Legal Framework Governing Arbitration and Burden of Proof in the UAE
Primary Sources of Arbitration Law
The UAE arbitration landscape is governed by a combination of federal legislation, ministerial resolutions, and international agreements. The most critical statutory instruments include:
- Federal Law No. 6 of 2018 (UAE Arbitration Law), modeled after the UNCITRAL Model Law and regulating the conduct of arbitration proceedings, including evidentiary matters.
- Cabinet Resolution No. 57 of 2018 on the Executive Regulations of Civil Procedure Law, which also influences evidentiary procedures by cross-reference.
- Federal Decree-Law No. 42 of 2022 on the Civil Procedure Code (as amended), providing further clarification on procedural aspects.
In addition, specific rules of major UAE-based arbitral institutions—such as the Dubai International Arbitration Centre (DIAC) and the Abu Dhabi Global Market Arbitration Centre (ADGM)—supply institutional standards for evidentiary burdens and proof.
The UAE Ministry of Justice and Regulatory Oversight
Interpretation and enforcement of these laws are supervised by the UAE Ministry of Justice and relevant arbitration centers. These are the definitive regulatory authorities, ensuring that arbitral processes and evidentiary responsibilities align with national legal standards as published in the Federal Legal Gazette.
Key Principles of Burden of Proof in UAE Arbitration
Defining Burden of Proof in the UAE Context
In the UAE, the burden of proof (onus probandi) is the obligation to prove disputed facts to the satisfaction of the arbitral tribunal. Typically, the party asserting a claim or raising an affirmative defense carries the evidentiary burden.
Article 33(1) of the UAE Arbitration Law confirms: “the arbitral tribunal may require either party to provide proof as it deems necessary and may order the submission of documents, evidence, or witnesses as appropriate.”
Standard of Proof: What Is Required?
The UAE arbitration standard is generally a balance of probabilities (preponderance of evidence), rather than “beyond reasonable doubt” (which is reserved for criminal matters). However, arbitration panels have significant latitude to assess the sufficiency and credibility of evidence based on the facts of each case, and may invoke Sharia principles in specific contexts.
Allocation of Burden of Proof in Commercial vs. Employment Arbitration
While the basic principle is that claimants bear the burden, in some specialized areas such as employment or consumer disputes, recent ministerial guidelines and court practices may require the respondent employer or service provider to demonstrate compliance with statutory duties.
| Arbitration Type | Who Bears Burden | Key Relevant Laws |
|---|---|---|
| Commercial Arbitration | Claimant (usually plaintiff) | Federal Law No. 6 of 2018; DIAC Rules |
| Employment Arbitration | Employer (re certain statutory rights) | UAE Labour Law (Federal Decree-Law No. 33 of 2021), Cabinet Resolutions |
How the Burden of Proof May Shift During Arbitration
Primary vs. Secondary Burdens
The evidentiary burden may shift as proceedings evolve:
- Initial Burden: The claimant must first present a prima facie (at-first-view) case with supporting documents or witness statements.
- Shifted Burden: If this threshold is met, the burden can shift to the respondent, who must then disprove or counter the claimant’s assertions with its own evidence.
Examples of Shift in Burden
For example, in a construction dispute, once the contractor (claimant) demonstrates that it completed a milestone per the contract, the employer (respondent) must prove any alleged deficiencies or contractual breaches. The tribunal enjoys broad discretion to manage this dynamic—even summoning additional evidence or experts as needed (per Article 35 of UAE Arbitration Law).
Procedural Tools for Managing Burden of Proof
UAE tribunals apply IBAR (Inquisitorial, Balanced, Active, Responsive) management by ordering document production, appointing independent experts, or taking oral testimony, as appropriate. The parties must be prepared for pro-active evidence management and to address any evidentiary gaps during hearings.
Comparison: UAE Civil Law Practice vs. Common Law Approaches
While the UAE is fundamentally a civil law jurisdiction, its arbitration framework increasingly incorporates international best practices—especially concerning the burden and standard of proof. Understanding the practical distinctions is vital for multinational companies and legal teams.
| UAE Civil Law | Common Law |
|---|---|
| Relies on written evidence, party-supplied documents, and statutory guidance; tribunal is proactive in evidence management. | Heavily dependent on oral testimony, cross-examination, and adversarial discovery; parties lead proof and responses. |
| No formal doctrine of legal “disclosure” or wide-ranging discovery; evidence must be specifically requested or tribunal-ordered. | Disclosure/discovery processes are a cornerstone; broader investigatory tools are available to parties. |
| Formal rules for notarized documents and expert evidence under civil codes. | Flexible rules, burden assessment may fluctuate based on case law and prior judgments. |
Recent Legal Updates: 2025 and the Future of UAE Arbitration
Key 2025 Updates Affecting Burden of Proof
New amendments in 2023 and 2024, especially the updates to Federal Decree-Law No. 42 of 2022 and executive guidance from the Ministry of Justice, further clarify the burden of proof in arbitration:
- Wider Tribunal Powers: Recent clarifications grant arbitral tribunals greater autonomy to order the production of key documents and to sanction parties that obstruct or withhold evidence.
- Digital Evidence Recognition: Cabinet Resolution No. 57 (2018) and Ministry guidelines now provide that digital records (emails, electronic signatures, encrypted contracts) are admissible, subject to authenticity.
- Sanctions for Frivolous Submissions: Tribunals may impose adverse inferences or cost penalties for non-compliance with evidentiary orders.
Comparative Table: Old vs. New Law on Evidentiary Burdens
| Pre-2018 Legislation | 2018 UAE Arbitration Law & 2024 Updates | |
|---|---|---|
| Evidentiary Orders | Limited clarity, judges led process | Tribunal has explicit powers to request and compel evidence (Art. 33/35) |
| Electronic Evidence | Rarely recognized | Admissible; regulated standards for digital authenticity |
| Sanctions for Non-Compliance | Unclear or rare | Adverse inferences and cost orders explicitly available |

Case Studies: Applying Burden of Proof in Real UAE Arbitration
Case Study 1: Cross-Border Commercial Dispute
Scenario: A UAE distributor claims damages from an international supplier for non-conforming goods. The distributor provides purchase orders and delivery notes. The tribunal then shifts the burden to the supplier, demanding evidence of product compliance checks and quality certifications. The supplier’s failure to provide these is interpreted as a presumption in favor of the distributor, resulting in a favorable award.
Case Study 2: Employment Arbitration
Scenario: An employee alleges arbitrary dismissal. Under the UAE Labour Law (Federal Decree-Law No. 33 of 2021), the employer is compelled to show written warnings and documented performance reviews. Failure to do so leads the tribunal to presume wrongful termination.
Case Study 3: Digital Evidence in IP Dispute
Scenario: A technology company alleges IP theft; evidence depends on timestamped email correspondence and logs. The tribunal scrutinizes digital authenticity, referencing Cabinet Resolution No. 57 of 2018 for accepted standards. Strict digital evidence protocols swing the award in favor of the party able to demonstrate chain of custody and authenticity.
Risks of Non-Compliance and Legal Exposure
Immediate and Long-Term Risks
Misunderstanding evidentiary burdens exposes organizations to:
- Adverse Awards: Failure to meet burdens often results in dismissal of claims or acceptance of the opponent’s version of facts.
- Increased Costs: Non-compliance with tribunal orders can lead to cost penalties per Article 39 of the UAE Arbitration Law.
- Reputational Harm: Publicized cases of non-compliance or failed arbitration may impact commercial relationships and investor confidence.
- Criminal or Regulatory Sanctions: Providing false evidence or deliberate concealment may invite referral to UAE authorities, especially under anti-fraud statutes.

Conclusion: Shaping a Proactive Approach in UAE Arbitration
The burden of proof remains one of the most pivotal yet often misunderstood aspects of UAE arbitration. With sweeping updates to applicable laws and the increasing complexity of cross-border disputes, organizations must reassess their internal protocols and litigation strategies. The most effective approaches involve early evidence preparation, rigorous compliance with arbitral directions, and adoption of state-of-the-art digital record-keeping systems.
Looking forward, these legal developments will shape the UAE’s arbitration environment by promoting transparency, efficiency, and international credibility. Businesses, HR managers, and legal professionals must stay informed and invest in compliance frameworks to maintain a strategic advantage and minimize the risk of costly disputes.
