How to Commence a Maritime Arbitration in Greece: Step‑by‑step 2026 Guide

Understanding how to commence maritime arbitration in Greece is essential for any shipowner, charterer, P&I club or insurer facing a shipping dispute that triggers an arbitration clause pointing to a Greek seat. Greece has materially modernised its arbitration framework through Law 5016/2023 (the International Commercial Arbitration Act), expanding arbitrability, streamlining court assistance for interim measures and aligning the country’s regime with the UNCITRAL Model Law. This guide sets out the complete maritime arbitration process in Greece as it stands in 2026, from clause verification and filing the Request for Arbitration through to tribunal constitution, evidence handling, costs and enforcement planning.

It is designed as a practical, client-ready checklist rather than a high-level commentary, and every procedural step references the applicable statute or institutional rule.

Overview of the Maritime Arbitration Process in Greece

“Commencing an arbitration” in Greece means the claimant formally invokes the arbitration agreement by serving a Request for Arbitration (or Notice of Arbitration) on the respondent and, if the parties have chosen institutional rules, filing that Request with the relevant institution. Two distinct legal regimes may apply depending on the nature of the dispute. Domestic arbitral proceedings are governed by the Seventh Book of the Greek Code of Civil Procedure (GrCCP), Articles 867–903. International commercial arbitrations seated in Greece, the category into which most cross-border maritime disputes fall, are now governed by Law 5016/2023.

Common maritime claim types that proceed to Greek-seated arbitration include unpaid hire or freight, cargo damage, bunker disputes, collision and salvage claims, demurrage, and contractual disputes arising under charterparties or shipbuilding contracts. Parties must hold a valid written arbitration agreement, this can take the form of a clause in the charterparty, a standalone agreement or even an exchange of communications that records the parties’ consent. Under Law 5016/2023, the “writing” requirement is satisfied by any form that provides a record of the agreement, including electronic communications.

When to Choose Greece as the Seat of Arbitration

Selecting Greece, and specifically Piraeus, as the seat of arbitration offers several practical advantages. Piraeus hosts the Piraeus Association for Maritime Arbitration (PAMA), a non-profit institution founded in 2005 that administers maritime arbitrations under its own rules, modelled on the UNCITRAL framework. Greece’s court infrastructure provides rapid interim relief, including precautionary ship arrest through the Maritime Court of Piraeus. The 2023 reforms under Law 5016/2023 have broadened the scope of arbitrability and reinforced the pro-arbitration stance of Greek courts, making the seat of arbitration Greece an increasingly competitive choice for international maritime disputes.

Eligibility and Prerequisites for Maritime Arbitration in Greece

Before commencing proceedings, the claimant must verify several arbitration procedure requirements under Greek law. The foundational requirement is a valid arbitration agreement. Law 5016/2023 establishes that any dispute is arbitrable unless a specific statutory provision expressly prohibits arbitration. This represents a significant expansion from the narrower arbitrability standards that applied under the prior regime, where certain categories of disputes (including some employment-related maritime claims) were treated as non-arbitrable.

A party may commence arbitration regardless of nationality, foreign companies are fully entitled to commence arbitration seated in Greece, provided they can demonstrate capacity and proper authorisation. The claimant must also confirm that any contractual pre-conditions to arbitration (such as mandatory negotiation or mediation windows, or tiered dispute resolution clauses) have been satisfied or have expired.

Capacity and Corporate Authority Checklist

• Power of attorney. Ensure the person signing the Request has authority to bind the company. Prepare a board resolution or power of attorney and have it notarised or apostilled if the company is incorporated outside Greece.
• Corporate status evidence. Gather a certificate of incorporation, certificate of good standing or equivalent, and details of registered agents for service.
• Insurer / P&I club notification. Notify the club or insurer immediately, many policies contain notification clauses that, if missed, can prejudice cover.

Clause Verification Checklist

Before drafting the Request, review the arbitration clause for each of the following elements:

• Seat. Is the seat expressly stated as Greece or Piraeus? If not, the parties may agree a Greek seat by subsequent written agreement.
• Institutional rules. Does the clause nominate PAMA Rules, ICC Rules, LMAA Terms, UNCITRAL Rules or another set? This determines the filing procedure.
• Number of arbitrators. Sole arbitrator or three-member tribunal? If the clause is silent, Law 5016/2023 defaults to three arbitrators for international arbitrations.
• Language. Confirm the language of the arbitration. If the clause is silent, the tribunal will determine the language after constitution.
• Emergency arbitrator. Check whether the institutional rules provide for an emergency arbitrator and whether the parties have opted in or out.
• Governing law. Distinguish the law governing the substance of the dispute from the law of the seat (lex arbitri), which for Greek-seated arbitrations is Law 5016/2023.

How to Commence Maritime Arbitration in Greece: Step‑by‑Step Procedure

The following six steps map the complete process from instruction through to award and enforcement. Each step is described with the action required, the responsible party and the typical timeframe.

Step 1, Confirm the Arbitration Agreement and Select Seat and Rules

The first practical action is to instruct experienced maritime arbitration counsel and carry out the clause verification described above. If the clause is ambiguous about the seat, negotiate a written confirmation with the counterparty that Greece will be the seat. Determine whether the arbitration is institutional (filed with PAMA, ICC or another body) or ad hoc (governed by UNCITRAL Rules or parties’ own procedure). At the same time, take immediate steps to preserve evidence, issue hold notices to crews, agents and surveyors, photograph damage and secure the casualty scene. Notify P&I clubs, insurers and any guarantors. This step typically takes 1–3 days from instruction.

Step 2, Draft and File the Request for Arbitration

The Request for Arbitration is the document that formally commences the proceeding. While the precise format varies by institutional rules, a compliant Request for Arbitration in a Greek-seated case should include the following elements:

1. Full names, addresses and contact details of claimant and respondent.
2. A reference to the arbitration agreement and the relevant clause.
3. A summary of the claim, including the factual and legal grounds.
4. The relief sought and, where possible, the monetary quantum.
5. The claimant’s nomination of arbitrator (if a three-member tribunal) or proposal for a sole arbitrator.
6. The seat of arbitration, chosen institutional rules and language of the proceedings.
7. Signature of the authorised representative and any supporting power of attorney.

For institutional arbitrations, file the Request with the relevant institution’s secretariat together with the filing fee. For PAMA arbitrations, the Request is filed at the PAMA secretariat in Piraeus. For ad hoc proceedings, the claimant serves the Notice of Arbitration directly on the respondent in accordance with the arbitration agreement and any applicable rules (typically UNCITRAL). Proof of service, whether by certified delivery, courier receipt or email with read confirmation, must be retained. The drafting and filing stage typically takes 3–14 days depending on the complexity of the claim and internal approvals required.

Step 3, Apply for Interim Measures and Emergency Relief

Interim measures in Greece can be sought both from the arbitral tribunal (once constituted) and from the national courts. Where the tribunal has not yet been constituted and urgent relief is needed, such as a precautionary arrest of a vessel, a freezing order over assets, or an injunction to preserve evidence, the claimant may apply to the competent Greek court. For maritime disputes in the Attica region, the Maritime Court of Piraeus has exclusive jurisdiction.

Law 5016/2023 expressly confirms that applications to Greek courts for interim measures are compatible with the arbitration agreement and do not constitute a waiver of the right to arbitrate. Where institutional rules provide for an emergency arbitrator mechanism, the claimant can request the appointment of an emergency arbitrator to order interim relief even before the full tribunal is constituted. In practice, court applications for ship arrest in Piraeus can be processed within hours on an urgent basis. Claimants should prepare supporting affidavits, evidence of the underlying claim and evidence of urgency before making such applications.

Step 4, Constitute the Tribunal and Hold the Preliminary Conference

Once the Request has been served and any emergency measures are in place, the arbitrator appointment process begins. In a three-member tribunal, each party nominates one arbitrator, and the two party-nominated arbitrators select the presiding arbitrator. If a party fails to nominate within the time prescribed by the applicable rules or by Law 5016/2023, the appointing authority (the institution or, for ad hoc cases, the competent Greek court) will make the appointment.

Following constitution, the tribunal convenes a preliminary case management conference. At this conference the tribunal issues a procedural order (Procedural Order No. 1) that sets out the timetable for submissions, document production, witness statements, expert reports and hearings. This is also the stage at which issues such as confidentiality, electronically stored information (ESI) preservation and bifurcation of issues are addressed. The tribunal may order provisional measures at any time after constitution.

Step 5, Manage Evidence, Witnesses and Expert Procedures

Evidence in Greek-seated maritime arbitrations follows the schedule set in the procedural order. The claimant submits a statement of claim with supporting documents, followed by the respondent’s statement of defence and counterclaim (if any). Subsequent rounds of submissions and document production follow. Witness evidence is typically submitted as written witness statements, with cross-examination at the hearing. Expert evidence, from surveyors, naval architects, quantity surveyors or marine engineers, follows a similar process, often with joint expert meetings to narrow issues.

Critically, casualty evidence must be preserved as early as possible. This means issuing evidence hold notices to crew members, port agents, classification societies and P&I correspondents, securing logbooks and voyage data recorders, and commissioning independent surveys within days of the incident.

Step 6, Receive the Award and Plan for Enforcement

The tribunal issues a final award after the hearing and any post-hearing submissions. Under Law 5016/2023, the award must be in writing and signed by the arbitrators. If enforcing the award in Greece, the winning party may need to file the award with the competent Greek court. Greece is a signatory to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, so Greek-seated awards are enforceable in over 170 jurisdictions. Grounds for setting aside an award under Law 5016/2023 are limited and mirror the UNCITRAL Model Law, including incapacity of a party, invalidity of the arbitration agreement, procedural irregularity, excess of jurisdiction and public policy.

Documents Needed for Maritime Arbitration in Greece

Assembling the correct documents at the outset accelerates the process and avoids procedural objections. The table below lists the essential documents needed for arbitration in Greece, together with practical notes on format and preparation.

Practical Tips for Document Preparation and E‑Service

Digital signatures are generally accepted in Greek-seated arbitrations where the institutional rules permit. Documents should be filed in PDF/A format to ensure long-term readability. Where documents are in Greek and the arbitration language is English, certified translations must be arranged, using a sworn translator (episimos metafrastis) recognised by the Greek Ministry of Foreign Affairs. Parties should maintain a single, indexed electronic bundle and exchange documents through a shared platform or the institution’s case management system.

Arbitration Timeline in Greece: Key Deadlines

The overall duration of a maritime arbitration seated in Greece depends on the complexity of the dispute, the number of parties, the volume of evidence and whether interim relief applications intervene. For a mid-complexity maritime dispute with a three-member tribunal, industry observers expect a total timeline of approximately 6–18 months from filing the Request to issuance of the award. Simple disputes (e.g., demurrage claims with limited factual issues) may be resolved more quickly, while multi-party casualties or technical disputes may extend beyond 18 months.

Key deadline triggers to watch include the following. Under most institutional rules, the respondent must file a response to the Request within 30 days of receipt. Arbitrator nominations are typically due within 15–30 days. Applications to set aside an award under Law 5016/2023 must generally be filed within three months of receipt of the award. For interim relief applications to Greek courts, time is of the essence, in urgent ship arrest cases, same-day applications are common. All deadlines run from the date of receipt or service unless the applicable rules specify otherwise.

Arbitration Costs in Greece: Fees, Expenses and Tax Considerations

The total cost of a maritime arbitration seated in Greece varies widely depending on the institutional rules chosen, the size of the claim and the complexity of the evidence. The table below sets out the main cost categories and indicative ranges. All figures are estimates; parties should verify current fee schedules directly with the relevant institution and counsel.

Key cost drivers include the number of arbitrators, the volume of expert evidence, the length of hearings and whether emergency relief applications are required. Parties should budget for the possibility of counterclaims and any adverse costs orders. Greek VAT (currently 24%) applies to counsel and expert fees for services rendered in Greece.

What Changes in 2026: Law 5016/2023 and Implementation Updates

Law 5016/2023, the International Commercial Arbitration Act, entered into force upon its publication in the Official Gazette on 4 February 2023. It replaced the prior framework under Law 2735/1999 (which transposed the UNCITRAL Model Law with amendments) and introduced a modernised regime specifically tailored to international commercial arbitrations seated in Greece. The practical implications for parties commencing maritime arbitration in 2026 are significant.

• Expanded arbitrability. Law 5016/2023 establishes that any dispute is arbitrable unless a specific statutory provision prohibits it. This reverses the narrower approach previously applied by some Greek courts and removes uncertainty around the arbitrability of certain maritime claims.
• Court assistance for interim measures. The law expressly permits parties to seek interim measures from Greek courts both before and after the tribunal is constituted, without waiving the arbitration agreement. This is critical for urgent ship arrest applications in Piraeus.
• Conflict-of-laws rule. Article 11 of Law 5016/2023 provides clear rules on the law applicable to the substance of the dispute, the arbitration agreement and the arbitral procedure, reducing the risk of jurisdictional challenges.
• Award filing requirements. The law sets out specific obligations regarding the form, content and filing of arbitral awards. Parties enforcing in Greece should review the filing requirements to ensure compliance.
• Institutional oversight. Implementation activity during 2024–2026 has introduced administrative requirements for arbitral institutions operating in Greece, including registration and reporting obligations under Ministry of Justice oversight.

The likely practical effect of these reforms is that parties considering a Greek seat in 2026 will find a more predictable and enforcement-friendly environment than under the prior regime. Industry observers expect an increase in the number of international maritime arbitrations seated in Greece as awareness of the reformed framework grows. Parties drafting new charterparties or contracts should consider updating their arbitration clauses to expressly reference the seat of arbitration as Greece, specify the applicable institutional rules and include an emergency arbitrator opt-in clause.

Common Pitfalls in Greek Maritime Arbitration and How to Avoid Them

• Vague or missing seat clause. An arbitration clause that fails to specify the seat creates jurisdictional uncertainty and potential satellite litigation. Always state the seat expressly, for example: “The seat of arbitration shall be Piraeus, Greece.”
• Failure to preserve evidence immediately. In maritime casualties, critical evidence (logbooks, VDR data, physical damage, crew testimony) deteriorates or becomes unavailable within days. Issue evidence hold notices and commission surveys as soon as the incident occurs.
• Delay in applying for interim measures. Precautionary ship arrest requires urgency. A vessel may leave port, making arrest impossible. Prepare court applications in advance and file at the earliest opportunity.
• Service errors. Failure to serve the Request for Arbitration in strict compliance with the applicable rules can lead to jurisdictional challenges and delay. Use the service method prescribed by the institutional rules and retain full proof of delivery.
• Choosing the wrong institutional rules. Parties sometimes draft clauses referencing rules that are incompatible with a Greek seat or that do not provide for emergency arbitrators. Verify compatibility with the Greek lex arbitri before finalising clauses.
• Ignoring enforcement strategy at the outset. Consider where the respondent’s assets are located and whether the award will need enforcement outside Greece. Structure the claim and the arbitration clause to facilitate enforcement under the New York Convention from the start.
