He is well known for his work in the Professional Liability field, where he handles claims and insurance coverage disputes. He regularly advises in claims concerning accountants and auditors, real estate professionals, trustees (in particular in offshore jurisdictions), asset managers, IT professionals and lawyers. Recent work includes cases involving failure to detect fraud, mortgage fraud, valuations of property and other assets in falling/unstable markets, claims arising from allegedly negligent audits, tax planning and tax mitigation schemes as well as claims against Insolvency Practitioners. Jim has also spent significant time recently advising professionals as to their duties to produce documents and information to the SFO, FSA, HMRC and to Insolvency Practitioners. In recent years he has often been instructed by excess layer markets as claims develop to advise on policy issues (often aggregation) and strategy. He is frequently asked to protect their interests in settlement discussions and at mediations. Jim also advises in relation to Financial Institutions and D&O claims in a range of disputes, including the international oil sector, offshore investment companies and funds and other businesses. He has also recently spent significant time advising the underwriters of Insolvency Practitioners' Bonds as to the extent of their obligations.
