London, Singapore or Paris, because Greek court orders are directly enforceable by port authorities and banks within Greece. This is particularly valuable where the target asset is a vessel calling briefly at a Greek port.

Practical Interactions with LMAA and ICC Arbitration

Where a dispute is subject to LMAA or ICC arbitration, Greek courts will grant interim measures in support of the arbitration without treating the application as an assertion of jurisdiction over the merits. The claimant should include the arbitration clause in the arrest or injunction application and make clear that the measures are sought on a provisional basis pending the arbitral proceedings. Early indications suggest that Greek courts have adopted a facilitative approach to such applications since Law 5016/2023 came into force.

Enforcing Arbitration Awards in Greece: Domestic and Foreign Awards Step-by-Step

Enforcement of Domestic Awards

An arbitral award rendered in a Greek-seated arbitration is enforceable as a domestic award under the Greek Code of Civil Procedure. The successful party applies to the Single-Member First Instance Court for a declaration of enforceability. The court’s review is limited to verifying that the award is final, that the arbitration agreement was valid and that no ground for annulment exists under the exhaustive list in Law 5016/2023 (mirroring UNCITRAL Model Law Article 34). Once enforceability is declared, the award holder can proceed to execution against the debtor’s assets, vessel, cargo, bank accounts or other property in Greece.

Enforcement of Foreign Awards Under the New York Convention

Greece is a signatory to the 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards. Enforcement of a foreign award (e.g., an LMAA or ICC award rendered in London, Paris or Singapore) follows a two-stage process:

• Stage 1: Recognition application. The award holder files an application with the competent Single-Member First Instance Court, submitting the authenticated original award (or certified copy), the arbitration agreement and certified Greek translations of both documents.
• Stage 2: Enforcement order (exequatur). The court reviews the application against the limited grounds for refusal set out in Article V of the New York Convention (invalidity of agreement, lack of due process, excess of jurisdiction, procedural irregularity, award not yet binding or set aside, public policy). If no ground for refusal is established, the court issues an enforcement order.

Practical Enforcement Against Ships, Bunker Stock and Bank Accounts

Once the enforcement order is obtained, the award holder instructs a bailiff to levy execution against the debtor’s assets in Greece. The most common targets in shipping disputes are the vessel itself (arrest and judicial sale), bunker stock aboard the vessel, freight receivables, and bank accounts held with Greek banks. Enforcement against a vessel involves the same port authority mechanism as a conservatory arrest, but on a definitive (not merely provisional) basis, the vessel can ultimately be sold through a judicial auction.

Timeline and Common Defences

The most commonly raised defences to enforcement of arbitration awards in Greece include: invalidity of the arbitration agreement, breach of due process (failure to give the respondent proper notice of the proceedings), excess of the tribunal’s jurisdiction, and public-policy objections. Post-Law 5016/2023, industry observers expect Greek courts to apply these grounds narrowly, consistent with the pro-enforcement bias of the New York Convention.

Counter-Security, Wrongful Arrest Claims and Risk Management for Owners

Counter-Security Options

An owner or operator whose vessel has been arrested may apply to the court to lift the arrest by providing counter-security, typically a bank guarantee or cash deposit, in an amount sufficient to cover the claimant’s claim, plus interest and costs. P&I club letters of undertaking (LOUs) are widely accepted in Greek practice, provided they are issued in a form and by a club acceptable to the claimant. Where the claimant unreasonably refuses a conforming LOU, the owner can apply to the court for an order lifting the arrest against the security offered.

Claims for Wrongful Arrest

Greek law permits the arrested party to seek damages for wrongful arrest where the arrest was obtained in bad faith or without reasonable grounds. The burden of proof lies with the party alleging wrongful arrest, which must demonstrate that the claimant acted abusively or recklessly. Courts may also require the arresting party to post security at the time of arrest to cover potential wrongful-arrest damages, a factor that claimants must budget for in their arrest strategy.

Best Practice to Reduce Risk

• Assemble robust evidence before filing, do not arrest on speculation.
• Include a realistic quantum assessment; over-claiming weakens credibility and may expose the claimant to wrongful-arrest liability.
• Be prepared to accept a conforming P&I club LOU promptly, unnecessarily maintaining an arrest erodes commercial goodwill and increases exposure.
• Engage experienced local Piraeus counsel with real-time access to port authority and court scheduling.
