About
Provided by Herbert Smith Freehills
We advise clients on arbitrations under a broad spectrum of civil and common laws. We are experienced in arbitrating under the rules of all major arbitration institutions, as well as having conducted numerous ad hoc arbitrations. Our genuine sector knowledge, commercial awareness and regional sensitivity are unrivalled. We advise clients and conduct arbitrations in a number of languages. Once you have an arbitral award, we can help you to enforce it around the world.
Our long standing experience of acting in investor-state and state-to-state arbitrations and in-depth knowledge of the nuances of these specialist areas means we can help you to best meet your objectives. We provide advice on the best possible investment and treaty protection.
Conducting our own advocacy means our skilled advocates play a critical role in the strategy of the case from the outset. It also minimises the cost and time involved for our clients in instructing external counsel. Members of the arbitration group regularly sit as arbitrators and this valuable insight into the arbitral process from a different perspective helps us to identify winning strategies.
Whether you are a financial institution, a multinational corporation, a government or a state-owned entity, we combine in-depth legal and sector knowledge with a proven track record of successfully acting in complex disputes, working alongside local counsel where appropriate.
