1. Introduction

Multi-claimant litigation management refers to the legal and procedural mechanisms used when a large number of claimants have disputes arising from the same, similar, or connected facts or legal issues.

Typical examples include:

• purchasers bringing claims against the same property developer;
• investors bringing claims arising from the same investment scheme;
• employees bringing similar contractual claims;
• consumers affected by the same product or service;
• shareholders pursuing related claims;
• creditors pursuing claims involving the same transaction;
• policyholders bringing connected insurance claims;
• multiple parties affected by the same corporate or financial misconduct.

The UAE does not have one single procedural model applicable to every multi-claimant dispute. The appropriate structure depends heavily on the court, jurisdiction, applicable procedural legislation, nature of the claims, and degree of factual/legal commonality.

A particularly developed mechanism exists in the DIFC Courts, whose current Rules expressly provide for Group Litigation Orders (GLOs), consolidation, group registers, test claims, lead legal representatives, common issues and individual issues.

It is important to distinguish this from ordinary joinder or consolidation. A group litigation structure is a case-management mechanism for managing multiple related claims; it does not necessarily transform every claimant's individual cause of action into one identical claim.

2. Meaning of Multi-Claimant Litigation

Multi-claimant litigation exists where:

Two or more claimants have separate or related claims against one or more defendants and efficient administration of justice requires those claims to be managed together or in a coordinated manner.

There can be different degrees of connection.

Level 1 — Common defendant

Example:

100 purchasers sue the same developer.

Level 2 — Common facts

The purchasers rely upon the same development delay and similar contractual documents.

Level 3 — Common legal issues

All claimants argue that the developer breached the same contractual obligation.

Level 4 — Common liability issue but different damages

The court may determine liability collectively while calculating each claimant's loss separately.

Level 5 — Fully structured group litigation

The court establishes:

• a group register;
• common issues;
• test claims;
• lead representatives;
• common evidence;
• individual issues;
• common-cost arrangements.

The DIFC Rules expressly contemplate this last structure.

3. Why Multi-Claimant Structures Are Necessary

Without effective management, 100 related cases could produce:

• repeated evidence;
• multiple expert reports;
• duplicated hearings;
• inconsistent judgments;
• excessive legal costs;
• unnecessary disclosure;
• different procedural timetables;
• repeated arguments concerning the same legal issue.

Therefore, litigation management seeks to achieve:

Efficiency

One determination of genuinely common questions can avoid repetition.

Consistency

Common issues can be decided consistently.

Cost control

Duplicated litigation expenses can be reduced.

Judicial economy

Court resources can be allocated proportionately.

Procedural fairness

At the same time, each claimant must retain an opportunity to establish matters unique to his or her claim.

4. Multi-Claimant Litigation Is Not the Same as a Class Action

This distinction is extremely important.

A traditional class action may allow one representative or class structure to litigate on behalf of a defined class.

A multi-claimant proceeding can instead involve individually named claimants whose claims are:

• joined;
• consolidated;
• managed together;
• placed on a group register;
• determined through test cases.

The DIFC GLO framework is closer to structured group litigation than to assuming that all claimants automatically possess one identical cause of action.

5. Main Multi-Claimant Management Structures

A. Joinder

Joinder brings multiple parties into the same proceeding where procedural rules permit.

It may involve:

• multiple claimants;
• multiple defendants;
• additional parties;
• third parties.

The objective is generally to ensure that connected disputes can be resolved efficiently.

The DIFC Rules specifically provide mechanisms for addition and substitution of parties and establish procedures for cases involving numerous parties.

6. Consolidation

Consolidation combines two or more separate proceedings so that they can proceed together.

It is particularly useful where:

• the defendant is the same;
• factual issues overlap;
• legal issues overlap;
• evidence overlaps;
• separate trials could produce inconsistent outcomes.

The court can determine whether consolidation advances the overriding objective and whether it saves expense and judicial resources.

7. Group Litigation Order — GLO

The DIFC Courts provide an expressly structured Group Litigation Order.

Under current DIFC Rule 20.70, a GLO is an order for the case management of claims raising common or related issues of fact or law. Rule 20.72 permits a GLO where there are or are likely to be several claims giving rise to common issues.

The application can be made:

• by a claimant;
• by a defendant;
• before or after relevant claims have been issued.

The application should identify:

1. the nature of the litigation;
2. existing claims;
3. anticipated number of parties;
4. common factual/legal issues;
5. matters distinguishing smaller groups of claims.

8. Group Register

A central feature of GLO litigation is the group register.

Claims that satisfy the relevant criteria can be entered onto the register.

The register allows the court and parties to identify:

• who belongs to the litigation group;
• which claims raise common issues;
• which claims are being managed together.

The DIFC Rules require the GLO to establish a group register and identify the relevant GLO issues.

This is particularly useful where the number of claimants changes over time.

9. Common Issues and Individual Issues

This is perhaps the most important structural principle.

Common issues

Questions shared by many claimants, such as:

• Was the defendant negligent?
• Was a particular contract term unlawful?
• Was a particular representation false?
• Did a particular event constitute breach?
• Is a particular contractual clause enforceable?

Individual issues

Questions unique to each claimant, such as:

• How much did claimant A lose?
• Did claimant B rely on the representation?
• What damages did claimant C actually suffer?
• Does claimant D have a limitation problem?

The DIFC Rules expressly permit directions for the trial of common issues and individual issues separately.

This creates a two-stage model:

Common liability → Individual entitlement/damages

10. Test Claims

The court may select one or more claims as test claims.

A test claim can help determine common issues before the court deals with every individual claim.

For example:

100 investors bring similar claims.

The court may select 2–5 representative cases to examine:

• contractual interpretation;
• liability;
• validity of representations;
• causation.

After determining common questions, individual claims can proceed on their particular facts.

The DIFC Rules expressly permit the court to direct one or more claims on the group register to proceed as test claims.

11. Lead Legal Representative

Large-scale litigation creates a practical problem:

Who communicates with the court on behalf of dozens or hundreds of claimants?

A group-management order may appoint a lead legal representative.

The lead representative can coordinate:

• procedural applications;
• common evidence;
• group communications;
• common submissions;
• administration of group litigation.

The current DIFC Rules expressly permit appointment of a lead legal representative for claimants or defendants.

This does not necessarily mean that every claimant loses individual legal representation or decision-making authority.

12. Common Evidence

Multi-claimant litigation can involve enormous amounts of evidence.

Instead of requiring every claimant to reproduce identical evidence, the court can structure evidence around common questions.

For example:

Common evidence

• master contract;
• developer's project records;
• common expert report;
• common emails;
• corporate records.

Individual evidence

• claimant's payment records;
• individual correspondence;
• individual loss calculations;
• personal reliance evidence.

The purpose is to prevent repetitive litigation while preserving individual justice.

13. Binding Effect of Determinations

The DIFC GLO framework contains an important mechanism concerning judgments on common issues.

Under Rule 20.86, a judgment or order concerning GLO issues is generally binding on parties to claims already on the group register, subject to the court's directions and exceptions in the Rules. Later-added claimants have specific mechanisms for arguing that an earlier judgment should not bind them.

This is why entry onto a group register has substantial procedural consequences.

14. Disclosure and Document Sharing

Group litigation can also simplify documentary evidence.

Under the DIFC Rules, unless the court orders otherwise, production of a document relating to GLO issues by one group litigant can constitute production to other group-register claimants concerning those issues.

This can prevent:

Claimant 1 requests the same document → Claimant 2 requests it again → Claimant 3 requests it again.

Instead, common disclosure can be centrally managed.

15. Costs Management

Multi-claimant litigation creates complex costs questions.

The DIFC Rules distinguish between:

Common costs

Costs associated with:

• GLO issues;
• test claims;
• administration by the lead legal representative.

Individual costs

Costs relating specifically to an individual claimant's case.

The Rules generally provide for group litigants to bear an equal proportion of common costs unless the court orders otherwise.

This distinction is essential because not every claimant should automatically bear every cost generated by another claimant's unique dispute.

16. Consolidation vs GLO

17. Important Case Laws

Case 1 — Amit Dattani & Others v DAMAC Park Towers Co Ltd

[2012] DIFC CFI 034

This is one of the most directly relevant DIFC authorities.

There were separate proceedings involving different groups of claimants against the same defendant. The causes of action were the same and the defendant was the same.

The proceedings were consolidated.

The judgment records that although the joint claimants in the two proceedings were not identical, their causes of action and defendant were the same.

Principle

Different claimants can have their proceedings managed together when common causes of action and common defendants make coordinated determination appropriate.

Importance

This is a useful example of the transition from separate proceedings toward structured multi-claimant litigation.

18. Case 2 — CFI 034/2012 & CFI 046/2012 Consolidation/GLO Directions

The DIFC Court consolidated two proceedings and simultaneously dealt with an application for a Group Litigation Order.

The court established directions concerning:

• pleadings;
• requests for further information;
• defence;
• evidence;
• case-management hearings.

Principle

Consolidation and group litigation management can operate together.

Importance

The case demonstrates that multi-claimant litigation is not simply about putting names together; it requires a detailed procedural architecture.

19. Case 3 — Nest Investment Holding Lebanon S.A.L. & Others v Deloitte & Touche (M.E.)

[2018] DIFC CA 011

This is an important authority concerning joinder of parties.

The DIFC Court of Appeal held that Rule 20.7 gave the court a discretionary power to add a party where the relevant criteria were satisfied.

The Court emphasised the value of having all relevant parties before the court to avoid inconsistent decisions and unnecessary additional litigation.

Principle

Joinder can promote comprehensive and consistent resolution of interconnected disputes.

Importance

It illustrates the relationship between jurisdiction, procedural joinder and effective case management.

20. Case 4 — Westford Trade Services DMCC & Westford Trade Services (UK) Ltd v Dubai Insurance Co PSC

[2023] DIFC CFI 033/2022

Two separate claims were consolidated.

The court explained that its case-management powers to consolidate proceedings should be exercised consistently with the overriding objective, including:

• saving expense;
• expeditious and fair resolution;
• appropriate use of court resources.

Principle

Consolidation is fundamentally a case-management tool directed toward justice, efficiency and proportionality.

Importance

This is highly relevant to modern multi-claimant litigation management.

21. Case 5 — Kian Saadat Yazdi & Hassan Saadat Yazdi v Barclays Bank PLC

[2019] DIFC CFI 036/2019 & 039/2019

Two separate proceedings involving different claimants against the same defendant were consolidated by consent under Rule 4.2(7).

The court then managed the claims together, including amendment of the claim forms and a stay reflecting the parties' settlement arrangements.

Principle

Where claims are sufficiently connected, consolidation can facilitate coordinated procedural treatment even when the claimants remain individually identifiable.

22. Case 6 — Alexander Reuter & Others v Wellness United Inc & Others

[2023] DIFC CFI 107/2021 & 108/2021

Two related proceedings were consolidated, managed and tried together.

The court also required the pleadings and evidence to be structured against an agreed list of issues.

Principle

Consolidation can be accompanied by issue-based case management to prevent evidence and submissions from becoming unnecessarily repetitive.

Importance

This is particularly relevant to complex multi-party disputes.

23. Case 7 — Emirates NBD Bank PJSC & Others v Advanced Facilities Management LLC & Others

[2022] DIFC CFI 065/2020

This litigation involved numerous claimants and defendants and included an issue concerning joinder of an additional claimant.

The court's directions demonstrate the practical importance of managing numerous parties and procedural amendments within complex litigation.

Principle

Multi-party litigation requires active judicial control over joinder, pleadings, evidence and hearing management.

24. Current DIFC Group Litigation Structure

The current DIFC framework can be represented as follows:

Multiple claims

↓

Identify common issues

↓

Application for GLO

↓

Group Litigation Order

↓

Group register

↓

Lead legal representative

↓

Common disclosure/evidence

↓

Test claims

↓

Determination of common issues

↓

Individual claims/damages

↓

Individual remedies

This is a sophisticated case-management structure rather than a simple class-action model.

25. Multi-Claimant Litigation and UAE Mainland Courts

A major distinction must be maintained between mainland UAE courts and the DIFC Courts.

The DIFC has an expressly codified GLO framework in its Rules of Court.

Therefore, the existence of a DIFC GLO mechanism should not be described as automatically applicable to every mainland UAE civil proceeding.

For a mainland case, the applicable federal/local procedural rules and the court's jurisdiction must be examined.

This distinction is especially important when drafting legal opinions because DIFC procedural rules cannot simply be transplanted into a mainland Dubai or Abu Dhabi proceeding.

26. Relationship With the UAE Civil Transactions Law

Multi-claimant litigation is primarily a procedural/case-management question, while the Civil Transactions Law generally supplies substantive civil principles.

For example, a group of 200 purchasers might rely upon:

• breach of contract;
• misrepresentation;
• defective performance;
• compensation;
• restitution;
• unjust enrichment.

The procedural court rules determine how those claims are managed.

The substantive civil law determines whether those claims succeed and what remedies are available.

Therefore:

Substantive law = rights and liabilities

Procedural law = mechanism for enforcing those rights

27. Multi-Claimant Litigation in Construction Disputes

Construction projects are particularly suitable for structured multi-party management.

For example:

• 50 apartment purchasers;
• one developer;
• one contractor;
• several subcontractors;
• common delay;
• common defects.

The court may need to separate:

Common questions

• Was there a systemic construction defect?
• Was the developer contractually responsible?
• Was the project delayed?

Individual questions

• Which apartment was affected?
• What defect exists?
• What amount did each purchaser pay?
• What individual loss occurred?

This is exactly the kind of common-versus-individual structure that a sophisticated group-management system is designed to address.

28. Multi-Claimant Investor Litigation

Investment disputes may involve:

• common representations;
• common offering documents;
• common investment structures;
• common corporate conduct.

But investors may have different:

• investment amounts;
• dates of purchase;
• contractual terms;
• reliance;
• losses.

Consequently, collective determination of liability may be efficient while individual damages remain separate.

29. Consumer Claims

Multi-claimant structures can also be relevant to consumer disputes involving:

• defective products;
• common service failures;
• misleading representations;
• recurring billing practices;
• digital platforms.

However, whether such claims can be formally grouped depends upon the applicable procedural and substantive framework.

The mere existence of numerous consumers does not automatically create a class action.

30. Advantages of Multi-Claimant Litigation

1. Reduced duplication

Common issues need not be litigated repeatedly.

2. Lower aggregate costs

Shared evidence and common procedural work can reduce duplication.

3. Consistency

Common questions can receive a common judicial determination.

4. Efficient use of experts

One common expert issue can potentially be addressed through coordinated evidence.

5. Better judicial resource allocation

The court can devote resources according to the complexity of the dispute.

6. Faster determination of common questions

Test claims can resolve central issues before individual claims are addressed.

31. Risks and Challenges

Multi-claimant structures also create problems.

Different factual circumstances

Not every claimant may have the same facts.

Conflicts of interest

Claimants may disagree over:

• settlement;
• damages;
• litigation strategy;
• costs;
• expert evidence.

Unequal damages

One claimant may have suffered AED 50,000 in loss while another suffered AED 5 million.

Limitation differences

Different claimants may have different limitation positions.

Settlement difficulties

A settlement acceptable to one claimant may be unacceptable to another.

Procedural unfairness

If common issues are treated too broadly, an individual claimant may lose the opportunity to establish an important individual fact.

This is why the distinction between common issues and individual issues is fundamental.

32. Safeguards for Individual Claimants

A good multi-claimant structure should preserve:

1. individual pleadings where necessary;
2. individual evidence;
3. individual damages assessment;
4. independent legal advice;
5. procedural participation;
6. opportunity to challenge common findings where legally justified;
7. protection against conflicts of interest;
8. transparent costs allocation.

The DIFC GLO framework contains specific mechanisms for later-added claims and circumstances in which a party may seek an order that a prior judgment is not binding on it.

33. Role of the Judge

The judge becomes not merely an adjudicator but also an active case manager.

The court may need to decide:

• who belongs in the group;
• which issues are genuinely common;
• which cases should be test claims;
• which evidence is common;
• who should act as lead representative;
• whether cases should remain consolidated;
• how costs should be allocated;
• when individual issues should be tried.

The objective is not simply administrative convenience. It is fair and proportionate adjudication.

34. Case Management Model

A useful UAE multi-claimant litigation model is:

Stage 1 — Identification

Identify all related claims.

Stage 2 — Classification

Separate common and individual issues.

Stage 3 — Procedural structure

Choose:

• joinder;
• consolidation;
• GLO;
• separate but coordinated proceedings.

Stage 4 — Leadership

Identify lead representatives and lawyers where appropriate.

Stage 5 — Evidence

Separate common evidence from individual evidence.

Stage 6 — Test cases

Determine appropriate representative claims.

Stage 7 — Common determination

Resolve common legal/factual questions.

Stage 8 — Individual determination

Assess each claimant's specific entitlement.

Stage 9 — Remedies

Calculate individual damages or other relief.

Stage 10 — Costs

Allocate common and individual costs.

35. Important Case-Law Revision Table

These are predominantly DIFC authorities, and therefore should be cited as DIFC procedural jurisprudence rather than automatically as binding mainland UAE precedent.

36. Quick Revision Points

For examination or research purposes, remember:

Multi-Claimant Litigation =

Many claimants + related claims + coordinated judicial management.

Main mechanisms:

1. Joinder
2. Consolidation
3. Group Litigation Order
4. Group Register
5. Test Claims
6. Lead Legal Representative
7. Common Issues
8. Individual Issues
9. Common Evidence
10. Common and Individual Costs

Most important procedural distinction:

Common liability does not necessarily mean identical individual damages.

Most important management principle:

The court should combine genuinely common questions while preserving individual determination where the facts require it.

Most important UAE-specific point:

The DIFC Courts have an express and sophisticated GLO framework, including group registers, test claims, lead representatives and common/individual issue trials.

Conclusion

Multi-claimant litigation management structures are increasingly important for complex UAE civil disputes involving numerous purchasers, investors, consumers, shareholders, employees or other affected parties.

The principal mechanisms are joinder, consolidation and structured group litigation. The DIFC Courts provide the clearest codified example through their GLO regime, which allows the court to identify common issues, establish a group register, appoint lead representatives, select test claims, manage common disclosure, and subsequently determine individual issues.

The central legal philosophy can be summarised as:

Efficiency + consistency + proportionality + individual fairness.

The ultimate objective is not simply to put numerous claimants into one proceeding, but to create a structure in which common questions are decided once where appropriate, while each claimant retains the necessary opportunity to establish individual liability, causation, loss and remedy.
