Sarnjit Lal leads the firm’s U.K White-Collar Crime Investigations and Enforcement group. She has more than 20 years of experience in major criminal investigations and proceedings.

Sarnjit has deep experience in handling white-collar crime investigations and internal investigations faced by corporations and individuals. Sarnjit handles complex fraud and serious criminal cases investigated by the Serious Fraud Office (SFO), Financial Conduct Authority (FCA), HMRC Revenue & Customs, National Crime Agency (NCA), Competition & Market Authority (CMA) and other prosecuting and disciplinary bodies. Sarnjit is often involved in multi-jurisdictional investigations involving international law enforcement agencies.

Sarnjit represents clients from a very early stage, usually prior to the commencement of an investigation, and is renowned for her success in resolving matters at an early stage without the need for criminal proceedings. Where required, Sarnjit is well experienced in representing clients throughout the entire criminal litigation process, from internal investigation and criminal proceedings to post-trial matters including confiscation.

Sarnjit’s matters are often high-profile and high-stake. Recognised for her discreet yet robust approach, and excellent crisis management skills, Sarnjit is sought after by both corporations and high-net-worth individuals to advise on complex white-collar crime and criminal investigations.

Named a leading lawyer by Chambers U.K. and the Legal 500 U.K., Sarnjit is described as “astute” and valued for her “calm manner in a crisis.” Clients have also said she is excellent in “keeping high-profile cases out of the public limelight” and “leaves no stone unturned.”


Prior to joining Armstrong Teasdale, Sarnjit was Partner and Head of department at a specialist criminal London law firm serving as one of the leading partners for white-collar crime, fraud and individual crisis management.
