  • Profile
  • Experience
  • Key contacts
We have represented clients in arbitration proceedings under the rules of all the major institutions and trade associations, such as LCIA, ICC, CIETAC, SCIA, SIAC, HKIAC, DIFC-LCIA, LMAA, SCMA, FOFSA, GAFTA, UNCITRAL and ICSID.

Our expertise is global, led from our offices in London, Paris, Dubai, Hong Kong and Singapore, with support from our other offices.

We have particular experience of international arbitrations relating to emerging markets, especially Africa, India and the CIS.   We are frequently instructed in arbitration matters by clients and law firms in those regions and in other jurisdictions.

We can help you with disputes across a wide range of sectors, including aviation, energy, international trade, commodities, shipping, and financial services.

Our expertise is reflected in the wide variety of clients for whom we act including global airlines, ship owners, energy companies, insurers, traders and entrepreneurs and sovereign governments.

We have in-depth knowledge of arbitral law and procedure – but more importantly we never lose sight of the commercial realities, pressures and priorities that our clients have to face every day.

Our expertise is reflected in the regular arbitral appointments received by our dedicated international arbitration partners.  Three partners have authored books on arbitration topics and our team members regularly speak at international conferences. 

In the past decade, we have handled some of the most high-profile proceedings to enforce, or resist the enforcement of, arbitral awards before the English, Hong Kong and Singapore courts.

Our team is a natural first choice to instruct on such matters. 

Stephenson Harwood "performs excellently and its experienced practitioners are able to handle the most difficult and complex disputes efficiently."
