Thomas Fletcher


Call: 2009

“Thomas is a joy to work with. You can always be confident that no stone is left unturned and that all eventualities, even in the most high pressured and complex of cases, have been considered.”

Chambers & Partners 2025

Thomas Fletcher is a trusts and estates specialist. He is regularly instructed in complex, high-value claims both in England and international jurisdictions concerning trusts and estates matters. He has appeared as Counsel at every level of the court hierarchy in England and Wales from the High Court to the Supreme Court. He has also appeared three times before the Judicial Committee of the Privy Council.

He is the editor of the leading practitioner textbooks for trusts and estates work, Lewin on Trusts and Theobald on Wills. He is also one of the editors of the leading journal, Trusts & Trustees.

His practice covers the full range of contentious and non-contentious private client work, ranging from (on the trusts side) trust administration applications including Beddoe and Public Trustee v Cooper proceedings, breach of trust claims, trustee removal applications, variations of trust and all related trust drafting to (on the estates side) construction and rectification claims, contentious probate, claims under the Inheritance (Provision for Family and Dependants) Act 1975, executor removal claims, and breach of duty claims against personal representatives.

Thomas’s practice is based in England, but he has very considerable experience in overseas jurisdictions, including Bermuda, Guernsey, Jersey, Isle of Man, the Bahamas and the BVI. Many of his cases have a cross-border dimension and he is highly experienced in conflicts of laws issues as they affect the administration of trusts and estates.

He has been recommended for many years as a Leading Junior in trusts and estates work by Legal 500 (UK Bar and English Bar Offshore) and Chambers & Partners (UK Bar, Global and High Net Worth).

Related with his trusts and estates work, Thomas’s practice extends to commercial disputes which involve issues of trusts and estates law. He also has a growing practice in charities work, particularly related to the administration of charitable trusts and similar structures.

Areas of Expertise

Recent Cases

  • Viegas v Cutrale [2025] 1 WLR 1467 (2022 – 2025) – Instructed by Linklaters. Thomas successfully argued before the Court of Appeal that hundreds of claims for damages arising from an alleged cartel should be struck out for failure to obtain grants of representation in England to act for the relevant estates. The Court of Appeal’s judgment has been cited in several subsequent judgments for its important commentary on (i) the distinction between administration and succession under English law, and (ii) the requirement to obtain an English grant in relation to an estate where the deceased died domiciled abroad, even where the saisine principle applies under the law of the domicile.
  • Investec Trust (Guernsey) Ltd v Glenalla Properties Ltd [2019] AC 271 – Instructed by Macfarlanes and Mourant. Thomas acted in 10 appeals heard by the Privy Council from Guernsey. The judgment has been one of the most significant decisions in the trusts industry for many years due to the commentary on (i) a new rule of private international law based on the status of a trustee, (ii) the role of causation in breach of trust claims, (iii) the application of the rule in Henderson v Henderson in breach of trust claims and (iv) unjust enrichment.
  • Equity Trust (Jersey) Ltd v Halabi / ITG Ltd v Fort Trustees Ltd [2023] AC 877 – Instructed by Macfarlanes. Thomas acted in relation to combined appeals from Jersey and Guernsey heard by the Privy Council. These appeals were the first anywhere in the common law world to consider the order of priorities for an “insolvent” trust. The judgment has been hugely influential for that reason and has been cited in several courts in other jurisdictions, including the High Court of Australia.
  • ITG Ltd v Fort Trustees Ltd (2018 to 2024) – Instructed by Macfarlanes. Thomas acted for former trustees in relation to one of the first contested Alhamrani assessments of trustee costs anywhere in the common law. Three judgments were given by the Royal Court of Guernsey ([2020] GRC 020; [2021] GRC 007; [2022] GRC 003) and three judgments by the Court of Appeal of Guernsey ([2023] GCA 004; [2023] GCA 009; [2024] GCA 002).
  • In the Matter of the XYZ Trusts (2017 to 2024) – Instructed by Baker McKenzie and Carey Olsen. Thomas acted for trustees in proceedings in Bermuda concerning the restructuring of multiple valuable trusts. Two judgments were given by the Supreme Court of Bermuda in 2017 and 2022 ([2017] SC (Bda) 111 Civ; [2022] SC (Bda) 10 Civ).
  • Buchanan v Buchanan (2025) – Instructed by Birketts. Thomas acted for the claimants in proceedings for rectification and construction in relation to a trust deed where the existing drafting produced substantial potential tax liabilities. Thomas successfully argued that the trust deed should be rectified as sought.

Recent Cases

  • In the Matter of the Alpha, Beta & Delta Trusts (2023 ) – Instructed by Macfarlanes and Ogier. Thomas acts for the trustees in proceedings in Jersey concerning the restructuring of several high-value trusts.

  • Campbell v Campbell [2017] JRC 018 – Instructed by Dickinson Gleeson. Proceedings in Jersey in respect of a long-running dispute arising out of a family partnership concerning the beneficial ownership of shares in a Jersey company owned by the partnership. Judgment held for the first time in Jersey that the principles of common intention constructive trusts could apply outside a real property context and also included some of the first discussion of claims in unjust enrichment in Jersey.

Thomas has a strong interest in charities work and his trusts and estates practice regularly involves elements of charities law. His estates work also regularly involves advising on will disputes and administration issues involving gifts to charities. He is also one of the editors of Theobald on Wills and has primary responsibility for the chapters on charitable gifts in wills.

His recent work includes (i) advising unincorporated associations (e.g. sports and social clubs) on their trust arrangements and rules of membership and (ii) advising on potential claims against charitable trustees for breach of trust.

Thomas has a particular interest in commercial disputes which involve issues of trusts and estates law. He has considerable experience working with legal teams with expertise in several disciplines and enjoys the challenges of synthesising different areas of law.
