Karl S. Moussalli

Karl Moussalli is a dual-qualified English and French lawyer with a broad commercial litigation, international arbitration, and investigations practice. He focuses on complex, high-stakes multijurisdictional disputes involving fraud, corruption, and asset misappropriation and in designing and implementing strategies to enforce judgments and arbitral awards against well-connected debtors in challenging jurisdictions.

Clients describe him as "one of a kind" and "really on top of his game," with "excellent legal knowledge and strategic thinking." Drawing on both civil and common law systems, he "knows and uses his arsenal in all countries, and spots opportunities, risks and effective ways forward where most can't." The Legal 500 ranks him as a Next Generation Partner for Civil Fraud.

Karl's recent caseload includes: obtaining and enforcing more than US$3 billion in arbitral awards and judgments for a client whose investment was expropriated through fraud, bribery, and corruption; US$350 million civil fraud claims for an oil trader against former directors; multijurisdictional defense of ultra-high-net-worth individuals (UHNWIs) facing parallel criminal and civil claims tied to an alleged billion‑dollar fraud; disputes linked to the allegedly corrupt sale of a Nigerian oil block triggering actions across six jurisdictions; enforcement of a c. US$80 million ICC award against a politically connected Middle Eastern commodities group, combining award enforcement and investment treaty proceedings; defense of a global trading house against a c. US$50 million extortion scheme spanning African jurisdictions; advice to financial institutions on attachment risks in sovereign financing transactions; and high-value arbitration and litigation (including fraud and contractual claims) against sellers of a Middle Eastern business arising from concealed liabilities.
