Derek Holwill specialises in professional negligence and clinical negligence claims. He is listed by both the Legal 500 and by Chambers UK in the top rank of juniors working in the professional negligence field. His work also includes advising on coverage issues and general insurance policy matters.
Derek deals with a very wide variety of claims involving both solicitors and barristers. Cases concluded in the course of the last year include Rangestage Ltd v Mark Gilbert Morse, a claim against solicitors relating to the drafting of Sale & Purchase Agreement, where the action was successfully struck out; Patel v Kennard Wells and Chan v Kennard Wells, both claims against solicitors arising out of the alleged mishandling of the security for privately arranged loans; West One v Griffiths Ing, a claim against solicitors for an alleged breach of undertaking, involving both construction, causation and trust issues and Mulcahy v Castles (CA) concerning the alleged failure properly to instruct Counsel. Derek also acted for the solicitors in Davisons v Nationwide  PNLR 12 (CA) an important case involving a breach of trust claim by a mortgage lender against a solicitor, where the solicitor was relieved of liability under the Trustee Act 1925 s.61 because he had acted honestly and reasonably, and the loss had been caused by the fraud of an unconnected third party.
Current cases include a multi-million claim against solicitors alleged to have mishandled commercial litigation relating to the misuse of confidential information, and an associated claim against the expert witnesses who advised in relation to that litigation; a substantial claim relating to the drafting of an agreement relating to development land; a claim against a KC and his instructing solicitors arising out of the drafting of a settlement agreement in a clinical negligence claim; a series of claims against solicitors arising out the sale of investment properties “off-plan”, where sales were concluded at a marketing event arranged by the developers; and a claim against solicitors (and Counsel) where is alleged that there was a negligent failure to appreciate that an insurance claim was doomed to fail. Derek also continues to be instructed in managed litigation in a claim against conveyancing solicitors involving 50+ conveyancing transactions, where it is alleged the conveyancer concerned was guilty of serial negligence or dishonesty allowing various permutations of mortgage frauds to be perpetrated. Derek also continues to act in a number of mortgage lender claims (both for claimants and for defendants), in a wide variety of claims for and against conveyancers and in claims against in respect of allegedly tax advice.
Derek regularly advises on claims for and against valuers, both in the context of contribution claims made by solicitors who have been sued by mortgage lenders; and in their own right. Cases in the course of this year include DB Bank v Colleys where Derek was acting for valuers in a claim relating to a series of valuations of residential properties. He continues to act for mortgage lenders in a substantial claim against valuers involving multiple valuations (and possibly fraud) and in the case of Savills v Dorchester Group, a claim involving allegedly negligent expert advice given by valuation experts in the course of commercial litigation. Other recent cases include Excel v Alder King, a claim by a tertiary lender against valuers, raising interesting issues on contributory fault and quantification of loss.
Derek regularly advises on claims for and against accountants. Cases in the course of the last year include two separate actions against accountants who had failed, when producing an accountant’s report for the purposes of the Solicitors’ Accounts Rules, to pick up evidence of fraudulent misappropriations by a solicitor. Derek has also been involved in recent decisions on limitation issues in claims against accountants, including Law Society v Sephton (HL).
Derek deals regularly with claims involving financial advisers and is currently representing IFAs in a number of claims where the it is alleged that investment recommendations did not match the client’s risk profile and where it is said there were related breaches of the COBS and of FSMA.
Derek has considerable experience of claims against insurance brokers. Claims in the course of the last year involve a broker who allegedly failed to advise properly a client in relation to conditions precedent in a Business Interruption policy – a claim giving rise to both factual and causation issues.
Derek frequently advises on coverage issues, predominantly for insurers, but also for the insured. He regularly advises on a wide range of construction issues including about the inter-relationship between contractual wordings and any applicable “minimum terms” (most commonly in the context of solicitors’ PI policies) and about the applicability of exclusions – most commonly, the dishonesty exclusion in solicitors’ and surveyors’ PI policies (something usually involving conducting “indemnity conferences” with the indemnified on behalf of the insurer). He has conducted numerous arbitrations on coverage issues, both between insurer and insured, and between insurers. He has from time to time been jointly instructed to act as a quasi- arbitrator, and provide an Opinion which the parties have agreed should be determinative of their coverage dispute.
