Our International Arbitration Group comprises of barristers and affiliated lawyers from around the world. Our members are some of the foremost practitioners in the field.  The Group's members have participated, both as counsel and as arbitrators, in commercial arbitrations under the rules of every major arbitral institution, as well as in ad hoc (non-institutional) and investment treaty claims, and before the Court of Arbitration for Sport.

On the commercial side, 4-5 practitioners have acted for claimants and respondents at every stage of their disputes, from advice drafting arbitration clauses to bringing or defending challenges or enforcement proceedings in connection with arbitral awards. Our investment treaty arbitration experience is similarly extensive; our members act for both investors and host states. Members with experience as neutrals likewise have been appointed, and served as Chair, in virtually every variety of international dispute.

Our collective arbitration experience, unsurprisingly, covers many sectors: oil and gas, non-petroleum extractive industries, renewables, agriculture, intellectual property, financial services, insurance and reinsurance, shipping, corporate transactions, construction projects, and e-commerce.

Our depth of expertise combined with our flexible and attractive fee structure enables us to supply our clients' legal needs effectively, efficiently, and affordably. 4-5 Gray's Inn Square also offers a fixed price service tailored to disputes requiring a quick resolution to be dealt with on paper or by way of a hearing.
