Background and current status

History

DIAC was established in 1994 as the Dubai Centre for Commercial Conciliation and Arbitration (DCCCA), renamed DIAC in 2004. Until 2021, the DIFC-LCIA Arbitration Centre operated alongside DIAC as a separate institution with its own rules (based on LCIA Rules adapted for the DIFC).

Dubai Decree 34/2021 consolidation

In September 2021, Dubai Decree 34/2021 dissolved the DIFC-LCIA Centre and transferred its caseload and operations to DIAC. The former DIFC-LCIA Rules were effectively superseded. All new filings from 2022 proceed under DIAC Arbitration Rules 2022.

DIAC Rules 2022

The DIAC Arbitration Rules 2022 came into force on 21 March 2022. They represent a significant modernization:

• Unified rules for domestic and international arbitrations
• UNCITRAL Model Law alignment
• Emergency arbitrator procedure
• Expedited procedure
• Multi-party and multi-contract consolidation rules
• Electronic filing and hearings supported
• Costs schedule updated

Seat of arbitration

Default and options

DIAC Rules 2022 default seat is Dubai. Parties may designate:

• DIFC as the juridical seat (DIFC Courts become supervisory court)
• Onshore Dubai (Dubai courts become supervisory court)
• Any other seat the parties agree

Why seat selection matters critically

Key trap: Parties often assume "DIAC" = "DIFC seat." It does not. The seat must be expressly stated. An unspecified seat in a DIAC clause defaults to onshore Dubai, which may not be what sophisticated parties intended.

Standard DIAC arbitration clause

Recommended clause (DIFC seat, English, three arbitrators)

Any dispute arising out of or in connection with this Agreement, including any question regarding its existence, validity or termination, shall be referred to and finally resolved by arbitration under the DIAC Arbitration Rules 2022, which Rules are deemed to be incorporated by reference into this clause. The seat of arbitration shall be the Dubai International Financial Centre (DIFC). The language of the arbitration shall be English. The number of arbitrators shall be three.

Variant (sole arbitrator, shorter disputes)

[...] The number of arbitrators shall be one.

Variant (DIAC expedited procedure)

[...] The Expedited Procedure under Article 33 of the DIAC Arbitration Rules 2022 shall apply.

What to include in the clause (checklist)

• Institution: DIAC (by full name and Rules year)
• Scope: "arising out of or in connection with" (broadest — covers tort and statutory claims)
• Seat (express)
• Language
• Number of arbitrators (1 or 3)
• Governing law of the contract (separate from governing law of the arbitration)
• Optional: specific qualifications for arbitrators (e.g., "qualified lawyer with MENA construction experience")

Procedural milestones under DIAC Rules 2022

Expedited procedure

Available (Art. 33) for claims ≤ AED 1M (approx.) or by agreement. Award due within 3 months from constitution. Sole arbitrator unless parties agree three.

---

Costs

Fees structure

DIAC fees comprise:

1. Registration fee (flat, paid on filing)
2. Administrative fees (scale with amount in dispute)
3. Arbitrator fees (determined by DIAC according to its schedule, based on amount in dispute and time)

DIAC publishes its current fee schedule on its website. For amounts in dispute of USD 1M–5M, expect combined DIAC fees in the range of USD 30,000–80,000 (illustrative; verify current schedule).

Costs allocation

The tribunal has discretion to allocate costs in the award. DIAC Rules 2022 follow the principle that costs follow the event, but the tribunal considers the parties' conduct throughout proceedings.

---

Emergency arbitrator

Availability

Available under DIAC Rules 2022 Art. 44, pre-constitution of the main tribunal.

Process

1. Application to DIAC Secretary General
2. Emergency arbitrator appointed within 1 business day of receipt
3. Emergency arbitrator fixes a timetable; decision within 14 days of appointment
4. Decision binding on parties and enforceable

Practical use

Used for: asset freezing, preserving status quo, preventing specific acts pending constitution of the main tribunal. Not a substitute for urgent court interim relief — consider both in parallel for high-stakes disputes.

---

Multi-party and multi-contract proceedings

Joinder (Art. 9)

A third party may be joined if all parties (including the third party) agree, or if the third party is bound by the arbitration clause and the tribunal deems joinder appropriate.

Consolidation (Art. 12)

DIAC may consolidate pending arbitrations where: the arbitrations arise under the same arbitration agreement, or where the claims are so closely connected that separate proceedings would be inefficient, and all parties agree or the same tribunal has been constituted.

---

Enforcement

Within the UAE

• DIAC awards are enforceable under UAE Federal Decree-Law 6/2018 on Arbitration (the UAE Arbitration Law, based on UNCITRAL Model Law)
• Application to competent UAE court (onshore or DIFC, depending on seat) to ratify the award
• Enforcement against assets within the UAE proceeds once the award is ratified

Outside the UAE — New York Convention

• UAE acceded to the 1958 New York Convention in 2006
• DIAC awards are enforceable in 170+ contracting states
• Grounds for refusal: incapacity, procedural irregularity, non-arbitrability, public policy
• DIFC Courts have been used as a "conduit jurisdiction" to enforce onshore awards internationally (DIFC-onshore enforcement bridge)

Key risk factors when using DIAC

1. Seat omission: failing to specify the seat defaults to onshore Dubai — may not match parties' intentions
2. Language ambiguity: if not specified, hearings may default to Arabic for onshore proceedings
3. Arbitrator nationality: for sensitive disputes, consider specifying that at least the presiding arbitrator is of a neutral nationality
4. Time-bar notices: under UAE arbitration law and DIAC Rules, time-bar provisions for raising procedural objections are strict
5. Emergency arbitrator vs court injunction: DIAC emergency arbitrator is useful but may not be as immediately enforceable as a court injunction
