He applies this insight to advise clients facing the most serious legal risks, particularly in the areas of internal investigations, criminal defence, and private prosecutions.

He regularly acts for corporations, executives, and professionals facing regulatory scrutiny or criminal allegations, offering clear guidance in high-stakes and high-pressure situations.

What his clients say
I had the pleasure of working with Jack Murphy and Elisha Kaur, and I was thoroughly impressed by their service. Their communication was consistently clear, timely, and professional, which made the entire process feel well-managed and reassuring. They both demonstrated a strong command of the law and were quick to identify the key issues at hand. What stood out most was their initiative and strategic thinking – they were always one step ahead, ensuring no detail was overlooked. Jack and Elisha are an excellent legal team, and I would not hesitate to recommend them.
Two of my personal watches which were held on consignment were seized because they were in the possession of a dealer arrested for suspected money laundering. When I tried to recover the watches myself, I was unsuccessful, likely due to legal and bureaucratic hurdles. After instructing Jack Murphy, he quickly navigated the legal system, provided proof of ownership, and ensured compliance with authorities. Within two weeks, my watches were returned. His expertise and efficiency led to a successful outcome, and was highly satisfied with his service. This highlights the importance of legal representation in asset recovery cases.
I can't thank JMW Solicitors enough, especially Jack Murphy. For approximately 18 months Jack and his team and have assisted me with a complex matter and throughout this time have provided me with outstanding legal expertise. In addition, each time conversing with Jack he was extremely personable and approachable and speaking with him put me at ease on each occasion. I couldn't have asked for a better result and I would recommend anyone to use JMW Solicitors.
I can't thank JMW Solicitors enough, especially Andrew Gilligan Jack and Catherine Gaynor. From the outset they were there for me, for both my legal and welfare needs and supported me throughout my works disciplinary against me.
