The UAE has established itself as one of the world’s leading arbitration destinations, hosting internationally recognised centres in both the Dubai mainland and the DIFC. For businesses operating in or through the UAE, understanding the distinctions between the Dubai International Arbitration Centre (DIAC), the DIFC Courts, and the broader legislative framework of Federal Law No. 6/2018 on Arbitration is essential for effective dispute resolution planning. This guide covers the key differences, costs, timelines, and enforcement mechanisms for UAE arbitration proceedings.
- DIAC is the leading onshore UAE arbitration institution, operating under Dubai Decree No. 34/2021 and following the UNCITRAL Model Law framework.
- DIFC Courts offer a common-law judicial system with full English-language proceedings; DIFC arbitral awards can be enforced via DIFC Courts without re-examination of the merits.
- Federal Law No. 6/2018 on Arbitration is the national arbitration statute applicable to onshore UAE arbitrations.
- Seat of arbitration determines which procedural law applies and affects enforcement routes; parties have significant freedom to designate the seat.
- The UAE is a signatory to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards.
- DIAC filing fees start at AED 15,000 for claims up to AED 500,000; average arbitrations take 12–18 months from constitution to award.
Why Choose Arbitration in the UAE?
UAE arbitration offers several key advantages over UAE court litigation for commercial disputes. The arbitration process is private and confidential, which is important for disputes involving trade secrets, sensitive pricing information, or reputational concerns. Parties can choose arbitrators with specific technical or legal expertise, rather than relying on the general judiciary. UAE arbitral awards benefit from the New York Convention — enforceable in 172 signatory countries — and from bilateral enforcement treaties with a further 40+ countries, including most Arab nations. Proceedings can be conducted in English, which is practical for international commercial parties. And unlike UAE court judgments, arbitral awards do not generally require re-litigation on the merits for enforcement abroad.
Federal Law No. 6/2018 on Arbitration: The National Framework
Federal Law No. 6/2018 on Arbitration (the “Arbitration Law”) is the primary legislation governing onshore UAE arbitration proceedings. It is modelled on the UNCITRAL Model Law on International Commercial Arbitration and applies to any arbitration conducted in the UAE where the seat is in the UAE, unless the parties have agreed to apply a different arbitration law. The Arbitration Law covers the formation and validity of arbitration agreements, arbitral tribunal composition, interim measures, conduct of proceedings, making of awards, challenge and setting aside of awards, and recognition and enforcement of both domestic and foreign awards. Courts with supervisory jurisdiction over DIAC arbitrations are the Dubai courts (onshore); courts with supervisory jurisdiction over DIFC-seated arbitrations are the DIFC Courts.
DIAC: Dubai International Arbitration Centre
DIAC is the UAE’s flagship onshore arbitration institution, reconstituted under Dubai Decree No. 34/2021 which merged the former DIAC and the Dubai Chamber’s arbitration function. DIAC operates its own Arbitration Rules (2022 version), which incorporate modern procedural tools including consolidation of related arbitrations, joinder of additional parties, emergency arbitrator procedures, expedited procedure for small claims, and provisions for virtual hearings. DIAC maintains a list of approved arbitrators and a panel of arbitrators with specific expertise in construction, finance, real estate, and technology disputes. DIAC’s administrative headquarters are at the Dubai International Financial Centre, although DIAC is an onshore institution and its awards are enforceable through Dubai’s onshore courts.
DIAC filing fees are calculated on a sliding scale based on the amount in dispute. For claims up to AED 500,000, the filing fee is approximately AED 15,000. For claims between AED 500,000 and AED 5 million, the fee ranges from AED 15,000 to AED 45,000. Above AED 5 million, additional percentage-based fees apply, capped at a maximum administrative fee of around AED 350,000. Arbitrator fees are set by the DIAC Secretariat based on hourly rates or scale rates, and typically represent the largest portion of total arbitration costs. A typical three-arbitrator DIAC panel for a mid-size dispute will cost AED 200,000–500,000 in arbitrator fees alone.
DIFC Courts and DIFC-Seated Arbitration
The DIFC Courts are an independent common-law court system within the DIFC free zone, operating in English under the DIFC Courts Law (DIFC Law No. 10/2004, as amended). While the DIFC Courts themselves are not an arbitration institution, they serve as the enforcement court and supervisory court for arbitrations seated in the DIFC. Arbitrations seated in the DIFC typically use LCIA (London Court of International Arbitration) rules under the DIFC-LCIA Arbitration Centre (now known simply as the DIFC Arbitration Centre following the LCIA’s partial withdrawal from the joint venture).
A key advantage of DIFC-seated arbitration is the DIFC Courts’ streamlined enforcement process. A DIFC arbitral award can be enforced in the Dubai onshore courts without re-examination of the merits through the DIFC-Dubai “conduit” mechanism — a unique feature not available to purely onshore arbitrations and not commonly available in other jurisdictions. This makes DIFC-seated arbitration particularly attractive for disputes likely to require enforcement against assets held in Dubai’s onshore jurisdiction.
DIAC vs DIFC-Seated Arbitration: Comparison
| Feature | DIAC (Onshore Dubai) | DIFC-Seated Arbitration |
|---|---|---|
| Governing Law | Federal Law No. 6/2018 | DIFC Arbitration Law |
| Supervisory Court | Dubai Courts (onshore) | DIFC Courts |
| Language | Arabic and/or English | English (default) |
| Enforcement Route (Dubai assets) | Dubai Courts execution | DIFC Courts → Dubai Courts conduit |
| Average Timeline | 12–18 months | 12–24 months |
| Filing Fee (AED 500k claim) | ~AED 15,000 | ~USD 5,000–10,000 (LCIA scale) |
Seat of Arbitration: Why It Matters
The “seat” of arbitration is a legal concept — it refers to the juridical home of the arbitration, determining which procedural law applies, which courts have supervisory jurisdiction, and (in the case of ad hoc arbitrations) where the award is considered to have been “made” for enforcement purposes. The seat does not necessarily determine where hearings physically take place; virtual and multi-venue hearings are common. Parties can — and should — expressly designate the seat in their arbitration agreement. Failing to do so invites disputes about which law governs procedural issues, which courts have jurisdiction to grant interim relief, and which enforcement regime applies.
For UAE businesses, the most common seat choices are Dubai (onshore), DIFC (offshore but within Dubai’s geography), and ADGM (Abu Dhabi). International counterparties often prefer London, Paris, or Singapore as neutral seats, which are fully enforceable via the New York Convention.
New York Convention and Enforcement of Foreign Arbitral Awards
The UAE acceded to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards in 2006 with a reservation of reciprocity (meaning UAE courts will enforce awards from other New York Convention signatory states). A party seeking to enforce a foreign arbitral award in the UAE must apply to the competent UAE court with an original or certified copy of the arbitral award, an original or certified copy of the arbitration agreement, and certified Arabic translations of both. UAE courts will refuse enforcement only on the limited grounds specified in Article V of the New York Convention (procedural defects, arbitrability, public policy). Commercial enforcement timelines in Dubai and Abu Dhabi courts are typically 6–18 months.
Abu Dhabi: ICC and ADCCAC
Abu Dhabi hosts the Abu Dhabi International Arbitration Centre (previously known as the Abu Dhabi Commercial Conciliation and Arbitration Centre, ADCCAC) and serves as a seat for ICC (International Chamber of Commerce) arbitrations administered from the ICC’s regional office. The ICC is particularly popular for high-value international oil and gas, construction, and finance disputes with counterparties from non-Arab jurisdictions who prefer an internationally recognised institution with a strong track record of enforcement globally.
Frequently Asked Questions
Can I include an arbitration clause in any UAE commercial contract?
Yes. Arbitration clauses are valid and enforceable in most UAE commercial contracts, including supply agreements, joint venture agreements, distribution contracts, and real estate sale agreements. Federal Law No. 6/2018 requires the arbitration agreement to be in writing (including electronic form) and signed by parties with legal capacity. Certain disputes — such as some criminal matters and labour disputes — may not be arbitrable under UAE law.
How do DIAC’s expedited procedures work?
DIAC’s 2022 Rules include an Expedited Procedure for disputes where the amount in controversy does not exceed AED 1 million or where both parties agree to use it. Under the Expedited Procedure, the case is decided by a sole arbitrator, time limits are shortened, and the final award must be issued within six months of the tribunal’s constitution. Filing fees for the Expedited Procedure are lower than standard proceedings.
Can I get interim relief in UAE arbitration?
Yes. The UAE Arbitration Law authorises arbitral tribunals to issue interim measures including asset preservation orders, evidence preservation orders, and security for costs orders. Parties may also apply to UAE state courts for interim relief in support of arbitration proceedings without waiving their right to arbitrate — a significant improvement introduced by Federal Law No. 6/2018 over the previous arbitration framework.
Are DIAC awards enforceable outside the UAE?
Yes. DIAC awards, as UAE arbitral awards, are enforceable in all 172 New York Convention signatory countries subject to the procedural requirements and limited grounds for refusal under Article V. In practice, DIAC awards are routinely enforced in England, the US, Germany, France, India, Singapore, and other major commercial jurisdictions.
What is the average total cost of a DIAC arbitration?
For a mid-sized commercial dispute with a claim value of AED 5–10 million, total DIAC arbitration costs (filing fees, arbitrator fees, administrative costs, hearing venue costs) typically run AED 250,000–600,000, not including legal representation fees. Legal fees for both parties can add a further AED 200,000–500,000 per side depending on the complexity of the proceedings.
