1. Introduction

UAE civil law is built around a codified civil-law system, but it operates alongside specialised legislation covering companies, arbitration, evidence, consumer protection, employment, data protection, banking, insurance, real estate and other fields.

A major current development is that Federal Decree-Law No. 25 of 2025 promulgating the new Civil Transactions Law entered into force on 1 June 2026 and repealed Federal Law No. 5 of 1985. The new law is intended to reorganise the general foundations of civil rights and obligations, improve clarity and reduce duplication with special legislation.

Therefore, for studying UAE civil law today, it is important to understand both:

• the current 2026 Civil Transactions Law;
• older case law developed under the former 1985 Civil Code, where its principles remain relevant only insofar as they correspond to the current law and applicable transitional rules;
• specialised UAE legislation;
• and, where useful, DIFC/ADGM jurisprudence, clearly distinguished from mainland UAE precedent.

3. Legal Personality and Capacity

Meaning

Legal personality means the ability of a person or legal entity to possess rights and bear obligations.

Civil law distinguishes between:

• natural persons;
• companies and other legal entities;
• contractual capacity;
• capacity to own property;
• capacity to sue or be sued.

Importance

Capacity becomes particularly important where a party argues that:

• it lacked authority;
• it was legally incapable of contracting;
• an agent exceeded authority;
• a company representative acted outside corporate powers.

Example

If an individual signs a major commercial agreement without the required legal authority, the court may need to determine whether the agreement binds the individual, the company, or neither.

4. Sources of Civil Obligations

A civil obligation may arise from several sources, including:

• contract;
• unilateral acts;
• harmful acts/torts;
• unjust enrichment;
• legislation;
• other legally recognised sources.

The fundamental question is:

Why is one person legally required to give, do, refrain from doing, or compensate another?

This concept is the foundation for almost every civil claim.

5. Contract Formation

A contract generally depends upon legally effective agreement between parties concerning its essential elements.

Important questions include:

• Was there an offer?
• Was there acceptance?
• Did the parties have capacity?
• Was consent genuine?
• Was the subject matter lawful?
• Was the purpose legally permissible?
• Were formalities required?

Contract formation should always be distinguished from contract performance.

6. Consent and Defects of Consent

Consent may be affected by circumstances such as:

• mistake;
• fraud/misrepresentation;
• coercion or duress;
• exploitation of legally recognised circumstances.

A court may have to determine whether the defect was sufficiently serious to affect the validity or enforceability of the transaction.

Exam point

Defective consent attacks the quality of agreement itself.

This differs from breach of contract, where a valid agreement exists but one party subsequently fails to perform.

7. Mistake

Mistake occurs where a party forms an incorrect understanding concerning an important aspect of the transaction.

The important legal question is not simply:

“Was one party mistaken?”

It is:

Was the mistake legally significant enough to affect the transaction under the applicable law?

Relevant considerations may include:

• nature of the subject matter;
• identity;
• essential characteristics;
• contractual allocation of risk;
• whether the other party knew or should have known about the mistake.

8. Fraud and Misrepresentation

Fraud involves intentional deception, while misrepresentation concerns a false or misleading representation that materially influences a transaction.

Possible consequences can include:

• avoidance or cancellation where legally available;
• restitution;
• damages;
• other appropriate remedies.

The evidentiary burden is important because a serious allegation of fraud generally requires convincing evidence.

9. Freedom of Contract

Freedom of contract means that parties generally have significant autonomy to determine:

• whether to contract;
• with whom to contract;
• contractual terms;
• price;
• allocation of risk;
• dispute-resolution mechanism.

However, contractual freedom is not unlimited.

It operates subject to:

• mandatory legislation;
• public policy;
• public order;
• good faith;
• rights of third parties;
• sector-specific regulation.

Simple formula

Freedom of contract ≠ freedom to contract outside mandatory law.

10. Good Faith

Good faith is one of the most important civil-law concepts.

It influences:

• contractual performance;
• interpretation;
• exercise of contractual rights;
• negotiations;
• disclosure;
• prevention of deceptive conduct;
• avoidance of abusive conduct.

Good faith does not necessarily mean that every party must maximise the interests of the other party. Rather, it operates as a legal standard against dishonest, abusive or legally unacceptable conduct.

11. Contractual Interpretation

Courts must determine what the parties' agreement legally means.

Interpretation can involve:

• wording;
• context;
• purpose;
• contractual structure;
• relationship between clauses;
• commercial circumstances where legally relevant.

The DIFC Courts have repeatedly emphasised that contractual interpretation is governed by the applicable statutory framework rather than by judicial preference.

In Ashok Kumar Goel v Credit Suisse [2021] DIFC CA 002, the DIFC Court of Appeal dealt with guarantees and jurisdiction, demonstrating the importance of identifying the applicable legal framework before deciding contractual questions.

Important: this is a DIFC authority, not a binding mainland UAE Supreme Court precedent.

12. Performance of Contracts

Once a valid contract exists, parties must perform their obligations according to:

• contractual terms;
• applicable legislation;
• good faith;
• legally recognised standards of performance.

Performance questions include:

• Was payment made?
• Was delivery completed?
• Was the required quality achieved?
• Was time of performance essential?
• Were contractual conditions satisfied?

13. Breach of Contract

A breach occurs where a party fails to perform an obligation as required.

Common breaches include:

• non-payment;
• late performance;
• defective performance;
• failure to deliver;
• repudiation;
• violation of confidentiality;
• breach of warranties.

The legal consequences depend upon:

1. seriousness of breach;
2. contractual provisions;
3. applicable statutory remedies;
4. causation;
5. actual loss.

14. Termination and Rescission

Termination brings contractual obligations to an end, subject to the applicable legal framework and contractual terms.

A court may have to distinguish between:

• contractual termination;
• statutory termination;
• judicial termination;
• cancellation/avoidance arising from defective consent;
• termination for fundamental breach.

In DIFC Investments LLC v Mohammed Akbar Mohammed Zia [2017] DIFC CFI 001, the DIFC Court held that a series of property contracts had been terminated following non-payment under the applicable DIFC Contract Law. The Court of Appeal subsequently dismissed the appeal.

This case illustrates the distinction between formation of a contract and consequences of subsequent non-performance.

15. Damages and Compensation

Compensation is a central civil-law remedy.

The basic objective is generally to address legally recognised loss resulting from another party's legally attributable conduct.

Possible categories include:

• actual financial loss;
• lost profits where legally recoverable;
• property damage;
• expenses;
• personal injury;
• moral/non-economic damage where recognised.

The claimant normally must establish the necessary connection between the wrongful conduct and claimed loss.

16. Causation

Causation asks:

Did the defendant's conduct legally cause the claimant's damage?

There can be several factual events between conduct and damage.

Therefore, courts distinguish between:

• factual causation;
• legal causation;
• foreseeable/consequential loss where relevant;
• independent intervening causes.

Example

A contractor negligently damages a building. The owner later incurs repair costs and business interruption losses.

The court must determine which losses were sufficiently connected with the contractor's breach.

17. Moral and Non-Monetary Damage

Civil law is not limited to physical property and direct financial loss.

Depending on the applicable legal framework, compensation may address legally recognised non-economic injury such as:

• emotional suffering;
• injury to reputation;
• dignity;
• personal rights;
• psychological suffering associated with a legally compensable wrong.

The central problem is valuation: how can a non-monetary injury be expressed in monetary terms?

This is particularly important in modern civil litigation involving:

• privacy;
• defamation;
• data misuse;
• personal injury;
• digital identity;
• AI-generated harmful content.

18. Unjust Enrichment

Unjust enrichment concerns situations where:

One person obtains a benefit at another's expense without a sufficient legal basis for retaining that benefit.

Typical examples include:

• mistaken payment;
• receiving money without contractual entitlement;
• reversal of a failed transaction;
• benefits remaining after a contract is invalidated.

Unjust enrichment should be distinguished from contractual damages because the focus is often on the unjust benefit, rather than simply breach of an agreement.

19. Abuse of Rights

A legal right is not necessarily unlimited merely because it exists.

Abuse-of-right principles can become relevant where a person exercises a right in an illegitimate or legally unacceptable manner.

Examples may include:

• causing disproportionate harm;
• pursuing a right for an illegitimate purpose;
• using a legal power contrary to its intended function;
• interfering unjustifiably with another person's rights.

This principle is particularly important because it prevents civil law from treating formal legal rights as absolute in every circumstance.

20. Tort and Civil Wrong

A civil wrong can arise independently of contract.

Typical elements include:

1. legally relevant conduct;
2. fault or another basis of liability;
3. damage;
4. causation.

Examples:

• negligent driving;
• professional negligence;
• property damage;
• defamation;
• unlawful interference;
• harmful digital conduct.

Contract vs tort

21. Force Majeure

Force majeure concerns extraordinary circumstances that interfere with contractual performance.

Examples may include:

• natural disasters;
• war;
• government restrictions;
• extraordinary external events.

The crucial question is not merely whether an event was unexpected.

The court may need to examine:

• contractual wording;
• statutory requirements;
• whether performance became impossible;
• whether performance was merely more expensive;
• causation;
• mitigation;
• allocation of contractual risk.

22. Hardship and Changed Circumstances

Hardship is different from absolute impossibility.

A party may argue:

“Performance is technically possible, but circumstances have fundamentally changed and performance has become exceptionally burdensome.”

The court must distinguish:

impossible performance
from
difficult or expensive performance.

This distinction is extremely important in long-term UAE commercial contracts.

23. Liquidated Damages

Parties may agree in advance upon an amount payable following breach.

Such clauses are commercially useful because they:

• provide certainty;
• reduce disputes about quantification;
• allocate risk;
• encourage performance.

But courts may have statutory authority to examine whether the agreed amount corresponds appropriately to the actual loss or applicable legal standards.

Therefore:

Contractual damages are not automatically immune from judicial scrutiny.

24. Restitution

Restitution aims to reverse an unjust transfer or restore parties following circumstances such as:

• invalidity;
• cancellation;
• termination where legally applicable;
• mistaken payment;
• unjust enrichment.

Example

A buyer pays AED 1 million under a transaction that is subsequently legally cancelled. The question may arise whether the buyer should receive the payment back and whether additional consequences follow.

25. Ownership and Property Rights

Property law covers:

• ownership;
• possession;
• use;
• transfer;
• co-ownership;
• security rights;
• usufruct;
• mortgages;
• other real rights.

A key distinction is between:

Personal right

A claim against a particular person.

Real right

A right directly connected to property and enforceable according to the applicable property regime.

26. Mortgage and Real Security

A mortgage gives a creditor security over property.

Important concepts include:

• creation of security;
• registration;
• priority;
• enforcement;
• sale;
• distribution of proceeds;
• competing creditors.

UAE property disputes frequently require coordination between civil-law principles and specialised real-estate legislation.

27. Personal Guarantees

A guarantee involves a person undertaking responsibility for another person's obligation.

Key questions include:

• What obligation is guaranteed?
• What is the extent of the guarantee?
• Is the guarantee conditional?
• When can the creditor proceed against the guarantor?
• Can the guarantor raise the principal debtor's defences?

Guarantees are particularly significant in:

• banking;
• construction;
• corporate finance;
• property transactions;
• commercial lending.

28. Agency and Authority

Agency concerns situations where one person acts on behalf of another.

Questions include:

• Was authority granted?
• Was the agent acting within authority?
• Did the principal ratify the transaction?
• Did the third party reasonably rely upon apparent authority?
• Who bears responsibility for unauthorised acts?

This concept is crucial for companies because directors, managers and authorised representatives frequently enter contracts on behalf of legal entities.

29. Prescription and Limitation

Limitation rules determine how long a claimant may have to bring an action.

The purpose is to promote:

• legal certainty;
• finality;
• preservation of evidence;
• prevention of extremely old claims.

The applicable period depends upon the type of claim and the relevant legislation.

Therefore, a civil-law lawyer should always ask:

What is the cause of action, and what limitation regime governs it?

30. Evidence and Burden of Proof

A civil claim requires evidence.

Important evidence concepts include:

• burden of proof;
• documentary evidence;
• expert evidence;
• witness evidence;
• electronic evidence;
• admissions;
• presumptions;
• authenticity;
• reliability.

Modern UAE civil litigation increasingly involves:

• emails;
• WhatsApp messages;
• electronic signatures;
• blockchain records;
• digital contracts;
• cloud records;
• AI-generated material.

31. Jurisdiction

Before examining the merits, courts must determine:

Which court has authority to hear the dispute?

The UAE presents a particularly important jurisdictional environment because disputes may involve:

• mainland UAE courts;
• DIFC Courts;
• ADGM Courts;
• arbitral tribunals;
• foreign courts.

The distinction between jurisdiction and governing law is fundamental.

A court may have jurisdiction while applying a different substantive law.

32. Governing Law

Governing law answers:

Which legal rules determine the parties' substantive rights and obligations?

For example:

• UAE mainland law;
• DIFC law;
• ADGM law;
• English law;
• another foreign law.

In DIFC Investments LLC v Mohammed Akbar Mohammed Zia, the DIFC Court specifically examined the contractual governing-law framework and concluded that DIFC law governed the contracts in question.

This illustrates a crucial UAE concept:

Jurisdiction and governing law are separate questions.

33. Arbitration

Arbitration is one of the most important methods of commercial dispute resolution in the UAE.

Key concepts include:

• arbitration agreement;
• tribunal jurisdiction;
• seat;
• governing law;
• procedural law;
• interim measures;
• evidence;
• arbitral award;
• setting aside;
• enforcement.

The UAE Federal Arbitration Law provides the statutory framework for mainland arbitration.

34. Joinder and Multi-Party Disputes

Modern commercial disputes frequently involve:

• owner;
• contractor;
• subcontractor;
• consultant;
• insurer;
• broker;
• bank;
• shareholder;
• guarantor.

The legal system therefore has to balance:

efficiency + consent + procedural fairness + jurisdiction.

This is especially important in arbitration because a party ordinarily cannot simply be forced into arbitration merely because it is commercially connected to the dispute.

35. Enforcement of Judgments and Awards

Winning a judgment or arbitration is only part of litigation.

The successful party may still need to:

• identify assets;
• obtain enforcement orders;
• attach property;
• enforce against bank accounts;
• execute against commercial assets;
• address foreign judgments or awards.

Therefore:

Adjudication determines the right; enforcement makes the right practically effective.

36. Digital Assets and Virtual Property

Modern civil law increasingly has to answer questions involving:

• cryptocurrency;
• tokens;
• NFTs;
• digital accounts;
• virtual property;
• smart contracts;
• digital securities.

Important civil-law questions include:

• Who owns the digital asset?
• Can it be transferred?
• Can it be pledged?
• Is it property or merely a contractual entitlement?
• What happens when a platform freezes an account?
• Who bears the loss from hacking?
• How is ownership proved?

These questions require interaction between civil law, financial regulation, cybersecurity, evidence and technology law.

37. AI and Civil Liability

Artificial intelligence introduces new civil-law questions.

Potential disputes include:

• AI-generated defamation;
• discriminatory automated decisions;
• defective AI products;
• autonomous systems;
• AI contractual decisions;
• algorithmic errors;
• data misuse;
• professional negligence involving AI.

The fundamental civil-law questions remain familiar:

Duty → breach → causation → damage → remedy.

What changes is the difficulty of identifying the legally responsible human or organisation.

38. Case Law: Six Important Authorities

Case 1 — DAMAC Park Towers v Youssef Issa Ward [2015] DIFC CA 006

This case concerned contractual interpretation in a real-estate context.

The DIFC Court of Appeal dealt with the proper approach to interpreting contractual language. It is frequently useful for understanding the principle that courts interpret the contract according to the legally applicable interpretive framework rather than rewriting the parties' bargain.

Concept illustrated:

Contractual interpretation and party autonomy.

Exam point:

Courts interpret contracts; they do not ordinarily create a new bargain for the parties.

Status: DIFC authority; comparative rather than binding mainland UAE precedent.

Case 2 — DIFC Investments LLC v Mohammed Akbar Mohammed Zia [2017] CFI 001 / [2018] CA 005

The dispute involved 72 property contracts and non-payment by the purchaser.

The DIFC Court of First Instance held that the contracts had been terminated under the applicable DIFC Contract Law. The Court of Appeal dismissed the appeal.

Concept illustrated:

Breach, termination and governing law.

Importance:

It demonstrates how courts distinguish:

• existence of a contract;
• applicable law;
• contractual obligations;
• breach;
• termination.

Case 3 — Ashok Kumar Goel v Credit Suisse [2021] DIFC CA 002

The dispute involved guarantees given in connection with credit facilities.

The DIFC Court of Appeal addressed jurisdictional and contractual questions surrounding the guarantees and ultimately dismissed the appeal.

Concept illustrated:

Guarantees, jurisdiction and contractual obligations.

Exam lesson:

Always identify the contractual instrument and applicable jurisdiction before determining substantive liability.

Case 4 — The Industrial Group Ltd v Abdelazim El Shikh El Fadil Hamid [2022] DIFC CA 005 & 006

The case concerned employment-related monetary claims and interpretation of the applicable DIFC employment legislation.

The Court of Appeal dismissed the appeals.

Concept illustrated:

Statutory interpretation and legislative primacy.

Broader civil-law lesson:

Courts must apply the governing statute rather than simply import a preferred rule from another legal system.

Case 5 — Lals Holdings Ltd v Emirates Insurance Co & Siaci Insurance Brokers [2024] DIFC CA 002

The case concerned business-interruption insurance arising from the COVID-19 pandemic and contractual interpretation of insurance coverage.

The Court of Appeal dismissed the appeal. The judgment discussed the statutory framework applicable to interpretation and explained the relationship between statutory DIFC rules and common-law approaches.

Concepts illustrated:

• contract interpretation;
• insurance contracts;
• statutory interpretation;
• commercial context;
• broker obligations.

Important qualification

This is a DIFC case and should not be cited as if it were a mainland UAE Federal Supreme Court judgment.

Case 6 — Shihab Khalil v Shuaa Capital PSC [2009] DIFC CFI 017

The case involved allegations concerning duties of care, fiduciary obligations and contractual rights.

The DIFC Court considered claims based on the DIFC Law of Obligations and fiduciary duties.

Concepts illustrated:

• civil duties;
• fiduciary obligations;
• tortious/civil liability;
• contractual obligations.

It is particularly useful when studying the difference between contractual liability and independent civil duties.

Case 7 — Carmon Reestrutura-Engenharia v Cuenda [2024] DIFC CA 003

The DIFC Court of Appeal considered issues arising from a worldwide freezing order and related jurisdictional/enforcement questions.

Concepts illustrated:

• interim relief;
• asset preservation;
• jurisdiction;
• enforcement-related civil remedies.

39. Case-Law Revision Table

Important: These authorities are primarily DIFC decisions. They are useful for UAE legal study and comparative analysis, but they should not be presented as binding mainland UAE precedent. The new 2026 Civil Transactions Law must be checked for the current mainland rule.

40. The Five Most Important Civil-Law Relationships

For examination and practical problem-solving, remember these five relationships:

1. Contract → Performance → Breach → Remedy

A valid contract creates obligations.
Failure to perform may constitute breach.
Breach can produce legally available remedies.

2. Wrongful Conduct → Damage → Causation → Compensation

Civil liability generally requires a legally recognised basis of liability and damage connected to the defendant's conduct.

3. Right → Exercise → Abuse

Possessing a legal right does not necessarily mean every method of exercising it is legally acceptable.

4. Jurisdiction → Governing Law → Remedy

First ask:

Which court/tribunal?

Then:

Which substantive law?

Then:

Which remedy?

5. Judgment/Award → Enforcement

A successful claimant must ultimately convert the legal decision into practical recovery.

41. Current UAE Civil-Law Study Framework

For 2026 onward, a useful study hierarchy is:

A. General Civil Law

Civil Transactions Law — Federal Decree-Law No. 25 of 2025

B. Procedure

Relevant UAE civil-procedure legislation.

C. Evidence

Current UAE evidence legislation.

D. Arbitration

Federal Law No. 6 of 2018 on Arbitration, where mainland arbitration applies.

E. Commercial Law

Commercial Companies Law and other commercial legislation.

F. Specialised Regulation

Depending upon the dispute:

• real estate;
• banking;
• insurance;
• consumer law;
• employment;
• data protection;
• financial services;
• intellectual property;
• cybersecurity;
• digital assets.

The new Civil Transactions Law expressly repealed the former 1985 Civil Transactions Law from its effective date of 1 June 2026.

42. Must-Know Concepts for Quick Revision

If you need to remember only the essentials, learn these 20 concepts first:

1. Legal personality
2. Capacity
3. Obligation
4. Contract
5. Consent
6. Mistake
7. Fraud/misrepresentation
8. Good faith
9. Freedom of contract
10. Contract interpretation
11. Performance
12. Breach
13. Termination
14. Damages
15. Causation
16. Unjust enrichment
17. Abuse of rights
18. Tort/civil liability
19. Property/security rights
20. Arbitration and enforcement

43. Final Conclusion

The core of UAE civil law can be understood through one integrated chain:

Person → Right → Obligation → Contract or Civil Duty → Performance → Breach/Wrong → Damage → Causation → Remedy → Enforcement.

The most important modern development is that UAE civil-law study must now be aligned with the 2026 Civil Transactions Law, while older jurisprudence should be used carefully and only where its underlying principle remains applicable.

For advanced study, the next layer is the interaction between traditional concepts—good faith, abuse of rights, compensation, unjust enrichment, property and contractual liability—and newer issues such as digital assets, electronic evidence, AI liability, platform responsibility, smart contracts and automated decision-making.
