Commercial / Chancery / Insolvency / Civil Fraud


Alexander has broad commercial and insolvency litigation experience covering a wide range of contractual, property and regulatory disputes.


His work includes an emphasis on civil fraud, white collar fraud, company, insolvency and regulatory matters, as well as complex commercial disputes generally.  Alexander regularly advises shareholders in joint venture disputes and acts in contentious matters involving trusts and involuntary liquidation. He has been the lead counsel in several long, complex, document heavy cases.


Alexander has conducted a considerable amount of complex contested trials and hearings and therefore is an experienced advocate and cross examiner in highly contentious and hard-fought cases in England and overseas.  Alexander has appeared numerous times in the highest courts and appellate courts of multiple jurisdictions.   Alexander has substantial experience of witness actions and in cross-examination and is well used to coping with the challenges presented by trials and major applications.


Alexander has not only practised at the Bar but also as a partner in an offshore law firm and as a Principal in a New York Law firm. Alexander is therefore used to taking a client friendly and pragmatic approach to cases with an emphasis on providing optimal solutions to client’s problems. Alexander’s international experience makes him particularly well suited to cases involved cross border issues and has much experience working with other legal teams in multiple jurisdictions on the same case.



Alexander practised at the English Bar for the first ten years of his career doing a variety of work including commercial, civil litigation, white collar fraud both criminal and civil as well as being appointed to the Attorney General Panel.


Alexander then went offshore where he was both a partner in a leading offshore firm and a Principal in a US New York based law firm.  Here he specialised in cross border disputes, financial services and insolvency.  These cases were invariably international in nature and involved ‘offshore’ elements to them.


Alexander returned to the Bar at NO.5 Chambers in 2019 and continues to do complex commercial and insolvency work both domestically and in international disputes.


He works with both leading law firms and Insolvency Practioners.
