“Kate Vaughan-Neil is a highly sought-after barrister with a particular focus on professional negligence” (as demonstrated by her Legal 500 ranking within Tier 4), insurance and commercial litigation; appearing in substantial high court and arbitration matters as both sole and junior counsel.

Her professional negligence expertise covers most of the main professions with particular emphasis on those involving solicitors, architects and engineers, but also surveyors, barristers and financial advisers. Chambers & Partners has previously described Kate as “very considered; immediately seeing the potential counter-arguments and how they could affect the strategy”.

As regards her wider commercial experience, Kate has been engaged by two major retail banks in respect of two separate FCA Reviews, namely the review into mis-sold interest rate hedging products, where she advised on numerous consequential loss claims; and the review into one bank’s business support unit, where she was part of a panel determining appeals brought by customers against the bank’s determination of its claims under the review. She has also has experience of fraud claims, including acting for an Azerbaijani travel agency in a claim (settled just before trial) arising out of a failure to provide aircraft under a charter agreement.

Kate is also qualified to undertake Public Access work.

Kate has a broad and well-established professional negligence practice, which covers most of the main professions, with particular emphasis on those involving solicitors, architects and engineers, but also including surveyors, barristers and financial advisers.
