Alessia de Quincey

Counsel

Alessia is a Solicitor Advocate based in our London office. She advises clients on a range of contentious issues. Her broad legal practice focuses on high stakes commercial litigation and arbitration as well as internal and regulatory investigations. She has been involved in a number of high-profile cases, acting for both individuals and corporates.

Alessia has received consistent praise and recognition from the legal directories. She is recognised as a key lawyer in the UK Legal 500 2025 for Regulatory Investigations and Corporate Crime (advice to corporates) and Financial Services: Contentious, where she is described as “highly intelligent”, and part of a team that is “Always available. Always listening to the client. Always quick to respond. Sound advice and, especially, advice that takes into account how the client sees the situation”. She is also noted for being “very skilled and definitely one to watch”.

Alessia was also recommended by the UK Legal 500 2024 for Regulatory Investigations and Corporate Crime (advice to corporates), White Collar Crime (advice to individuals) and Commercial Litigation: premium, where clients described her as “a brilliant legal professional and a rising star in her field” who is “razor sharp, efficient and effective in everything she does”, and also praised for being “a very steady pair of hands, with a masterful grasp of the detail of the matters she works on.” Alessia has previously been singled out as a “standout associate” who has impressed clients with her “handling of the detail”.

Alessia regularly appears as a Solicitor Advocate in the Chancery Division of the High Court on a pro bono basis in support of the Chancery Litigant in Person Support Scheme (CLiPS). She is consistently recognised by the Bar Association and has been awarded the Pro Bono Champion Award for the third year running since 2023.
