How to Bring a Class (representative) Action in Greece in 2026, Step‑by‑step Procedure, Eligibility, Documents & Timeline

Last updated: 28 May 2026

Understanding how to bring a class action in Greece in 2026 is essential for consumer organisations, in‑house counsel and claimant law firms confronting mass‑harm events such as product defects, data breaches or anticompetitive conduct. Greece does not replicate the US‑style class action; instead, it operates a representative action framework anchored in Directive (EU) 2020/1828 (the Representative Actions Directive, or “RAD”) and shaped by broad civil‑procedure reforms introduced through Law 5221/2025 (FEK A’ 133/28.07.2025). This guide walks through every stage of the collective action procedure in Greece, from eligibility checks and document preparation to filing, case management, settlement approval and enforcement, reflecting the tighter deadlines and streamlined processes that Greek courts have begun applying since the start of 2026.

Overview of the Representative Action Process and Who It Applies To

A representative action in Greece allows a designated “qualified entity”, rather than an individual consumer, to seek injunctive relief, redress measures or both on behalf of a group of affected persons. The mechanism serves sectors where large numbers of consumers or businesses suffer comparable harm from the same trader practice, defective product or regulatory breach.

The substantive rules governing who may sue, what remedies are available and how the court supervises the action derive from Greece’s transposition of Directive (EU) 2020/1828. Procedural timelines, service windows, pleading deadlines and case‑management scheduling, are now governed by the Civil Procedure Code as amended by Law 5221/2025 (FEK A’ 133/28.07.2025), which tightened pre‑trial preparation, introduced strict calendaring and reduced scope for adjournments.

Typical use cases include mass consumer claims against financial institutions, product liability actions, competition‑damages follow‑on claims, and regulatory compliance disputes arising from EU‑harmonised legislation. The procedure is also available for cross‑border infringements where a qualified entity designated in another EU Member State meets the Greek standing requirements.

Eligibility and Prerequisites for a Class Action in Greece

Not every organisation can launch a representative action. The class action requirements in Greece centre on the concept of a “qualified entity”, an organisation pre‑designated or recognised as meeting specific governance and transparency standards. Failing the eligibility threshold is one of the most common reasons actions are dismissed at the outset.

Qualified Entity Types

Under the RAD transposition, the following categories may qualify:

• Recognised consumer associations. Organisations registered with the competent ministry and demonstrating at least 12 months of active consumer‑protection activity before filing. They must show genuine engagement, not a purpose created solely for litigation.
• Public bodies. Certain regulatory or supervisory authorities (e.g., the Consumer Ombudsman, specific chambers) that hold a statutory mandate to protect collective consumer interests.
• Trade unions and trade associations. Where the infringement falls within the scope of their members’ professional interests and the entity meets governance and reporting obligations set out in the RAD.
• Cross‑border qualified entities. Organisations designated in another EU Member State and included on the list published by the European Commission pursuant to Directive (EU) 2020/1828, provided they can demonstrate a connection to the Greek infringement.

To prove eligibility for a representative action in Greece, the entity must file its certificate of incorporation or statute, evidence of active operations (annual reports, membership records) and, critically, a board resolution expressly authorising the specific action.

Member‑Listing and Opt‑In / Opt‑Out Rules

Greece’s transposition generally follows an opt‑in model for redress measures: individual consumers must express their wish to be represented, either through signed mandates or through a documented enrolment mechanism operated by the qualified entity. For injunctive measures (cease‑and‑desist orders), no individual opt‑in is required because the relief benefits the collective interest automatically. The qualified entity must, however, describe the class of affected persons with sufficient precision at filing. Where a settlement is proposed, notice must be given to all identifiable class members, who then have a defined window to opt out.

How to Bring a Class Action in Greece, Step‑by‑Step Procedure

The following numbered steps reflect the collective action procedure in Greece as it operates under the 2026 framework. Each step corresponds to a row in the consolidated timeline table at the end of this section.

Step 1, Conduct Case Assessment and Gather Evidence

Before any filing, claimant counsel and the qualified entity must build the factual and legal foundation for the claim. Key tasks include:

• Identifying and interviewing sample affected consumers or businesses to define the scope of harm.
• Commissioning expert reports where technical causation or damage quantification is required (e.g., financial‑loss modelling, product‑defect analysis).
• Preparing a litigation‑funding plan, Greek law does not prohibit third‑party litigation funding, but disclosure to the court may be required.
• Compiling an exhibit index of primary evidence (contracts, invoices, marketing materials, regulatory correspondence).

This preparation phase typically takes 7–60 calendar days depending on the complexity of the underlying facts and the number of potential class members.

Step 2, Obtain Qualified Entity Board Approval and Issue Pre‑Filing Notice

The qualified entity’s governing body must pass a formal resolution authorising the action. This resolution should identify the defendant, the nature of the infringement, the remedies sought and the counsel appointed. In line with the transparency obligations under Directive (EU) 2020/1828, many qualified entities also publish a notice on their website announcing the intended action and inviting affected persons to register interest.

Although Greek law does not impose a mandatory pre‑action protocol for representative actions equivalent to the English system, early notification to the defendant can serve tactical purposes, it may prompt voluntary cessation of the infringement or open settlement channels before court costs accrue. Allow 7–30 calendar days for this stage.

Step 3, File the Statement of Claim at the Competent Court

The statement of claim is filed at the multi‑member first instance court (Polymeles Protodikeio) in the judicial district where the defendant has its registered seat or, in certain consumer matters, where the infringement produced its effects. The filing must include:

• The signed statement of claim, setting out the factual narrative, the legal basis (RAD transposition provisions, relevant consumer‑protection statutes) and the remedies sought (injunction, redress or both).
• A notarised power of attorney connecting counsel to the qualified entity.
• The entity’s certificates of incorporation, statute and board resolution.
• A member list or methodology for identifying the class.
• An exhibit index with key supporting evidence and expert reports.
• Draft notice materials intended for dissemination to the class.
• A court‑fee payment receipt or, where applicable, an exemption request.

Once the clerk registers the action, the claimant must arrange formal service on the defendant. Service must typically be completed within 3–14 calendar days of filing, following the Greek Code of Civil Procedure rules (as amended by Law 5221/2025). Where the defendant is domiciled abroad, service via the Hague Service Convention or the EU Service Regulation applies and takes longer.

Step 4, Court Case‑Management and Preliminary Measures

Under the revised scheduling rules introduced by Law 5221/2025 (FEK A’ 133/28.07.2025), the court issues a case‑management timetable shortly after service. The likely practical effect of the 2025 reforms is that pleading windows are tighter than under the prior regime: defence and reply briefs are commonly required within 30–90 calendar days of service, depending on the court’s order. Practitioners should expect judges to enforce these windows strictly and resist adjournments.

If the claimant needs urgent interim relief, for instance, a preliminary injunction to halt ongoing harm or preserve evidence, the application is filed alongside or immediately after the main claim. Expedited interim hearings typically take place within 7–30 calendar days. The court may also appoint its own expert or order disclosure of specific documents at this stage.

Step 5, Negotiate Settlement and Obtain Court Approval

Settlement is encouraged at any point, but a representative‑action settlement involving redress measures must receive court approval to bind the class. The settlement approval procedure involves:

1. Filing the proposed settlement agreement and a distribution plan with the court.
2. Issuing notice to all identifiable class members, giving them a court‑set period (commonly 30–60 calendar days) to opt out or object.
3. Attending a fairness hearing, at which the court evaluates whether the settlement adequately compensates class members and whether the notice was sufficient.
4. Receiving the court’s approval decision, which renders the settlement binding on all class members who did not opt out.

This process typically spans 30–120 calendar days from filing of the settlement to final approval, depending on the size of the class and the complexity of the distribution mechanism.

Step 6, Judgment, Enforcement and Opt‑Out Effects

If the case proceeds to judgment rather than settlement, the court issues a reasoned decision. A favourable judgment on injunctive relief takes effect immediately upon service; redress orders become enforceable after the appeal period lapses (typically 30 days from service of the reasoned decision) or after the appellate court confirms the decision.

Enforcement follows standard Greek civil‑enforcement rules. For monetary awards, the winning party may pursue seizure of bank accounts, attachment of assets or garnishment. Class members who opted out of the action are not bound by the judgment, whether favourable or unfavourable, and retain the right to pursue individual claims.

Consolidated Timeline Table

Required Documents for a Class Action in Greece

Assembling the correct documents needed for a class action is critical, missing or deficient filings can delay the action by weeks or provide the defendant with grounds to challenge standing. The following table sets out every document typically required at commencement and during the proceedings.

Practitioners should prepare a master filing bundle in both hard copy and electronic form. Courts in Athens and Thessaloniki increasingly accept or require electronic filing for certain document categories, though the statement of claim itself is still filed in hard copy at most Polymeles Protodikeio registries. It is advisable to confirm the specific filing requirements with the court clerk before submission.

Timeline for Representative Actions, Key Deadlines in 2026

The timeline for representative actions in Greece is shaped by both the RAD transposition and, since mid‑2025, the civil‑procedure reforms of Law 5221/2025. Early indications suggest that courts are enforcing the new scheduling provisions with greater rigour than the pre‑reform practice. The table below consolidates the critical deadlines that practitioners must calendar.

Missing a deadline can have severe consequences. Courts may strike late‑filed pleadings, refuse to admit evidence or dismiss interim applications. Where a deadline is missed, counsel should immediately file a restoration motion (aitisi epanaforis) explaining the reason for the delay, though success is not guaranteed, especially under the stricter ethos of Law 5221/2025. For litigation involving property‑related claims in Greece, parallel regulatory timelines may also need to be tracked.

Class Action Costs in Greece, Fees, Disbursements and Tax Considerations

Budgeting accurately is essential. Class action costs in Greece vary considerably depending on the claim value, the number of class members and whether injunctive or redress measures are sought. The following table provides indicative ranges for the main cost categories.

The losing party in Greek litigation is generally ordered to contribute to the winning party’s costs, though the award rarely covers the full amount. In representative actions, courts have discretion over cost allocation and may take into account the public‑interest nature of the claim. Where third‑party funders are involved, disclosure requirements should be checked against current court practice, which is still evolving.

What Changes in 2026, Key Reforms Affecting Representative Actions

Two legislative instruments define the current landscape for anyone considering how to bring a class action in Greece in 2026:

• Law 5221/2025 (FEK A’ 133/28.07.2025). This sweeping Civil Procedure Code reform introduced stricter case‑management timetables, shortened pleading windows, reduced tolerance for adjournments and piloted electronic‑filing enhancements. While the law addresses civil litigation broadly, its scheduling and enforcement provisions apply directly to representative actions heard in the multi‑member first instance courts. Courts have been applying these provisions in earnest since early 2026, and industry observers expect further implementing orders to refine electronic‑filing mandates later in the year.
• Directive (EU) 2020/1828 (Representative Actions Directive). Greece’s national transposition established the qualified‑entity framework, the dual‑track remedy system (injunctive and redress measures) and the settlement‑approval procedure. The RAD remains the substantive backbone, while Law 5221/2025 provides the procedural engine. Practitioners must read the two instruments together to understand current timelines and filing obligations.

The likely practical effect of these combined reforms is faster case resolution, more structured pre‑trial preparation and greater judicial oversight of settlement quality, all of which raise the bar for claimant preparation but also reduce the scope for defensive delay tactics by respondents. Greece’s broader 2026 regulatory reform programme also signals a continued emphasis on procedural efficiency across multiple areas of law.

Common Pitfalls and How to Avoid Them

• Insufficient evidence at filing. Courts expect a fully developed factual case at commencement. Avoid skeletal claims: commission expert reports and compile the exhibit index before filing rather than requesting time to supplement later.
• Failure to prove qualified‑entity standing. A missing or outdated board resolution, expired registration certificate or inadequate proof of 12 months’ active operations will invite an immediate challenge. Include all standing documents in the filing bundle and ensure they are dated within the accepted validity window.
• Inadequate notice plan for settlement approval. The court will scrutinise how class members were informed. Prepare multi‑channel notice templates (post, email, website publication, press advertisements) well in advance and document dissemination with delivery receipts.
• Mismatched court venue. Filing in the wrong judicial district wastes time and costs. Verify the defendant’s registered seat (or the locus of harm, where consumer‑protection rules permit alternative venue) before drafting the statement of claim.
• Overlooking Law 5221/2025 scheduling rules. The reformed deadlines are substantially tighter. Calendar every court‑ordered date immediately upon receipt, build in buffer periods for document preparation and request a case‑management conference at the earliest opportunity to clarify the timetable.
• Neglecting data‑privacy obligations. Member lists and evidence may contain personal data subject to the GDPR and Greek data‑protection law. Redact personal identifiers where possible and prepare a data‑processing protocol agreed with the qualified entity before sharing information with the court or opposing party.
