Civil Law And UAE Basic Fault and Responsibility Rules

1. Introduction

In UAE civil law, fault and responsibility are central concepts for determining when a person must compensate another person for loss or injury.

The basic question is:

When does a person's conduct create legal responsibility for harm suffered by another person?

Civil responsibility may arise from:

breach of contract;

tortious or unlawful conduct;

professional negligence;

defective products;

construction defects;

property damage;

traffic or other accidents;

breach of statutory duties;

misuse of rights;

negligent digital or cybersecurity conduct.

A basic civil-liability analysis normally requires examination of:

Duty/obligation → Fault → Damage → Causation → Remedy

2. Current UAE Legal Framework

The current framework must be understood in light of the Federal Decree-Law No. 25 of 2025 promulgating the Civil Transactions Law, which became effective on 1 June 2026 and replaced the former 1985 Civil Transactions Law.

The new Civil Transactions Law continues the fundamental civil-law approach to:

obligations;

contractual responsibility;

unlawful conduct;

compensation;

causation;

good faith;

abuse of rights.

Other important legislation may apply depending upon the dispute, including:

Federal Decree-Law No. 42 of 2022 on Civil Procedure;

Federal Decree-Law No. 35 of 2022 on Evidence in Civil and Commercial Transactions;

Federal Law No. 6 of 2018 on Arbitration;

consumer-protection legislation;

special construction, banking, insurance, transportation and other sectoral laws.

Important historical point

Many UAE cases discussed below were decided under the former Federal Law No. 5 of 1985. They remain useful for understanding established UAE principles, but they should be treated as historical or persuasive authorities when applying the new Civil Transactions Law from 1 June 2026.

3. Meaning of Fault

Fault means legally blameworthy conduct that causes or contributes to legally recognised harm.

Fault may involve:

intentional conduct;

negligence;

lack of reasonable care;

failure to perform an obligation;

improper performance;

failure to take necessary precautions.

Simple example

A contractor knows that a structural component is defective but installs it anyway.

If the defect subsequently causes property damage, the contractor's conduct may constitute fault and generate civil responsibility.

4. Meaning of Civil Responsibility

Civil responsibility means the legal obligation to answer for harm caused to another person and, where the legal requirements are satisfied, provide an appropriate remedy.

The principal remedy is generally compensation, although other remedies may be available, including:

restitution;

repair;

replacement;

specific performance;

termination;

injunction-type relief where legally available;

agreed contractual remedies.

5. Basic Elements of Civil Responsibility

A useful examination formula is:

1. Fault or breach

2. Damage

3. Causation

4. Legal responsibility

5. Appropriate remedy

These elements must be analysed together.

Example

A driver negligently damages another person's vehicle.

Negligent driving = possible fault.

Vehicle damage = damage.

Collision caused the damage = causation.

Driver is legally responsible = responsibility.

Repair cost = possible compensation.

6. Contractual Responsibility

Contractual responsibility arises where a party fails to perform an obligation properly.

Examples include:

failure to deliver goods;

late performance;

defective construction;

failure to pay;

improper professional services;

breach of confidentiality;

wrongful termination.

The claimant generally needs to establish:

existence of the contractual obligation;

breach or defective performance;

legally recognised loss;

causal connection between breach and loss.

7. Tortious or Non-Contractual Responsibility

Civil responsibility can also arise independently of a contract.

For example:

A person negligently damages a neighbour's property.

There may be no contract between the parties, but the conduct can still create civil responsibility.

Typical tortious situations include:

personal injury;

property damage;

professional negligence;

environmental harm;

negligent maintenance;

unlawful interference;

cybersecurity-related loss.

8. Intentional Fault

The most obvious form of fault occurs where the person intentionally causes harm.

Example

A person deliberately destroys another person's equipment.

The intentional conduct can establish responsibility if the other legal requirements are satisfied.

Intentional conduct may also have criminal consequences, but criminal responsibility and civil responsibility are legally distinct.

A criminal proceeding does not eliminate the possibility of a civil claim for compensation.

9. Negligence

Negligence generally involves failure to exercise the level of care required by the circumstances.

Examples:

leaving dangerous equipment unsecured;

failing to maintain a building;

professional errors;

inadequate safety precautions;

negligent cybersecurity practices;

careless handling of another person's property.

Important question

The court must consider the circumstances rather than applying an abstract idea of carelessness.

10. Professional Fault

Professionals may incur civil responsibility where their conduct falls below the applicable professional or contractual standard.

Examples include:

engineers;

architects;

consultants;

accountants;

lawyers;

doctors;

financial professionals;

technology providers.

Professional responsibility often requires expert evidence because the court may need assistance in determining the applicable technical standard.

11. Construction Responsibility

Construction disputes commonly involve:

defective design;

defective materials;

defective workmanship;

negligent supervision;

delay;

structural defects.

Responsibility may potentially be distributed among:

Owner → Developer → Consultant → Architect → Contractor → Subcontractor

The court must identify the actual source of the defect and establish causation.

12. Fault Does Not Automatically Equal Responsibility

An important principle is:

Fault alone is generally insufficient.

Suppose a contractor made a minor technical error but the claimant's loss resulted entirely from an independent event.

The claimant may fail to establish the necessary causal connection.

Therefore:

Fault + Damage + Causation

is more important than fault considered in isolation.

13. Damage

There must generally be legally recognised damage before compensation can be awarded.

Damage may include:

A. Material damage

property loss;

repair expenses;

medical expenses;

financial loss;

loss of income.

B. Moral/non-material damage

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

pain;

emotional suffering;

injury to reputation;

infringement of personal interests.

C. Future damage

Future losses may be relevant where they are sufficiently established rather than purely speculative.

14. Causation

Causation connects the fault to the damage.

The central question is:

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

Example

A contractor negligently leaves a pipe unsecured.

The pipe breaks and floods a building.

If the evidence establishes that the negligent installation caused the flooding, causation may be established.

But if an extraordinary independent event caused the flooding, the causal analysis may be different.

15. Direct and Indirect Causes

Civil disputes may involve multiple causes.

For example:

Contractor makes an error.

Building manager fails to inspect it.

Extreme weather occurs.

Property is damaged.

The court may need to determine:

which factors materially caused the damage;

whether there was an intervening event;

whether several persons contributed;

whether the claimant contributed to the loss.

16. Multiple Tortfeasors

Sometimes several persons contribute to the same harm.

For example:

negligent contractor;

negligent consultant;

negligent subcontractor.

The court may have to determine:

whether each person's conduct contributed to the damage;

the relationship between their conduct;

allocation of responsibility;

appropriate compensation.

This is particularly important in construction, transportation and professional-liability disputes.

17. Contributory Conduct of the Claimant

The claimant's own conduct can be relevant.

Example

A property owner knows that a dangerous area exists but deliberately enters it despite adequate warnings.

The court may consider the claimant's conduct when assessing responsibility and compensation, depending on the applicable statutory rules and circumstances.

Thus:

The defendant's fault is not always the only relevant conduct.

18. Force Majeure and External Events

An extraordinary external event may affect responsibility where it legally qualifies as a force-majeure or causation-breaking event.

Examples may include:

extraordinary natural events;

certain government measures;

unforeseeable external events;

events that cannot reasonably be prevented.

However, commercial difficulty is not automatically force majeure.

A party cannot simply label an ordinary business problem as force majeure.

19. Abuse of Rights

The UAE civil-law system also recognises the principle against abuse of rights.

A person may technically possess a legal right but exercise it in an abusive manner.

Factors may include:

absence of legitimate interest;

disproportionate harm;

intention to cause harm;

conduct contrary to established legal principles.

This doctrine is especially relevant to:

contractual termination;

property rights;

enforcement;

creditor-debtor relationships.

20. Good Faith

Good faith is important in contractual relationships.

Parties should perform contractual obligations consistently with:

honesty;

cooperation;

legitimate expectations;

the nature of the contractual relationship.

Good faith does not mean that a party must surrender its contractual rights. Rather, it influences how those rights and obligations are interpreted and performed.

21. Fault in Contract and Fault in Tort

22. Evidence of Fault

Under the UAE Evidence Law, courts may consider different types of evidence.

Important evidence includes:

contracts;

invoices;

emails;

WhatsApp messages;

photographs;

CCTV;

expert reports;

bank records;

inspection reports;

technical records;

admissions;

electronic records.

Electronic evidence

Modern fault disputes can involve:

server logs;

access records;

cybersecurity reports;

automated-system records;

GPS data;

digital communications.

The court must assess authenticity and probative value.

23. Role of Expert Evidence

Experts are particularly important where fault involves technical questions.

For example, in a construction case an expert may determine:

whether the work was defective;

the relevant technical standard;

the cause of the defect;

whether maintenance contributed;

the cost of repair.

The expert provides technical assistance; the court remains responsible for the legal determination.

24. Fault and AI Systems

Modern UAE civil disputes may involve AI-assisted systems.

For example:

an AI system incorrectly approves a transaction;

an automated system causes a financial loss;

an algorithm misclassifies a customer;

an autonomous system produces defective output.

The key legal questions remain:

Who controlled the system?

Who designed it?

Who deployed it?

Was there negligent supervision?

Was there inadequate testing?

Was there a foreseeable risk?

Did the system actually cause the damage?

Was human intervention possible?

AI itself should not automatically be treated as a legal person responsible for the loss.

25. Cybersecurity Fault

A business may potentially face civil responsibility where inadequate cybersecurity causes legally recognised harm.

Possible examples:

failure to protect customer data;

inadequate access controls;

failure to patch critical vulnerabilities;

negligent handling of confidential information.

However, liability still requires analysis of:

Duty → Fault → Damage → Causation

A cyberattack occurring does not automatically prove that the victim organisation was legally negligent.

26. Ten Relevant UAE Case Laws

Because UAE courts do not operate under a strict common-law doctrine of binding precedent, the following cases should be understood according to their legal reasoning and persuasive value. Several are general evidentiary, contractual or causation authorities rather than direct modern negligence cases.

Case 1: Dubai Court of Cassation – Case No. 266/2008

Principle

The case is relevant to causation and concurrent causes.

The court's reasoning illustrates the importance of determining the causal connection between conduct and resulting harm where more than one factor may have contributed.

Relevance

This is highly useful in fault cases involving:

multiple actors;

construction defects;

accidents;

intervening events.

Case 2: UAE Federal Supreme Court – Civil Appeal No. 79/2020

Principle

The case concerned the evidentiary significance of an admission.

An admission may significantly affect the issues that remain to be proved.

Relevance to fault

A party's admission concerning:

breach;

conduct;

payment;

responsibility;

contractual performance

can materially affect a civil-liability dispute.

Case 3: UAE Federal Supreme Court – Commercial Appeal No. 215/2020

Principle

The case concerned expert evidence and the court's treatment of an expert report.

Relevance

Fault frequently depends upon technical evidence.

For example:

Was the engineer negligent?

Was the construction work defective?

Did the bank's accounting calculation contain an error?

Expert evidence can therefore become central to establishing responsibility.

Case 4: UAE Federal Supreme Court – Penal Cassation No. 1093/2019

Principle

The case illustrates the court's authority to assess and weigh evidence and determine its probative value.

Relevance

Although arising in the criminal context, the broader evidentiary reasoning is useful when considering proof of:

conduct;

knowledge;

causation;

documentary evidence.

It should therefore be treated as analogical rather than a direct civil-negligence precedent.

Case 5: UAE Federal Supreme Court – Penal Cassation No. 1422/2022

Principle

The court emphasised the importance of sufficiently probative evidence supporting judicial conclusions.

Relevance

A claimant alleging negligence cannot simply make an accusation of fault.

There must be evidence supporting:

the relevant conduct;

the alleged breach;

the resulting damage;

causal connection.

Case 6: UAE Federal Supreme Court – Penal Cassation No. 660/2023

Principle

The court may reach its conclusion by considering the totality of evidence, provided the inference is logically supported.

Relevance

This is particularly important where no single piece of evidence independently establishes fault.

For example:

emails;

expert report;

photographs;

payment records;

witness evidence

may collectively establish responsibility.

Case 7: Dubai Court of Cassation – Civil Appeal No. 6/2017

Principle

The case is relevant to the interpretation and enforcement of contractual obligations.

Relevance

Where responsibility arises from breach of contract, the court must first identify:

what the contract required;

what the party actually did;

whether that constituted breach;

what consequences legally follow.

Case 8: Dubai Court of Cassation – Appeal No. 440/2016

Principle

The case is relevant to contractual performance, termination and good-faith considerations.

Relevance

A party exercising contractual rights must be assessed within the applicable contractual and legal framework rather than treating termination as automatically lawful merely because one party claims a contractual power.

Case 9: Dubai Court of Cassation – Case No. 735/2024

Principle

The case concerned interpretation of arbitration provisions and the parties' contractual intention.

Relevance to responsibility

Before determining liability, a court must establish whether it has jurisdiction to hear the dispute.

This demonstrates that procedural responsibility and substantive responsibility are separate questions.

Case 10: Abu Dhabi Court of Cassation – Case No. 902/2024

Principle

The case concerned authority to bind a legal entity in relation to arbitration.

Relevance

Corporate authority can become critical where a company attempts to enforce contractual rights or dispute-resolution provisions.

It also demonstrates the importance of identifying who legally acted for the company.

27. Construction Example of Fault

Suppose a contractor constructs a commercial building.

Six months later:

cracks appear;

water enters the building;

equipment is damaged.

The owner claims AED 5 million.

The court may ask:

Question 1

Was there actually a defect?

Question 2

What caused the defect?

Question 3

Was the contractor responsible?

Question 4

Did the consultant contribute?

Question 5

Did the owner fail to maintain the property?

Question 6

What damage was actually caused?

Question 7

Is the claimed amount proved?

Thus, fault analysis is much more sophisticated than simply asking:

“Who made a mistake?”

28. Banking Example

Suppose a bank processes an unauthorised electronic transaction.

The customer claims:

“The bank was negligent.”

The court may examine:

authentication records;

customer instructions;

device information;

transaction logs;

security procedures;

warnings;

customer conduct;

expert evidence;

applicable banking regulations.

The existence of an unauthorised transaction does not automatically answer every question about responsibility.

29. Product Liability Example

Suppose a consumer purchases an electrical appliance that catches fire.

Potentially relevant persons may include:

manufacturer;

importer;

distributor;

retailer.

The investigation may consider:

product defect;

manufacturing process;

warnings;

instructions;

consumer misuse;

maintenance;

causal connection.

The legal basis may arise from special consumer/product legislation as well as general civil-liability principles.

30. Distinction Between Fault and Strict Responsibility

Not every form of civil responsibility necessarily depends upon proving ordinary negligence in exactly the same way.

Certain statutory or special regimes may impose responsibility based upon specific conditions, status, control, contractual undertaking, or special legal rules.

Therefore:

Never assume that every UAE civil claim requires identical proof of subjective negligence.

The applicable legislation must first be identified.

31. Fault and Compensation

Once responsibility is established, the court considers the appropriate remedy.

Compensation should be connected to the legally recognised loss caused by the responsible conduct.

A claimant should therefore establish:

Wrongful conduct → Damage → Causation → Quantifiable loss

Example

If a contractor's defect causes AED 500,000 of proven repair costs, the claimant cannot automatically demand AED 10 million merely because the defect was serious.

The amount must be legally and evidentially supported.

32. Fault, Limitation and Procedure

Even a substantively strong claim can face procedural problems.

A claimant should examine:

applicable limitation period;

competent court;

arbitration agreement;

mandatory notice;

contractual claim procedure;

evidence requirements;

appeal deadlines.

Therefore:

Substantive fault and procedural enforceability are separate issues.

33. Basic Fault Analysis Formula

For examination or practical legal analysis, use:

D → F → D → C → R

Where:

D = Duty/obligation

F = Fault or breach

D = Damage

C = Causation

R = Responsibility/remedy

A fuller version is:

Duty + Breach/Fault + Damage + Causation + No applicable defence = Civil Responsibility

34. Common Defences

A defendant may argue:

no duty existed;

no breach occurred;

no fault;

no actual damage;

damage was caused by another person;

lack of causation;

intervening event;

force majeure;

claimant's own conduct;

contributory fault;

contractual limitation;

limitation period;

lack of jurisdiction;

arbitration agreement;

lack of authority;

insufficient evidence.

35. Quick Revision Table

36. Conclusion

The UAE's basic approach to fault and civil responsibility can be summarised as follows:

Identify the applicable legal duty or contractual obligation.

Determine whether there was a breach or fault.

Establish actual legally recognised damage.

Prove causation.

Consider intervening events and the claimant's conduct.

Examine possible defences.

Determine the legally appropriate remedy.

Ensure the claim satisfies procedural and limitation requirements.

The most important principle is:

Fault does not automatically create liability; the claimant normally must connect the legally relevant conduct to legally recognised damage through adequate evidence and causation.

For modern UAE disputes involving construction, banking, professional negligence, cybersecurity and AI, the same foundational structure remains highly useful, although special legislation may modify the precise requirements of responsibility.

Note on the case laws: The cases listed above include direct, general and analogical authorities. UAE courts do not follow strict stare decisis, and many cited decisions predate the Civil Transactions Law effective 1 June 2026. They should therefore be used as persuasive/foundational authorities alongside the current statutory text, rather than assumed to be direct interpretations of the new 2026 Code.
