Investigations and White Collar Defence for Corporates and Senior Executives
The specialist corporate investigations solicitors at Edmonds Marshal McMahon advise corporates, senior executives and high-net-worth individuals on complex white-collar crime, regulatory enforcement and internal and corporate investigations.
Our team combines experience from the Serious Fraud Office (SFO), Financial Conduct Authority (FCA), Crown Prosecution Service (CPS) and Medicines and Healthcare Products Regulatory Agency (MHRA) with specialist advocacy, investigation and digital asset expertise.
Navigating an increasingly complex enforcement landscape
The reputational, regulatory and criminal liability landscape for corporates and senior executives has changed significantly over the last 20 years. The continued relaxation of the rules governing corporate attribution has made the prospect of internal and external investigations and regulatory enforcement actions increasingly likely.
The changing enforcement landscape means no two investigations are ever the same. Each matter requires a tailored, adaptable and strategic approach, led by genuine experts who understand the legal, commercial and reputational pressures involved.
Meet our corporate investigations team
Our corporate investigations and white collar defence team is led by Satnam Tumani, a member of the Legal 500 Hall of Fame for white collar crime and investigations. Satnam is supported by a diverse, multidisciplinary team with experience across criminal law, corporate investigations, regulatory enforcement, financial crime and digital assets.
Along with former investigators from the SFO, FCA, CPS and MHRA, we have a dedicated in-house team with expertise in gathering intelligence and evidence, conducting money-flow reviews, assisting with document reviews, supporting interviews and carrying out evidential assessments.
We also have in-house specialist criminal law barristers who provide advocacy and advice on particularly complex areas of criminal law. In addition, we are one of the few practices with genuine and dedicated crypto and digital assets expertise, advising on cases involving cryptocurrencies, non-fungible tokens, exchanges and related investigations.
