Matthew Mills

Matthew is ranked in wills, trusts and estates matters in both of the leading legal directories, with solicitors recently reporting that he is “an exceptional advocate” who “relates to clients incredibly well and puts them at ease” (The Legal 500, 2024). Matthew’s work covers the full spectrum of private client practice, from substantial and multi-jurisdictional trusts and estates to a will allegedly written by hand on the back of a coffee-stained letter.

Matthew regularly advises personal representatives and beneficiaries in relation to wills and the administration of estates, including:

• Advising on want of knowledge and approval and testamentary incapacity in relation to an estate worth c.£15 million
• Advising the executor of a c.£10 million multi-jurisdictional estate on how to finalise the administration when a beneficiary refuses to agree the estate accounts
• Advising beneficiaries on executors’ expenses and solicitors’ professional negligence in relation to an estate worth c.£8 million
• Advising beneficiaries on a claim for an account in relation to an estate worth c.£6 million

• Advising clients on claims under the Inheritance (Provision for Family and Dependants) Act 1975 against multi-million-pound estates.

Matthew also regularly represents personal representatives and beneficiaries in litigation relating to estates. For example, his recent court work has involved:

• Successfully representing a beneficiary in a six-figure derivative claim brought on behalf of the estate against the executor in his personal capacity.

In addition to his estates work, Matthew advises and represents trustees and beneficiaries of lifetime trusts. For example, his recent trusts work has involved:

While offshore, Matthew worked on Z Trust [2020] JRC 072 (part of the leading litigation on insolvent trusts), the Crociani litigation, and Trico Ltd v Buckingham [2020] JCA 067 (a contractual dispute heard by the Jersey Court of Appeal). He also assisted with an expert report on Jersey trusts law in an international dispute worth $200 million, EFG Bank AG v Surewin Worldwide Ltd [2021] SGHC 227.

Matthew regularly gives seminars and webinars on private client topics. His recent talks have covered challenging wills, claims against personal representatives, and the duty to account (see here).

Matthew also writes on private client topics (see publications below), and previously taught and examined trusts law as a Teaching Fellow at UCL.

Matthew is one of just eight junior barristers in the country who are ranked in both Chambers and Partners and The Legal 500 for charity law. Clients describe him as “experienced beyond his years” (Chambers and Partners, 2024). Matthew regularly advises charities of all sizes on contentious and non-contentious matters and has represented charities as sole counsel and junior counsel in court. As a result, his work covers the full range of issues on which charities need advice and representation.

Out of court, clients have described Matthew as “invariably helpful, comprehensive, clear, and detailed in his advice” (Chambers and Partners, 2024). In his non-contentious practice, Matthew has advised various charity trustees on questions relating to governance, including:

In his contentious charity law practice, solicitors have described Matthew as “extremely client-friendly and exceptional on his feet” (The Legal 500, 2024). Matthew has advised and represented a range of charities in disputes, including:

Matthew has also published several academic and practical articles on charity law topics, including the registration of grant-making charities and the Supreme Court’s decision in Lehtimaki v Cooper [2020] UKSC 33 (see publications below).

Matthew previously taught charitable trusts to undergraduates as a Teaching Fellow at UCL.

Matthew practises extensively in all aspects of property law alongside teaching Land Law at the University of Oxford.

Matthew has frequently appeared in the High Court and County Court on bankruptcy petitions, winding-up petitions and other insolvency matters, including without notice applications. He acts for debtors, petitioners and insolvency practitioners. In his recent work, Matthew has successfully represented the petitioning creditor in a disputed bankruptcy petition relating to a £2.25 million debt, and obtained orders extending long-running administrations for insolvent companies with over £10 million of assets. He also successfully obtained one of the first compensation orders against a disqualified director for making a fraudulent application for a ‘bounce back loan’ during the pandemic.

Out of court, Matthew has recently advised an insolvency practitioner on an antecedent transaction claim in relation to a £4 million property, and advised the Insolvency Service on the merits of a potential £32 million claim against it for breach of the statutory duty of care.

Matthew has also developed a broad company law practice. He has advised on directors’ rights, duties and remuneration, the rights of a beneficiary of a trust of shares, and the rectification of the register of companies. In his recent court work, he has successfully defended a director in a claim for the return of his remuneration and expenses, and persuaded a court that a claim issued by one director against the other was started with the defendant director’s delegated authority.

During the pandemic, Matthew presented webinars on the latest insolvency cases and limitation periods in insolvency law (see here).

Matthew’s practice encompasses the full scope of commercial law. His recent work has raised issues of contractual construction, contractual variation, the enforceability of penalty clauses, and the delivery up of prize racehorses.

Matthew has experience of contractual disputes from the pre-action stage to trial. He has recently represented the defendant to a debt and unjust enrichment claim worth c.£900,000, and advised trustees on a claim for misrepresentation against the other parties to a six-figure settlement.
