Civil Law and UAE Arbitration under UAE Arbitration Law — Federal Law No. 6 of 2018

1. Introduction

The UAE's principal federal legislation governing onshore arbitration is Federal Law No. 6 of 2018 Concerning Arbitration. The law is substantially based on internationally accepted arbitration principles and the UNCITRAL Model Law. It regulates the entire arbitral process, including:

• arbitration agreements;
• arbitrator appointment and independence;
• jurisdiction of the tribunal;
• interim measures;
• arbitral procedure;
• evidence and hearings;
• arbitral awards;
• correction and interpretation of awards;
• annulment;
• recognition and enforcement; and
• court assistance to arbitration.

The official UAE legislation database continues to identify Federal Law No. 6 of 2018 as the federal Arbitration Law.

A central feature of the legislation is limited judicial intervention. Arbitration is intended to provide a final and binding method of resolving civil and commercial disputes, while courts retain supervisory authority over matters such as jurisdiction, due process, annulment and enforcement.

2. Scope of Federal Law No. 6 of 2018

The law principally applies to arbitration conducted in the UAE, subject to the special legal regimes applicable in places such as the DIFC and ADGM.

It is particularly important to distinguish:

Onshore UAE arbitration

Governed principally by Federal Law No. 6 of 2018.

DIFC arbitration

Governed principally by the DIFC Arbitration Law.

ADGM arbitration

Governed principally by the ADGM Arbitration Regulations.

Consequently, merely stating that an arbitration is "in Dubai" does not always establish which arbitration legislation applies. The seat of arbitration is critical.

The DIFC Courts have repeatedly emphasized the importance of identifying the juridical seat when determining supervisory jurisdiction.

3. Fundamental Principles of the UAE Arbitration Law

Federal Law No. 6 of 2018 is built around several fundamental principles.

1. Party autonomy

Parties can agree to arbitration and determine important aspects of the arbitration.

2. Separability

The arbitration clause is legally separate from the underlying contract.

3. Competence-competence

The arbitral tribunal may determine its own jurisdiction.

4. Equality of parties

Parties must receive equal procedural treatment.

5. Right to be heard

Each party must receive a reasonable opportunity to present its case.

6. Independence and impartiality

Arbitrators must satisfy statutory requirements concerning independence and impartiality.

7. Finality

An award is intended to be binding and enforceable, subject to the statutory annulment and enforcement mechanisms.

8. Limited court intervention

Courts should not routinely interfere with arbitral proceedings.

4. Arbitration Agreement

The arbitration agreement is the foundation of arbitral jurisdiction.

The parties must agree to submit an existing or future dispute to arbitration.

An arbitration agreement may generally appear as:

• an arbitration clause in a contract; or
• a separate arbitration agreement.

The fundamental question is:

Have the parties actually consented to arbitration?

If there is no valid arbitration agreement, the tribunal cannot normally acquire jurisdiction merely because one party wants arbitration.

5. Article 6 — Separability of the Arbitration Agreement

One of the most important provisions is Article 6.

The arbitration clause is treated as an agreement independent from the other contractual provisions.

Therefore:

The invalidity, rescission or termination of the main contract does not automatically invalidate the arbitration clause.

This is the separability principle.

For example, if a construction contract is alleged to be fraudulent or terminated, the tribunal may still have jurisdiction to determine whether that contract was validly terminated.

The arbitration clause does not disappear merely because the underlying contract is disputed.

6. UAE Case Law on Separability

YYY Limited v ZZZ Limited [2017] DIFC ARB 005

Although decided in the DIFC context, this case is useful in understanding the UAE's modern arbitration approach.

The DIFC Court expressly referred to Article 6 of Federal Law No. 6 of 2018 and its principle that an arbitration clause is independent from the underlying contract.

Importance

The principle prevents a party from defeating arbitration simply by alleging:

"The main contract is invalid."

The tribunal can determine the validity of the main contract while the arbitration clause remains operative.

7. Article 8 — Referral from Court Litigation to Arbitration

Article 8 is extremely important where one party starts court proceedings despite an arbitration agreement.

Where a dispute covered by an arbitration agreement is brought before a court, the court should decline to hear the dispute if the defendant invokes the arbitration agreement before making a substantive request or plea, unless the court finds that the arbitration agreement is:

• void; or
• incapable of being performed.

This protects the parties' contractual agreement to arbitrate.

The DIFC Court in Ledger v Leeor specifically discussed Article 8(1) and its relationship with Article II(3) of the New York Convention.

8. Case: Ledger v Leeor [2022] DIFC CA 013

Ledger v Leeor is particularly significant because it involved interaction between:

• the arbitration agreement;
• the Dubai Courts;
• the DIFC Courts;
• Article 8 of Federal Law No. 6 of 2018; and
• the New York Convention.

The case demonstrates that the existence of an arbitration agreement can create important limits on parallel court litigation.

The DIFC Court also emphasized the distinction between:

• the seat of arbitration, and
• the physical location where hearings take place.

Importance

The case demonstrates that determining the seat is fundamental to identifying the appropriate supervisory court.

9. Article 19 — Competence-Competence

Article 19 embodies the principle that the arbitral tribunal may determine its own jurisdiction.

The tribunal can consider objections concerning:

• existence of the arbitration agreement;
• validity of the arbitration agreement;
• scope of the arbitration clause;
• whether the particular dispute falls within the arbitration agreement.

This is known internationally as competence-competence.

The principle avoids unnecessary interruption of arbitration by preliminary court litigation.

10. Case: Dubai Court of Cassation No. 481 of 2025

The Dubai Court of Cassation considered the relationship between the tribunal's jurisdiction and court supervision in the context of competence-competence.

The decision is important because it demonstrates the continuing development of UAE jurisprudence concerning the tribunal's authority to determine jurisdictional questions.

Principle

The existence of a jurisdictional objection does not automatically mean that the ordinary courts should take over the entire dispute.

The arbitration framework provides mechanisms through which jurisdiction can initially be addressed within the arbitral process.

11. Arbitrator Appointment

Federal Law No. 6 of 2018 contains detailed provisions concerning the appointment of arbitrators.

The parties may agree on:

• the number of arbitrators;
• appointment procedures;
• qualifications; and
• institutional appointment mechanisms.

Where the parties fail to agree or an agreed mechanism fails, the competent court can assist in the appointment process.

This prevents an uncooperative party from frustrating arbitration merely by refusing to participate in appointment.

12. Independence and Impartiality of Arbitrators

Arbitrators must be independent and impartial.

An arbitrator should disclose circumstances that could give rise to legitimate doubts about independence or impartiality.

This is particularly important because an improperly constituted tribunal can become a ground for annulment.

Abu Dhabi Court of Cassation — Arbitrator Disclosure Case

Abu Dhabi courts have considered an arbitrator's failure to disclose circumstances relevant to independence and impartiality and treated the issue as sufficiently serious to affect the validity of the arbitral process.

Principle

Arbitration depends not only on party consent but also on confidence in the integrity of the tribunal.

13. Equal Treatment and Right to Present the Case

The tribunal must give each party a genuine opportunity to present:

• claims;
• defences;
• evidence;
• expert material;
• legal submissions; and
• responses to the opposing party.

This is a fundamental element of procedural fairness.

A party cannot normally obtain annulment merely because:

• its evidence was rejected;
• its expert was not believed;
• its argument failed; or
• the tribunal adopted the opponent's interpretation.

There must be a genuine procedural deficiency.

14. Case: Abu Dhabi Court of Cassation No. 1115 of 2024

This is an important modern authority concerning annulment.

The Abu Dhabi Court of Cassation emphasized that Article 53 provides a limited statutory framework for challenging arbitral awards.

The court does not act as an ordinary appellate court reviewing the merits of the arbitration.

Therefore, arguments that merely challenge:

• factual findings;
• evaluation of evidence;
• legal reasoning; or
• the tribunal's interpretation,

do not automatically constitute grounds for annulment.

Importance

This case reinforces the principle:

Annulment is not an appeal on the merits.

15. Article 31 — Tribunal's Power to Determine Procedure

The parties have considerable procedural autonomy.

Subject to mandatory provisions of the law, the parties can agree on procedural rules.

If they do not, the tribunal has significant authority to conduct the arbitration in a manner it considers appropriate.

The tribunal can therefore address:

• pleadings;
• evidence;
• expert reports;
• hearings;
• document production;
• witness examination;
• procedural deadlines.

The essential requirement is fairness and equality.

16. Evidence in UAE Arbitration

Arbitration allows considerable flexibility concerning evidence.

The tribunal may consider:

• documentary evidence;
• witness testimony;
• expert evidence;
• electronic communications;
• contractual records;
• technical evidence.

The UAE's broader evidence framework also recognizes electronic evidence, which is increasingly important in commercial arbitration.

However, the tribunal must remain within the boundaries of procedural fairness.

17. Interim Measures

Federal Law No. 6 of 2018 provides mechanisms for interim and precautionary measures.

These measures can protect the subject matter of arbitration while the final dispute is pending.

Examples include measures designed to:

• preserve evidence;
• protect assets;
• prevent dissipation;
• preserve property;
• maintain the status quo.

The tribunal may in appropriate circumstances request court assistance for implementation.

18. Case: Dubai Court of Cassation No. 657 of 2025

The Dubai Court of Cassation considered an arbitral tribunal's interim measure concerning court proceedings relating to matters within the arbitration.

The decision recognized the tribunal's ability to issue appropriate provisional relief and treated the interim order differently from an ordinary final arbitral award subject to annulment.

Importance

It demonstrates that UAE arbitration law provides tribunals with meaningful procedural powers rather than reducing arbitration to a private version of ordinary litigation.

19. Arbitration Hearings and Virtual Proceedings

Federal Law No. 6 of 2018 provides flexibility in conducting arbitral proceedings.

Modern UAE arbitration has increasingly adopted:

• virtual hearings;
• electronic filings;
• electronic evidence;
• digital communications;
• online procedural conferences.

This flexibility became particularly significant following the global movement toward remote dispute resolution.

The fundamental limitation remains procedural fairness: technological convenience cannot deprive a party of a meaningful opportunity to present its case.

20. Arbitral Award

The tribunal must ultimately issue a reasoned award satisfying the statutory requirements.

The award should determine the matters submitted to arbitration.

The tribunal cannot normally decide disputes that fall outside the arbitration agreement.

This is the principle of jurisdictional limitation.

21. Article 52 — Binding Force of Award

Article 52 provides that an arbitral award rendered under the Arbitration Law is:

• binding on the parties;
• vested with res judicata effect; and
• given the same self-executing force as a judgment,

subject to obtaining the court's confirmation required for enforcement under the statutory framework.

This is one of the strongest expressions of the UAE's commitment to arbitral finality.

22. Case: Dubai Court of Cassation No. 778 of 2025

The Dubai Court of Cassation considered formal requirements relating to signatures on an arbitral award.

The Court rejected the proposition that every page necessarily had to bear the arbitrators' signatures.

Principle

The Arbitration Law should not be interpreted through unnecessary formalism where the statutory requirements for an authentic award are otherwise satisfied.

Importance

The case illustrates the increasingly pro-arbitration and practical interpretation of Federal Law No. 6 of 2018.

23. Annulment under Article 53

Article 53 provides that an objection to an arbitral award must be brought through an action for annulment, or raised during proceedings for confirmation of the award.

The challenging party must establish one of the statutory grounds.

Major grounds include:

1. absence of an arbitration agreement;
2. invalidity or expiry of the arbitration agreement;
3. incapacity;
4. inability to present a defence;
5. improper application of the parties' chosen law;
6. improper constitution of the tribunal;
7. serious procedural defect;
8. award beyond the scope of the arbitration agreement;
9. award rendered outside the permitted time; and
10. other statutory grounds concerning arbitrability and public order.

The court can consider non-arbitrability and UAE public order on its own initiative in the circumstances specified by Article 53.

24. Case: Dubai Court of Cassation No. 1115 of 2024

This case is particularly important for Article 53.

The Court emphasized that annulment proceedings cannot become a disguised appeal.

A party cannot simply argue:

"The tribunal made the wrong decision."

Instead, the party must establish a legally recognized annulment ground.

Importance

This protects the finality and efficiency of arbitration.

25. Article 54 — Annulment Procedure

Article 54 regulates the court's treatment of an annulment action.

The annulment procedure is not intended to create a complete retrial of the underlying dispute.

If an award is annulled because of a procedural or jurisdictional defect, the consequences depend on the particular ground.

In appropriate circumstances, the arbitration agreement itself may survive.

This reflects the broader principle of separability.

26. Case: Dubai Court of Cassation No. 821 of 2023

The Dubai Court of Cassation considered the tribunal's authority concerning legal costs.

The Court partially annulled aspects of an ICC award concerning legal fees because the tribunal's authority to award those particular costs was considered insufficiently established under the applicable framework.

Importance

The case illustrates an important principle:

An arbitral tribunal possesses substantial authority, but its powers remain derived from the arbitration agreement, applicable rules and mandatory law.

27. Case: Dubai Court of Cassation No. 756 of 2024

This later case demonstrated a more institution-friendly approach.

The Court recognized that where parties choose institutional arbitration rules, those rules can form part of the parties' arbitration arrangement.

Therefore, institutional rules concerning costs may provide an appropriate basis for the tribunal's decision.

Importance

The case demonstrates the growing importance of party autonomy and institutional arbitration rules in UAE arbitration.

It also shows that UAE arbitration jurisprudence continues to develop rather than remaining fixed in older formalistic approaches.

28. Case: Dubai Court of Cassation No. 735 of 2024

This case concerned a unilateral/asymmetric arbitration clause.

The Court examined whether the particular contractual arrangement created a sufficiently binding arbitration agreement.

The Court concluded, in the circumstances before it, that the clause did not constitute an enforceable arbitration agreement preventing the UAE courts from exercising jurisdiction.

Importance

The case demonstrates that:

A contractual reference to arbitration is not automatically enough.

There must be a legally effective agreement to arbitrate.

29. Enforcement of Arbitral Awards

The award's finality does not mean that every award automatically becomes executable without judicial procedure.

The Federal Arbitration Law establishes a confirmation/enforcement mechanism.

The competent court examines the award within the statutory framework rather than conducting a complete rehearing.

The court's role is principally supervisory.

30. Foreign Awards

Foreign arbitral awards involve an additional layer.

The UAE is a party to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards.

Therefore, UAE courts generally distinguish between:

Setting aside

The court at the seat of arbitration exercises primary supervisory jurisdiction.

Recognition/enforcement

A court in another country determines whether the foreign award should be recognized and enforced.

This distinction is fundamental to international arbitration.

31. Case: Naqid v Najam [2024] DIFC ARB 004

This case demonstrates the importance of identifying the seat before attempting annulment.

The underlying award had been issued in India. Proceedings were nevertheless brought before the Dubai Courts seeking to challenge it.

The Dubai Court of Appeal held that the UAE courts lacked jurisdiction to annul a foreign award, and the Dubai Court of Cassation subsequently dismissed the appeal.

Principle

The country of enforcement is not automatically the country of annulment.

The primary annulment jurisdiction generally belongs to the courts of the seat of arbitration.

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

Although this was a DIFC case, it is valuable for understanding UAE's plural arbitration structure.

The DIFC Court of Appeal distinguished:

• arbitrability; and
• public policy.

It held that arbitrability for DIFC enforcement purposes was assessed under DIFC law, whereas public policy for enforcement was assessed by reference to UAE public policy.

Importance

The case demonstrates why one must not automatically treat:

UAE mainland law = DIFC law = ADGM law.

They are distinct legal regimes within the broader UAE.

33. Institutional Arbitration

Federal Law No. 6 of 2018 permits parties to choose institutional arbitration.

Important institutions connected with UAE arbitration include:

• DIAC;
• ArbitrateAD;
• international institutions such as ICC and others.

Institutional rules can regulate:

• appointment;
• administration;
• procedural deadlines;
• emergency arbitration;
• costs;
• consolidation;
• joinder;
• expedited arbitration;
• tribunal appointment.

The institutional rules selected by the parties can therefore become an important part of the arbitration agreement.

34. Seat and Supervisory Court

The seat of arbitration determines the juridical connection between the arbitration and the courts.

For example:

Dubai mainland seat

Federal Law No. 6 of 2018 principally applies and Dubai Courts exercise supervisory functions.

DIFC seat

DIFC arbitration legislation and DIFC Courts become central.

ADGM seat

ADGM arbitration legislation and ADGM Courts become relevant.

This is why the phrase:

"Dubai arbitration"

may be inadequate.

The parties should clearly identify the seat.

The DIFC decision in Neville v Nigel illustrates the difficulty created by the expression "Dubai Arbitration" without further specification.

35. Relationship Between Federal Arbitration Law and DIFC

The UAE has multiple judicial systems.

This can create disputes about whether:

• Dubai Courts;
• DIFC Courts; or
• another court

should supervise an arbitration.

Ledger v Leeor illustrates this problem and demonstrates the importance of seat analysis and the relationship between Federal Law No. 6 of 2018 and the DIFC arbitration framework.

The principle is:

The existence of an arbitration institution or a UAE connection does not by itself determine the supervisory court.

36. Eight Important Case Laws — Quick Reference

37. Key Advantages of Federal Law No. 6 of 2018

1. International compatibility

The legislation is substantially aligned with international arbitration principles.

2. Party autonomy

Parties have considerable freedom to structure arbitration.

3. Competence-competence

The tribunal can determine its own jurisdiction.

4. Separability

The arbitration clause survives many challenges to the underlying contract.

5. Limited annulment

Courts do not ordinarily re-hear the merits.

6. Enforcement framework

The law provides a structured mechanism for recognition and enforcement.

7. Modern procedural flexibility

The law accommodates institutional and procedural innovation.

38. Major Limitations

Despite its pro-arbitration character, Federal Law No. 6 of 2018 does not create completely unrestricted arbitral autonomy.

The following remain important:

• mandatory UAE law;
• public order;
• arbitrability;
• proper consent;
• tribunal independence;
• due process;
• jurisdictional limits;
• statutory deadlines;
• proper constitution of the tribunal.

Thus:

Arbitration is autonomous, but it is not legally uncontrolled.

39. Overall Legal Position

The UAE Arbitration Law creates a balance between private autonomy and public judicial supervision.

The structure can be understood as:

Arbitration Agreement
↓
Appointment of Tribunal
↓
Tribunal Determines Jurisdiction
↓
Fair and Equal Proceedings
↓
Arbitral Award
↓
Confirmation/Enforcement
↓
Limited Annulment/Review

The courts therefore remain the guardians of:

• consent;
• jurisdiction;
• procedural fairness;
• arbitrability;
• public policy; and
• enforcement.

But they generally do not act as a second arbitral tribunal.

40. Conclusion

Federal Law No. 6 of 2018 transformed UAE onshore arbitration into a modern, internationally oriented arbitration regime. It protects party autonomy while preserving carefully defined judicial supervision.

The most important principles emerging from the legislation and case law are:

1. A valid arbitration agreement is the foundation of jurisdiction.
2. The arbitration clause is separable from the underlying contract.
3. The tribunal may determine its own jurisdiction.
4. Parties must receive equal treatment and a fair opportunity to present their case.
5. Arbitrators must be independent and impartial.
6. Arbitral awards are binding and have res judicata effect. 
7. Annulment is restricted to statutory grounds and is not a general appeal.
8. Courts should not ordinarily re-evaluate the tribunal's factual findings or evidence.
9. The seat determines the primary supervisory and annulment jurisdiction.
10. The distinction between onshore UAE, DIFC and ADGM arbitration is essential.

The cases of Ledger v Leeor, YYY v ZZZ, Dubai Cassation Nos. 735/2024, 756/2024, 821/2023, 778/2025, 657/2025 and 481/2025, Abu Dhabi Cassation No. 1115/2024, and Naqid v Najam collectively demonstrate the UAE judiciary's increasingly pro-arbitration approach while maintaining safeguards for jurisdiction, due process and public policy.

In essence, Federal Law No. 6 of 2018 seeks to make arbitration final enough to be commercially useful, but supervised enough to preserve the legitimacy of the UAE judicial system.
