Civil Law and UAE Commercial Contract Disputes

1. Introduction

A commercial contract dispute in the UAE arises when businesses disagree about the creation, interpretation, performance, breach, termination, payment, or enforcement of a commercial agreement.

Common examples include disputes concerning:

sale and purchase agreements;

distribution agreements;

supply contracts;

construction contracts;

service agreements;

agency agreements;

franchise agreements;

investment agreements;

lease and commercial-property contracts;

financing arrangements;

technology contracts;

joint-venture agreements; and

settlement agreements.

The important feature of UAE commercial contract law is that general civil-law principles and specialised commercial legislation operate together.

As of 2026, the general contractual framework is the Federal Decree by Law No. 25 of 2025 promulgating the Civil Transactions Law, which entered into force on 1 June 2026. Its Article 113 expressly describes a contract as the binding concurrence of offer and acceptance and provides that the contract constitutes the law governing the contracting parties, subject to amendment or rescission by mutual agreement or legal grounds. (UAE Legislation)

Commercial transactions are additionally governed by Federal Decree-Law No. 50 of 2022 on the Commercial Transactions Law, together with specialised legislation applicable to particular industries or contracts. (UAE Legislation)

2. Meaning of a Commercial Contract Dispute

A commercial contract dispute may arise at any stage:

Formation → Interpretation → Performance → Breach → Termination → Damages → Enforcement

For example:

Company A agrees to supply 10,000 units to Company B.
Company A supplies only 5,000 units.
Company B refuses to pay the remaining invoice.
Company A claims payment.
Company B claims breach and damages.

The court may have to determine:

Was there a valid contract?

What exactly did each party promise?

Was the contract performed?

Who breached it?

Was the breach material?

Did the breach cause damage?

Can the contract be terminated or rescinded?

What compensation is available?

3. Current UAE Legal Framework

A. Civil Transactions Law 2025

The current Civil Transactions Law is Federal Decree by Law No. 25 of 2025.

It modernises the general law of obligations and contracts and replaced the former 1985 Civil Transactions Law from 1 June 2026. The UAE Government describes the new law as a comprehensive framework reorganising rights and obligations and modernising contractual rules. (UAE Legislation)

Its general contract provisions apply to both named and unnamed contracts unless specialised legislation provides otherwise. Article 115 expressly preserves special contractual rules contained in the Civil Transactions Law or other legislation. (UAE Legislation)

B. Commercial Transactions Law 2022

Federal Decree-Law No. 50 of 2022 is the principal federal Commercial Transactions Law. (UAE Legislation)

It operates alongside the Civil Transactions Law for commercial relationships.

C. Evidence Law

Federal Decree-Law No. 35 of 2022 on Evidence in Civil and Commercial Transactions governs documentary, electronic, expert and other forms of evidence.

This is particularly important in commercial litigation because disputes often depend upon:

invoices;

purchase orders;

emails;

electronic signatures;

accounting records;

expert reports;

bank records; and

digital communications.

The Evidence Law specifically regulates expert reports and requires them to identify the assignment, work performed, documents/evidence considered, technical analysis and conclusions. (UAE Legislation)

D. Civil Procedure Law

Federal Decree-Law No. 42 of 2022 on Civil Procedure governs litigation, jurisdiction, service, appeals, interim measures and enforcement.

4. Basic Principle: Contract Is the Law of the Parties

One of the fundamental UAE principles is:

Pacta sunt servanda — agreements must be respected.

Under Article 113 of the current Civil Transactions Law, a contract constitutes the law governing the contracting parties and ordinarily cannot be rescinded or amended except by mutual agreement or for legally recognised reasons. (UAE Legislation)

Therefore, when a commercial dispute reaches court, the first question is normally:

What did the parties actually agree to?

The court does not normally rewrite a commercially inconvenient bargain simply because one party later regrets it.

5. Formation of Commercial Contracts

A commercial contract generally requires:

1. Offer

One party proposes contractual terms.

2. Acceptance

The other party accepts the offer.

3. Capacity

The parties must have the required legal capacity and authority.

4. Subject matter

The subject must be legally permissible and sufficiently identifiable.

5. Lawful purpose

The transaction cannot violate mandatory law, public order or public morals.

6. Required form

Where legislation requires a particular form, the parties must comply with it.

The current Civil Transactions Law recognises consensual, formal and real contracts and distinguishes negotiated contracts from contracts of adhesion. (UAE Legislation)

6. Interpretation of Commercial Contracts

Contract interpretation is often the central issue.

The current Civil Transactions Law provides an important distinction:

Clear wording

Where contractual wording is clear, interpretation should not depart from it merely to discover a different common intention.

Ambiguous wording

Where interpretation is genuinely required, the court seeks the parties' common intention, considering the nature of the transaction and the honesty and trust expected between contracting parties in accordance with commercial custom. (UAE Legislation)

Therefore:

Clear contract → apply wording

Ambiguous contract → determine common intention

7. Commercial Custom

Commercial contracts frequently contain technical terminology.

For example:

FOB;

CIF;

delivery terms;

industry standards;

banking practices;

construction standards;

trade practices.

Commercial custom may assist the court in determining the meaning and performance of contractual obligations where the written agreement does not fully answer the issue.

8. Good Faith

Good faith is an important civil-law concept.

A party should not:

deliberately frustrate contractual performance;

exploit a contractual provision dishonestly;

conceal material circumstances where disclosure is required;

manipulate contractual mechanisms solely to injure the other party.

However, good faith does not mean that a court can simply disregard clear contractual terms.

The distinction is:

Good faith controls contractual conduct; it does not automatically rewrite the bargain.

9. Reciprocal Commercial Contracts

Many commercial contracts are bilateral/synallagmatic contracts.

For example:

Seller: deliver goods.

Buyer: pay price.

Both parties have obligations.

The current Civil Transactions Law expressly recognises bilateral contracts where each contracting party undertakes obligations toward the other. (UAE Legislation)

This creates an important defence:

A party may sometimes resist performance where the other party has failed to perform its corresponding obligation, depending upon the applicable statutory and contractual rules.

10. Breach of Commercial Contract

A breach may occur through:

A. Non-performance

The promised obligation is not performed.

B. Late performance

The obligation is performed after the contractual deadline.

C. Defective performance

The party performs, but improperly.

D. Partial performance

Only part of the obligation is performed.

E. Anticipatory refusal

A party clearly indicates that it will not perform.

F. Breach of ancillary duties

For example:

confidentiality;

reporting;

cooperation;

exclusivity;

quality-control obligations.

11. Material Breach

Not every contractual violation justifies termination.

The court may ask:

How serious was the breach?

Did it affect the purpose of the contract?

Was the breach repeated?

Was the breach capable of cure?

Did the innocent party suffer damage?

Did the contract specify consequences?

Did the innocent party accept previous breaches?

This is particularly important for long-term commercial contracts.

12. Termination and Rescission

A commercial contract may potentially be terminated or rescinded where:

a party commits a legally sufficient breach;

a contractual termination clause is properly invoked;

mutual termination occurs;

a statutory ground exists; or

another legally recognised ground applies.

The court must distinguish between:

ordinary contractual termination

and

judicial rescission/cancellation

and

automatic termination under a contractual clause.

The consequences may differ.

13. Case Law 1 — Federal Supreme Court Commercial Cassation Nos. 84 and 178 of 2020

Judgment: 7 April 2020

This is a particularly useful authority on reciprocal contractual obligations.

The dispute involved a lease/investment arrangement. The court considered whether the tenant's failure to pay justified cancellation when the lessor had itself failed to provide the premises in a condition enabling proper use.

The Federal Supreme Court held that the adequacy of the grounds for termination or cancellation must be assessed in light of the parties' respective performance. Where the lessor had not properly enabled use of the premises, the tenant's non-payment could not simply be treated in isolation. (eLaws)

Principle

A party's alleged breach must be assessed in the context of the other party's reciprocal obligations.

Importance

This case is useful for:

termination;

reciprocal obligations;

non-performance;

leases;

commercial contracts;

cancellation.

Memory

84 & 178/2020 = Reciprocal Obligations.

14. Case Law 2 — Federal Supreme Court Commercial Cassation No. 941 of 2019

Judgment: 24 March 2020

This authority is important for legal characterisation of contractual liability.

The UAE Supreme Court emphasised that the court is responsible for giving the dispute its correct legal characterisation rather than simply accepting the legal labels used by the parties.

Where a contractual relationship exists, contractual liability will generally be the primary framework, although circumstances can potentially engage tort principles where their requirements are independently satisfied.

Principle

The court determines the true legal character of the dispute from the facts and relationship between the parties.

Importance

This prevents a claimant from changing the legal characterisation merely to obtain a different remedy.

Memory

941/2019 = Legal Characterisation.

15. Case Law 3 — Federal Supreme Court Civil Cassation No. 79 of 2020

Judgment: 17 February 2020

Although the dispute was not exclusively a commercial-contract case, it establishes an important contractual-evidence principle.

The Court held that an admission can relieve the opposing party from proving an admitted right where the admission is certain, serious and intended to be binding.

It also held that a material defence capable of changing the outcome must be considered by the trial court. Failure to address such a defence can result in deficient reasoning and violation of the right of defence. (eLaws)

Application to commercial contracts

Suppose a company admits:

“Yes, we owe the amount, but only because the goods were delivered in accordance with the contract.”

The court cannot necessarily extract only the first part and ignore the qualifying contractual defence.

Principle

A contractual admission must be considered as a whole, and material contractual defences must be addressed.

Memory

79/2020 = Admission + Material Defence.

16. Case Law 4 — Federal Supreme Court Civil Cassation No. 647 of 2021

Judgment: 20 September 2021

This case established an important rule concerning judicial reasoning.

The Federal Supreme Court stated that a judgment must demonstrate that the court understood the facts and evidence and examined the material aspects of the dispute.

Particular attention must be given to a defence that could change the outcome, especially where it is supported by documents. (eLaws)

Commercial-contract application

Suppose a supplier produces:

delivery records;

invoices;

correspondence;

inspection certificates.

The buyer produces documents alleging defective delivery.

If those documents could change the outcome, the court must meaningfully consider the material evidence and defence.

Principle

Material contractual evidence cannot simply be ignored.

Memory

647/2021 = Reasoned Judgment + Material Evidence.

17. Case Law 5 — Federal Supreme Court Commercial Cassation No. 240 of 2021

Judgment: 4 May 2021

This authority concerns expert evidence, which is extremely important in commercial-contract disputes.

Where a court relies upon an expert report and a party raises material objections capable of affecting the conclusion, those objections must be properly considered.

The court may need to examine the objections or return the matter to the expert where appropriate.

Commercial application

This is particularly relevant to disputes involving:

construction contracts;

accounting;

supply contracts;

loss calculations;

engineering defects;

financial claims.

Principle

A court cannot treat an expert report as unquestionable when material objections capable of affecting the result have been raised.

Memory

240/2021 = Expert Report + Material Objection.

18. Case Law 6 — Federal Supreme Court Commercial Cassation No. 453 of 2021

Judgment: 31 May 2021

This case concerned judicial receivership as interim protection in a commercial dispute.

The Court treated receivership as a temporary protective measure requiring a serious dispute and imminent danger, with the court assessing the evidence and circumstances.

The case is useful for commercial contracts because contractual disputes can create risks requiring interim protection before final judgment.

Example

A joint venture dispute arises and one party controls the company's commercial assets.

The other party may seek protective measures rather than waiting years for the final judgment.

Principle

Interim relief may protect contractual rights where a serious dispute and sufficient urgency/danger are established.

Memory

453/2021 = Receivership + Interim Protection.

19. Case Law 7 — Federal Supreme Court Commercial Cassation No. 882 of 2019

Judgment: 28 January 2020

This case concerned the decisive oath as an evidentiary mechanism.

The Court held that a litigant may tender the decisive oath where the legal conditions are satisfied, and judicial refusal cannot simply be arbitrary or unjustified. (eLaws)

Commercial-contract application

This can become relevant where a contractual fact cannot otherwise be satisfactorily established and the statutory conditions for the decisive oath are met.

Principle

Commercial-contract disputes remain subject to the procedural and evidentiary mechanisms available under UAE law.

Memory

882/2019 = Decisive Oath.

20. Case Law 8 — Federal Supreme Court Civil Cassation No. 880 of 2021

Judgment: 15 November 2021

This case is important for damages and loss of opportunity.

The Court recognised that additional compensation for proven material damage may be available and that damages may include present and future losses where sufficiently established.

It also addressed the possibility of compensating a missed opportunity where the necessary elements are proved.

Commercial-contract application

A breach of a commercial contract might cause:

lost profits;

loss of business opportunity;

future financial loss;

additional expenses.

But the claimant must establish the necessary causal and evidentiary connection.

Principle

Contractual damages must be connected to demonstrable loss and causation rather than mere speculation.

Memory

880/2021 = Future Damage + Lost Opportunity.

21. Case Law Summary

22. Damages in Commercial Contract Disputes

A successful claimant may potentially seek compensation for legally recoverable loss.

The basic analytical structure is:

B-D-C-P

B — Breach

Was there a contractual breach?

D — Damage

Did the claimant actually suffer loss?

C — Causation

Was the loss caused by the breach?

P — Proof

Can the loss be established with admissible evidence?

23. Examples of Commercial Contract Damages

Potential claims may include:

Direct financial loss

Example:

A supplier wrongfully refuses to deliver goods, forcing the buyer to purchase replacement goods at a higher price.

Additional expenses

Example:

A contractor's breach forces the customer to incur additional completion costs.

Lost profits

Possible where adequately established and legally recoverable.

Loss of opportunity

Possible where the missed opportunity is sufficiently established rather than speculative.

Consequential losses

Their recoverability depends on applicable law, contract terms, causation and proof.

24. Liquidated Damages

Commercial contracts frequently contain clauses such as:

“The contractor shall pay AED 50,000 for each week of delay.”

Such clauses can become highly contentious.

The court may have to consider:

Was the clause validly incorporated?

Was there actually a breach?

Was the delay attributable to the contractor?

Did the customer contribute to the delay?

Does the contract permit adjustment?

Is the claimed amount consistent with the applicable law?

Therefore, a liquidated-damages clause does not mean that every stated amount will automatically be awarded regardless of the circumstances.

25. Force Majeure and Unforeseen Events

Commercial contracts may contain force-majeure provisions covering events such as:

natural disasters;

governmental restrictions;

war;

embargoes;

major supply-chain disruptions;

extraordinary events.

The court will examine:

contractual wording;

whether the event falls within the clause;

whether performance was actually prevented;

causation;

mitigation;

notice requirements; and

consequences specified in the contract.

The new Civil Transactions Law also modernises rules concerning contracts of works and unforeseen circumstances affecting contractual equilibrium. (UAE Legislation)

26. Commercial Contract and Expert Evidence

Expert evidence is particularly important in:

Construction disputes

defective works;

delay;

variation orders;

completion costs.

Accounting disputes

unpaid invoices;

profits;

commissions;

financial reconciliation.

Supply disputes

quantity;

quality;

delivery;

defective goods.

Technology disputes

system performance;

implementation failures;

technical specifications.

The UAE Evidence Law expressly structures the expert's work and requires a reasoned technical report. (UAE Legislation)

27. Electronic Commercial Contracts

Modern commercial contracts may be concluded or performed electronically.

Relevant evidence can include:

emails;

electronic purchase orders;

electronic signatures;

digital invoices;

electronic payment records;

ERP records;

WhatsApp communications;

cloud documents.

The UAE Evidence Law contains specific provisions concerning electronic evidence, making authenticity and integrity particularly important.

A party should therefore preserve:

Original electronic record → metadata where relevant → communication chain → authentication → expert verification if disputed.

28. Contract Interpretation: A Practical Example

Suppose a contract states:

“Delivery shall occur within 30 days.”

The buyer argues:

“30 days means calendar days.”

The seller argues:

“30 days means working days.”

The court may examine:

wording;

contract definitions;

industry custom;

surrounding provisions;

parties' course of dealing;

commercial purpose.

Under the current Civil Transactions Law, clear wording receives priority, while ambiguity may require examination of common intention, transaction nature, honesty/trust and relevant custom. (UAE Legislation)

29. Termination Example

Suppose:

Company A supplies machinery to Company B.

B repeatedly fails to pay.

A terminates the agreement.

B argues:

“A had previously accepted late payments.”

The court may examine:

payment history;

contractual termination clause;

notices;

warnings;

seriousness and repetition of breach;

whether A waived or merely tolerated previous defaults;

actual outstanding amounts.

The issue is therefore not simply:

“Was there late payment?”

It is:

Was there a legally sufficient breach justifying the contractual consequence claimed?

30. Set-Off and Counterclaims

Commercial disputes frequently involve competing monetary claims.

Example:

Seller claims: AED 1 million unpaid invoices.

Buyer counterclaims: AED 400,000 damages for defective goods.

The court may need to examine:

validity of both claims;

contractual obligations;

invoices;

delivery records;

expert evidence;

causation;

applicable set-off rules.

This can substantially reduce the amount ultimately payable.

31. Arbitration Clauses

Many commercial contracts contain arbitration clauses.

The dispute may therefore involve:

Contract → Arbitration agreement → Tribunal → Award → Enforcement

Important questions include:

Is there a valid arbitration agreement?

Does it cover the dispute?

Is the clause incorporated by reference?

Who are the parties to it?

Was the arbitration properly commenced?

Was the tribunal constituted correctly?

Can the resulting award be enforced?

The presence of an arbitration clause therefore adds a separate procedural layer to commercial-contract disputes.

32. Jurisdiction Clauses

Commercial contracts may also contain:

UAE court jurisdiction;

a particular Emirate's courts;

foreign courts;

arbitration;

institutional arbitration.

A court may need to determine whether the jurisdiction clause is valid, applicable and sufficiently connected to the dispute.

33. Important Distinction: Contractual Liability vs Tort Liability

A commercial dispute may involve both contractual and tortious allegations.

Contractual liability

Focuses on:

What did the parties promise each other?

Tort liability

Focuses on:

Did one party unlawfully cause damage independently of contractual performance?

The UAE Supreme Court's jurisprudence, including Commercial Cassation No. 941/2019, emphasises the importance of correctly characterising the relationship and claim.

This distinction affects:

burden of proof;

limitation;

remedies;

causation;

applicable statutory provisions.

34. Common Defences in Commercial Contract Litigation

A defendant may argue:

1. No valid contract

The alleged agreement was never concluded.

2. Lack of authority

The person signing lacked authority.

3. Invalidity

The agreement violates mandatory legal requirements.

4. Performance

The defendant already performed.

5. Payment

The amount has already been paid.

6. Counter-breach

The claimant breached first or failed to perform its reciprocal obligation.

7. Force majeure

Performance was prevented by a qualifying event.

8. No damage

The claimant suffered no legally recoverable loss.

9. No causation

The alleged loss was caused by something else.

10. Limitation

The claim was filed after the applicable limitation period.

35. Practical Litigation Framework

For a UAE commercial-contract dispute, use:

C-C-B-E-D-R

C — Contract

Identify the agreement.

C — Clauses

Identify payment, termination, jurisdiction and dispute-resolution provisions.

B — Breach

Identify exactly what obligation was violated.

E — Evidence

Collect documents, electronic evidence and expert material.

D — Damage

Calculate actual legally recoverable loss.

R — Remedy

Determine whether the appropriate remedy is payment, damages, performance, termination, rescission or interim protection.

36. Exam-Oriented Formula

Remember:

F-I-R-E-C-R

F — Facts
I — Issue
R — Rule
E — Evidence
C — Case Law
R — Remedy

For a commercial contract question, write:

Contract → Interpretation → Performance → Breach → Causation → Damage → Remedy

37. Key Principles for UAE Commercial Contract Disputes

A valid contract binds the parties.

Clear contractual language is highly important.

Ambiguous provisions may require examination of common intention and commercial context.

Reciprocal obligations must be considered together.

A material breach may justify termination where the applicable legal requirements are satisfied.

The court determines the proper legal characterisation of the dispute.

Material evidence and defences must be addressed.

Expert evidence is particularly important in technically or financially complex disputes.

Damages require proof of legally recoverable loss and causation.

Interim measures can protect commercial interests while litigation continues.

Arbitration and jurisdiction clauses can substantially alter the dispute-resolution process.

Older case law must be read carefully because the Civil Transactions Law changed from the former 1985 regime to the 2025 Law effective 1 June 2026. (UAE Legislation)

38. Conclusion

UAE commercial contract disputes are governed by a combination of contractual autonomy, mandatory statutory rules, commercial legislation, civil-law principles, evidence rules and procedural law.

The central judicial inquiry is usually:

What was agreed, what was performed, what was breached, what damage resulted, and what remedy does the law permit?

The most useful case-law principles are:

84 & 178/2020 — reciprocal contractual obligations;

941/2019 — correct legal characterisation;

79/2020 — admissions and material defences;

647/2021 — reasoned consideration of material evidence;

240/2021 — expert evidence and objections;

453/2021 — interim commercial protection;

882/2019 — evidentiary oath;

880/2021 — damages and lost opportunity.

Final revision formula:

Contract → Interpretation → Performance → Breach → Evidence → Causation → Damage → Remedy

This is the basic structure for analysing almost any UAE commercial contract dispute.
