Civil Law and UAE: Historical Development of the UAE Civil Transactions Law

1. Introduction

The history of UAE civil law is closely connected with the country's transformation from a collection of emirates with diverse customary and Islamic legal practices into a modern federal state with a comprehensive codified private-law system.

The development can broadly be understood in five stages:

Pre-federal period — Islamic jurisprudence, local custom and tribal/commercial practice.

Formation of the UAE in 1971 — constitutional federalisation and development of unified legislation.

Federal Civil Transactions Law of 1985 — Federal Law No. 5 of 1985 created the principal UAE Civil Code.

Four decades of judicial development — Federal Supreme Court and Cassation Courts progressively interpreted the Code.

2025–2026 reform — Federal Decree-Law No. 25 of 2025 repealed the 1985 Code and introduced the new Civil Transactions Law, effective 1 June 2026. (UAE Legislation)

The historical significance of the UAE Civil Transactions Law is therefore not simply that the UAE enacted a civil code. It is that the Code became the central bridge between Islamic legal principles, Arab civil-law codification, commercial practice and modern international economic activity.

2. Pre-1971 Legal Background

Before the establishment of the UAE federation in 1971, there was no single federal Civil Code.

Private relationships were governed through a combination of:

Islamic jurisprudence;

local customs;

tribal practices;

commercial customs;

principles applied by local rulers;

limited legislation;

contractual arrangements.

The legal environment was therefore considerably less centralised than the modern UAE system.

Islamic jurisprudence was particularly important in areas such as:

contracts;

property;

inheritance;

family relations;

compensation;

obligations;

commercial dealings.

Custom also had an important practical role.

3. Influence of Islamic Jurisprudence

The UAE Civil Transactions Law should not be understood as a complete break from Islamic law.

Instead, codification incorporated concepts that have deep roots in Islamic jurisprudence, including:

good faith;

prohibition of harm;

protection of legitimate rights;

contractual obligations;

compensation;

unjust enrichment;

custom;

public order;

fairness.

The Civil Code's structure also reflects the broader Arab civil-law tradition in which Islamic jurisprudence interacts with modern statutory codification.

Comparative scholarship identifies the Ottoman Majalla and the Egyptian Civil Code as two major historical models in the development of modern Middle Eastern civil-law codification. (OUP Academic)

4. The Majalla as a Historical Influence

The Majalla al-Ahkam al-Adliyya, or Ottoman Majalla, was an important nineteenth-century attempt to codify principles of Islamic jurisprudence, particularly Hanafi jurisprudence.

Although the UAE did not simply adopt the Majalla as its Civil Code, the wider Arab legal environment was strongly influenced by it.

The Majalla demonstrated that Islamic legal principles could be:

organised into statutory articles;

systematically classified;

applied by courts;

used to regulate commercial and civil transactions.

This was an important intellectual precursor to later Arab civil codes.

5. Egyptian Civil Code and Arab Codification

Another major influence was the Egyptian Civil Code of 1948, associated with the work of the Egyptian jurist Abd al-Razzaq al-Sanhuri.

The Sanhuri model attempted to combine:

European continental civil-law concepts;

Islamic jurisprudence;

Arab legal traditions;

judicial principles;

modern contractual theory.

The UAE Civil Transactions Law belongs to this broader Arab civil-law tradition.

Modern scholarship specifically identifies the Egyptian Civil Code and the Sanhuri codification movement as significant influences on Middle Eastern civil-law systems, including the UAE. (IJLMH)

6. Establishment of the UAE in 1971

The establishment of the United Arab Emirates in 1971 created the constitutional foundation for federal legislation.

The new federation required legal systems capable of regulating:

inter-emirate commerce;

property;

contracts;

banking;

companies;

construction;

employment;

investment;

civil liability.

The Constitution created a federal legislative framework while preserving important areas of Emirate-level authority.

This gradually encouraged the development of unified federal private-law legislation.

7. The Road Toward a Federal Civil Code

During the early federal period, UAE law consisted of a mixture of:

pre-existing local legislation;

federal legislation;

Islamic legal principles;

customary rules;

judicial interpretation.

As the UAE economy expanded, this fragmented structure became increasingly unsuitable for a rapidly developing commercial economy.

There was growing need for:

uniform rules;

predictable contracts;

defined property rights;

standardised liability;

codified remedies;

commercial certainty.

The response was the creation of a comprehensive federal Civil Transactions Law.

8. Federal Law No. 5 of 1985

The decisive historical event was the enactment of:

Federal Law No. 5 of 1985 Promulgating the Civil Transactions Law of the United Arab Emirates.

It became the principal source of general UAE private law for approximately four decades.

The Code regulated subjects including:

obligations;

contracts;

property;

ownership;

sale;

lease;

agency;

guarantees;

tort liability;

damages;

unjust enrichment;

conflict of laws;

named contracts.

Its importance cannot be overstated.

It transformed UAE private law from a developing collection of rules into a comprehensive codified system.

9. Structure of the 1985 Civil Transactions Law

The 1985 Code was extremely extensive.

It included:

Preliminary provisions

Including:

application of law;

conflict of laws;

interpretation;

public order.

Obligations

Including:

contracts;

unilateral acts;

tort;

unjust enrichment;

compensation.

Property

Including:

ownership;

possession;

usufruct;

real rights.

Specific contracts

Including:

sale;

lease;

agency;

construction;

partnership;

guarantee;

loan;

deposit;

other nominate contracts.

This broad structure made the Code the foundation of UAE private law.

10. Article 1 and the Role of Islamic Principles

One of the historically important characteristics of the UAE Civil Code was its methodology for dealing with situations where statutory provisions did not directly resolve a dispute.

The traditional structure placed emphasis on:

statutory provisions;

applicable principles of Islamic jurisprudence;

customary rules;

principles of justice and equity in appropriate circumstances.

This illustrates the hybrid character of UAE civil law:

Codified legislation + Islamic jurisprudence + custom + judicial interpretation.

11. Development Through Judicial Interpretation

The 1985 Code was not static.

Its broad provisions required courts to interpret concepts such as:

good faith;

abuse of rights;

causation;

damage;

contractual interpretation;

force majeure;

hardship;

unjust enrichment;

public policy.

The Federal Supreme Court and the Courts of Cassation consequently became major contributors to the practical development of UAE civil law.

The result was a distinction between:

Civil Code as written law

and

Civil Code as interpreted by the courts.

12. Case Law 1 — Dubai Court of Cassation, Appeal No. 581 of 2003

This case concerned incorporation of FIDIC conditions into a construction contract and the resulting arbitration agreement.

Principle

The Dubai Court of Cassation accepted that contractual terms incorporated by reference can have legal effect where the requirements for incorporation are satisfied.

Historical significance

It illustrates how the 1985 Civil Code adapted to modern construction and international commercial practices.

The Civil Code was not restricted to traditional transactions.

It became capable of supporting:

international construction contracts;

standard-form contracts;

arbitration;

sophisticated commercial relationships.

This case is therefore an example of the Code's adaptation to global commerce. (Kluwer Arbitration Blog)

13. Case Law 2 — Abu Dhabi Court of Cassation, Case No. 16 of 2010

This case is important concerning Article 249 and exceptional circumstances.

The Court explained the principle that parties generally cannot unilaterally revoke or amend their contractual obligations unless the circumstances fall within the statutory doctrine of exceptional circumstances and the requirements for judicial intervention are satisfied.

Principle

Contractual certainty is the starting point.

Judicial adjustment is exceptional and requires satisfaction of the statutory requirements.

Historical significance

The decision demonstrates how courts transformed the general wording of Article 249 into an operational doctrine of hardship/exceptional circumstances.

(Chambers)

14. Case Law 3 — Abu Dhabi Court of Cassation, Petitions Nos. 293 and 313 of 2013

These proceedings concerned an arbitration dispute involving Article 249 of the Civil Transactions Law.

The claimant argued that an arbitral award should have reduced its obligation under the exceptional-circumstances doctrine.

Principle

Article 249 does not operate automatically merely because performance has become difficult.

The statutory requirements and judicial assessment remain important.

Historical significance

The case illustrates the interaction between:

Civil Code;

hardship;

arbitration;

judicial review.

It demonstrates how the 1985 Code increasingly operated within an international dispute-resolution environment. (JusMundi)

15. Case Law 4 — Abu Dhabi Court of Cassation, Case No. 735/2012

This case is frequently discussed in relation to force majeure and hardship in construction contracts.

Principle

Ordinary commercial risks and increases in construction costs do not automatically constitute force majeure.

The court must distinguish:

ordinary commercial risk;

impossibility;

exceptional circumstances;

excessive onerousness.

Historical significance

The case demonstrates the sophisticated judicial interpretation of Articles 249 and 273 in modern construction disputes.

It shows how a provision originally drafted in the 1985 Code was adapted to complex FIDIC and construction litigation. (Bspace)

16. Case Law 5 — Dubai Court of Cassation, Case No. 713/2017 Commercial Cassation

This case involved construction-related obligations under the Civil Transactions Law.

Principle

The courts applied the Civil Code's contractual and construction provisions to determine responsibility for loss arising from construction activities.

Historical significance

It demonstrates how the Civil Code became an important source of law for sophisticated construction disputes involving:

contractors;

developers;

subcontractors;

engineers;

defects;

loss;

causation.

The decision is cited in academic treatment of UAE construction liability under the 1985 Code. (studylib.net)

17. Case Law 6 — Dubai Court of Cassation, Case No. 266/2008

This construction dispute concerned delay, defects and responsibility for delay.

The court considered the parties' respective conduct and the role of third-party/subcontractor delay.

Principle

Liability and delay must be assessed by reference to causation and the actual circumstances rather than mechanically attributing all delay to one party.

Historical significance

The decision illustrates the Civil Code's development through construction litigation and its application of general principles concerning:

causation;

contractual liability;

damages;

concurrent responsibility.

It demonstrates how broad Code provisions were adapted to complex modern projects. (Грађевински факултет)

18. Case Law 7 — Dubai Court of Cassation, Judgment No. 288 of 2025

This is an important late-stage case under the 1985 Code.

The Court considered good faith under Article 246 and the relationship between contractual terms and the parties' conduct.

Principle

Contractual rights must be exercised consistently with good faith.

The contractual relationship extends beyond the literal terms to obligations arising from:

law;

custom;

nature of the transaction.

Historical significance

The decision illustrates how, toward the end of the 1985 Code's life, judicial interpretation had developed Article 246 into a significant general principle governing commercial relationships. (DIFC Courts)

19. Case Law 8 — Dubai Court of Cassation, Judgment No. 503 of 2025

This decision concerned contractual enforcement and the principle of pacta sunt servanda.

Principle

A valid contract must generally be performed according to its terms and in good faith, subject to statutory limitations.

Historical significance

The decision represents the mature stage of the 1985 Civil Code.

By 2025, courts had developed a sophisticated balance between:

contractual certainty;

good faith;

statutory intervention;

public order.

(KH Legal)

20. Development of the Good-Faith Doctrine

One of the clearest examples of historical judicial development is Article 246.

The former Article 246 provided:

A contract must be performed according to its contents and consistently with good faith.

It also extended contractual obligations to matters arising from:

law;

custom;

the nature of the transaction.

(UAE Legal Notes)

Over four decades, courts transformed this short provision into a broad principle affecting:

contractual performance;

interpretation;

cooperation;

exercise of contractual rights;

prevention of abuse;

commercial conduct.

The jurisprudence surrounding Article 246 therefore became an important part of UAE contract law.

21. Development of the Abuse-of-Rights Doctrine

Another major historical feature was Article 106.

It restricted abusive exercise of rights.

This principle allowed courts to consider whether a formally available legal right was being exercised:

intentionally to harm another;

disproportionately;

contrary to established custom;

without legitimate interest.

The doctrine helped prevent the Civil Code from becoming a purely formalistic system.

It introduced an important corrective:

A legal right must not necessarily be exercised in an abusive manner merely because its holder technically possesses it.

22. Development of the Hardship Doctrine

Article 249 became internationally notable.

It allowed judicial intervention where:

exceptional circumstances occurred;

the circumstances were unforeseeable;

they were of a public nature;

performance remained possible;

performance became oppressive;

serious loss threatened the debtor.

The judge could reduce the oppressive obligation to a reasonable level after balancing the interests of the parties.

(UAE Legal Notes)

This made UAE civil law distinctive compared with common-law systems that traditionally treated contractual certainty differently.

23. Development of Force Majeure

Article 273 separately developed the doctrine of force majeure.

The historical distinction became:

Force majeure

Performance becomes impossible or legally prevented.

Hardship

Performance remains possible but becomes excessively burdensome.

This distinction became particularly important during:

construction disputes;

economic crises;

supply disruptions;

COVID-19;

government restrictions.

The new Code preserves this general architecture while modifying some aspects of the remedies. (Afridi & Angell)

24. Development of Civil Liability

The 1985 Code also created a structured framework for tort liability.

A central principle was that a person causing harm to another could be required to compensate the injured party.

Judicial development progressively addressed:

causation;

contributory fault;

third-party responsibility;

professional liability;

construction defects;

medical liability;

property damage;

economic loss.

This allowed the Code to adapt to increasingly complex economic activity.

25. Development of Construction Law Through the Civil Code

Construction became one of the most important areas of UAE civil-law development.

The rapid expansion of:

Dubai;

Abu Dhabi;

infrastructure;

tourism;

real estate;

airports;

ports;

energy projects;

created thousands of construction disputes.

The Civil Code therefore became a major foundation for determining:

contractor responsibility;

employer responsibility;

defects;

delay;

payment;

termination;

damages;

force majeure;

subcontracting.

The jurisprudence surrounding Articles 246, 247, 249, 273, 287 and the construction provisions significantly expanded the practical importance of the Code.

26. Development of Commercial Civil Law

The UAE Civil Code did not remain limited to private individuals.

It became heavily used in:

banking;

finance;

insurance;

construction;

real estate;

corporate transactions;

international commerce.

This occurred despite the parallel development of specialised commercial legislation.

The relationship became:

Civil Code = general private-law principles

Commercial legislation = specialised commercial rules

The two systems increasingly operated together.

27. Development of Private International Law

The 1985 Civil Code also contained a dedicated conflict-of-laws section.

Academic analysis identifies Articles 10–28 of the 1985 Code as the statutory foundation of UAE private international law. (OUP Academic)

These provisions addressed matters such as:

nationality;

domicile;

personal status;

contractual obligations;

tort;

property;

foreign law;

public policy.

This was historically important because it enabled UAE courts to deal systematically with international transactions.

28. Development of Arbitration

The 1985 Civil Code operated during the period in which arbitration became increasingly important in UAE commercial disputes.

Construction and international commercial contracts frequently included:

ICC clauses;

FIDIC arbitration clauses;

institutional arbitration;

ad hoc arbitration.

The Civil Code supplied the underlying substantive law, while later arbitration legislation supplied the procedural framework.

This eventually culminated in the UAE Federal Arbitration Law No. 6 of 2018.

29. Development of Electronic and Modern Transactions

The 1985 Code was enacted before:

widespread internet commerce;

electronic signatures;

smartphones;

blockchain;

cryptocurrencies;

artificial intelligence.

Nevertheless, its general principles were sufficiently broad to interact with later legislation concerning:

electronic transactions;

digital evidence;

data;

e-commerce.

This demonstrates one of the strengths of codification:

Broad principles can survive technological change even when the original Code predates the technology.

30. The Need for Reform

By the 2020s, the UAE economy had changed dramatically.

The country had become a major centre for:

international finance;

logistics;

real estate;

technology;

e-commerce;

investment;

arbitration;

multinational corporations.

At the same time, numerous specialised statutes had been introduced.

This created potential overlap between:

Civil Transactions Law;

Commercial Transactions Law;

Companies legislation;

Arbitration Law;

Evidence Law;

Consumer Protection Law;

Personal Data Protection Law;

insolvency legislation;

labour legislation.

The Government therefore considered a comprehensive modernisation of the Civil Code.

31. Federal Decree-Law No. 25 of 2025

The decisive reform came with:

Federal Decree-Law No. 25 of 2025 Promulgating the Civil Transactions Law.

The legislation expressly repealed:

Federal Law No. 5 of 1985.

Article 3 of the 2025 Decree-Law provides that the new law enters into force on 1 June 2026. (UAE Legislation)

Thus, as of September 2026, the 1985 Code is no longer the current Civil Transactions Law.

32. Why the 2025 Code Was Introduced

The new Code seeks to:

modernise UAE civil law;

improve legal certainty;

eliminate unnecessary duplication;

integrate civil law with specialised legislation;

clarify contractual principles;

accommodate contemporary transactions;

strengthen legislative coherence.

The UAE Government has expressly described the reform as an effort to create an integrated legal framework and eliminate legislative duplication. (UAE Legislation)

33. Important Changes in the New Code

The new Code preserves many established principles while reorganising and updating them.

For example:

The renumbering is important when reading older UAE judgments.

For example, a case discussing Article 246 under the 1985 Code may correspond conceptually to Article 221 under the new Code. (Kayrouz & Associates)

34. New Treatment of Pre-Contractual Conduct

One important development is the express treatment of pre-contractual negotiations.

The new Code introduces provisions dealing with:

good faith during negotiations;

disclosure;

wrongful conduct during negotiations;

consequences of unlawful withdrawal or misconduct.

This is a significant development because the 1985 Code was more heavily focused on contractual obligations after formation.

The reform therefore extends civil-law protection into the pre-contractual stage. (IJLMH)

35. New Treatment of Hardship

The old Article 249 primarily empowered the court to reduce an oppressive obligation.

The new Article 224 retains the hardship concept but expands the available judicial response, including the possibility of rescission in appropriate circumstances. (Chambers Practice Guides)

This is an important evolution.

The historical progression is:

1985: judicial adjustment of oppressive obligation

↓

2026: adjustment plus expanded judicial remedial flexibility

36. Continuity Between the Old and New Codes

The 2025 reform should not be understood as a complete rejection of the 1985 Code.

There is substantial continuity.

The new Code retains important principles involving:

contractual binding force;

good faith;

abuse of rights;

compensation;

causation;

hardship;

force majeure;

property;

unjust enrichment.

Thus:

The new Code is evolutionary as well as reformative.

37. Historical Significance of UAE Case Law

The historical development of the Civil Transactions Law cannot be understood solely by reading legislation.

Judicial decisions have:

interpreted broad statutory language;

developed tests for hardship;

clarified good faith;

developed construction liability;

interpreted contractual clauses;

addressed international contracts;

applied the Code to modern commercial activity.

Consequently:

UAE civil law developed through the interaction of legislation and judicial interpretation.

38. Timeline of Historical Development

39. Six Important Historical Case-Law Lessons

These cases should be understood as illustrations of the development of judicial principles under the former 1985 Code. Since the 2025 Code took effect on 1 June 2026, the precise statutory provision applicable to a current dispute must be checked under the new Code and its transitional provisions.

40. Major Historical Characteristics of UAE Civil Law

1. Islamic foundation

Islamic jurisprudential concepts remain an important historical foundation.

2. Civil-law codification

The UAE adopted systematic statutory codification.

3. Arab legal influence

The Majalla and modern Arab civil codes influenced the intellectual environment.

4. Judicial development

Courts gave practical meaning to broad statutory concepts.

5. Commercial adaptation

The Code adapted to rapidly developing business activity.

6. Internationalisation

The Code developed rules for international contracts and foreign elements.

7. Modernisation

The 2025 Code updates the system for contemporary economic and technological conditions.

41. Importance of the 1985 Code

The 1985 Civil Transactions Law performed several historic functions.

It:

unified important private-law rules;

increased predictability;

reduced dependence on fragmented local practices;

provided a framework for modern contracts;

facilitated commercial development;

gave courts structured legal principles;

supported international investment;

established an extensive body of jurisprudence.

For approximately four decades, it was one of the foundational pieces of UAE legislation.

42. Importance of the 2025–2026 Reform

The new Civil Transactions Law represents the next stage of this historical development.

The movement can therefore be summarised as:

Customary and Islamic principles

↓

Federalisation after 1971

↓

Comprehensive codification in 1985

↓

Four decades of judicial development

↓

Modernisation and legislative integration in 2025–2026

This is the most useful historical framework for understanding UAE civil law.

43. Conclusion

The historical development of the UAE Civil Transactions Law is a story of legal codification, judicial development and modernisation.

The original legal environment was shaped by:

Islamic jurisprudence;

custom;

local practice.

After the formation of the UAE federation in 1971, the need for a unified private-law system became increasingly important.

The enactment of Federal Law No. 5 of 1985 represented the decisive codification stage. For four decades, the Code provided the principal framework for:

contracts;

property;

civil liability;

damages;

guarantees;

construction;

commercial relationships;

international private law.

Judicial decisions progressively developed broad concepts such as good faith, abuse of rights, hardship, force majeure, causation and contractual interpretation.

The next major stage arrived with Federal Decree-Law No. 25 of 2025, which repealed the 1985 Code and entered into force on 1 June 2026. (UAE Legislation)

The historical development can therefore be remembered as:

Islamic jurisprudence → local custom → federalisation → 1985 codification → judicial development → commercial/international expansion → 2025 reform → 2026 modern Civil Transactions Law.

Exam Revision Points

UAE Civil Law has roots in Islamic jurisprudence and customary law.

The Majalla influenced the wider Arab codification tradition.

The Egyptian Civil Code/Sanhuri tradition was an important comparative influence.

The UAE federation was established in 1971.

Federal Law No. 5 of 1985 created the principal UAE Civil Transactions Law.

The 1985 Code governed UAE private law for approximately four decades.

UAE courts significantly developed Articles concerning good faith, abuse of rights, hardship and force majeure.

Construction and commercial litigation played a major role in judicial development.

Federal Decree-Law No. 25 of 2025 repealed the 1985 Code.

The new Civil Transactions Law became effective on 1 June 2026.

Many older cases remain historically valuable, but their statutory provisions must be mapped to the new Code when dealing with current disputes.

The new Code represents continuity plus modernisation, rather than a complete break with the historical UAE civil-law tradition.
