Professional Negligence

Businesses and individuals rely more and more on the advice they receive from professional advisors. However, in times of growth, views are often expressed or advice given which is over-optimistic or even wrong. While conditions are good, such advice is rarely challenged. In the current economic environment, with businesses under pressure to root out non-performing assets, it is hardly surprising that professional advice has come under the microscope and bad advice, breaches of duty and even fraud has been exposed. The problems caused by claims arising from such advice range from the amount of time involved in bringing a claim to the prospect of unwanted publicity for the various parties involved.

Why we are different

The handling of claims against other professionals demands a team which combines experience and intellect.  A team such as ours at Mishcon can assess each case on its own merits and respond in an aggressive or measured manner as appropriate. We have a particular eye on a longer-term relationship that our clients have with their other advisers and endeavour to resolve claims using alternative dispute resolution processes where appropriate.

We act for businesses, investors, property developers, banks and other financial institutions, family offices and private individuals in claims against solicitors, accountants, surveyors, architects, financial advisers and other professionals.

Our practitioners are extremely experienced, having worked through previous UK recessions, and many of our claims settle without litigation. Where this is not possible, we also have extensive trial experience. In cases that are not capable of settlement, we also offer our clients MISHCON PROTECT®, our unique package of products expertly designed to assist clients in obtaining funding for their own fees in a litigation matter and to provide protection against the client’s risk of having to pay their opponent’s costs and their own disbursements should their action be unsuccessful.
