Contract law in the UAE governs when an agreement becomes legally binding, how its terms must be performed, and what remedies apply when a party defaults. For most onshore civil and commercial agreements, the central framework is Federal Decree-Law No. 25 of 2025 Promulgating the Civil Transactions Law, effective from 1 June 2026. A valid contract generally requires genuine mutual consent, legally capable parties, a lawful and sufficiently defined subject matter, and a lawful cause. The parties must perform the agreement according to its terms and in good faith. Depending on the breach, the available remedies may include specific performance, suspension, rescission, damages or agreed compensation.
What Is UAE Contract Law?
What is the contract law in UAE? For most contracts outside the UAE’s financial free zones, the principal source is the Civil Transactions Law. Federal Decree-Law No. 25 of 2025 repealed Federal Law No. 5 of 1985 and brought the new law into force on 1 June 2026. Its rules address negotiations, consent, capacity, representation, interpretation, performance, assignment, rescission, impossibility and compensation.
The 2025 law is generally prospective. Contracts and disputes crossing the commencement date require analysis of when the agreement, act, breach or legal effect arose rather than a mechanical replacement of old article numbers. The law also contains conflict-of-law rules: contractual obligations are generally governed by the law expressly chosen by the parties, subject to mandatory rules, public order and special rules such as those applying to immovable property. e Commercial Transactions Law, Evidence Law, Civil Procedure Code, Electronic Transactions and Trust Services Law, Arbitration Law and sector-specific legislation may also apply. The correct analysis depends on the transaction, chosen law and agreed forum.
Essential Elements of a Valid Contract Under UAE Law
For a contract to be legally valid and enforceable under the UAE Civil Transactions Law, it must satisfy several essential legal requirements. If any of these core elements are missing, the agreement may be unenforceable or subject to annulment. Although different types of contracts may require additional formalities, the following elements form the legal foundation of most civil and commercial agreements.
Mutual Consent
A contract is formed when the parties freely agree on its essential terms through a valid offer and corresponding acceptance. Consent must be genuine and free from fraud, coercion, or fundamental mistake that affects a party’s decision to enter the agreement.
Legal Capacity
The parties must have the legal capacity to contract. Individuals who have reached the age of majority and possess full mental capacity may generally enter into binding agreements. Companies must act through duly authorized representatives with the necessary corporate authority.
Lawful Subject Matter
The contract must concern a lawful subject that is clearly defined or capable of being determined. Agreements relating to illegal activities or matters contrary to public order and public morals are generally invalid.
Lawful Cause
Every contract must have a lawful legal purpose. Under UAE civil law, the concept of lawful cause replaces the common law doctrine of consideration in most onshore contracts. An agreement made for an unlawful purpose may be declared void.
The Four Core Principles of Contract Law
Four ideas consistently shape contract law basics in the UAE.
Freedom of Contract
Parties may negotiate their terms, but cannot override mandatory legislation, public order or public morals.
Mutual Consent
A contract depends on corresponding expressions of will. Article 124 requires mutual consent on the essential elements, together with a lawful and sufficiently defined subject matter and lawful cause. Consent must be genuine; mistake, deception, coercion or lack of authority may affect validity or enforceability. # 3. Binding Force
Once a valid and binding agreement is formed, a party cannot normally alter or revoke it unilaterally. Article 232 states that a valid and binding contract may be revoked, modified or rescinded only by mutual consent, litigation or a legal provision. # 4. Good Faith
Article 221 requires performance according to the contract and good faith in contract law, including consequences arising from legislation, custom and the transaction’s nature. How Is a Valid Contract Formed in the UAE?
A contract is not enforceable merely because a document has been signed. Formation requires consent, capacity, lawful content and any formality imposed for the particular transaction.
Offer and Acceptance
Article 125 provides that a contract is formed when an offer is linked to a corresponding acceptance and the parties agree on the essential elements. An offer should be sufficiently clear to show the proposed obligations. Acceptance must correspond with it. ceptance may be expressed through words, writing, a commonly understood gesture, exchange of acts or conduct that clearly indicates consent. Silence is generally not acceptance, although it may have that effect where the parties agreed so, surrounding circumstances clearly indicate consent, prior dealings support it or the offer is solely for the recipient’s benefit. # What Is a Counter-Offer?
Counter offer contract law applies when the recipient does not accept the original proposal exactly. Under Article 125, a response that adds, restricts or modifies the proposed terms is treated as rejection of the original offer and the making of a new offer. A late acceptance after the offer has expired is also treated as a new offer. # Subject Matter and Lawful Cause
The subject matter must exist or be capable of existing, be specified or capable of specification, and be legally permissible. A contract involving unlawful conduct or a purpose contrary to public order may be void or unenforceable.
The Civil Transactions Law uses lawful cause rather than making common-law consideration the universal basis of every onshore contract. The definition of consideration in contract law remains relevant where DIFC, ADGM or another common-law system governs.
Capacity in Contract Law
Capacity in contract law concerns whether a person may enter into a legally effective agreement. Article 84 sets the age of majority at 18 Gregorian years and provides that a person who has reached that age, possesses full mental capacity and is not interdicted has full capacity to exercise civil rights. This corrects the outdated statement that contractual capacity generally begins at 21. company must also act through an authorised representative. Businesses should verify corporate approvals, powers of attorney and signature authority. Pre-Contract Negotiations, Disclosure and Confidentiality
The 2026 framework gives negotiations greater legal importance. Article 121 requires parties to negotiate in good faith. Entering negotiations, conducting them or ending them in bad faith may create liability for actual damage caused, although the loss of expected profit from the uncompleted contract is excluded. Deliberately withholding material information may constitute bad faith. Article 122 requires a party to disclose decisive information that would have prevented the other party from contracting or would have caused it to contract on materially different terms. The parties cannot contract out of that duty, and the affected party may seek annulment. Article 123 protects confidential information obtained during negotiations from unlawful disclosure or use.
Misrepresentation, Fraud and Mistake in UAE Contracts
The validity of a contract depends on informed and genuine consent. Where consent is obtained through deception or other legal defects, the affected party may have the right to challenge the agreement.
Fraud
Fraud involves intentionally misleading another party to induce them to enter into a contract. This may include false statements, concealment of material facts, or dishonest conduct designed to influence the other party’s decision.
Misrepresentation
Misrepresentation occurs when inaccurate information influences a party’s decision to contract. Depending on the circumstances and legal requirements, it may provide grounds for annulment or compensation.
Mistake
A fundamental mistake regarding an essential element of the contract may affect its validity if the mistake materially influenced the parties’ consent.
Coercion
A contract entered into because of unlawful threats or improper pressure may be challenged if the affected party demonstrates that their consent was not freely given
Void and Voidable Contracts Under UAE Law
Not every defective contract has the same legal effect. UAE law distinguishes between contracts that are void from the outset and those that remain valid unless successfully challenged by an affected party.
What Is a Void Contract?
A void contract has no legal effect because it lacks one or more essential legal requirements. For example, a contract involving unlawful activities or an illegal subject matter will generally be treated as void and cannot be enforced.
What Is a Voidable Contract?
A voidable contract is initially valid but may be annulled if one party proves that its consent was affected by fraud, coercion, mistake, or another legally recognized defect. Until annulled, the contract generally continues to produce legal effects.
Grounds for Annulment
A party may seek annulment where legal grounds exist, including:
- Fraud or intentional deception.
- Material mistake affecting consent.
- Unlawful coercion or duress.
- Lack of legal capacity.
- Failure to comply with mandatory legal requirements.
Types of Contracts in the UAE
| Type | Meaning | Example |
| Bilateral contract | Both parties undertake obligations to each other. | A supplier delivers goods and the buyer pays. |
| Unilateral contract | One party promises performance upon completion of a specified act. | A reward offered for returning property. |
| Express contract | Terms are stated orally, in writing or electronically. | A signed consultancy agreement. |
| Implied contract | Agreement is inferred from conduct and circumstances. | Services repeatedly requested and paid under an established course of dealing. |
Express Terms, Implied Terms and Mandatory Rules
Express terms are the provisions the parties state in the signed agreement, schedules, purchase orders, specifications or incorporated documents. Implied terms arise from legislation, custom, the nature of the transaction or established dealings.
Article 221 confirms that contractual obligations are not limited to the literal text. The contract also includes consequences required by law, custom and the nature of the transaction. Article 120 directs interpretation toward justice and good faith, with attention to true intentions, commercial custom and the transactionF’s circumstances.
Exclusion clauses contract law issues arise when a party attempts to restrict liability, remedies or implied obligations. Such clauses should identify the excluded loss, applicable cap, exceptions and relationship with indemnities and insurance. Clauses cannot safely be assumed effective where they conflict with mandatory law, public order, fraud, gross fault or a special statutory protection.
Article 223 also permits adjustment of an unfair adhesion-contract term or exemption of the weaker party.

How Contract Disputes Are Resolved in the UAE
Parties have several options for resolving contractual disputes depending on the agreement and the nature of the dispute.
Negotiation
Many disputes are resolved through direct discussions before formal proceedings begin.
Mediation
An independent mediator assists the parties in reaching a mutually acceptable settlement without imposing a binding decision.
Arbitration
Commercial parties frequently choose arbitration for confidential, flexible, and internationally enforceable dispute resolution.
Court Litigation
Where settlement is not possible, disputes may proceed before the competent UAE courts, which determine liability and appropriate legal remedies according to the applicable law.
Performance of Contracts and Good Faith
A party must perform the agreed obligation in the required manner, place and time. Payment provisions, delivery conditions, service levels, milestones, acceptance procedures and notice requirements should be precise enough to verify performance.
Under Article 222, where reciprocal obligations are due, either party may withhold its own performance if the other party does not perform, subject to the agreement and the circumstances. This is not a general licence to stop work or payment whenever a disagreement occurs; the obligations must be corresponding and due, and wrongful suspension may itself constitute breach. What Is a Breach of Contract Under UAE Law?
Breach of contract UAE law arises when a party fails to perform a due obligation, performs late, performs defectively or acts contrary to the agreement. The claimant must identify the obligation, breach, causation and recoverable loss, while also addressing notices, mitigation, exclusions and limitation periods.
Common breach of contract UAE examples include:
- Failure to pay an invoice or certified amount.
- Non-delivery or late delivery of goods.
- Defective or incomplete services.
- Breach of confidentiality or exclusivity.
- Unauthorised termination.
- Failure to meet a milestone or service level.
Specific Performance
Article 331 generally supports compulsory performance after default where performance remains possible. Where specific performance would be excessively onerous, the court may limit the remedy to compensation if that does not cause substantial prejudice to the creditor. # Damages and Agreed Compensation
Where performance is impossible or the legal requirements are met, compensation may be awarded for proven loss. Article 340 permits the parties to predetermine compensation, but the court may reduce it where it is excessive, the original obligation was partly performed or the creditor contributed to the loss. A higher amount may be claimed where fraud or gross fault is established. e claimant should preserve the contract, notices and evidence proving causation and loss, while taking reasonable steps to mitigate avoidable damage.
Rescission and Suspension
Article 234 allows the non-defaulting party, after giving notice, to seek performance or rescission in a bilateral contract. The court may grant additional time, refuse rescission where the unperformed part is minor or award compensation where justified. Contract Termination Under UAE Law
Contract termination UAE law distinguishes between expiry, completed performance, mutual cancellation, termination under an express clause, judicial rescission and automatic dissolution caused by impossibility.
Mutual Consent
The parties may end or amend the agreement by consent and should record payment, releases and surviving obligations.
Termination for Breach
A material breach does not always permit immediate self-help termination. The agreement may require a default notice and cure period, while Article 234 contemplates notice before seeking performance or rescission. The seriousness of the breach, contractual wording and remedy selected must be reviewed before action is taken. # Automatic Termination Clauses
Article 235 permits the parties to agree that a contract will be automatically rescinded upon non-performance. Notice remains required unless the parties expressly waive it. Careful drafting is needed to distinguish automatic rescission from a right to terminate by notice. # Force Majeure and Impossibility
Article 236 provides that where force majeure makes performance of a reciprocal obligation impossible, the corresponding obligation is extinguished and the contract is automatically rescinded. Partial or temporary impossibility is treated according to its extent and the contract’s nature.
Mere commercial difficulty is not necessarily impossibility. Article 224 separately addresses exceptional, general and unforeseeable circumstances that make performance onerous and threaten serious loss. # Consequences of Termination
Article 237 generally requires the parties to be restored to their pre-contract positions following rescission; where restoration is impossible, compensation may be ordered. Survival clauses should state which obligations continue, including confidentiality, accrued payments, intellectual-property protections and dispute provisions. Assignment and Novation
Assignment in contract law transfers a contractual right or, under the applicable mechanism, a debt. The new Civil Transactions Law distinguishes assignment of rights from assignment of debts.
An assignment of a right may generally occur without debtor consent unless restricted by law, agreement or the obligation’s nature, but effectiveness against the debtor and third parties depends on acceptance or notification. A debt transfer requires the consent prescribed by law, including creditor acceptance for discharge of the original debtor. Novation contract law usually refers to replacing an existing obligation or party with a new one so that the former obligation is discharged. Because novation changes substantive obligations rather than merely directing payment, the agreement should clearly identify what is extinguished, what replaces it and which securities, guarantees or accrued rights survive.
Contract Enforcement in the UAE
Obtaining a favorable judgment or arbitral award is only part of the enforcement process.
Enforcement may involve:
- Filing execution proceedings.
- Identifying the debtor’s assets.
- Freezing assets were legally permitted.
- Enforcing court judgments.
- Enforcing domestic or foreign arbitral awards.
- Recovering outstanding contractual amounts through judicial procedures.
Prompt legal action can improve the likelihood of successful recovery while preserving valuable evidence and enforcement options.
Electronic Contracts and Digital Signatures
An electronic agreement is not invalid merely because it was created or signed digitally. Federal Decree-Law No. 46 of 2021 provides that electronic documents do not lose legal effect because of their electronic form and allows offer and acceptance to be expressed through electronic communications. Automated electronic contracting can also be valid. alified electronic signatures may equal handwritten signatures when statutory conditions are met, and the Evidence Law recognises electronic evidence. The digital contracting process should retain the complete document, identity and authority records, audit trail, timestamps, authentication method, version history and evidence of delivery and acceptance. Certain transactions may still require notarisation, registration, witnessing or another prescribed form.
Contract Language, Arabic Translation and Formalities
A UAE contract may be drafted in English, Arabic or both unless a special rule or authority requires a particular form. For onshore proceedings, Arabic is the official court language, although designated specialised tribunals may use English. Non-Arabic documents may therefore need certified Arabic translation before they can be relied upon. A bilingual contract should identify the prevailing language without ignoring court translation requirements.
Certain powers of attorney, company documents, security arrangements and real-estate instruments may require notarisation, attestation or registration.
Limitation Periods for Contract Claims
The statement that every breach of contract claim generally has a 15-year period is too broad. UAE limitation and non-hearing periods vary according to the claim, parties and governing legislation.
For example, Article 92 of the Commercial Transactions Law applies a five-year period to qualifying obligations between merchants from the date performance falls due, unless a shorter period applies and is subject to the statutory conditions. Other claims may have different periods, including shorter deadlines under sector-specific laws or the contract’s notice machinery. Limitation analysis must identify the claim, due date, dispute forum and contractual time bars before deadlines expire.
DIFC and ADGM Contract Law
DIFC contract law differs from the onshore civil-law framework. The DIFC has its own legal database, including Contract Law DIFC Law No. 6 of 2004 and related laws on implied and unfair terms, damages, obligations, electronic transactions and arbitration.
Parties using a DIFC governing-law or jurisdiction clause should analyse the current consolidated legislation and the DIFC Courts’ jurisdiction rather than assuming the federal Civil Transactions Law applies in the same way. GM is also distinct. Its Application of English Law Regulations 2015 directly apply English common law, including equitable principles, within ADGM’s framework. This can materially affect formation, consideration, interpretation, remedies and precedent. governing-law and forum clauses should identify the chosen law, court or arbitration seat, rules and language.
Cross-Border and International Contracts
International business transactions often require experienced contract drafting lawyers to prepare clear and enforceable agreements.
Businesses should consider:
- Applicable governing law.
- Jurisdiction clauses.
- International arbitration agreements.
- Currency and payment provisions.
- Tax considerations.
- Regulatory approvals.
- Recognition and enforcement of foreign judgments or arbitral awards.
Carefully structured international contracts reduce legal risks and improve enforceability across different jurisdictions.
UAE Labour Law and Limited Contracts
The new labour law for limited contract in UAE is a specialised employment framework rather than a general commercial contract rule.
Federal Decree-Law No. 33 of 2021 requires private-sector employment contracts to cover a defined term, which may be renewed by agreement. MoHRE has confirmed that the law does not impose a maximum cap on that term. arches for UAE labor law limited contract, UAE labour law contract and UAE labour law limited contract resignation should therefore be answered primarily under labour legislation, implementing regulations and MoHRE procedures.
Employment-contract amendments may require the prescribed electronic approval process, and assigning work outside the agreed role generally requires written worker consent except in limited statutory circumstances. Consulting experienced Labour and Employment Lawyers helps businesses and employees ensure compliance with UAE labour laws and reduce the risk of disputes. A breach of contract in UAE labour law may involve unpaid wages, unlawful deductions, notice, restrictive covenants, or premature termination, but the remedies and forums differ from an ordinary business-contract claim.
When Should You Contact a Contract Lawyer?
A contract lawyer, contract attorney or team of contract law lawyers can assist before signature, during performance or after a dispute begins, especially in high-value or cross-border transactions.
Legal support may include contract drafting UAE, negotiation, due diligence, amendment, assignment, termination, settlement and enforcement. A contract enforcement lawyer can assess notices, evidence, urgent protective measures and the most suitable dispute forum. Commercially focused contract law services should address both legal rights and the practical cost of preserving the business relationship.

Frequently Asked Questions About UAE Contract Law
What is the definition of contract law?
Contract law is the legal framework governing enforceable agreements. It determines how promises become binding, how terms are interpreted, what performance is required and which remedies are available after breach.
What is the contract law in UAE?
For most onshore agreements, the Civil Transactions Law is the central framework, supported by commercial, evidence, procedure, electronic-transactions and sector-specific laws. DIFC and ADGM use distinct legal frameworks, so the contract’s governing-law and jurisdiction clauses must be checked.
What are the four principles of contract law?
A practical summary is freedom of contract, mutual consent, binding force and good-faith performance. Each principle is subject to mandatory law, public order and the particular transaction.
Does silence amount to acceptance?
Usually not. Silence may exceptionally indicate acceptance where the parties agreed that result, prior dealings or surrounding circumstances support it, or the offer is solely beneficial to the recipient.
What is a counter-offer under UAE law?
A purported acceptance that adds, restricts or changes the offer is a rejection and a new offer. The first party must accept the revised terms before a contract is formed on that basis.
What remedies are available for breach of contract?
Remedies may include specific performance, suspension of reciprocal performance, rescission and compensation. Notice, causation and evidence remain critical.
Can a party terminate a contract immediately after breach?
Not always. The agreement may require notice and a cure period, and the Civil Transactions Law contains rules governing rescission, automatic clauses and impossibility. Immediate termination without a valid basis may itself be wrongful.
