UAE Arbitration & Dispute Resolution Center: DIAC + DIFC-LCIA License 2026

Updated August 2026.

The United Arab Emirates has established itself as one of the world’s foremost international arbitration hubs, rivaling Singapore, London, and Paris as a preferred seat for complex cross-border commercial disputes. The UAE’s strategic geographic position between Asia, Africa, and Europe, its sophisticated legal free zone jurisdictions (DIFC and ADGM), its 2018 reform of the UAE Arbitration Law, and its 2006 accession to the New York Convention have together created the conditions for a thriving alternative dispute resolution market. In 2025, DIAC, the DIFC’s DAI, and ADGM all reported record caseloads across arbitration, mediation, and adjudication proceedings. This guide covers the complete regulatory and institutional landscape for establishing an ADR or arbitration practice in UAE in 2026.

DIAC: Dubai International Arbitration Centre — 2021 Restructuring and 2022 Rules

The Dubai International Arbitration Centre (DIAC) was comprehensively restructured under Dubai Decree 34/2021, which effectively reconstituted DIAC as a new institution, absorbing the former DIFC-LCIA (Dubai International Arbitration Centre — London Court of International Arbitration) and bringing all Dubai-seated institutional arbitration under a single DIAC umbrella. The DIAC Arbitration Rules 2022 (effective May 2022) govern all proceedings administered by DIAC, replacing both the former DIAC Rules 2007 and the DIFC-LCIA Rules.

Under the DIAC Arbitration Rules 2022, filing fees are 1.5% of the total claim value, with a minimum of AED 5,000 and a maximum of AED 500,000. Arbitrator fees are set by the DIAC Court of Arbitration based on the DIAC Schedule of Costs and the nature of the dispute. DIAC administered over 300 new cases in 2024, with a total disputed amount exceeding AED 10 billion across its caseload. DIAC’s seat of arbitration is Dubai, and its awards are enforceable directly in Dubai Courts and, through the Dubai-DIFC Courts Protocol, across the DIFC jurisdiction.

For ADR practitioners, DIAC accreditation as a DIAC arbitrator requires application to the DIAC Court of Arbitration with evidence of legal qualifications (typically a minimum of 7 years post-qualification experience in relevant practice areas), demonstrated arbitration experience, and compliance with DIAC’s arbitrator conflict-of-interest policies. DIAC maintains a published list of accredited arbitrators available to parties for panel selection.

DIFC Arbitration: DAI and the DIFC Common Law Seat

Following the 2021 restructuring that merged DIFC-LCIA into DIAC, the DIFC Authority established the DIFC Arbitration Institute (DAI) to administer arbitration and other dispute resolution proceedings under DIFC Law. The DIFC Arbitration Law (DIFC Law 1/2008, most recently amended 2021) is based on the UNCITRAL Model Law on International Commercial Arbitration and governs arbitrations where the seat is DIFC.

The DIFC seat remains the most commercially favored seat for international contracts involving DIFC-registered entities, major project finance transactions, and cross-border M&A where parties seek an English common law jurisdiction for dispute resolution. DIFC Courts can directly enforce DIFC-seated arbitral awards without the award ratification step required in UAE mainland courts. The 2022 amendment to DIFC Arbitration Law strengthened third-party funding provisions and emergency arbitrator procedures, aligning DIFC with leading international arbitration seats.

International arbitration institutions including the International Chamber of Commerce (ICC), LCIA, and AAA-ICDR continue to administer cases with DIFC seats, though the ICC is the most common non-DIAC institutional choice for DIFC-seated proceedings. ICC cases with DIFC seats benefit from DIFC Courts’ robust interim measures and award enforcement capabilities while maintaining the procedural framework of the ICC Rules 2021.

ADCCAC and ADGM Arbitration Center: Abu Dhabi Dispute Resolution

The Abu Dhabi Commercial Conciliation and Arbitration Centre (ADCCAC) has been restructured under the Abu Dhabi Judicial Department (ADJD), making ADJD the administering authority for Abu Dhabi-seated institutional arbitration proceedings. ADCCAC handles construction, real estate, and commercial disputes involving Abu Dhabi government entities and private sector parties. Abu Dhabi’s substantial government-linked construction and infrastructure pipeline — driven by ongoing Etihad Rail, ADNOC upstream expansion, and Masdar City projects — generates significant ADCCAC caseloads.

The ADGM Arbitration Centre operates under the ADGM Courts Arbitration Regulations and is a distinct arbitration forum within the Abu Dhabi Global Market free zone. ADGM-seated arbitrations benefit from ADGM Courts’ enforcement capabilities and the ADGM-ADJD enforcement protocol, which enables ADGM arbitral awards to be enforced through Abu Dhabi Judicial Department execution proceedings. ADGM’s growing prominence in financial services dispute resolution — particularly for banking, fund, and fintech matters — reflects the FSRA’s (Financial Services Regulatory Authority) expanding regulatory perimeter.

UAE Arbitration Law: Federal Decree-Law 6/2018 and UNCITRAL Foundation

Federal Decree-Law 6/2018 on Arbitration (the “UAE Arbitration Law”) replaced the arbitration provisions of Federal Law 11/1992 (UAE Civil Procedures Law, Articles 203–218) and established the UAE’s standalone arbitration statute. The 2018 Law is expressly based on the UNCITRAL Model Law on International Commercial Arbitration 2006, bringing UAE mainland arbitration law into alignment with the leading international standard. The 2018 Law applies to all arbitrations seated in the UAE mainland (i.e., outside DIFC and ADGM, which have their own separate arbitration laws).

Key provisions of Federal Decree-Law 6/2018 include: written arbitration agreement requirements (electronic agreements valid); arbitral tribunal composition rules; challenge procedures for arbitrators; interim measures; award requirements (reasoned award mandatory); confidentiality provisions; and the role of UAE courts in supporting arbitration (referral to arbitration on court motion, interim measures from UAE courts in support of arbitration, and award enforcement through UAE court ratification). The Arbitration Law has been broadly welcomed by practitioners as bringing clarity and reliability to the UAE mainland arbitration framework that was previously less certain under the fragmented civil procedure provisions.

New York Convention: Enforcing Foreign Arbitral Awards in UAE

The UAE acceded to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (1958) in 2006. This accession is one of the most commercially significant developments in UAE dispute resolution history, establishing the framework under which foreign arbitral awards — from virtually any international arbitration seat — can be enforced in UAE courts. Prior to 2006, enforcement of foreign arbitral awards in the UAE required navigation of uncertain judicial recognition pathways. Post-accession, enforcement proceeds through an application to the ADJD (for Abu Dhabi matters) or Dubai Courts (for Dubai matters) execution court.

UAE courts have developed a consistent body of practice under the New York Convention enforcement framework. Grounds for refusing enforcement are limited to: invalidity of the arbitration agreement, improper notice to a party, award outside the scope of submission, improper tribunal composition, award not yet binding, public policy violation (UAE concept), and non-arbitrability under UAE law. UAE public policy grounds remain the most invoked defense, though courts have progressively narrowed the public policy exception in recent years. The GCC Riyadh Convention (1983) provides an alternative enforcement mechanism for awards from GCC member state arbitrations within the GCC. For many GCC-seated arbitrations, practitioners may use both the Riyadh Convention and the New York Convention pathways in parallel.

MOJ Mediation Center: Pre-Litigation Mediation Requirement

Federal Decree-Law 40/2023 on Mediation in Civil and Commercial Disputes introduced a mandatory mediation step before litigation can commence for specified categories of civil and commercial disputes at UAE federal courts. The law established the Federal Center for Mediation and Conciliation under the Ministry of Justice UAE (MOJ) and requires claimants to attempt mediation at an MOJ Mediation Center before filing suit in many commercial matters. Mediation proceedings must be completed within 30 days (extendable by agreement). If mediation fails, the claimant receives an exemption certificate enabling court filing.

Dubai Courts established a parallel Dubai Centre for Amicable Settlement of Disputes (CASES) which has been operational since 2009 and handles significant volumes of pre-litigation mediation — particularly real estate, construction, and commercial contract disputes. The ADJD Mediation Center provides equivalent services in Abu Dhabi. For ADR practitioners, the mandatory mediation requirement has substantially expanded the market for accredited mediators, mediation center operators, and med-arb (mediation followed by arbitration) practitioners.

The DIAC Mediation and Other ADR Rules and the DIFC Dispute Resolution Authority’s mediation framework provide structured mediation options within institutional ADR platforms. Establishing a combined mediation, arbitration, and adjudication practice in the UAE — particularly one with DIAC arbitrator accreditation, MOJ mediation center registration, and DIFC practice credentials — positions a firm to serve the full spectrum of UAE commercial dispute resolution demand, which has grown substantially since the 2023 mandatory mediation reform.

Establishing a UAE ADR Institution or Arbitration Practice: Costs

Setting up an ADR institution or arbitration practice in the UAE ranges from AED 500,000–3,000,000 depending on scope, jurisdiction, and institutional ambitions. A standalone arbitration advisory and case management practice (without operating as an institution) costs at the lower end: DIFC or mainland office leasing (AED 50,000–200,000/year), DIAC arbitrator accreditation, MOJ mediation center registration, DED or DIFC legal consultancy license (AED 10,000–30,000), professional indemnity insurance (AED 20,000–100,000), and staff for case administration. Establishing a full ADR institution with administered arbitration capabilities requires substantially higher capital for regulatory approvals, technology infrastructure (case management platform), and staffing a permanent secretariat.

Frequently Asked Questions

What are the DIAC arbitration fees?

DIAC (Dubai International Arbitration Centre) charges filing fees of 1.5% of the total claim value under the DIAC Arbitration Rules 2022, with a minimum fee of AED 5,000 and a maximum of AED 500,000. Arbitrator fees are set separately by the DIAC Court of Arbitration based on the DIAC Schedule of Costs. Additional fees apply for emergency arbitrator applications, challenge proceedings, and consolidated arbitrations. DIAC’s fee structure is designed to make it cost-competitive with ICC and LCIA for mid-size disputes while providing administered institutional support.

Is UAE a party to the New York Convention?

Yes. The UAE acceded to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards in 2006. This enables enforcement of foreign arbitral awards — from virtually any international arbitration seat — in UAE courts (ADJD for Abu Dhabi, Dubai Courts for Dubai) through an application to the execution court. Grounds for refusing enforcement are limited to: invalid arbitration agreement, improper notice, award outside scope of submission, public policy violation (UAE concept), and non-arbitrability. UAE courts have progressively narrowed the public policy exception in recent years.

What is the difference between DIAC and DIFC arbitration?

DIAC (Dubai International Arbitration Centre) is the primary Dubai-seated institutional arbitration body, administering proceedings under the DIAC Arbitration Rules 2022 with Dubai as the seat. DIFC arbitration refers to proceedings with the DIFC (Dubai International Financial Centre) as the seat, governed by DIFC Arbitration Law (DIFC Law 1/2008 amended 2021). The DIFC seat is administered by the DIFC Arbitration Institute (DAI) and is preferred by parties seeking direct DIFC Courts enforcement of arbitral awards without a separate ratification step required in UAE mainland courts. ICC cases frequently use the DIFC seat.

Is mediation mandatory before litigation in UAE courts?

Yes, for many commercial disputes. Federal Decree-Law 40/2023 on Mediation in Civil and Commercial Disputes requires claimants to attempt mediation at an MOJ Mediation Center before filing suit in specified civil and commercial categories at UAE federal courts. Mediation must be completed within 30 days (extendable by agreement). If mediation fails, claimants receive a certificate enabling court filing. Dubai Courts maintain a parallel mandatory mediation system through the Dubai Centre for Amicable Settlement of Disputes (CASES). Abu Dhabi Judicial Department (ADJD) has equivalent pre-litigation mediation requirements.

How much does it cost to set up an ADR practice in UAE?

Establishing a UAE ADR and arbitration advisory practice costs AED 500,000–3,000,000 depending on scope. A standalone advisory and case management practice costs at the lower end: DIFC or mainland office (AED 50,000–200,000/year), DIAC arbitrator accreditation, MOJ mediation center registration, DED or DIFC legal consultancy license (AED 10,000–30,000), and professional indemnity insurance (AED 20,000–100,000). Operating a full ADR institution with administered arbitration requires substantially higher capital for regulatory approvals, case management technology infrastructure, and permanent secretariat staffing.
