The duty to declare every asset, trust and shareholding during divorce financial non-disclosure proceedings has never carried heavier consequences, and a run of recent court decisions makes clear that the family judiciary is in no mood to look the other way. From a 19-year marriage dissected in the High Court to a short-lived union undone by a misleading prenuptial agreement, the cases accumulating on the law reports paint a consistent picture: concealment is not a strategy, it is a liability.
The MK v SK Judgment: Trusts, Titles and the Reality of Wealth
The case of MK v SK [2026] EWFC 28 sits at the centre of recent debate. According to Paradigm Family Law, Mr Justice Peel addressed allegations of non-disclosure within financial remedy proceedings following a 19-year marriage. The wife alleged that the husband had failed to disclose assets forming part of a trust structure. The court agreed.
The detail, as reported by the Financial Remedies Journal, is instructive: the husband’s shareholding in the Group was held via Holdings Ltd, and the shares in Holdings Ltd had been placed in the first A Trust. On the face of it, a tidy corporate arrangement. In the eyes of the court, a structure that obscured rather than clarified the true extent of the husband’s resources.
Mr Justice Peel concluded that the husband had concealed wealth, finding that he enjoyed access to undisclosed assets held within the trust, some other structure, or by individuals on his behalf. The judgment reinforces what family lawyers have long argued: courts look beyond formal legal title to the reality of what a party can access and control. For family offices, trustees and the advisers who sit alongside them, that is a pointed reminder of the risks that informal arrangements carry when a marriage comes apart.
Prenuptial Agreements Are No Shield Against Divorce Financial Non-Disclosure
If MK v SK concerns the behaviour of a wealthy husband, the Court of Appeal’s decision in Helliwell v Entwistle demonstrates that divorce financial non-disclosure is emphatically not a gendered issue. The parties had a three-year marriage, preceded by a prenuptial agreement in which both stated they had ‘fully and frankly’ disclosed their financial resources and liabilities. The wife had not. She had failed to disclose assets amounting to 73% of her wealth, including her business assets and a 50% interest in property.
The Court of Appeal found that the omission was deliberate and sent the case back to the High Court to assess the husband’s needs afresh. The practical implication reaches well beyond this couple. Prenuptial disclosure is routinely presented in the form of a schedule or summary document, a format that is often high-level and, by its nature, easier to manipulate by omission. When that summary is accompanied by an explicit assertion that it is complete, any shortfall becomes not merely an administrative failure but a misrepresentation capable of undermining the entire agreement. With pre- and postnuptial agreements growing in popularity, the incentive for thorough disclosure before a marriage begins has rarely been clearer.
When Old Settlements Come Undone
The reach of the court’s scrutiny does not end at decree absolute. The Gohill litigation, which reached the Supreme Court in 2015, stands as the most arresting illustration of how far back the law will look. Mrs Gohill persuaded the Supreme Court to set aside a settlement order made 11 years earlier after evidence emerged of her former husband’s concealed wealth and money-laundering activity. Mr Gohill had by then been sentenced to 10 years in prison. The final determination of Mrs Gohill’s financial claims did not occur until May 2025, some 20 years after the separation, when the court was at last able to identify which assets were matrimonial property and untainted by his criminal conduct. She received the entirety of those identified untainted assets.
Around the same time, the Supreme Court reinforced the principle in Sharland. Mr Sharland, a successful software entrepreneur, had misrepresented the value of his shareholding in his software business. The court was clear: a dishonest spouse cannot benefit from the uncertainty they create, even where the precise impact of the non-disclosure on the outcome is difficult to quantify. Complexity is not an excuse, and ambiguity is not a defence.
The Harder Road for the Financially Weaker Spouse
Taken together, these cases offer a degree of reassurance to the less financially powerful spouse in a high-value divorce, but they also illuminate how difficult the path can be. Most people are not forensic accountants. Even commercially sophisticated individuals may lack the background or visibility into family wealth to evaluate what their higher-earning spouse has put before them. In longer marriages, financial expertise tends to concentrate in one spouse’s hands almost by default.
The challenge is compounded by timing. Allegations of divorce financial non-disclosure are frequently raised at the very outset of proceedings, before any evidence is available to test them. A divorcing spouse may arrive at a first meeting consumed by mistrust, convinced that assets are being hidden. The role of their adviser, in those early weeks, is not simply to review what has been provided but to probe, challenge and identify what is missing. Reviewing disclosure in good faith is not enough; rigorous early scrutiny, informed by an understanding of how complex wealth structures are assembled, is what the cases now demand.
The position the law takes is the same as it has been for decades: every spouse, whatever their wealth, owes a duty of full and frank disclosure. What has sharpened is the court’s appetite to hold that duty to account, in structures of any complexity, across any jurisdiction, and at any point in time. Hughes Fowler Carruthers notes that for ultra-high net worth individuals and their advisers, strong governance, clear documentation and anticipating future disclosure requirements are no longer optional considerations but essential ones.
