Annabel Treadgold's practice focuses on multijurisdictional commercial litigation and arbitration, with an emphasis on complex civil fraud matters, and disputes arising out of the energy, resources, and construction sectors.

Prior to joining the Firm, Annabel primarily acted in disputes in the mining and energy industries, including construction arbitrations arising out of onshore and offshore oil and gas projects, and joint venture disputes arising out of mining operations.
