Civil Law and UAE Basic Fault Concept in Law

1. Meaning of Fault in UAE Civil Law

In UAE civil law, fault is a central concept in determining civil responsibility. In simple terms, fault means conduct that violates a legal duty or the standard of care required in the circumstances and thereby causes legally recognized harm.

Fault may arise through:

An intentional act;

Negligence;

Carelessness;

Failure to take reasonable precautions;

Violation of a legal obligation;

Improper professional conduct;

Breach of contractual obligations; or

Conduct that causes legally compensable harm.

The basic civil-law sequence can be expressed as:

Fault → Causation → Damage → Civil Liability → Compensation

However, the exact requirements depend upon whether the claim is based on contractual liability, tort/delict, statute, or another special legal regime.

2. Fault Under the Current UAE Legal Framework

The current UAE Civil Transactions Law is Federal Decree-Law No. 25 of 2025, effective from 1 June 2026, replacing the former Federal Law No. 5 of 1985.

The current system should therefore be distinguished from older UAE Court of Cassation decisions that interpreted the 1985 legislation.

The current law continues the fundamental civil-law idea that legally attributable harmful conduct can create an obligation to compensate the injured person.

The current compensation framework particularly requires attention to:

the harmful conduct;

causal connection;

actual loss;

lost profit where legally recoverable;

moral harm;

contribution by the injured person; and

responsibility of multiple persons.

3. Fault and Civil Liability

Fault should not be confused with damage.

For example:

A driver negligently hits another vehicle.

There are several separate legal questions:

Question 1 — Was there fault?

Was the driver careless or otherwise legally responsible?

Question 2 — Did the fault cause the accident?

There must be a causal connection.

Question 3 — Did the accident cause legally recognized damage?

There must be actual compensable harm.

Question 4 — What compensation is appropriate?

The court assesses the legally established loss.

Thus:

Fault alone ≠ automatic compensation for every claimed amount.

4. Main Forms of Fault

A. Intentional Fault

Intentional fault occurs where a person deliberately performs the harmful act.

Examples:

Deliberately damaging another person's property;

Deliberately publishing harmful false statements;

Intentionally interfering with another person's contractual rights;

Deliberately destroying commercial information.

Intent can strengthen the basis for civil responsibility, although the claimant must still establish the legally relevant damage and causation.

5. Negligence

Negligence is one of the most common forms of civil fault.

It generally involves failure to exercise the level of care reasonably expected in the circumstances.

Examples:

A driver ignores traffic conditions;

A contractor fails to follow safety requirements;

A professional fails to apply appropriate standards;

A property owner ignores a dangerous condition;

A business fails to take reasonable precautions against foreseeable harm.

The court examines the surrounding circumstances rather than merely asking whether the claimant suffered damage.

6. Recklessness and Serious Carelessness

Conduct may be more serious than ordinary negligence.

Examples include:

knowingly ignoring an obvious risk;

repeatedly violating safety requirements;

consciously taking an unjustified risk;

ignoring professional warnings.

Such circumstances can be important when determining civil responsibility and the seriousness of the conduct.

7. Fault in Contractual Relationships

Fault can also arise through failure to perform contractual obligations.

For example:

Contract → Duty to perform → Failure/improper performance → Damage

A contractor who fails to perform agreed work may be responsible for the consequences of the breach where the legal requirements for contractual liability are satisfied.

Similarly:

a seller may fail to deliver goods;

a bank may improperly handle a contractual transaction;

a consultant may provide defective contractual services;

a tenant may violate contractual obligations;

a construction company may perform defective work.

The court must first identify the contractual obligation and then determine whether the conduct legally amounts to breach.

8. Fault in Tort / Civil Wrong

Tortious or delictual fault generally concerns unlawful harmful conduct outside, or independently of, contractual performance.

Typical examples include:

Negligent injury;

Property damage;

Defamation-related harm;

Professional negligence;

Unsafe premises;

Damage caused to third parties;

Certain environmental or commercial harms.

The central structure is:

Wrongful conduct + legally effective causation + damage = civil responsibility

9. Objective and Subjective Aspects of Fault

Fault can involve both:

Subjective considerations

What did the person know?

What did they intend?

Did they appreciate the risk?

Objective considerations

What would reasonably be expected from a person in the same circumstances?

What professional or safety standards applied?

What precautions were reasonably required?

The precise test depends on the type of legal relationship and the applicable statutory rules.

10. Professional Fault

Professionals may be judged according to the standards applicable to their professional activity.

Examples include:

Engineers;

Architects;

Doctors;

Accountants;

Lawyers;

Financial professionals;

Technical consultants.

Professional fault may require technical evidence.

For example, in a construction dispute, the court may require an expert to determine whether the engineer's work departed from accepted technical standards.

But the expert does not finally decide legal liability. The court determines the legal consequences.

11. Expert Evidence and Fault

UAE Court of Cassation jurisprudence repeatedly emphasizes the distinction between:

Technical question → Expert

and

Legal question → Court

For example, an expert may determine:

whether construction work was technically defective;

the percentage of physical damage;

the amount of repair cost;

accounting discrepancies;

medical consequences.

But the court decides:

whether the conduct constitutes legal fault;

whether a legal duty was breached;

whether causation exists;

whether compensation is legally recoverable.

12. Causation Is Essential

Fault without causation does not automatically create liability for every consequence.

Suppose:

A contractor commits a minor contractual error, but a completely independent event later destroys the building.

The claimant must establish that the contractor's fault legally caused the claimed loss.

The court may examine:

factual causation;

intervening events;

third-party conduct;

force majeure;

claimant's own conduct;

foreseeability/natural consequence;

technical evidence.

13. Contributory Fault

An injured person may sometimes contribute to their own injury.

For example:

A claimant ignores clear safety instructions and thereby increases the severity of the injury.

The court may consider this contribution when assessing compensation.

Under the current Civil Transactions Law, the court may reduce or, in appropriate circumstances, deny compensation where the injured person's conduct contributed to or aggravated the damage.

14. Multiple Persons and Fault

A single harmful event may involve several responsible parties.

Example:

A construction accident results from:

defective design;

contractor negligence;

subcontractor negligence; and

inadequate safety supervision.

The court must determine the legally relevant responsibility of each party.

The current law provides mechanisms for dealing with multiple persons responsible for damage, including proportionate responsibility and, where legally appropriate, joint/several responsibility.

15. Fault and Damage

Fault and damage are separate concepts.

Fault

The legally wrongful or negligent conduct.

Damage

The legally recognized harm resulting from that conduct.

For example:

A driver negligently causes an accident.

Fault: negligent driving.

Damage: vehicle destruction, medical expenses, bodily injury, lost income, etc.

Causation: accident caused the injuries and property loss.

Remedy: appropriate compensation.

16. Important UAE Case Laws

Case 1 — UAE Court of Cassation, Civil Cassation No. 99 of Judicial Year 16, 17 December 1995

This is an important historical UAE authority on harmful acts and civil responsibility.

The Court discussed the distinction between direct harm and indirect causation and examined when conduct can legally generate an obligation to compensate.

The judgment also considered circumstances capable of breaking causal responsibility, including external causes and conduct of the injured person or third parties.

Importance

The case is useful for understanding:

fault;

causation;

direct harm;

indirect causation;

external causes;

contributory conduct.

Historical qualification: The case was decided under the former 1985 Civil Transactions Law and should therefore be treated as historical/analogical authority under the current 2026 framework.

17. Case 2 — UAE Court of Cassation, Civil Cassation Nos. 434 and 448 of 2007

These decisions concerned compensation for bodily and moral damage and the assessment of responsibility.

The Court recognized the importance of medical evidence in determining the consequences of injury and confirmed the trial court's role in assessing compensation where the law does not prescribe a precise mathematical formula.

Relevance to fault

The cases demonstrate that establishing fault is only one stage.

The claimant must also establish:

Fault → Injury → Causation → Compensable consequences

Importance

Useful for:

personal injury;

medical evidence;

civil responsibility;

moral damage;

compensation assessment.

These are historical authorities under the former legislation.

18. Case 3 — UAE Court of Cassation, Civil Cassation No. 647 of 2021, 20 September 2021

The Court emphasized the requirement that judgments demonstrate a proper examination of the facts and evidence and address material defenses capable of affecting the outcome.

Relevance to fault

In a civil fault dispute, important evidence might include:

accident reports;

expert reports;

contracts;

photographs;

correspondence;

technical records;

witness evidence.

The court must adequately consider material evidence rather than simply asserting that fault has been established.

Principle

A legally sufficient finding of fault should be supported by adequate reasoning.

19. Case 4 — UAE Court of Cassation, Commercial Cassation No. 215 of 2020, 5 May 2020

This case is particularly relevant where fault depends on expert evidence.

The Court held, in substance, that a court relying on an expert report must have an adequate reasoned basis for doing so and cannot merely adopt conclusions without addressing significant objections capable of affecting the result.

Example

In a construction negligence case:

Expert: identifies defective workmanship.

Court: decides whether that defect constitutes legally relevant fault and whether it caused the claimed damage.

Importance

The case is useful for:

professional negligence;

construction fault;

accounting fault;

banking disputes;

technical causation.

20. Case 5 — UAE Court of Cassation, Commercial Cassation No. 767 of 2021, 28 September 2021

The Court emphasized that the expert's function is primarily technical and factual, while legal conclusions remain within the court's jurisdiction.

Importance for fault

An expert can say:

“The engineering work departed from the applicable technical standard.”

But the expert should not finally decide:

“The defendant is legally liable under UAE civil law.”

That determination belongs to the court.

This distinction is particularly important in:

professional negligence;

engineering disputes;

medical negligence;

construction cases;

financial/accounting disputes.

21. Case 6 — UAE Court of Cassation, Commercial Cassation Nos. 1012 and 1023 of 2022, 17 January 2023

The Court dealt with the limits of expert evidence and emphasized that the court must independently examine the contractual and legal basis of responsibility.

Principle

An expert's technical allocation of responsibility does not automatically establish legal liability.

The court must examine:

Contract;

Legal obligation;

Alleged breach;

Technical facts;

Causation;

Damage;

Legal responsibility.

Importance

This is highly useful for determining fault in complex commercial disputes.

22. Case 7 — UAE Court of Cassation, Commercial Cassation No. 240 of 2021, 4 May 2021

The Court emphasized that material objections to an expert report must be properly considered.

Where an objection could affect the result, the court should deal with it appropriately and may need further expert examination.

Fault relevance

Suppose:

claimant's expert says there was negligence;

defendant's expert says there was no technical fault.

The court cannot simply select one conclusion without adequately considering the material technical objections.

Importance

The case protects the evidentiary integrity of fault determinations.

23. Case 8 — UAE Court of Cassation, Commercial Cassation No. 941 of 2019, 24 March 2020

This case concerns the proper legal characterization of a dispute.

The Court emphasized that the court is not necessarily bound by the parties' labels and must give the relationship its correct legal characterization.

Relevance to fault

This matters because the legal test may differ depending upon whether the claim is:

contractual;

tortious;

professional;

statutory; or

otherwise legally grounded.

A claimant cannot establish fault merely by calling conduct “negligence.” The court determines the applicable legal framework.

24. Case 9 — UAE Court of Cassation, Civil Cassation No. 79 of 2020, 17 February 2020

The Court considered the effect of judicial and non-judicial admission.

A sufficiently certain admission intended to establish a right may be binding, and the court must consider the admission as a whole.

Fault relevance

An admission can sometimes establish an important factual element, such as:

responsibility for an act;

receipt of property;

contractual performance;

existence of a transaction;

acknowledgment of a particular event.

The court must still determine the legal consequences.

25. Case 10 — UAE Court of Cassation, Civil Cassation No. 880 of 2021, 15 November 2021

This case is useful because it addresses compensation consequences following legally relevant harmful conduct.

The Court recognized that compensation can encompass qualifying present and future damage and that loss of opportunity may, in suitable circumstances, be compensable.

Relevance to fault

Once fault and causation are established, the claimant's recovery is not necessarily limited to an immediately visible financial loss.

The court may consider legally established consequences of the wrongful conduct.

26. Fault in Different Situations

27. Fault vs. Breach of Contract

These concepts overlap but should not always be treated as identical.

Contractual breach

The question is:

Did the party fail to perform an obligation imposed by the contract?

Tortious fault

The question is:

Did the person's conduct violate a legally protected duty and cause harm?

Where a contract exists, the court must determine the correct legal characterization.

This is why Commercial Cassation No. 941 of 2019 is important.

28. Fault and Professional Standards

Professional fault requires particular care because ordinary lay standards may not be sufficient.

For example, an engineer's conduct may need to be evaluated against:

technical standards;

project specifications;

professional obligations;

contractual requirements;

accepted engineering practice.

Similarly, medical negligence may require medical expert evidence.

The court ultimately decides whether the established facts satisfy the legal test for liability.

29. Fault and Electronic Evidence

Modern UAE litigation can involve:

emails;

WhatsApp messages;

electronic contracts;

digital accounting records;

electronic signatures;

system logs;

photographs;

CCTV;

electronic expert evidence.

The UAE Evidence Law recognizes electronic evidence, subject to its statutory requirements.

Consequently, proving fault increasingly involves establishing:

Who acted → What they did → When they did it → Whether they were authorized → What consequence followed.

30. Practical Fault Analysis

When analysing a UAE civil fault case, use this checklist:

1. Identify the legal duty

What duty did the defendant owe?

2. Identify the conduct

What exactly did the defendant do or fail to do?

3. Establish the standard

What standard of conduct applied?

4. Compare conduct with standard

Was there a departure from the required standard?

5. Establish causation

Did that departure cause the damage?

6. Identify the damage

What actual harm occurred?

7. Establish evidence

What documents or expert evidence prove the claim?

8. Consider contributory conduct

Did the claimant contribute to the harm?

9. Consider third parties

Did another person contribute?

10. Determine compensation

What losses are legally recoverable?

31. Simple Example

Suppose a construction company installs defective electrical equipment.

Stage 1 — Duty

The contractor has a contractual and potentially statutory/professional duty to perform the work properly.

Stage 2 — Fault

The contractor uses defective equipment despite technical requirements.

Stage 3 — Causation

The defective equipment causes an electrical fire.

Stage 4 — Damage

The fire damages:

the building;

machinery;

inventory;

business operations.

Stage 5 — Evidence

Evidence may include:

construction contract;

technical specifications;

photographs;

invoices;

expert report;

fire investigation report;

accounting records.

Stage 6 — Liability

The court determines whether the contractor's conduct legally establishes responsibility.

Stage 7 — Damages

The court determines which losses are causally connected and legally recoverable.

32. Fault and Force Majeure

A defendant may argue that the damage was caused by an external event rather than their own fault.

Examples:

extraordinary natural event;

unavoidable external event;

third-party conduct;

claimant's own conduct.

The critical question is whether the external event legally breaks the causal connection between the defendant's conduct and the damage.

The historical Civil Cassation No. 99/1995 is particularly useful for understanding this causation analysis.

33. Difference Between Fault, Damage and Causation

A claimant should therefore avoid treating these concepts as interchangeable.

34. Six Most Important Case Principles

35. Conclusion

The basic concept of fault in UAE civil law can be summarized as follows:

Fault is legally relevant wrongful or negligent conduct that, when sufficiently connected to legally recognized damage, can result in civil liability and compensation.

The practical analysis is:

Duty → Conduct → Fault/Breach → Causation → Damage → Evidence → Liability → Compensation

The most important point is that fault alone does not automatically determine the amount of damages. UAE courts examine the entire chain of responsibility, including causation, evidence, expert findings, the injured person's contribution, third-party conduct and the nature of the loss.

The cases discussed above—particularly Civil Cassation 99/1995, Civil Cassation 434/448/2007, Commercial Cassation 215/2020, Commercial Cassation 767/2021, Civil Cassation 647/2021, Commercial Cassation 1012/1023/2022, Commercial Cassation 240/2021 and Commercial Cassation 941/2019—provide a useful framework for understanding how UAE courts approach fault, evidence, causation and civil responsibility.

Note: Several of the older authorities were decided under the former 1985 Civil Transactions Law. They remain useful for understanding UAE jurisprudential principles, but the current Civil Transactions Law effective from 1 June 2026 controls present disputes.
