What Asserson Law does
Asserson Law is a London-headquartered, full-service international law firm founded in 2005, operating as a partnership regulated by the Solicitors Regulation Authority (registration number 549779). The firm was originally established as an experiment in providing English legal services from an offshore Tel Aviv location, and has since expanded to become a Legal 500-ranked practice with offices in London, Tel Aviv (its largest office in the Azrieli Centre business district), Manchester, and New York (trading as Asserson Hiller PC). It employs approximately 15 partners and over 50 lawyers, with senior practitioners drawn from top-tier City and international firms such as Eversheds, Aubrey David, and Brabners.
The firm delivers legal services under both English and US law across 12 practice areas, organized into Dispute Resolution, Business Law (Corporate, Corporate Finance, Commercial/IP/IT/Privacy, Employment, Care Homes), Real Estate, Banking & Finance, Insolvency & Restructuring, Planning, and a dedicated US practice. Its core clientele includes major banks (HSBC, JPMorgan Chase, Credit Suisse), sovereign states (UK Government, Ministry of Defence), large corporations (Vale SA, Football Association, Breyer Group), and high-net-worth individuals engaged in complex multi-jurisdictional litigation, international arbitration, group actions, and high-value corporate transactions. Notable mandates include the $2 billion Vale SA v Steinmetz fraud claim, the £60 million-plus Human Rights Act recovery for solar energy companies, the £21 million UCL student group settlement, and the principal Madoff UK trial defense.
Revenue is generated through traditional professional services fees — hourly billing, fixed fees for defined matters, and contingency/success fees for litigation — with terms negotiated per engagement. The firm distributes services through direct partner-led client engagement, supported by directory rankings (Legal 500, Chambers, Who's Who Legal) and content marketing via its website. Recent strategic motion centres on Manchester office expansion under new senior partner Michael Clavell-Bate, with continued 2026 hiring and practice-wide growth planned.
