Seat vs venue
The seat is the juridical home of the arbitration. It determines which country's procedural law fills gaps in the parties' agreement, which courts supervise the arbitration and can order interim measures, which courts have exclusive jurisdiction to set aside the award, and how the award is characterised for enforcement under the New York Convention.
The venue, by contrast, is merely where hearings physically happen - and they can happen anywhere without changing the seat. Choosing London as the seat but holding a hearing elsewhere does not move the seat. Specify the seat expressly; do not leave it to be inferred from where people met.
Why the seat choice matters
Because the seat fixes the supervisory court and the setting-aside jurisdiction, it is one of the most consequential choices in the clause. Selection factors include the level of court intervention you find acceptable, the neutrality the seat is perceived to offer, the likely enforcement destinations, and practical cost and convenience.
London remains one of the most preferred arbitration seats in international surveys, alongside Singapore and Hong Kong - a reflection of supportive courts, a deep arbitration bar, and a well-understood legal framework.
Section 69 appeals on points of law
A distinctive feature of an English seat is section 69 of the Arbitration Act 1996, which allows a party to appeal an award to the English courts on a question of English law - a safeguard against legal error that most other major seats do not offer. It is, however, a default that is easily excluded.
Section 69 remains available by default for an English seat unless it is excluded, and many institutional rules exclude it automatically - including the ICC, LCIA, and SIAC Rules. Ad hoc and UNCITRAL Rules arbitrations are the common cases where it may remain available unless expressly waived, so check the chosen rules. Decide whether you value the safeguard or prefer finality, and draft accordingly - an express waiver, an institution whose rules exclude it, or a non-London seat.
Choosing an institution
The leading institutions differ in ways that matter commercially. The LCIA tends to bill arbitrators by hourly rate (often more economical for high-value disputes) and its rules exclude section 69 appeals. The ICC charges on an ad valorem basis tied to the amount in dispute and adds a distinctive scrutiny of draft awards by its Court before they are issued. SIAC is positioned as an Asia-Pacific hub with efficient expedited and emergency procedures, and HKIAC offers a mutual enforcement arrangement with mainland China that is valuable for China-connected disputes.
There is no best institution in the abstract - match it to the dispute: value, sector, likely enforcement destination, speed, and the parties' locations. And consider an expedited procedure or emergency arbitrator where speed may matter.
Drafting the seat and institution
State the seat (legal place) of arbitration as a specific city, name the institution and its current rules accurately, and set the number of arbitrators, the language, and the governing law of the contract. After August 2025, also state the law governing the arbitration agreement (see the arbitration-agreement law guide).
Use the institution's current model clause as the backbone and adapt only what you must. Getting the seat and the institution right at the drafting stage avoids expensive arguments about supervision and finality later.

Practical checklist
- Specify the seat as a city - it sets the procedural law and supervisory courts (not the venue).
- Do not confuse the seat with the venue; holding a hearing elsewhere does not move the seat.
- Decide whether you want section 69 appeals on points of English law - exclude them (or choose rules such as ICC, LCIA, or SIAC that exclude it) if you want finality; ad hoc and UNCITRAL arbitrations may leave it available unless waived.
- Match the institution to the dispute - LCIA, ICC, SIAC, or HKIAC each suit different needs.
- Name the institution and its current rules accurately, and set arbitrators, language, and seat.
- After August 2025, also state the law governing the arbitration agreement.
