Civil Law and UAE: Fragmentation of Global Legal Systems Theory

1. Meaning of the Theory

Fragmentation of global legal systems refers to the situation in which international legal relationships are governed by multiple, overlapping and sometimes competing legal systems rather than by one unified global private-law system.

For UAE civil law, fragmentation is particularly important because a single commercial relationship may simultaneously involve:

UAE federal law;

Emirate-level legislation;

UAE onshore courts;

DIFC Courts;

ADGM Courts;

foreign courts;

international arbitration;

foreign governing law;

international treaties and conventions;

different recognition and enforcement regimes.

Thus, a cross-border transaction can generate a chain such as:

Commercial Transaction → Multiple Jurisdictions → Different Laws → Different Courts → Different Procedural Rules → Conflicting Judgments → Recognition/Enforcement Problem

This is the central meaning of fragmentation.

2. Why UAE Is an Important Example

The UAE provides a particularly interesting illustration because it contains multiple legal spaces within one sovereign state.

A dispute may potentially involve:

UAE Onshore System

Federal legislation

Local Emirate legislation

Civil-law courts

Federal and local judicial structures

DIFC

Common-law influenced legal system

DIFC Courts

English/common-law concepts in specified areas

Special jurisdictional and enforcement legislation

ADGM

Separate common-law-based legal framework

ADGM Courts

English-law-derived principles in relevant areas

International Layer

Foreign courts

Foreign laws

Arbitration

International conventions

Cross-border enforcement

Therefore, UAE legal pluralism is not necessarily legal inconsistency. It is a structured form of jurisdictional and normative differentiation.

3. Fragmentation Versus Legal Pluralism

These concepts should be distinguished.

Legal pluralism

Means that multiple legal regimes legitimately operate within the same broader legal environment.

Fragmentation

Emphasises the possibility that those regimes:

use different concepts;

apply different procedures;

reach different conclusions;

recognise different jurisdictional boundaries;

apply different conflict-of-law rules.

Example

A contract might be:

governed by English law;

subject to DIFC jurisdiction;

performed partly in Dubai;

connected to an entity registered in another Emirate;

secured by assets in the UAE;

and ultimately enforced against assets in another country.

There is no single legal system capable of answering every question automatically.

4. Fragmentation of Substantive Law

The first level of fragmentation concerns which substantive law applies.

For example, a dispute may require separate answers concerning:

contract;

property;

corporate authority;

tort;

insolvency;

evidence;

limitation;

public policy.

Different laws may govern different questions.

This produces a phenomenon sometimes described as:

dépeçage — applying different legal systems to different aspects of the same dispute.

5. Fragmentation of Procedural Law

The second level concerns procedure.

A dispute may be substantively governed by UAE law while being procedurally determined under the rules of another forum.

Important procedural differences may concern:

disclosure;

expert evidence;

witness evidence;

privilege;

interim injunctions;

limitation;

appeals;

costs;

service;

enforcement.

Therefore:

Applicable substantive law ≠ Procedural law of the forum

This is a fundamental principle of private international law.

6. Fragmentation of Jurisdiction

Jurisdictional fragmentation occurs when more than one court can plausibly claim authority.

For example:

Dubai Courts ↔ DIFC Courts ↔ Foreign Court

A claimant may argue that several jurisdictions have connections with the dispute.

The legal system must then determine:

whether jurisdiction exists;

whether another forum is more appropriate;

whether proceedings should be stayed;

whether another judgment must be recognised;

whether an anti-suit injunction is available.

7. Case Law 1 — Protiviti v Al-Mojil

Protiviti Member Firm (Middle East) Ltd v Mohammad Bin Hamad Abdul-Karim Al-Mojil [2016] DIFC CA 003

This is one of the leading DIFC authorities demonstrating fragmentation between the DIFC legal system and foreign legal systems.

The Court of Appeal confirmed that the DIFC Courts can apply forum non conveniens principles when the competing forum is outside the UAE. It adopted the Spiliada framework, under which a defendant must demonstrate that another available forum is clearly or distinctly more appropriate. (DIFC Courts)

Principle

The existence of DIFC jurisdiction does not necessarily mean that the DIFC Court must determine every international dispute.

Relevance to fragmentation

It demonstrates that:

DIFC jurisdiction + foreign jurisdiction = competing legal systems requiring coordination.

8. Case Law 2 — KBC Aldini Capital v Baazov

KBC Aldini Capital Ltd v Baazov & Others [2017] DIFC CFI 002

The Court applied the two-stage forum non conveniens test.

The first stage asks whether another available forum is clearly more appropriate, considering factors including:

location of parties;

witnesses;

governing law;

convenience;

expense;

disclosure.

The second stage asks whether justice nevertheless requires the DIFC proceedings to continue. (DIFC Courts)

Principle

Fragmentation does not mean that every jurisdiction is equally appropriate.

Importance

The case illustrates the judicial mechanism for managing competing legal systems.

9. Case Law 3 — Barclays Bank v Al Khaili

Barclays Bank PLC v Hamad Suhail O. Al Khaili & Ibrahim Daoud Jaffal [2021] DIFC CA 003

This case is particularly important because it involved a judgment of the Abu Dhabi Courts and proceedings in the DIFC.

The Court considered the effect of a final judgment rendered by another UAE court and the relationship between:

DIFC jurisdiction;

UAE onshore courts;

recognition principles;

exclusive jurisdiction agreements;

the DIFC's own conflict-of-laws rules.

The Court emphasised that the UAE Civil Procedure Law does not simply apply inside the DIFC and that DIFC jurisdiction is determined by its own statutory framework. (DIFC Courts)

Principle

Even within one sovereign state, different judicial systems can possess distinct jurisdictional and procedural frameworks.

Importance

This is perhaps one of the clearest illustrations of intra-state legal fragmentation.

10. Case Law 4 — Lural v Listran

Lural v Listran & Lokhan [2021] DIFC CA 003

The Court considered the recognition and enforcement of judgments from another jurisdiction.

It held that, in the absence of specific statutory guidance, the DIFC's legal framework could lead to the application of English/common-law conflict-of-laws principles concerning recognition of foreign judgments.

The Court rejected the proposition that the DIFC Courts must automatically treat every judgment from another jurisdiction as binding. (DIFC Courts)

Principle

A judgment generated by one legal system does not automatically possess identical legal effect in another.

Fragmentation formula

Foreign Judgment → Recognition Rules → Public Policy/Conflict Rules → Enforcement

11. Case Law 5 — Tavira Securities v Re Point Ventures

Tavira Securities Ltd v Re Point Ventures FZCO & Others [2017] DIFC CFI 026

This case is important for understanding the relationship between jurisdiction and forum shopping.

The Court considered concerns that jurisdiction might arise retrospectively through a party establishing a DIFC connection after the events giving rise to the dispute.

The judgment identified the potential problems of:

unpredictable jurisdiction;

defeating parties' legitimate expectations;

retrospective jurisdiction;

artificial forum shopping;

lack of transparency. (DIFC Courts)

Principle

Legal fragmentation becomes problematic where parties can artificially manufacture jurisdiction after the underlying dispute has already occurred.

Importance

It demonstrates why jurisdictional gateways must be interpreted carefully.

12. Case Law 6 — Sandra Holding v Al Saleh

Sandra Holding Ltd & Nuri Musaed Al Saleh v Fawzi Musaed Al Saleh & Others [2023] DIFC CA 003

The Court considered the limits of DIFC jurisdiction in relation to enforcement of foreign judgments.

It stressed that jurisdiction over enforcement should not be expanded beyond what the legislation provides. In particular, the Court considered whether a person who was not a party to the foreign judgment could nevertheless be subjected to the DIFC enforcement jurisdiction. (DIFC Courts)

Principle

Jurisdiction must be grounded in the applicable statutory framework.

Relevance

Fragmentation creates a need for jurisdictional boundaries, otherwise one legal system could improperly extend its authority into another.

13. Case Law 7 — DIFC Investments Ltd v Dubai Islamic Bank

DIFC Investments Ltd v Dubai Islamic Bank [2022] DIFC CFI 024

The case involved proceedings connected with both the DIFC Courts and the onshore Dubai Courts.

The Court considered the principle that forum non conveniens does not ordinarily operate as between DIFC and UAE courts in the same manner as it does between the DIFC and a foreign court. Jurisdictional conflicts between UAE judicial systems can instead engage the UAE's Joint Judicial Committee framework. (DIFC Courts)

Principle

There are different mechanisms for managing:

DIFC ↔ Foreign Court

and

DIFC ↔ UAE Onshore Court

Importance

This is a central example of UAE's multi-layered legal architecture.

14. Case Law 8 — Banyan Tree v Meydan Group

Banyan Tree Corporate PTE Ltd v Meydan Group LLC [2013] DIFC ARB 003

The DIFC Court discussed the doctrine of appropriate forum/forum non conveniens and recognised its relevance where the alternative forum is foreign.

The judgment also reflected the distinction between foreign competing courts and local UAE courts. (DIFC Courts)

Principle

International jurisdictional fragmentation requires courts to determine which legal system should appropriately resolve the dispute.

15. The UAE's "Multiple Legal Orders" Problem

The UAE can therefore be represented as:

                    UAE                     │       ┌─────────────┼─────────────┐       │             │             │   Federal Law   Emirate Law   Special Zones       │             │             │       │         Dubai Courts   DIFC       │                         │       │                         ADGM       │   Onshore Courts

These systems interact through:

legislation;

jurisdictional rules;

conflict-of-laws principles;

recognition;

enforcement;

judicial cooperation;

arbitration;

constitutional/federal arrangements.

16. Fragmentation of Global Private Law

At the global level, the problem becomes even greater.

A multinational transaction may involve:

UAE law

English law

Singapore arbitration

Indian parties

Swiss bank

UAE assets

European data

The result is not one legal relationship but a network of legal relationships.

17. Fragmentation and Governing Law

A governing-law clause attempts to reduce fragmentation.

For example:

"This Agreement shall be governed by the laws of England and Wales."

The clause may determine substantive contractual issues.

But it does not necessarily determine:

jurisdiction;

procedural law;

enforcement law;

insolvency law;

property law governing local assets;

mandatory regulatory rules.

Therefore:

Choice of law ≠ choice of court ≠ choice of enforcement jurisdiction

18. Fragmentation and Public Policy

Recognition of a foreign judgment or award may be limited where recognition would conflict with fundamental legal principles of the enforcing jurisdiction.

This provides an important safety valve.

The basic structure is:

Foreign Decision

↓

Recognition Request

↓

Jurisdictional Requirements

↓

Procedural Requirements

↓

Public Policy

↓

Recognition/Enforcement

Thus, fragmentation is not necessarily eliminated by international judgments; it is managed through recognition mechanisms.

19. Fragmentation and Arbitration

Arbitration can reduce some forms of fragmentation by giving parties a common dispute-resolution mechanism.

For example:

UAE company + English company

may choose:

English governing law;

Singapore seat;

institutional arbitration.

But arbitration creates its own legal layers:

arbitration agreement;

law governing arbitration agreement;

procedural rules;

law of the seat;

substantive governing law;

law governing enforcement.

Therefore arbitration reorganises fragmentation rather than eliminating it.

20. Fragmentation and Foreign Judgments

A judgment may be valid in its originating jurisdiction but require separate recognition elsewhere.

For example:

English Judgment

↓

DIFC Recognition

↓

UAE Enforcement

↓

Execution against UAE assets

Each stage can introduce additional legal questions.

The Lural and Sandra Holding cases illustrate why the receiving court cannot simply assume that every foreign judgment automatically produces unlimited legal consequences.

21. Fragmentation and Digital Assets

Digital assets intensify the problem.

Consider:

Investor in India

↓

UAE virtual-asset platform

↓

Blockchain network

↓

Custodian in another country

↓

Bank account in Singapore

↓

Dispute involving a digital asset

Which law governs?

Potentially different laws may govern:

contractual relationship;

ownership;

custody;

transfer;

regulatory status;

insolvency;

cybersecurity;

data;

enforcement.

Thus:

Digital decentralisation → Territorial uncertainty → Legal fragmentation

22. Fragmentation and AI

AI systems create another form of fragmentation.

An AI service could involve:

UAE customer;

U.S. developer;

European cloud provider;

Singapore data centre;

Indian software engineers;

UAE deployment;

automated decision-making.

If the AI causes economic harm, the legal analysis may require separate answers concerning:

contract;

negligence/civil liability;

product/service responsibility;

data protection;

intellectual property;

cybersecurity;

consumer protection.

There may be no single global legal regime governing all of these questions.

23. Fragmentation and Legal Personality

Digital ecosystems also challenge traditional concepts of legal subjects.

For example:

DAO

may involve:

token holders;

developers;

protocol administrators;

smart contracts;

multisignature wallets;

custodians;

exchanges.

The technical system may be decentralised, but legal liability generally still requires identifying legally recognised persons or entities and connecting their conduct to applicable legal duties.

Thus:

Technical decentralisation ≠ legal decentralisation

24. Fragmentation and Civil Liability

Fragmentation becomes particularly difficult when harm crosses borders.

Consider:

UAE company → defective digital service → Indian consumer → European cloud infrastructure → financial loss in Singapore

Questions include:

Where did the wrongful act occur?

Where did damage occur?

Which law governs?

Which court has jurisdiction?

Can the defendant be served?

Can evidence be obtained?

Can the judgment be recognised?

Where are assets located?

The more jurisdictions involved, the greater the possibility of conflicting legal characterisations.

25. Fragmentation and Legal Characterisation

One jurisdiction may classify an issue as:

contractual

while another may classify substantially the same issue as:

tortious/civil liability.

This matters because different classification can produce different:

limitation periods;

jurisdictional rules;

governing laws;

remedies;

evidential requirements.

This is known as a characterisation problem in private international law.

26. Fragmentation and Limitation

Limitation periods can also fragment.

For example:

Forum A → 3-year limitation

Forum B → 6-year limitation

Forum C → special statutory period

The question then becomes whether limitation is treated as:

substantive; or

procedural.

The answer can determine which legal system's limitation rules apply.

27. Fragmentation and Evidence

Evidence is another major source of fragmentation.

Different jurisdictions may have radically different approaches to:

discovery/disclosure;

privilege;

expert evidence;

witness statements;

hearsay;

electronic records;

blockchain evidence;

AI-generated evidence.

A UAE dispute involving foreign evidence may therefore require cooperation between legal systems with very different evidentiary traditions.

28. Fragmentation and Enforcement

The ultimate weakness of fragmented legal systems is that winning the case and obtaining practical relief are different events.

The sequence is:

Claim

↓

Jurisdiction

↓

Judgment

↓

Recognition

↓

Enforcement

↓

Asset Recovery

A judgment without an effective enforcement route may have limited practical value.

29. Fragmentation Theory: The Four-Layer Model

A useful way to analyse UAE global litigation is:

Layer 1 — Normative fragmentation

Different substantive laws.

Layer 2 — Institutional fragmentation

Different courts and tribunals.

Layer 3 — Procedural fragmentation

Different procedural and evidential systems.

Layer 4 — Enforcement fragmentation

Different rules for recognition and execution.

Therefore:

Global Legal Fragmentation = Substantive + Institutional + Procedural + Enforcement Fragmentation

30. Does Fragmentation Mean Legal Chaos?

No.

Fragmentation does not necessarily mean that international private law is chaotic.

Legal systems have developed mechanisms to coordinate different regimes:

jurisdiction agreements;

choice-of-law clauses;

forum non conveniens;

lis pendens;

anti-suit injunctions;

arbitration;

recognition conventions;

enforcement legislation;

judicial cooperation;

public-policy exceptions.

The objective is not necessarily to eliminate every difference.

It is to manage the interaction between different legal systems.

31. UAE Approach to Managing Fragmentation

The UAE's legal architecture uses several mechanisms.

1. Jurisdictional gateways

They determine when a particular court may hear a dispute.

2. Choice-of-law rules

They determine which substantive law applies.

3. Forum non conveniens

Relevant particularly to foreign competing forums under DIFC jurisprudence.

4. Joint Judicial Committee

Important for certain jurisdictional conflicts between DIFC and Dubai courts.

5. Recognition and enforcement

Allows judgments and awards generated elsewhere to acquire legal effect subject to applicable requirements.

6. Arbitration

Provides a private international dispute-resolution mechanism.

32. Fragmentation and Forum Engineering

Fragmentation creates incentives for forum engineering.

A claimant may examine:

jurisdiction;

governing law;

limitation;

interim remedies;

disclosure;

damages;

costs;

appeal;

enforcement.

This does not mean every choice of forum is abusive.

There is a distinction between:

legitimate jurisdictional planning

and

artificial manipulation of jurisdiction.

The Tavira Securities judgment is particularly useful for understanding concerns about after-the-event jurisdictional engineering. (DIFC Courts)

33. Relationship With the New UAE Civil Transactions Law

The new Federal Decree-Law No. 25 of 2025, effective from 1 June 2026, provides the current federal civil-law framework.

Its conflict-of-laws provisions are particularly important for fragmentation because they address circumstances in which relationships contain international elements.

The new Code also preserves the importance of determining the relevant legal system before applying substantive civil-law rules.

This means that in a multinational dispute the court may have to conduct two separate inquiries:

First

Which legal system governs?

Second

What does that legal system provide?

That distinction is fundamental to fragmentation theory.

34. Important Case-Law Principles — Summary Table

35. Core Distinctions for Examination

Fragmentation ≠ conflict

Two legal systems can differ without actually producing conflicting judgments.

Fragmentation ≠ forum shopping

Fragmentation is a structural condition; forum shopping is a strategic response to that condition.

Governing law ≠ jurisdiction

The court hearing a case may apply foreign substantive law.

Jurisdiction ≠ enforcement

A court having jurisdiction does not automatically mean its judgment will be enforceable everywhere.

Recognition ≠ automatic acceptance

A foreign judgment normally has to satisfy the applicable recognition framework.

Legal pluralism ≠ legal uncertainty

Multiple legal systems can coexist through structured jurisdictional rules.

36. Practical Analytical Formula

For any UAE cross-border civil dispute, the following sequence is useful:

1. Identify the parties

↓

2. Identify every relevant jurisdiction

↓

3. Identify the contractual forum clause

↓

4. Identify the governing-law clause

↓

5. Determine jurisdiction

↓

6. Examine competing proceedings

↓

7. Apply conflict-of-laws rules

↓

8. Determine substantive law

↓

9. Obtain judgment/award

↓

10. Determine recognition

↓

11. Locate enforceable assets

↓

12. Execute the judgment/award

This is the practical methodology for managing fragmentation.

37. Conclusion

Fragmentation of global legal systems describes the reality that cross-border civil disputes are no longer necessarily governed by a single coherent legal order. The UAE provides a particularly important example because its legal environment combines federal civil law, Emirate-level courts, specialised financial free-zone courts, arbitration and international private-law mechanisms.

The DIFC cases demonstrate that courts attempt to manage fragmentation through:

jurisdictional gateways;

forum non conveniens;

choice-of-law principles;

recognition rules;

enforcement mechanisms;

judicial coordination;

respect for contractual jurisdiction clauses.

The most important conceptual lesson is:

Global civil law is increasingly a system of interaction between legal orders rather than a single universal legal system.

For UAE litigation, the practical problem is therefore not merely determining what the law says, but determining which legal system gets to say what the law is, which court can decide the dispute, and whether that decision can ultimately be recognised and enforced elsewhere.
