Maile v Maile [2025] EWHC 2494 (Ch): Where Capacity Meets Knowledge and Approval
The High Court’s decision in Maile v Maile [2025] EWHC 2494 (Ch) has already been cited with approval in subsequent Chancery judgments. Although the full judgment has not (at the time of writing, 31 March 2026) been published on the Courts and Tribunals Judiciary website, it was expressly referenced in Scott v Scott [2025] EWHC 2796 (Ch), a later decision handed down in October 2025. In Scott, Adam Johnson J noted that Michael Green J in Maile considered a now‑familiar point about the interaction between the Banks v Goodfellow capacity test and the separate requirement of knowledge and approval, but did not need to reach a concluded view on the controversy identified in Leonard v Leonard [2024] EWHC 321 (Ch) (as summarised in Scott). This cross‑reference gives valuable insight into how Maile is being understood and used.
What We Can Say with Confidence from the Official Record
Neutral citation and court. Maile v Maile is a Chancery Division decision from 2025 with neutral citation [2025] EWHC 2494 (Ch). It was heard by Michael Green J. This is confirmed by the way the case is cited by Adam Johnson J in Scott v Scott.
Capacity vs knowledge and approval. In Scott, the court discussed Joanna Smith J’s proposition in Leonard v Leonard that the Banks v Goodfellow capacity assessment is “transaction and issue‑specific”. Some parties argued that this strays into the territory of knowledge and approval. Scott records that in Maile, Michael Green J faced a similar point but regarded it as unnecessary to decide it. This positions Maile as part of the line of recent authorities scrutinising, but not finally resolving, the precise boundary between testamentary capacity and knowledge and approval.
Why the Maile Reference Matters
The Scott judgment uses Maile to illustrate judicial caution about collapsing the two distinct enquiries of capacity and knowledge and approval into one. The message is twofold:
Keep the tests conceptually distinct. Banks v Goodfellow remains the test for capacity; knowledge and approval is a separate requirement. The fact that capacity is assessed in the context of the actual will does not mean the two tests are the same exercise. Scott seats Maile within that careful, orthodox approach.
Fact‑sensitivity and evidential discipline. By acknowledging Maile’s treatment of the issue without needing to determine it, Scott underlines that many will disputes turn on granular expert and lay evidence, not just abstract doctrinal debate. The court’s reluctance to decide more than is necessary reflects a preference to ground outcomes in the specific evidential matrix.
Practical Implications for Contentious Probate Practitioners
Although the full text of Maile is not yet available on the official judiciary site, its deployment in Scott supports several practice points that PA Duffy & Co’s private client and disputes teams will recognise:
Frame capacity and knowledge/approval separately. Plead, particularise, and evidence each head distinctly. Do not assume that weaknesses in one will automatically carry over to the other. Scott’s discussion—citing Maile—cautions against eliding the two.
“Transaction‑specific” remains live but nuanced. The courts accept that capacity is assessed in the context of the instrument actually executed, yet remain vigilant not to convert capacity into a de facto knowledge/approval test. Expert evidence needs to address both the decision‑making ability (capacity) and the testator’s actual understanding of the will (knowledge/approval).
Be rigorous with expert and contemporaneous medical evidence. Scott shows the decisive role of carefully weighed expert opinions and contemporaneous records when real doubt is raised about capacity; the burden then lies on the propounder to prove capacity. Practitioners should marshal records and testimony that speak to both the Banks v Goodfellow limbs and the testator’s understanding at execution.
Proprietary Estoppel Context: Cautious Lessons
Many recent farming and family business disputes have tested the limits of proprietary estoppel alongside probate challenges. Scott explicitly cites Maile in its doctrinal discussion; taken together, these cases signal that:
Assurances, reliance, detriment, and unconscionability are scrutinised finely. Courts are applying a stringent lens to whether alleged assurances were sufficiently clear and whether any reliance produced detriment that makes non‑enforcement unconscionable. While Maile’s full reasoning is not on the judiciary website, Scott’s treatment and the trend of recent Chancery decisions indicate a cautious, evidence‑heavy approach in this area.
Take‑Aways for PA Duffy & Co Clients
Plan and document. For testators, contemporaneous medical capacity assessments and clear will‑file notes remain crucial. For families operating farms or family businesses, written agreements documenting succession intentions help avert later disputes over informal promises.
Plead distinctly; prove meticulously. Where both probate challenges and estoppel claims are advanced, ensure each ground is fully evidenced in its own right. The courts are resistant to short‑cuts between capacity, knowledge/approval, and equitable relief.
Expect careful judicial calibration. As illustrated by Scott’s discussion of Maile, the Chancery Division continues to calibrate the interface between capacity and knowledge and approval without conflating them, and to treat proprietary estoppel as an exceptional, fact‑dependent remedy.
Source Note and Limitations
The analysis above draws on the express discussion of Maile v Maile in Scott v Scott [2025] EWHC 2796 (Ch), particularly paragraphs addressing the relationship between Banks v Goodfellow and knowledge and approval, where Adam Johnson J records that Michael Green J in Maile made similar observations but did not need to decide the point. The Scott judgment is available on the Courts and Tribunals Judiciary website and is the authoritative basis for the propositions quoted here.
As at 31 March 2026, the Maile v Maile judgment itself does not appear on the Judiciary website. If and when the official text is published, a fuller case summary (including facts, issues, findings, and outcome) can be provided with direct citation to the judgment.
