Knowledge Pack — DIAC Arbitration

• Whether to use DIAC vs other institutions (DIFC-LCIA [now DIAC], ICC, LCIA, ADGM)
• Drafting DIAC arbitration clauses
• Understanding procedural milestones under DIAC Rules 2022
• Seat selection and its legal consequences
• Enforcement of DIAC awards
• Emergency arbitrator applications
• Multi-party and multi-contract proceedings

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 The former DIFC-LCIA Rules were effectively superseded.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

	DIFC seat	Onshore Dubai seat
Supervisory court	DIFC Court of Appeal	Dubai Court of Appeal (onshore)
Language	English	Arabic
Court tradition	Common-law	Civil-law (Emirati)
Setting-aside ground standard	English / common-law precedent	UAE Federal Arbitration Law
Enforcement of foreign awards	New York Convention via DIFC Courts	New York Convention via UAE federal courts
Speed of court proceedings	Generally faster	Variable

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

Stage	Rule	Timeframe
Request for Arbitration filed	Art. 4	Day 0
Response to Request	Art. 5	30 days from receipt
Appointment of Arbitral Tribunal	Arts. 14–18	30–45 days from Response
Tribunal's first procedural order	Art. 24	Promptly after constitution

Statement of Defence	Art. 26	Per timetable (typically 4–6 weeks after Claim)
Reply + Rejoinder (if permitted)	Art. 26	Per timetable
Evidentiary hearing	Art. 29	After pleadings; typically 6–12 months from filing
Final award	Art. 42	6 months from close of proceedings; extendable by agreement or DIAC

Expedited procedure

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)

Factor	DIAC	ICC	LCIA	ADGM

Supervision	DIFC or onshore Dubai	ICC Court (Paris)	LCIA Court (London)	ADGM Courts
Administration fees	Lower	Higher	Medium	Lower
Speed	Medium	Slower (scrutiny process)	Medium	Medium
Enforceability	NY Convention	NY Convention	NY Convention	NY Convention

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
