Dispute Resolution analysis: Mr Justice Fancourt, Vice-Chancellor of the County Palatine of Lancaster, sitting in the Business and Property Courts in Leeds, held that Reynolds Porter Chamberlain LLP (RPC) owed a duty of care to its client, Deborah Forster (‘the Claimant’). Specifically, it had a duty to keep her informed of the ‘staggeringly high level of costs’ that were accruing throughout the retainer, with the commensurate risk of a shortfall in costs recovery that would erode any judgment she obtained. By the time the case settled, the costs had reached £5m. The Claimant had agreed to pay these costs under the terms of a conditional fee agreement (CFA), however, she argued that RPC had been negligent in failing to keep her informed of the costs of litigation, and in failing to advise her on the risks of incurring high costs. This case is significant for practitioners in the field of commercial litigation, as it clarifies the duties that solicitors owe to their clients under a CFA. The court’s decision in this case makes it clear that solicitors must keep their clients informed of the costs of litigation, and that they must advise their clients on the risks of incurring high costs, even if the client has agreed to pay those costs on a ‘no win, no fee’ basis. As a separate point, the case highlights the importance of choosing the right expert in commercial litigation. The court’s decision in this case suggests that solicitors should advise their clients to use experts who are likely to be cost-effective, in addition to providing reliable and accurate evidence.
