Enforcing Arbitration Awards in Greece (2026): Ship Arrests, Freezing Orders & Recognition

Enforcing arbitral awards in Greece 2026 requires a clear understanding of both the reformed arbitration framework introduced by Law 5016/2023 and the civil-procedure modernisation that has reshaped how Piraeus and Athens courts handle interim relief applications. Shipowners, charterers, P&I clubs and cargo insurers now operate in a legal environment where tribunal-ordered interim measures carry greater weight, yet coercive remedies, ship arrests, bunker arrests, freezing orders, still depend on swift engagement with Greek courts. This guide delivers the practitioner checklists, document lists, tactical matrices and step-by-step enforcement procedures that maritime stakeholders need to protect their positions. It reflects current court practice and draws on the primary legislative texts, the New York Convention and leading jurisdictional commentaries.

Executive summary & practical takeaways

A concise overview of the key actions, timelines and documents practitioners must prepare when enforcing awards or seeking interim relief in Greece.

• Ship arrest remains available during pending arbitration. Greek courts retain jurisdiction to order precautionary ship arrest even where the merits are subject to a domestic or foreign arbitration agreement, provided the claimant demonstrates a prima facie claim and risk of loss.
• Law 5016/2023 expanded tribunal interim powers. Arbitral tribunals seated in Greece can now order interim measures with clearer legal footing, but coercive enforcement (physical arrest, bank freeze) still requires a court order.
• The 2026 civil-procedure reforms accelerate digital filing. Applications for provisional measures, enforcement of awards and related motions can now be filed electronically at Piraeus and Athens courts, reducing processing bottlenecks.
• Foreign awards are enforced under the New York Convention. Greece is a signatory; enforcement requires filing the original award, the arbitration agreement and certified translations before the competent single-member court.
• Freezing orders can be obtained ex parte. Where urgency is established, Greek courts routinely grant provisional bank-account seizures within 24–72 hours, subject to a counter-security bond.
• Bunker arrest follows a distinct evidentiary path. Claimants must prove the maritime lien or in rem claim against the bunkers specifically, with evidence of supply and non-payment.
• Emergency arbitration is not a substitute for court relief where coercion is needed. Use emergency arbitrators for non-coercive orders (preservation of evidence, status-quo obligations) and Greek courts for arrest or attachment.
• Prepare documents in advance. In fast-moving maritime disputes, having a certified power of attorney, translated contract extracts and a sworn affidavit ready can mean the difference between a same-day arrest and a missed vessel.

Legal framework: Law 5016/2023 arbitration reform & civil procedure reform 2026

The two legislative pillars that define enforcing arbitral awards in Greece today, one reforming arbitration law, the other modernising the courts that execute those awards.

Law 5016/2023, core provisions

Law 5016/2023, published in the Government Gazette in 2023, overhauled Greece’s arbitration regime by aligning it more closely with the UNCITRAL Model Law on International Commercial Arbitration. The statute expanded the categories of disputes that are arbitrable, bringing a wider range of shipping and commercial claims firmly within arbitral jurisdiction. Critically for maritime practitioners, the law codified the power of arbitral tribunals to order interim measures, including orders for the preservation of assets, the maintenance of the status quo and evidentiary injunctions.

The law also streamlined the domestic recognition and enforcement procedure for arbitral awards, clarifying the competent court and reducing procedural formalities. Industry observers expect that the practical effect of these changes will be fewer procedural challenges to award enforcement and faster turnarounds at the recognition stage. For a broader exploration of how local courts interact with international arbitration, practitioners should consider the interplay between tribunal and judicial powers under the new framework.

2026 civil-procedure changes, enforcement implications

The 2026 civil-procedure modernisation built on the foundation laid by Law 5016/2023. Its key provisions affecting enforcement and interim relief in the maritime context include:

• Digital filing and service. Applications for provisional measures, including ship-arrest petitions, can now be filed electronically at Piraeus and Athens courts, with digital service of process recognised as valid.
• Streamlined provisional-measures track. A dedicated procedural stream for urgent interim applications reduces scheduling delays, which is particularly beneficial in ship-arrest cases where a vessel’s port call may last only hours.
• Updated enforcement-agent procedures. Post-award execution, including the judicial sale of arrested vessels, follows revised rules on notification, auction procedure and priority of claims, tightening the timeline from judgment to realisation.

International instruments: New York Convention & UNCITRAL Model Law

Greece ratified the 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, which remains the primary vehicle for recognition of foreign awards Greece. Article V of the Convention sets out the exhaustive grounds on which recognition or enforcement may be refused, including invalidity of the arbitration agreement, denial of due process, excess of jurisdiction, irregular tribunal composition and violation of public policy. The UNCITRAL Model Law, as adapted through Law 5016/2023, provides the template for domestic arbitration procedure, including the framework for interim measures that tribunals may order.

Together, these instruments give Greece one of the more arbitration-friendly frameworks in the eastern Mediterranean, a point of particular importance for the shipping community that is headquartered in and around Piraeus. For a comparative view of how Greece ranks among top countries for international arbitration and dispute resolution, GLE’s global guide provides useful context.

Interim measures in Greece: court vs arbitral tribunal

Greek law permits both courts and tribunals to order interim measures, but the type of relief and its enforceability differ significantly.

Tribunal interim relief, scope & enforceability

Under the framework established by Law 5016/2023, an arbitral tribunal seated in Greece can order a range of interim measures: preservation of assets, maintenance of the status quo, orders to refrain from specific conduct, and evidentiary preservation orders. These powers mirror those available under the UNCITRAL Model Law and give tribunals meaningful tools to manage disputes.

However, there is a critical limitation. Tribunal-ordered interim measures lack direct coercive force. An order by an arbitral tribunal cannot, on its own, compel a port authority to detain a vessel, instruct a bank to freeze an account or authorise a bailiff to seize cargo. To give such orders teeth, the successful party must apply to the competent Greek court for conversion into an enforceable court order, a process that, while faster under the 2026 reforms, still requires a separate application.

Court-ordered interim relief, types

Greek courts can grant the following categories of provisional measures relevant to maritime disputes, regardless of whether the underlying dispute is subject to arbitration:

• Ship arrest (precautionary seizure). The most common remedy in shipping disputes, detaining a vessel in Greek waters to secure a maritime claim.
• Bunker arrest. Seizure of bunkers (marine fuel) aboard a vessel, typically to secure claims by bunker suppliers.
• Freezing orders (provisional attachment of bank accounts). Seizure of funds held in Greek bank accounts to prevent dissipation pending arbitration or enforcement.
• Injunctions. Orders restraining a party from specific conduct, for example, prohibiting the transfer of vessel ownership pending resolution of a dispute.

The essential point for practitioners is that interim measures arbitration Greece disputes will almost always require parallel engagement with local courts whenever coercive enforcement is needed.

Tactical matrix: when to choose court vs tribunal

Ship arrests in Greece: step-by-step claimant checklist

A complete practitioner checklist covering jurisdiction, required documents, timelines and costs for arresting a vessel or bunkers in Greek waters.

Arrest for collision, cargo & contractual claims

Ship arrest Greece applications are filed before the single-member First Instance Court of the port where the vessel is located, in the vast majority of cases, the Piraeus First Instance Court. The claimant must establish:

1. A prima facie maritime claim. This includes claims arising from collision, cargo damage, salvage, general average, crew wages, towage, pilotage, supply of necessaries and breach of charterparty or bill of lading.
2. A reasonable apprehension of loss. The claimant must show that there is a risk the claim will go unsatisfied absent the arrest, for example, the vessel is about to leave Greek waters, the owner has no substantial assets in Greece, or there is a pattern of non-payment.
3. Connection between vessel and claim. In most cases, the arrested vessel must be the ship in respect of which the claim arose, or a sister ship owned by the same party.

Applications can be heard ex parte, and experienced Piraeus judges will frequently issue arrest orders the same day or within 24 hours of filing where the documentation is complete and the urgency is clear. The claimant must typically provide counter-security (a bond or bank guarantee) to protect the ship’s interests if the arrest is later found to be unjustified.

Bunker arrest procedure

Bunker arrest Greece claims follow a similar procedural path but involve distinct evidentiary requirements. The bunker supplier must establish the in rem nature of the claim, typically by proving:

• A valid contract for the supply of bunkers (purchase order, confirmation, delivery receipt).
• Delivery of the bunkers to the named vessel (bunker delivery notes, surveyor reports).
• Outstanding payment (invoices, demand letters, bank records showing non-payment).

Where bunkers have been supplied on credit terms common in the industry (30–60 days), the claimant should have the full documentary chain ready before the vessel enters Greek waters. Early indications suggest that following the 2026 reforms, electronic filing of the bunker arrest application and supporting documents has reduced administrative processing time.

Worldwide arrest considerations & transits

Greek court arrest orders are effective only within Greek territorial waters. However, where a vessel is known to be transiting Greek waters, for example, passing through the approaches to Piraeus or transiting the Corinth Canal, practitioners must coordinate arrest timing with local agents and port authorities to ensure service is effected while the vessel is within jurisdiction. For claimants pursuing assets across multiple jurisdictions, Greek arrest can be a powerful first step, establishing leverage for negotiation or settlement while proceedings continue under a foreign arbitration clause.

Sample arrest application checklist

Practitioners should note that having these documents pre-assembled, particularly the power of attorney and certified translations, dramatically increases the likelihood of obtaining a same-day arrest. For guidance on the broader mechanics of preparing for and conducting arbitration hearings, GLE’s overview is a helpful companion resource.

Freezing orders & bank account seizures: evidence standard & tactics

Freezing orders Greece, provisional attachment of bank accounts, require a clear evidentiary threshold and tactical awareness of bonding obligations.

Ex parte freezing orders

A claimant seeking a provisional attachment of bank accounts in Greece must apply to the competent First Instance Court and demonstrate:

1. A probable claim. The threshold is lower than full proof, the court requires a reasonable likelihood of success on the merits.
2. Urgency or imminent risk of dissipation. Evidence that the respondent is moving assets, closing accounts or preparing to leave the jurisdiction strengthens the application materially.
3. Identification of accounts or assets. While not always required at the ex parte stage, specifying the bank, branch and account number where possible accelerates enforcement.

In urgent cases, Greek courts can issue freezing orders within 24–72 hours of application. The applicant will almost always be required to provide counter-security, typically a bank guarantee, to protect the respondent if the freeze is later discharged.

Worldwide freezing vs domestic bank garnishment

Greek court orders can freeze assets held in Greek banks, but they do not have direct extraterritorial effect. A claimant seeking a worldwide freezing order must pursue parallel applications in other jurisdictions. However, the Greek freeze is a powerful domestic tool, particularly given the concentration of shipping company bank accounts in Piraeus and Athens. Where the respondent’s principal banking relationship is in Greece, a domestic freezing order can effectively immobilise the commercial operations of a shipping company, creating strong settlement incentives.

Practical drafting tips

• Identify the specific bank branches in the application, Piraeus judges respond more favourably to well-targeted requests than to blanket seizure applications.
• Include a clear summary of the urgency narrative in the first page of the application, ex parte hearings are fast, and judges need to grasp the risk immediately.
• Prepare the counter-security bond in advance; delays in posting security can delay the order’s issuance.

Enforcing foreign arbitral awards in Greece, recognition procedure

The step-by-step process for recognition of foreign awards Greece under the New York Convention, including documentation, grounds for refusal and timelines.

ICC award enforcement checklist

To enforce an ICC award (or any foreign arbitral award) in Greece, the award-creditor must file an application for recognition and enforcement before the competent single-member First Instance Court. The process unfolds as follows:

1. File the original or certified copy of the arbitral award. The award must be duly authenticated (apostille or consular legalisation).
2. File the original arbitration agreement (or the relevant contract clause containing the arbitration provision).
3. Provide certified Greek translations of both the award and the arbitration agreement, prepared by an official translator.
4. Submit proof of service. Evidence that the award-debtor was properly notified of the arbitration proceedings and had an opportunity to present its case.
5. Pay the court filing fee. Fees are modest by international standards.
6. Serve the application on the award-debtor. Under the 2026 civil-procedure reform, electronic service may be used where the respondent is registered in the Greek electronic-service system.

In uncontested cases, recognition can be achieved relatively quickly. Where the award-debtor opposes enforcement, the court will schedule a hearing to consider the grounds for refusal set out in the New York Convention. This is the critical gateway for enforcing arbitral awards in Greece for foreign award-creditors, and the quality of the documentation package at filing stage materially affects both speed and outcome. For practitioners navigating international commercial arbitration more broadly, GLE’s dedicated guide provides essential context.

Defending enforcement & setting-aside grounds

Under Article V of the New York Convention, the award-debtor may resist enforcement on the following exhaustive grounds:

• Invalidity of the arbitration agreement, the agreement was not valid under the law to which the parties subjected it.
• Denial of due process, the award-debtor was not given proper notice of the proceedings or was unable to present its case.
• Excess of jurisdiction, the award deals with matters outside the scope of the arbitration agreement.
• Irregular tribunal composition, the tribunal was not constituted in accordance with the parties’ agreement or applicable law.
• Award not yet binding, the award has been set aside or suspended in the country of origin.
• Public policy, enforcement would be contrary to Greek public policy (narrowly construed by Greek courts).

Greek courts have consistently interpreted these grounds narrowly, reflecting a pro-enforcement bias that aligns with international best practice. The burden of proof falls squarely on the party opposing enforcement.

Post-award remedies and tactical enforcement

Once an award is recognised, execution follows, including the potential judicial sale of arrested vessels and priority of claims.

Execution mechanics

After a Greek court recognises a foreign arbitral award, the award-creditor obtains an enforceable title that can be executed through the standard enforcement mechanisms:

• Seizure and sale of the arrested vessel. Where a ship has been arrested to secure the claim, the award-creditor can proceed to judicial auction. The updated 2026 enforcement-agent procedures govern the auction timeline, advertisement requirements and distribution of proceeds.
• Garnishment of bank accounts. The recognised award serves as the basis for converting provisional freezing orders into permanent garnishment orders, enabling the creditor to collect directly from frozen funds.
• Seizure of other assets. Shares in Greek companies, real property, receivables and other assets of the award-debtor within Greek jurisdiction can all be targeted.

Priority of claims against the proceeds of a judicial sale follows the established maritime lien hierarchy, crew wages, salvage and collision claims rank ahead of contractual claims, which in turn rank ahead of unsecured creditors.

Defending execution

Award-debtors have limited but important tactical options. A stay of execution may be sought if the award is being challenged in the courts of the seat. Security offers, typically P&I club letters of undertaking (LOUs), can secure the release of an arrested vessel while enforcement proceedings continue. Industry observers expect that P&I clubs will continue to play a central role in providing such guarantees, as the commercial cost of a detained vessel far exceeds the cost of posting security.

Conclusion

Enforcing arbitral awards in Greece 2026 demands a dual-track approach: mastering the reformed arbitration framework under Law 5016/2023 and navigating the modernised civil-procedure system with speed and precision. Whether the objective is arresting a vessel in Piraeus, freezing bank accounts to prevent asset dissipation, or obtaining recognition of a London or ICC award against Greek-domiciled shipowner assets, the fundamentals remain constant, prepare documentation in advance, choose the right forum for the right remedy, and engage experienced local counsel early. Greece’s pro-enforcement judicial culture, combined with its position as the world’s largest shipowning nation, makes it a jurisdiction where effective enforcement strategy directly translates into commercial outcomes.
