Practice overview

Jonathan has a broad trusts and commercial practice. Much of his time is spent on private, commercial or pension trust disputes and fraud disputes, both on and offshore. His litigation often takes him into other areas of law, and he has significant experience of cases with family, regulatory, insolvency and public law elements. He also has a significant advisory practice across this spectrum of work.

He very much enjoys the challenge of breaking down complex issues into simple, clear points and the advocacy involved in litigation, both oral and written.

Most recently, Jonathan appeared successfully on appeal before the Hong Kong Court of Final Appeal in the first case on Quistclose trusts before that Court, China Life Trustees Ltd (judgment 14 June 2024).

Jonathan was shortlisted for ‘Chancery Silk of the Year’ at the Chambers & Partners UK Bar Awards 2021 and at the Legal 500 Awards 2023.

He was appointed a Deputy High Court Judge in 2021.

He is consistently ranked in the directories for trusts (private and pension), matrimonial: trusts, offshore, civil fraud, traditional chancery and high-net-worth work (Chambers and Partners) and offshore, pensions and private client (The Legal 500).

Trusts, probate and estates: contentious

Jonathan is consistently ranked in Band 1 in Chambers & Partners for trusts work and separately as a star practitioner for trusts and divorce work. Jonathan was shortlisted for ‘Chancery Silk of the Year’ at the Chambers & Partners UK Bar Awards 2021 and at the Legal 500 Awards 2023.

A substantial part of Jonathan’s work concerns ultra-high-net-worth private trust litigation and associated advice. This encompasses the spectrum of domestic litigation, offshore work, trusts and divorce disputes and work with a fraud or other asset tracing element. His work involves a wide range of jurisdictions, from Jersey and Guernsey to Bermuda, the BVI, the Cayman Islands and Hong Kong. He commonly leads large teams on his trust matters and enjoys working as part of a large group.

The vast majority of his cases are confidential, but for example he has recently been involved in complex litigation in Jersey, Guernsey, Hong Kong, and Bermuda, to name a handful. e.g.

  • He recently appeared successfully before the Hong Kong Court of Final Appeal in the leading case on Quistclose trusts in that jurisdiction.
  • He recently acted in a very complex and large scale domestic trusts restructuring application, reported at [2024] EWHC 2784 (Ch).
  • He is centrally involved in an extremely large scale Jersey trust restructuring.
  • He is presently involved in a number of other multi-$bn contentious offshore and overseas trust disputes.
  • He is involved in two long running Guernsey disputes, both of which have involved trips to the Guernsey CA;
  • He has been involved in a number of long running ultra high-net-worth trust and divorce cases both in England and abroad;

Over recent years, a significant amount of his trusts work with an international element has concerned attacking and defending complex offshore structures, whether in the divorce context or in offshore proceedings involving fraud and other linked routes of attack. He has significant expertise in the divorce context and is often instructed as part of a family team.

On the domestic side, he acts in rectification, VTA and other similar court cases concerning trusts and estates, and frequently finds himself in the Chancery Division and Family Division on such cases.

He has longstanding experience in the Family Division having for example acted in the Tchenguiz Imerman v Imerman divorce and in cases like TM v AH [2016] EWHC 572 (Fam) about the joinder of offshore trustees.

Commercial disputes

Jonathan is consistently ranked in Chambers Global and Chambers & Partners UK Bar for his civil fraud and offshore work. 

A significant amount of Jonathan’s work concerns business and commercial disputes, particularly those relating to:

  • Civil fraud
  • Asset tracing
  • Financial services
  • Regulatory issues
  • Insolvency
  • Company and partnership issues

Jonathan’s work in these areas frequently overlaps with his offshore and trusts practices, many of these disputes having an international element, involving fraud or heavy factual disputes, and involving fiduciaries acting in a financial services context. He also has significant experience on the domestic side of the Upper Tribunal’s financial services jurisdiction and financial services judicial review.

On the commercial side, by way of example, over the last year or two:

  • He has appeared successfully before the Hong Kong Court of Final Appeal in the leading case on Quistclose trusts in that jurisdiction, China Life Trustees Ltd, arising out of bond issue by China Life.
  • He has dealt with a multi-billion $ African fraud claim.
  • He has been brought in to deal with a number of very high value disputes and commercial issues with a trust element in England and abroad involving high profile entities.

On the civil fraud side, to take some recent examples:

  • He is involved in a number of large ongoing currently confidential offshore cases across a range of jurisdictions involving allegations of fraud and other linked wrongdoing.
  • He has been involved in obtaining injunctions in offshore asset recovery proceedings.
  • He has been involved in a number of pensions liberations fraud and tracing cases, such as the landmark Pensions Regulator v PAYAE & ors [2018] case.

Previously, by way of examples:

  • He acted successfully as part of the claimants’ team in ITS v GP Noble [2009-2013], which involved fraud proceedings in a number of jurisdictions, a number of significant hearings and parallel criminal proceedings.
  • He acted successfully as part of the claimants’ team in the Court of Appeal in ITS v Susan Morris [2011-2013] in tracing the proceedings of fraud into a divorce settlement.
  • He was involved in litigation concerning the largest alleged fraud in recent Latvian history.

On the regulatory side, for example:

  • He has been involved in the recent leading cases before the Upper Tribunal (Tax and Chancery Chamber) concerning the limits of the jurisdiction of the Upper Tribunal in financial services matters.
  • He often acts in relation to regulatory investigations.
  • He has been involved in a number of pieces of financial services judicial review matters, including in relation to the life insurance industry.

As far as insolvency is concerned, much of his pensions work takes him into the insolvency arena, and he frequently advises alongside or acts together with insolvency counsel. Examples of his reported insolvency cases include:

  • Nortel & Lehman v TPR [2010-2013] (first instance, CA and SC- when a statutory debt ranks as a provable debt or expense).
  • Singer & Friedlander [2013] (calculation of debts in insolvency).
  • Gleave v PPF (proof for s.75 debts in insolvency).
