International arbitration is won or lost long before the hearing — in the drafting. The single most consequential decision in any arbitration clause is not the institution or the rules; it is the seat.
The seat is the arbitration's legal home
The seat of an arbitration is a juridical concept, not a geographic one. It is entirely possible — and common — for hearings to take place in one city while the arbitration is legally seated in another. The seat is the country whose law governs the arbitration as a proceeding, and it fixes four things that decide the fate of a dispute:
- the lex arbitri — the curial law that governs how the arbitration is conducted, the tribunal's powers, and the validity of the process;
- the supervisory (curial) court — the only court that may support the arbitration and, later, hear a challenge to the award;
- the grounds and the forum on which an award can be set aside or annulled; and
- the award's nationality for the purposes of cross-border enforcement under the New York Convention.
Parties routinely conflate the seat with the venue, or leave it unstated, or bury it in a boilerplate clause copied from an unrelated contract. The cost surfaces years later: a challenge heard by a court the parties never intended, an award of a nationality that complicates enforcement, or curial law that permits interventions the parties assumed were closed off. A defective seat cannot be repaired after the dispute has crystallised.
Choose the seat deliberately, or a court you never chose will choose the outcome for you.
Choosing a seat — the options open to UAE parties
The UAE is unusual: within a single federation it offers three distinct legal environments in which to seat an arbitration, each with its own curial law and its own supervisory court.
Onshore UAE (Dubai, Abu Dhabi)
An onshore seat brings the arbitration under the Federal Arbitration Law No. 6 of 2018, a modern statute broadly aligned with the UNCITRAL Model Law. The supervisory courts are the onshore Courts of First Instance / Cassation of the relevant Emirate, applying UAE civil law. This is the natural home for domestic contracts performed onshore and for enforcement against onshore assets.
The DIFC as a common-law seat
The Dubai International Financial Centre is a common-law jurisdiction with its own arbitration law and, critically, its own curial court — the DIFC Courts — staffed by internationally recruited judges. Since the DIAC Arbitration Rules 2022, where the parties have not agreed a seat the DIFC is the default seat (Article 20.1), with the tribunal retaining power to fix the seat definitively. That default matters: silence now routes supervision to a common-law court rather than the onshore courts.
The ADGM as a common-law seat
Abu Dhabi Global Market offers an equivalent common-law option under the ADGM Arbitration Regulations 2015, again Model-Law based, with the ADGM Courts as the curial court. For parties who want a common-law lex arbitri with an Abu Dhabi footprint, the ADGM is the counterpart to the DIFC.
Foreign seats
London, Paris, Singapore and Geneva remain the established international seats, each with deep supervisory jurisprudence and a court culture of minimal, predictable intervention. A foreign seat can be the right answer where neutrality between the parties is paramount — but it should be chosen for its curial law and its courts, not for its convention-centre reputation.
Institutional versus ad hoc, and the consolidation of Dubai
Arbitration may be institutional — administered by a body under its own rules — or ad hoc, typically under the UNCITRAL Arbitration Rules with the parties and tribunal running the process themselves. Institutional administration buys scrutiny, default machinery and a fee schedule; ad hoc buys flexibility and lower cost, at the price of self-management.
In Dubai the landscape was reshaped by Dubai Decree No. 34 of 2021, which consolidated the Emirate's arbitration institutions into the Dubai International Arbitration Centre (DIAC) and abolished the DIFC-LCIA. Clauses that still name the DIFC-LCIA must be read against that consolidation, and legacy references require careful handling. Alongside DIAC and its 2022 Rules, the principal international choices remain the ICC, the LCIA, and the UNCITRAL Rules for ad hoc proceedings.
The process, end to end
A well-run arbitration follows a disciplined arc:
- The agreement. The clause must be self-consistent — seat, rules, number of arbitrators, language and governing law all pulling the same way. Pathological clauses that name a non-existent institution, or contradict themselves on seat and rules, are the most common self-inflicted wound.
- Commencement by request or notice of arbitration, fixing the date proceedings begin.
- Constitution of the tribunal — one or three arbitrators, appointed by the parties and/or the institution, with disclosure of independence and impartiality.
- Procedure and evidence — pleadings, document production on a proportionate basis, and factual and expert evidence, ordinarily framed by a procedural order and the tribunal's broad discretion over the conduct of the reference.
- Hearing, deliberation and award — a reasoned, binding award that disposes of the dispute and, once issued, is final subject only to the narrow challenge grounds below.
Interim and emergency relief
Urgency does not have to wait for a tribunal. Modern rules, including the DIAC 2022 Rules, provide for an emergency arbitrator to grant urgent relief before the tribunal is constituted. Once constituted, the tribunal itself may order interim measures — security, preservation of assets or evidence, or measures to hold the position pending the award. These sit alongside court-ordered support: the supervisory court of the seat, and courts where assets are located, can grant protective measures in aid of the arbitration without trespassing on the merits.
Challenging an award — a narrow, closed door
An award is not a first-instance judgment open to appeal. Under Article 53 of Federal Law No. 6 of 2018, the grounds to set aside are a closed and exhaustive list, mirroring Article V of the New York Convention: no valid arbitration agreement or incapacity; denial of a party's right to present its case or defective due process; improper constitution of the tribunal or procedural irregularity affecting the award; and the tribunal exceeding the scope of what was submitted. The court may also act of its own motion where the subject matter is not arbitrable or the award contravenes UAE public order (Article 53(2)). The challenge must be brought within a strict 30-day window.
Crucially, this is not a merits review. The court does not re-hear the dispute or second-guess the tribunal's findings of fact or law. Recent UAE appellate authority has reinforced the exclusivity of the Article 53 grounds and their narrow construction. The public-policy ground deserves particular emphasis: it has been progressively narrowed and confined to genuine breaches of the fundamental order of the State. "Public-policy incompatibility" is not a back door for re-opening the merits — an argument that the tribunal simply got it wrong is not a public-policy argument, and courts increasingly treat it as such.
Recognition and enforcement
An award is only as valuable as its enforceability. The New York Convention 1958 — to which the UAE acceded by Federal Decree No. 43 of 2006, without reservation — obliges the courts of over 170 states to recognise and enforce foreign awards subject only to the narrow Article V defences. Onshore, enforcement runs through the execution judge under the Civil Procedure Code (Federal Decree-Law No. 42 of 2022), with the enforcement conditions and the treatment of foreign awards addressed at Articles 222 and 223, and Article 225 confirming that the UAE's treaty obligations — including the Convention — prevail over the domestic provisions.
The DIFC and ADGM add a further route: as common-law courts that recognise awards and, by memoranda of understanding with the onshore courts, act as a conduit for onward enforcement against onshore assets. One live obstacle stands apart from all of this — state immunity. Enforcing an award against a sovereign or state entity raises immunity from execution over protected assets, a distinct hurdle that must be planned for at the contracting stage, not discovered at enforcement.
Investment treaty arbitration
Distinct from commercial arbitration is investment treaty arbitration, where an investor sues a host State directly under a bilateral investment treaty or investment chapter, typically before an ICSID tribunal or under the UNCITRAL Rules. The consent is treaty-based rather than contractual, the respondent is a State, and the disciplines — fair and equitable treatment, protection against expropriation — are drawn from public international law. The enforcement architecture and the strategic calculus differ markedly from a commercial reference, and the two should never be conflated.
The engineer's edge
Construction, technology and systems disputes turn on how the machine actually behaves — delay analysis, defect causation, interacting systems, code and data. Having built and engineered such systems before practising law, I read the technical record the way the tribunal's experts do, and I can pressure-test a delay narrative or a defect theory from the inside. In disputes where the engineering is the case, that fluency is decisive.
