Civil Law and UAE Mandatory Legal Provisions

1. Introduction

Mandatory legal provisions are rules of UAE law from which parties cannot freely contract out. They are different from supplementary/default provisions, which generally apply only when the parties have not agreed otherwise.

The principle is especially important in contracts. Parties enjoy substantial contractual freedom, but that freedom ends where a mandatory rule, public order, public morals, or another non-derogable statutory requirement begins.

The UAE has now moved to the Federal Decree-Law No. 25 of 2025 promulgating the Civil Transactions Law, which entered into force on 1 June 2026 and repealed Federal Law No. 5 of 1985.

A particularly important current provision is Article 34 of the 2025 Civil Transactions Law, which states that what is established by a mandatory provision prevails over a contractual condition. The new law also expressly restricts contractual conditions that conflict with law, public order or public morals.

2. Meaning of Mandatory Legal Provisions

A mandatory provision is a statutory rule that parties cannot exclude, waive, modify or defeat by private agreement.

Simple example

Suppose the law says:

“A particular statutory protection must apply to a particular transaction.”

The parties cannot validly write:

“The parties agree that this statutory protection shall not apply.”

If the statutory rule is genuinely mandatory, the statutory rule prevails.

Basic principle

Mandatory law > contractual term

This principle protects interests considered sufficiently important that the legislature does not leave them entirely to private choice.

3. Mandatory Provisions Under the Current UAE Civil Transactions Law

The current Civil Transactions Law contains an important interpretive rule in Article 34:

A matter established by a mandatory provision prevails over a condition.

This is significant because the new law preserves the basic hierarchy that existed under the former Civil Code, while restructuring the legislation.

The new law also provides in Article 184 that contractual conditions are permissible only when they are not contrary to:

1. law;
2. public order; or
3. public morals.

If a contractual condition violates those limitations, the condition itself is void. The contract may also be annulled if it is established that the parties would not have entered into it without that condition.

4. Mandatory Rules and Public Order Are Related but Not Identical

This distinction is very important.

Mandatory rule

A mandatory rule is a rule that the parties cannot contract out of.

Public order

Public order is broader. It concerns fundamental legal, social, economic or institutional interests protected by the legal system.

Therefore:

Every public-order rule may operate as a restriction on contractual freedom, but not every statutory provision should automatically be treated as a public-order rule.

This distinction has become particularly important in UAE arbitration and DIFC litigation.

In Nihan v Nicholas & Niaz, the DIFC Court of Appeal stressed that merely because a subject falls within an area mentioned as public policy under UAE law does not automatically mean that every dispute connected with that subject is non-arbitrable.

5. Sources of Mandatory Legal Provisions

Mandatory provisions can arise from several sources.

A. Federal legislation

For example:

• Civil Transactions Law
• Commercial Companies legislation
• Labour legislation
• Consumer protection legislation
• Arbitration legislation
• Data protection legislation
• Real-estate legislation
• Procedural legislation

B. Emirate-level legislation

Particular matters may also be governed by laws enacted within an Emirate, subject to the constitutional distribution of legislative powers.

C. Constitutional principles

The UAE Constitution establishes important public-law foundations, including respect for the Constitution, laws, public order and public morals.

D. Special legislation

A specific statute may impose requirements that prevail over a general contractual provision.

E. Public-order principles

Courts may refuse to give effect to arrangements that fundamentally conflict with UAE public order.

6. Contractual Freedom Is Not Absolute

The UAE civil-law system recognizes contractual autonomy.

However, contractual freedom operates within the limits prescribed by law.

The parties may generally decide:

• price;
• payment mechanism;
• delivery arrangements;
• allocation of commercial risks;
• contractual procedures;
• applicable law, where legally permissible;
• dispute-resolution arrangements, subject to mandatory jurisdictional and arbitrability rules.

But they cannot simply contract away every statutory requirement.

Example

A contract may say:

“The parties waive all statutory rights.”

That sentence does not automatically eliminate mandatory statutory rights.

The court must identify:

1. what statutory right is involved;
2. whether the relevant provision is mandatory;
3. whether waiver is legally permitted;
4. whether public order or public morals are engaged;
5. whether the provision applies to the particular relationship.

7. Effect of a Contractual Term Contrary to Mandatory Law

There are several possible consequences.

1. The contractual term may be ineffective

The statutory rule prevails.

2. The term may be void

Under Article 184 of the current Civil Transactions Law, a condition contrary to law, public order or public morals may itself be void.

3. The whole contract may be affected

If the parties would not have entered the contract without the invalid condition, Article 184 allows the possibility of annulment of the contract.

4. A court may refuse enforcement

Where enforcement would require violation of a mandatory rule or fundamental public policy, the court may refuse to give effect to the relevant arrangement.

5. The court may apply the statutory rule instead

The court can replace the contractual arrangement with the legally required consequence where the legislation so provides.

8. Mandatory Rules and Jurisdiction

Mandatory provisions are particularly important in jurisdiction disputes.

Parties cannot necessarily choose any court simply because their contract says so.

In Sky News Arabia FZ-LLC v Kassab Media FZ (LLC) [2016] DIFC CA 010, the dispute involved arguments concerning mandatory UAE provisions, jurisdiction, commercial-agency legislation and the relationship between contractual choice and statutory jurisdictional rules. The judgment expressly considered the former Civil Code Article 31 principle that a mandatory provision takes precedence over a contractual stipulation.

The case also demonstrates an important qualification: a rule being mandatory in one legal system does not necessarily mean that it applies in a legally distinct free-zone jurisdiction where the relevant federal legislation has been constitutionally excluded.

9. Mandatory Provisions and DIFC

The UAE contains different legal jurisdictions.

The DIFC is a particularly important example.

The DIFC Courts have repeatedly explained that federal UAE procedural legislation does not simply apply inside the DIFC in the same way as it applies in the onshore courts.

In Lural v Listran & Lokhan [2021] DIFC CA 003, the Court of Appeal confirmed that the UAE Civil Procedure Law did not apply in the DIFC and that DIFC jurisdiction was determined by the applicable DIFC framework.

Thus, when analysing a mandatory provision, the first question should always be:

Which legal system governs the dispute?

Only after that can the court determine whether the particular provision is mandatory and applicable.

10. At Least 6 Important UAE Case Laws

Case 1: Sky News Arabia FZ-LLC v Kassab Media FZ (LLC) [2016] DIFC CA 010

Principle

The case is important for the relationship between mandatory provisions, contractual terms and jurisdiction.

The appellant relied upon the former Civil Code Article 31 and argued that mandatory UAE legislation should prevail over contractual jurisdiction provisions.

Importance

The case demonstrates that:

• statutory rules can override contractual arrangements;
• jurisdictional provisions can raise mandatory-law issues;
• the court must determine which legal regime actually applies.

Case 2: Investment Group Private Limited v Standard Chartered Bank [2015] DIFC CA 004

This case is important for understanding mandatory jurisdictional rules and the special status of UAE free zones.

The DIFC Court of Appeal accepted that jurisdictional provisions of the UAE procedural system can involve public-order considerations, but that did not mean the same provisions automatically controlled the DIFC. The statutory and constitutional framework establishing the DIFC had to be respected.

Principle

A rule may be mandatory within one UAE jurisdiction without automatically overriding the legally established autonomy of another UAE jurisdiction.

This is a crucial distinction in UAE law.

Case 3: Lural v Listran & Lokhan [2021] DIFC CA 003

The DIFC Court of Appeal considered the relationship between the UAE Civil Procedure Law and the DIFC.

It confirmed that the UAE Civil Procedure Law 1992 did not apply within the DIFC and that DIFC jurisdiction was determined under the Judicial Authority Law.

Principle

Mandatory application of a statute depends on its territorial and institutional scope.

Importance

This prevents an overly broad argument that every federal procedural rule is automatically applicable throughout every UAE jurisdiction.

Case 4: Egan & Eggert v Eava & Efa [2013] DIFC ARB 002

The DIFC Court examined the concept of UAE public order.

The judgment discussed former Civil Code Article 3, which described public order as including matters such as personal status, governance, freedom of trade, circulation of wealth, private ownership and other fundamental rules of society.

Principle

Public order represents fundamental interests of the legal system and can restrict private contractual autonomy.

Importance

The case is particularly useful when distinguishing:

ordinary statutory rules → mandatory provisions → public-order principles.

Case 5: Fletcher I LLC & Fletcher III LLC v Florance Logistic Solutions [2015] DIFC ARB 002

The DIFC Court considered the legislative structure surrounding arbitration and UAE public policy.

It noted that certain DIFC arbitration and judicial-authority provisions form part of the UAE's broader legislative machinery within their respective scopes.

Principle

A mandatory legal rule must be analysed according to:

• its source;
• its scope;
• the jurisdiction in which it operates;
• the subject matter to which it applies.

Importance

The case illustrates that the concept of mandatory law cannot be separated from the UAE's multi-level legal structure.

Case 6: Nihan v Nicholas & Niaz [2024] DIFC CA 012

This is one of the most useful modern authorities on the relationship between mandatory provisions, public policy and arbitrability.

The Court explained that merely identifying a subject as falling within an area mentioned in Article 3 of the former Civil Code did not automatically establish that disputes concerning that subject were non-arbitrable.

The Court also distinguished domestic public policy from the narrower public-policy test applicable to enforcement of arbitral awards.

Principle

Not every infringement of mandatory law automatically amounts to a violation of public policy.

The public-policy defence in award enforcement is narrower and requires a sufficiently serious conflict with fundamental principles of justice and fairness.

Case 7: Korek Telecom Company LLC v Iraq Telecom Limited [2024] DIFC CA 016

The DIFC Court of Appeal considered UAE public order in considerable detail.

The Court explained that Article 3 of the former UAE Civil Code contained a non-exhaustive description of public order. It also emphasized that public policy in the context of enforcement of an arbitral award must not simply be equated with every mandatory rule of domestic law.

Principle

There is an important difference between:

“This statutory rule is mandatory”

and

“Violation of this rule makes enforcement contrary to UAE public policy.”

The second proposition requires a substantially higher threshold.

Case 8: Okeke v Obike [2025] DIFC ARB 039

The DIFC Court again applied a narrow approach to public policy in arbitration.

The Court stated that the public-policy ground is engaged only where recognition of an award would fundamentally offend basic and explicit principles of justice and fairness or require abandonment of core legal fundamentals.

Principle

A party cannot convert every alleged statutory error into a public-policy objection.

Case 9: Earlene v Earl [2014] DIFC CFI 011

The DIFC Court considered freedom to contract and choice of governing law.

The Court recognized contractual freedom but also explained that the parties' choice of law is subject to limitations where the selected law conflicts with public policy or public morals.

Principle

Choice of law is not unlimited.

Party autonomy operates inside the mandatory framework of the relevant legal system.

11. Important Distinction: Mandatory Law vs Public Policy in Arbitration

This is a common examination issue.

The Nihan and Korek Telecom decisions are particularly useful for this distinction.

12. Mandatory Provisions and Public-Order Rules

The former Civil Code's Article 3 described public order in broad terms, including personal status, governance, freedom of trade, circulation of wealth, private ownership and other fundamental foundations of society.

The constitutional framework also requires respect for the Constitution, laws, public order and public morals.

Consequently, a court will not normally treat a contractual clause as controlling merely because the parties voluntarily agreed to it.

13. Mandatory Provisions in Commercial Contracts

They can arise in areas such as:

Corporate law

A shareholders' agreement cannot necessarily eliminate statutory requirements concerning:

• corporate authority;
• registration;
• directors' duties;
• shareholder protections;
• mandatory filings.

Agency law

Special commercial-agency rules may impose requirements that cannot simply be avoided by contract drafting.

Employment

Employment legislation contains statutory protections that may not be contractually excluded where the legislation makes them mandatory.

Consumer transactions

Consumer-protection provisions may restrict contractual attempts to eliminate statutory consumer rights.

Construction

Certain statutory liabilities can operate independently of contractual limitation clauses.

Real estate

Registration and ownership rules can involve mandatory statutory requirements.

Arbitration

Parties have substantial autonomy, but mandatory requirements concerning:

• arbitrability;
• procedural fairness;
• enforcement;
• public policy;

remain relevant.

14. How Courts Determine Whether a Rule Is Mandatory

A useful five-step approach is:

Step 1 — Identify the statutory provision

Find the exact provision relied upon.

Step 2 — Examine its wording

Look for language indicating that the provision cannot be excluded or modified.

Step 3 — Examine its purpose

Ask what interest the legislation protects.

Step 4 — Determine territorial and subject-matter scope

A rule may be mandatory but applicable only to a particular:

• jurisdiction;
• transaction;
• person;
• industry;
• type of relationship.

Step 5 — Examine the contractual term

Determine whether the contract:

• contradicts the statute;
• merely supplements it;
• attempts to waive it;
• or operates consistently with it.

15. Effect of Mandatory Provisions on Party Autonomy

The relationship can be summarized as:

Party autonomy

↓

Contractual freedom

↓

Statutory restrictions

↓

Mandatory provisions

↓

Public order and public morals

Thus, UAE civil law does not eliminate contractual freedom. Instead, it places contractual freedom inside a statutory framework.

16. Practical Example

Suppose Company A and Company B conclude a contract containing:

“No statutory provision shall apply to this agreement unless expressly reproduced in the contract.”

If a particular UAE statute contains a mandatory provision applicable to the relationship, this clause cannot simply eliminate it.

The court would ask:

1. Is the statutory provision mandatory?
2. Does it apply to the parties?
3. Does it apply to this transaction?
4. Does the contractual clause conflict with it?
5. Is the clause itself void?
6. Does invalidity affect only the clause or the entire contract?

Under current Article 184, a contractual condition contrary to law, public order or public morals can itself be void, with possible consequences for the whole contract where the condition was essential to the parties' consent.

17. Effect of the 2026 New Civil Transactions Law

This is particularly important for current UAE research.

Federal Decree-Law No. 25 of 2025 came into force on 1 June 2026 and repealed Federal Law No. 5 of 1985.

The new legislation expressly provides in Article 34 that a matter established by a mandatory provision prevails over a contractual condition.

Article 184 further provides a direct mechanism for dealing with contractual conditions contrary to law, public order or public morals.

Therefore, for current mainland UAE contracts and disputes, the 2025 Civil Transactions Law should be the starting point, while older cases applying the 1985 Civil Code should be used carefully as authorities on continuing principles rather than assuming that every old article number remains current.

18. Key Legal Principles from the Case Law

The cases collectively establish several important propositions:

1. Contractual freedom is not absolute.
2. A genuine mandatory statutory rule prevails over an inconsistent contractual term.
3. Mandatory law and public policy are not synonymous.
4. Not every breach of mandatory law automatically creates a public-policy violation.
5. Public policy is particularly narrowly applied when used to resist enforcement of an arbitral award.
6. Mandatory rules must be analysed according to their jurisdictional and statutory scope.
7. DIFC legislation cannot simply be displaced by assuming that every UAE federal rule applies inside the DIFC.
8. A contractual choice of law remains subject to applicable public-policy limitations.
9. A court must distinguish between an invalid contractual condition and invalidity of the entire contract.
10. The current Civil Transactions Law expressly preserves the superiority of mandatory provisions over inconsistent contractual conditions.

19. Examination / Revision Points

Definition

Mandatory legal provisions are statutory rules from which parties cannot validly contract out.

Main current provision

Article 34, Federal Decree-Law No. 25 of 2025: a matter established by a mandatory provision prevails over a contractual condition.

Contractual conditions

Article 184: conditions contrary to law, public order or public morals are void; in appropriate circumstances, the contract itself may be annulled.

Main distinction

Mandatory provision ≠ automatically public policy.

Important cases

1. Sky News Arabia v Kassab Media — mandatory law and contractual jurisdiction.
2. Investment Group v Standard Chartered — mandatory jurisdictional rules and DIFC autonomy.
3. Lural v Listran & Lokhan — UAE CPC does not automatically apply in DIFC.
4. Egan & Eggert v Eava & Efa — UAE public order.
5. Fletcher v Florance Logistic Solutions — legislative framework and public policy.
6. Nihan v Nicholas & Niaz — mandatory law, arbitrability and public policy.
7. Korek Telecom v Iraq Telecom — distinction between mandatory law and public-policy enforcement.
8. Okeke v Obike — narrow public-policy threshold.
9. Earlene v Earl — contractual freedom subject to public policy.

20. Conclusion

Mandatory legal provisions are a fundamental limitation on contractual autonomy in UAE civil law. Parties are generally free to structure their contractual relationships, but they cannot use a private agreement to defeat a statutory rule that the legislature has made non-derogable.

The current Federal Decree-Law No. 25 of 2025, effective from 1 June 2026, expressly reinforces this principle through Article 34 and regulates unlawful contractual conditions through Article 184.

The case law also establishes an important qualification: a mandatory provision should not automatically be equated with public policy. Particularly in arbitration, the public-policy exception is applied more narrowly and generally requires a fundamental conflict with the legal system's basic principles.

In short:

Contractual freedom is the rule; mandatory law is the statutory boundary; public order is a fundamental limitation; and courts determine whether a particular provision is truly non-derogable by examining its wording, purpose, scope and applicable legal system.
