Sarnjit Lal has more than 20 years’ experience in fraud and major criminal cases covering all stages of criminal law and cross-border disputes. She leads the firm’s U.K. White-Collar Crime and Investigations Department. Her matters are often high-profile and high-stakes, and she has extensive experience in handling both internal investigations and those brought by the Financial Conduct Authority (FCA), Serious Fraud Office (SFO), Revenue & Customs (HMRC) and other prosecuting authorities.

Sarnjit is recognized for her discreet yet robust approach, and excellent crisis management skills. She is regularly instructed by both companies and individuals to advise on complex fraud and white-collar crime cases and advises her clients throughout the entire criminal procedure from the beginning of an investigation, during the police investigative stage and including any criminal proceedings.

Recognized by Chambers U.K. and the Legal 500 U.K., Sarnjit is described as “astute” and valued for her “calm manner in a crisis. A highly efficient lawyer who passionately pursues the best interests of her clients.” Clients have also said she is excellent in “keeping high-profile cases out of the public limelight and leaves no stone unturned. I find her judgement always sound and dependable.”
