DIAC — Dubai International Arbitration Centre

Overview

DIAC is Dubai's primary international arbitral institution, established in 1994 and substantially reformed by Dubai Decree 34/2021, which dissolved the DIFC-LCIA and merged all Dubai arbitrations under DIAC. The DIAC 2022 Rules brought DIAC to international best practice: emergency arbitrator, consolidation, joinder, expedited procedure, and multi-contract arbitrations. DIAC is supervised by a Board of Directors chaired by H.E. Omar Al Nuaimi (Chief Justice, Dubai Courts).

Seat Options

DIAC administers arbitrations with any seat, but default is Dubai (onshore UAE). DIAC also administers proceedings with DIFC seat (DIFC Arbitration Law No. 1/2008 applies — common-law curial framework). Parties may also designate ADGM seat with DIAC Rules (less common).

Fee Structure

DIAC fees under the 2022 Rules Appendix on Costs: (1) Registration fee AED 5,000; (2) Administrative fees — ad valorem, approximately 0.8–1.5% of amount in dispute on a declining scale; (3) Arbitrator fees — set by DIAC Court on an ad valorem basis within prescribed ranges. Indicative total (sole arbitrator, USD 5M dispute): AED 350,000–600,000 (USD 95,000–163,000). Use the DIAC Cost Calculator at diac.ae for specific estimates.

Best For

• Dubai real estate disputes (off-plan, JOP, master community)
• Dubai retail, hospitality, and entertainment sector disputes
• UAE-centric commercial contracts (DMCC, JAFZA, Dubai SMEs)
• Disputes where Arabic is the preferred language
• Enforcement against Dubai and UAE assets
• Construction disputes in Dubai (DIAC has strong construction arbitrator panel)

arbitrateAD — Abu Dhabi Arbitration Centre

Overview

arbitrateAD is Abu Dhabi's flagship arbitral institution — the reformed successor to ADCCAC, launched under new branding and new Rules in January 2024. The 2024 Rules reflect comprehensive modernisation: cybersecurity obligations (Art 29), expanded multi-party provisions, express conciliation-arbitration integration, and improved emergency arbitrator procedure. arbitrateAD is closely connected to Abu Dhabi's energy, construction, and government sectors.

Seat Options

Default seat: Abu Dhabi (onshore UAE). Parties increasingly use ADGM seat with arbitrateAD Rules — ADGM Courts (English-law, published judgments) provide a sophisticated curial framework for international parties. DIFC seat with arbitrateAD Rules is permissible but unusual. For government contracts, verify emirate-level capacity requirements for Abu Dhabi entities before specifying the seat.

Key Differentiator

arbitrateAD's higher expedited threshold (AED 3M vs DIAC's AED 1M) is practical for mid-tier Abu Dhabi disputes. Its cybersecurity protocol (Art 29) is the most comprehensive of any UAE institution — important for Abu Dhabi's data-intensive energy and technology sectors. The integrated conciliation procedure facilitates settlement without abandoning the arbitration framework.

Best For

• Abu Dhabi energy and oil & gas disputes (ADNOC, TAQA, ADNOC Group)
• Abu Dhabi government and quasi-government commercial contracts
• Abu Dhabi real estate (Aldar Properties, Abu Dhabi off-plan projects)
• Construction (infrastructure, water, utilities — Abu Dhabi market)
• Disputes requiring ADGM curial framework and ADGM-conduit enforcement
• Mid-tier disputes needing the higher AED 3M expedited threshold

SIAC — Singapore International Arbitration Centre

Overview

SIAC is Asia's leading arbitral institution and a top-five institution globally by caseload. For UAE parties, SIAC is the preferred neutral forum for cross-border transactions with Asian, European, and American counterparties. The SIAC Rules 2024 (7th edition) include innovations in third-party funding disclosure, joinder (Group of Companies doctrine codified), consolidation, and award transparency. SIAC's Court of Arbitration — 15+ senior practitioners from multiple jurisdictions — handles appointment and challenge decisions independently.

Seat Options for UAE Parties

Singapore seat (default): supervised by Singapore High Court (International Arbitration Act, Cap. 143A). Neutral, efficient, pro-enforcement. DIFC seat: DIFC Courts supervise, DIFC conduit enforcement in Dubai. ADGM seat: ADGM Courts supervise, ADGM-conduit enforcement in Abu Dhabi. The choice of seat is independent of the choice of SIAC as institution — SIAC Rules work with any seat.

Best For

• UAE-Asia cross-border transactions (India, Singapore, China, Korea)
• UAE-Europe and UAE-US transactions where counterparty insists on neutral seat
• Technology, commodities, and financial services disputes (international character)
• Large-value disputes (USD 10M+) where arbitrator quality is paramount
• Disputes requiring enforcement in multiple jurisdictions simultaneously
• Joint ventures with non-GCC international partners

ICC — International Court of Arbitration

Overview

The ICC International Court of Arbitration (Paris) is the world's most recognised arbitral institution with 900+ cases per year. The ICC Court exercises full award scrutiny (Art 34) — reviewing all awards before transmission to parties, ensuring quality and consistency. This makes ICC awards among the most difficult to challenge. ICC has an MENA regional office in Abu Dhabi (ICC MENA) and administers a significant volume of UAE-related cases, particularly large infrastructure, energy, and financial disputes.

Cost Reality for UAE Parties

ICC is significantly more expensive than DIAC or arbitrateAD. For a USD 10 million dispute with a 3-member tribunal, total ICC costs (administrative + arbitrator fees) can exceed USD 500,000–800,000. The USD 5,000 registration advance is the beginning — parties must make advance deposits for both administrative fees and arbitrator fees throughout the proceeding. For disputes under USD 10 million, DIAC/arbitrateAD typically offer equivalent quality at 30–50% lower cost. ICC is most cost-justified for disputes over USD 20 million.

Best For

• Large-value UAE disputes (USD 20M+) where counterparty requires ICC brand recognition
• UAE government infrastructure projects with international financing (World Bank, EBRD)
• UAE-Europe disputes where European counterparties insist on ICC
• Complex multi-party construction (ICC has longest track record in multi-party proceedings)
• Disputes requiring maximum challenge-resistance (ICC award scrutiny is strongest quality assurance)

EMAC — Emirates Maritime Arbitration Centre

Overview

The Emirates Maritime Arbitration Centre (EMAC) was established in 2016 by Dubai Government under the Dubai Maritime City Authority. EMAC specialises exclusively in maritime disputes — charter parties, bills of lading, cargo claims, collision, salvage, ship arrest, and maritime insurance. EMAC's arbitrator panel comprises maritime law specialists from UAE and internationally. EMAC Rules are maritime-specific, providing for expedited appointment, technical assessors, and ship arrest procedures. EMAC is the preferred forum for P&I Club disputes, ADNOC shipping disputes, and Jebel Ali/Khor Fakkan cargo disputes.

Best For

• Charter party disputes (time charter, voyage charter, bareboat)
• Cargo claims (damage, shortage, delay) — UAE ports (Jebel Ali, Khor Fakkan, Khalifa)
• Collision, salvage, and towage claims in UAE waters
• Ship arrest and release disputes
• Marine insurance disputes
• ADNOC tanker disputes

DIFC-LCIA Legacy & LCIA for UAE Parties

Overview

The DIFC-LCIA Arbitration Centre was the joint venture between LCIA (London) and DIFC established in 2008. Dubai Decree 34/2021 dissolved the DIFC-LCIA as of 11 September 2021, transferring all DIFC-LCIA cases to DIAC. New DIFC-LCIA clauses are no longer valid. Parties with legacy DIFC-LCIA clauses must now use DIAC or apply for a substitution agreement — see DIAC's transitional administration guidelines. For UAE parties seeking London arbitration, the LCIA (London) remains fully operational under LCIA Rules 2020 — appropriate for UAE-UK commercial disputes.

Action Required for Legacy Clauses

If your contract contains a DIFC-LCIA arbitration clause: (1) the clause is still valid and enforceable — parties are directed to DIAC per Decree 34; (2) for disputes already filed before March 2022, proceedings continue under DIAC administration with the same tribunal; (3) for future disputes under legacy DIFC-LCIA clauses, file with DIAC directly; (4) consider amending the clause by agreement to specify DIAC 2022 Rules explicitly in any contract amendment.

Ad Hoc Arbitration — UNCITRAL Rules

Overview

Ad hoc arbitration under UNCITRAL Rules 2013 means the parties administer the arbitration themselves without an institution. No registration fees, no administrative fees — only arbitrator fees (agreed directly with arbitrators) and venue costs. Ad hoc arbitration is suitable for: large-value sophisticated disputes where both parties have experienced legal teams; state-to-state arbitrations (UNCITRAL is the predominant ad hoc framework for investment treaty arbitrations); and where an institutional brand is contractually prohibited.

Risks of Ad Hoc for UAE Parties

Ad hoc arbitration requires both parties to cooperate on procedure — if a party is obstructive, there is no institution to intervene. UAE courts' support for ad hoc arbitrations under FDL 6/2018 exists (Art 18) but is slower than institutional support. For UAE commercial disputes, institutional arbitration (DIAC/arbitrateAD/SIAC) is almost always preferable to ad hoc — the cost savings are outweighed by the procedural risks. Reserve ad hoc for investment treaty claims and large inter-state or quasi-governmental disputes.

How to Choose an Institution

Decision Framework

The institution selection should be made at the contract drafting stage — not after a dispute arises. Once a dispute has arisen, parties rarely agree to change the forum, and a poorly drafted clause may force expensive litigation over the arbitration agreement itself. Apply the following framework:
