Civil Law and UAE Construction Liability Rules

1. Introduction

UAE construction liability is based on a combination of contractual liability, statutory liability, professional liability, tortious liability, and the special regime of decennial liability for serious structural defects.

As of 1 June 2026, the principal legislation is Federal Decree-Law No. 25 of 2025 (New Civil Transactions Law), which replaced the 1985 Civil Transactions Law. The new law substantially preserves the traditional UAE construction-liability framework while renumbering and modifying several provisions. In particular, the former Articles 880–883 concerning decennial liability are now principally reflected in Articles 821–824. (Noura Lawyers)

A construction dispute may therefore involve several separate questions:

Was the contractor's work defective?

Was there delay or defective performance?

Who was responsible for the design?

Did the consultant properly supervise the works?

Does the defect threaten structural stability or safety?

Does statutory decennial liability apply?

What damages resulted?

Are contractual limitation, notice, or dispute-resolution provisions applicable?

Can liability be transferred to a subcontractor?

Is arbitration required?

2. Meaning of Construction Liability

Construction liability means the legal responsibility of a contractor, engineer, architect, consultant, developer, subcontractor or other project participant for failure to perform construction obligations properly.

Liability can arise from:

defective construction;

defective design;

negligent supervision;

delay;

abandonment;

non-completion;

failure to follow specifications;

failure to comply with applicable regulations;

damage caused to third parties;

structural failure;

unsafe construction;

failure to rectify defects;

breach of warranties;

breach of contractual obligations.

The important point is that not every construction defect automatically creates decennial liability. Ordinary contractual defects and serious structural/safety defects must be distinguished.

3. Current UAE Legal Framework

The principal framework consists of:

A. Federal Decree-Law No. 25 of 2025

This is the New Civil Transactions Law, effective from 1 June 2026.

Its construction provisions regulate the muqawala or contract-for-work relationship and contain the new decennial-liability provisions.

B. Federal Decree-Law No. 42 of 2022

The Civil Procedure Code governs:

civil proceedings;

expert appointment;

interim measures;

enforcement;

evidence-related procedural matters;

execution of judgments.

C. Federal Law No. 6 of 2018

This governs arbitration where the construction contract contains an arbitration agreement.

D. Contractual documents

Construction liability is also determined by:

FIDIC conditions;

particular conditions;

specifications;

drawings;

bills of quantities;

employer's requirements;

consultant's instructions;

variation orders;

completion certificates;

defects-liability provisions.

UAE construction contracts frequently allocate particular risks contractually, but statutory mandatory rules remain important. (Chambers Practice Guides)

4. Ordinary Contractual Liability

The first level of construction liability is ordinary contractual liability.

A contractor is generally required to perform the work:

according to the contract;

according to specifications;

within the agreed time;

in accordance with approved drawings;

with appropriate workmanship;

and in accordance with applicable contractual obligations.

If the contractor delivers defective or incomplete work, the employer may have contractual remedies depending on the contract and applicable law.

Example

A contractor agrees to install waterproofing according to specified technical standards.

The waterproofing fails because the contractor did not follow the specification.

The employer may claim:

cost of investigation;

rectification costs;

consequential contractual losses where recoverable;

delay-related losses where proved;

other contractual remedies.

This is different from a structural defect triggering decennial liability.

5. Defective Performance

Defective performance can constitute non-performance of a contractual obligation.

A useful comparative authority is Hexagon Holdings (Cayman) Limited v DIFC Authority & DIFC Investments LLC [2020] DIFC CA 003, where the DIFC Court considered contractual non-performance and expressly recognised that non-performance can include defective or late performance. (DIFC Courts)

In construction disputes, therefore, liability does not necessarily depend upon total abandonment.

It can arise from:

performance that technically occurred but did not satisfy the contractual requirements.

6. Decennial Liability

The most distinctive feature of UAE construction law is decennial liability.

Under the former Article 880 and its new equivalent, Article 821, the contractor and engineer/architect can be jointly liable for ten years from delivery for:

total collapse;

partial collapse; or

defects threatening the structural integrity or safety of the building or fixed installation.

The New Civil Code retains this fundamental ten-year regime. (Mayer Brown)

The basic structure is:

Building/fixed installation

↓

Engineer/design + contractor construction relationship

↓

Collapse or serious structural/safety defect

↓

Statutory decennial liability

↓

Ten-year period from delivery

The liability is generally characterised as strict, meaning that the employer does not have to establish ordinary negligence in the same way as in a conventional fault-based claim. (Chambers Practice Guides)

7. Why Decennial Liability Is Important

The regime reflects the UAE legal policy that structural integrity of buildings should receive special protection.

A contractor cannot simply argue:

“The employer accepted the building, therefore I have no liability.”

Similarly, the statutory regime is not ordinarily defeated merely because the employer approved the construction method.

The former Article 880 expressly contemplated liability even where the defect arose from the land itself or the employer consented to the construction. The new regime substantially maintains this approach. (Kayrouz & Associates)

8. Ten-Year Period

The statutory period is generally calculated from delivery/handover of the building or fixed installation.

This is important because:

construction completion is not necessarily the same as legal delivery;

defects may appear after handover;

the defect must fall within the statutory decennial regime;

a separate limitation period applies to bringing the claim.

Under the traditional regime, claims concerning collapse or discovery of the relevant defect are subject to a three-year period. The New Civil Code substantially preserves this structure. (Mayer Brown)

9. Liability of the Contractor

The contractor's liability may arise from:

A. Defective workmanship

Example:

poor reinforcement;

inadequate concrete;

improper structural connections;

defective waterproofing where it affects structural safety.

B. Failure to follow drawings

The contractor may be liable where construction materially departs from approved contractual designs.

C. Use of inappropriate materials

For example, materials that fail contractual or regulatory specifications.

D. Failure to remedy defects

Where contractual defects are identified and the contractor fails to correct them, contractual damages may arise.

E. Structural defects

Serious structural defects can additionally fall within the decennial regime.

10. Liability of the Engineer or Architect

The engineer's liability depends partly on the role assumed.

An engineer may have responsibility for:

design;

structural calculations;

specifications;

supervision;

certification;

inspection;

instructions.

The traditional UAE rule distinguishes an architect/engineer whose role is limited to preparing plans from one who also supervises execution.

The former Article 881 provided that where the architect's work was restricted to preparing plans and excluded supervision, liability was correspondingly limited to defects in the plans. The new legislation retains this basic distinction in its renumbered provisions. (Chambers Practice Guides)

11. Joint Liability of Contractor and Engineer

Where the statutory conditions are satisfied, the contractor and supervising engineer can have joint statutory responsibility.

This is particularly important where a structural defect results from a combination of:

defective design; and

defective construction.

The employer does not necessarily have to divide the structural failure into separate percentages before bringing the statutory claim.

The respective parties may subsequently address contribution or recourse between themselves.

12. Subcontractor Liability

The construction chain commonly looks like:

Employer → Main Contractor → Subcontractor → Supplier

A significant change under the New Civil Code is clarification concerning recourse against subcontractors.

The new regime makes clear that the statutory decennial regime does not simply extend down the contractual chain as between the main contractor and subcontractor. Instead, the contractor's recourse against a subcontractor is principally contractual and requires the appropriate contractual/fault basis. (kennedyslaw.com)

Therefore:

Employer → Contractor

may involve statutory decennial liability.

But:

Contractor → Subcontractor

is treated separately and cannot automatically be converted into a decennial-liability claim merely because the contractor itself has incurred decennial liability.

This makes indemnity, warranty and subcontract drafting particularly important.

13. Can Decennial Liability Be Excluded?

Generally, no.

The UAE statutory regime treats decennial liability as mandatory.

The New Civil Code continues the rule that contractual provisions attempting to exclude or limit this statutory liability are void. The relevant new provision is Article 823. (Noura Lawyers)

Therefore, a clause saying:

“The contractor shall have no responsibility whatsoever for structural defects after completion”

cannot ordinarily defeat the mandatory statutory regime.

However, ordinary contractual liability outside the statutory decennial regime may be subject to contractual allocation and limitations, subject to mandatory-law restrictions.

14. Ordinary Defects vs Decennial Defects

For example:

Defective paint: ordinarily contractual.

Minor defective tiles: ordinarily contractual.

Poor waterproofing: may be contractual, depending on consequences.

Structural foundation failure: potentially decennial liability.

Partial structural collapse: classic decennial-liability issue.

15. Defects Liability Period vs Decennial Liability

These concepts should not be confused.

Defects Liability Period (DLP)

Usually contractual.

It may be:

12 months;

24 months;

another agreed period.

It normally concerns correction of contractual defects.

Decennial Liability

Statutory.

It concerns:

collapse; or

defects threatening structural stability or safety.

It extends for ten years from delivery.

Consequently, expiry of a contractual 12-month defects-liability period does not necessarily eliminate statutory decennial liability for a qualifying structural defect. (Chambers Practice Guides)

16. Construction Delay Liability

Construction liability is not limited to physical defects.

A contractor can also face liability for delay.

Delay may result from:

failure to mobilise;

insufficient labour;

procurement problems;

defective work requiring rework;

failure to comply with drawings;

failure to coordinate subcontractors.

However, delay must be analysed according to the contract.

FIDIC contracts often contain:

extension-of-time provisions;

notice requirements;

liquidated damages;

Engineer determinations;

claim procedures.

17. Panther Real Estate Development LLC v Modern Executive Systems Contracting LLC [2022] DIFC CA 016

This is an important construction authority.

The contract contained FIDIC provisions, including a 28-day notice requirement for contractor claims.

The DIFC Court of Appeal held that the contractual notice mechanism operated as a condition precedent to an extension-of-time/additional-payment claim under the relevant contractual wording. The case also considered the prevention principle and employer-caused delay. (DIFC Courts)

Importance

It demonstrates that:

Even where the employer caused delay, the contractor must comply with contractual claim procedures where the contract makes those procedures mandatory.

It also demonstrates that construction liability depends not only on general civil-law principles but on the precise contractual machinery.

18. Five Real Estate Development LLC v Reem Emirates Aluminium LLC [2020] DIFC TCD 009

This construction dispute concerned delay and defective works.

The Court considered:

extension of time;

employer-caused delay;

contractual notice;

FIDIC provisions;

alleged defective door handles;

evidence concerning rectification costs.

The case demonstrates that a party claiming damages for defective work must provide adequate evidence concerning the defect and the amount of the claimed loss.

It is therefore useful for the principle:

Defect + responsibility + causation + proven quantum

rather than merely:

Defect = automatic damages.

19. Brookfield Multiplex Constructions LLC v DIFC Investments LLC [2016] DIFC CFI 020

This is one of the most important UAE/DIFC construction cases.

The dispute concerned the DIFC Gate Building. A stone slab had fallen from the building's cladding, creating concerns about further failures and safety.

The parties disputed alleged defective workmanship and the appropriate forum for resolving substantive liability.

The DIFC Court dealt with the interaction between:

construction defects;

expert evidence;

urgent inspection;

arbitration;

court assistance;

preservation of evidence.

The Court recognised the distinction between an expert identifying technical deficiencies and the ultimate adjudicator deciding legal questions such as breach and liability. (DIFC Courts)

Principle

Technical expert evidence can establish:

what is defective;

how the defect occurred;

possible causation;

technical consequences.

But the ultimate legal conclusion belongs to the court or arbitral tribunal.

20. Abu Dhabi Court of Cassation — Case No. 293/Judicial Year 3

This is an important traditional authority concerning decennial liability.

The court considered the relationship between delivery and the statutory decennial regime.

The authority is particularly useful for the proposition that decennial liability is directed toward serious defects affecting the soundness and stability of the building rather than every minor construction defect. (Al Tamimi & Company)

Principle

A defect discovered after construction is not automatically a decennial defect.

The defect must fall within the statutory category.

21. Abu Dhabi Court of Cassation — Case No. 721/Judicial Year 3

This authority addresses the scope of compensation under the decennial regime.

The traditional jurisprudence emphasises that contractor/engineer liability under the decennial provisions concerns:

total collapse;

partial collapse;

defects affecting solidity/stability.

It is therefore an important authority for distinguishing structural liability from ordinary defects. (Al Tamimi & Company)

22. UAE Union Supreme Court — Case No. 293/2009

This authority has been cited in UAE construction-law literature concerning the legal character and operation of decennial liability.

It is useful for understanding that the statutory guarantee is imposed by law and is linked to the special construction relationship rather than being simply an ordinary negligence claim. (BSpace)

The case should, however, be read alongside the current 2026 statutory framework because the New Civil Code has replaced the older statutory numbering.

23. UAE Union Supreme Court — Case No. 722/21

This authority is another traditional UAE Supreme Court authority cited in connection with decennial liability.

It is useful in understanding the historical judicial treatment of the statutory construction guarantee and the relationship between contractor and supervising professional. (BSpace)

Again, older case law remains useful for interpretation, but its old article references should not be mechanically treated as the numbering of the 2026 Civil Transactions Law.

24. Ledger v Leeor [2022] DIFC CA 013

This case involved a major construction contract valued at approximately AED 348 million.

The contract incorporated FIDIC conditions together with Particular Conditions that modified the General Conditions.

The dispute demonstrates the importance of examining:

the main contract;

incorporated FIDIC provisions;

Particular Conditions;

contractual allocation of responsibility;

obligations to execute and complete the project;

obligations to remedy defects.

(DIFC Courts)

Principle

Where Particular Conditions modify standard FIDIC provisions, the Particular Conditions must be carefully analysed because they can change the parties' contractual rights and responsibilities.

25. Architeriors Interior Design LLC v Emirates National Investment Co LLC [2024] DIFC TCD 001

This case concerned refurbishment works at Amber Residency.

The dispute included claims relating to:

incomplete works;

defective works;

waterproofing defects;

extension of time;

prolongation;

liquidated damages;

remedial costs.

(DIFC Courts)

The case is particularly useful because it shows that a single construction dispute can contain several different liability categories simultaneously.

For example:

Delay liability

Defective-work liability

Rectification costs

Contractual damages

may all arise in the same project.

26. Recent Dubai Court of Cassation Approach

A recent Dubai Court of Cassation decision discussed decennial liability in the context of a major infrastructure project.

The Court considered expert findings concerning alleged design and supervision defects and ultimately found that the evidence did not establish the structural defects necessary to trigger decennial liability. It also emphasised that later regulatory changes could not simply be used retrospectively to establish that an earlier design was defective. (turtl.tamimi.com)

Important lesson

The existence of a claim labelled “construction defect” does not establish liability.

The claimant must establish the factual and technical foundation for the statutory claim.

27. Expert Evidence

Expert evidence is extremely important in UAE construction disputes.

A construction expert may investigate:

structural calculations;

concrete quality;

reinforcement;

soil conditions;

waterproofing;

foundations;

cracks;

settlement;

façade systems;

mechanical/electrical works;

design compliance;

construction methodology;

causation;

cost of rectification.

The expert's role is especially important because courts generally require technical evidence before making findings concerning complicated construction defects.

Brookfield Multiplex demonstrates the importance of separating technical expert evidence from the ultimate legal determination of breach and liability. (DIFC Courts)

28. Causation

Even where ordinary contractual liability applies, causation is critical.

A claimant should generally establish:

Defect/Breach

↓

Responsibility of defendant

↓

Causal connection

↓

Actual loss

↓

Recoverable damages

For example, if a building has water leakage, the claimant must establish whether the leakage resulted from:

contractor workmanship;

consultant design;

defective materials;

inadequate maintenance;

subsequent alterations;

third-party activity.

A contractor should not automatically be responsible merely because a defect exists somewhere within a project.

29. Design Responsibility

Design responsibility must be examined carefully.

Employer-designed project

The employer or consultant may retain substantial design responsibility.

Contractor-designed project

The contractor may bear broader design obligations.

EPC contract

The contractor may assume extensive responsibility for:

engineering;

procurement;

construction;

commissioning.

Traditional procurement

The consultant may design and supervise while the contractor constructs.

Nevertheless, statutory decennial liability can affect the contractor even where the contractor's contractual role is principally construction, because the statutory regime is specifically designed to protect structural integrity. (Chambers Practice Guides)

30. Ground Conditions

One distinctive feature of the UAE regime is the treatment of ground conditions.

Under the traditional decennial provision, liability could remain even where the collapse or defect resulted from a defect in the land itself.

The New Civil Code substantially retains this statutory approach. (Kayrouz & Associates)

Therefore:

“The soil was defective”

does not necessarily provide a complete defence to a decennial-liability claim.

The contractual allocation of site investigation risk remains relevant to other contractual claims and to recourse between project participants.

31. Employer Consent Is Not Necessarily a Defence

Another important principle is that employer approval does not automatically eliminate statutory decennial liability.

For example:

The employer approves a particular structural method.

Later, a qualifying structural defect threatens the building's safety.

The contractor cannot necessarily say:

“The employer approved it, so statutory liability disappears.”

The mandatory nature of the decennial regime is the reason for this rule. (Kayrouz & Associates)

32. Damage and Remedies

Depending upon the legal basis and facts, construction remedies may include:

repair;

replacement;

cost of rectification;

completion costs;

delay damages;

liquidated damages;

consequential losses where legally recoverable;

termination;

restitution;

compensation;

interest;

arbitration costs;

expert costs.

In a construction dispute, the claimant must distinguish:

Entitlement

Whether there is a legal right to compensation.

Quantum

How much compensation is actually recoverable.

This distinction was particularly visible in cases involving claims for remedial works and defective construction.

33. Liquidated Damages

Construction contracts frequently contain liquidated-delay-damage clauses.

The contractual question is generally:

What amount is payable when the contractor fails to complete by the contractual completion date?

However, employer-caused delay can complicate the analysis.

Panther v Modern Executive Systems is particularly relevant because it discussed employer-caused delay, contractual extension-of-time mechanisms and the relationship between delay and liquidated damages. (DIFC Courts)

34. Prevention Principle

The prevention principle generally concerns circumstances where one party's conduct prevents the other from performing on time.

Examples include:

late drawings;

late access;

delayed approvals;

employer variations;

delayed instructions.

But construction contracts can modify the consequences through express extension-of-time provisions.

The Panther judgment demonstrates that the contractual mechanism must be examined carefully and that a contractor's failure to comply with a contractual notice provision can affect entitlement to relief. (DIFC Courts)

35. Termination for Construction Breach

A construction contract may permit termination for:

abandonment;

prolonged delay;

serious defective work;

insolvency;

failure to comply with contractual notices;

failure to remedy defects.

Termination must be distinguished from decennial liability.

Termination ends or changes the contractual relationship, while a qualifying structural defect may continue to create statutory liability after completion and handover.

36. Arbitration and Construction Liability

Large UAE construction contracts frequently contain arbitration clauses.

The arbitration clause may determine disputes concerning:

delay;

defects;

variations;

payment;

termination;

extension of time;

liquidated damages.

However, court proceedings can still become relevant for:

interim relief;

evidence preservation;

expert inspection;

enforcement;

recognition;

jurisdictional questions.

Brookfield Multiplex illustrates this interaction particularly well: the court dealt with urgent inspection/evidence issues while substantive contractual liability was connected to the arbitration agreement. (DIFC Courts)

37. Practical Liability Matrix

38. Six Core Requirements for a Construction Liability Claim

A useful examination framework is:

1. Identify the legal relationship

Is it:

employer–contractor;

contractor–subcontractor;

employer–consultant;

purchaser–developer;

third party–contractor?

2. Identify the obligation

Was there an obligation concerning:

design;

construction;

supervision;

completion;

repair?

3. Identify the breach or statutory trigger

Was there:

defective performance;

delay;

non-performance;

structural failure?

4. Establish causation

What caused the damage?

5. Establish loss

What financial or physical damage occurred?

6. Select the correct remedy

Possible remedies include:

rectification;

damages;

termination;

specific contractual relief;

statutory decennial compensation.

39. Case-Law Summary

The older UAE cases should be read together with the 2026 New Civil Code, because their reasoning often refers to Articles 880–883 of the repealed 1985 Civil Transactions Law rather than the current Articles 821–824. (Mayer Brown)

40. Key Legal Principles

The major principles can be summarised as follows:

A contractor may be liable for defective or incomplete contractual performance.

Delay can create contractual liability.

Design responsibility depends upon the contractual allocation of design obligations.

Supervising engineers can incur professional and statutory responsibility.

Decennial liability is a special mandatory statutory regime.

Decennial liability concerns collapse or defects threatening structural integrity or safety.

The statutory period is ten years from delivery.

The decennial regime cannot generally be excluded or reduced by contract.

Minor finishing defects are not automatically decennial defects.

Expert evidence is often essential.

Causation and quantum remain important for ordinary contractual claims.

Subcontractor recourse is distinct from the employer's statutory decennial claim under the new law.

FIDIC notice and claim provisions can materially affect contractual entitlement.

Employer-caused delay may affect delay damages, subject to the contract.

Construction liability may be determined through litigation or arbitration depending on the dispute-resolution agreement.

Conclusion

UAE construction liability operates through multiple overlapping layers. Ordinary contractual liability governs defective performance, delay, non-completion and failure to follow specifications. Professional liability may apply to engineers and consultants for defective design or supervision. Above these ordinary rules sits the particularly important decennial-liability regime, which imposes mandatory statutory responsibility on the contractor and relevant engineer for ten years after delivery where a building collapses or suffers a defect threatening its structural integrity or safety. (Mayer Brown)

The 2026 Civil Transactions Law is especially significant because it retains the core decennial regime while clarifying the treatment of subcontractor recourse. Accordingly, a UAE construction-liability analysis should always separate ordinary contractual defects, delay claims, professional negligence/design responsibility, and statutory decennial liability, rather than treating every construction defect as the same type of legal claim.
