Key Takeaways
- There is no fixed legal definition of a high net worth divorce, but cases typically involve combined assets exceeding £1 million.
- The courts in England and Wales divide assets using the Section 25 checklist set out in the Matrimonial Causes Act 1973, with the welfare of any children as the first consideration.
- Pre-marital wealth, inheritances, and gifts are not automatically shared on divorce, as confirmed by the Supreme Court ruling in Standish v Standish [2025] UKSC 26.
- Prenuptial and postnuptial agreements are not automatically legally binding but carry significant weight where they are properly drafted and fairly entered into.
- Both parties must provide full financial disclosure through a Form E. Hiding assets is a serious matter and courts can impose sanctions.

Frequently Asked Questions
What counts as a high net worth divorce?
There is no fixed legal definition. High net worth divorce generally refers to cases where combined assets exceed £1 million. These cases typically involve multiple properties, business interests, pensions, investments, offshore assets, and sometimes trusts. The same legal framework applies as in any divorce, but identifying, valuing, and dividing those assets is considerably more complex.
How does the court divide assets?
The courts in England and Wales do not apply a rigid formula. Instead, judges work through a checklist of factors set out in Section 25 of the Matrimonial Causes Act 1973, which governs how finances are divided on divorce. The first consideration is always the welfare of any children of the marriage. After that, the court weighs up each party’s income and financial resources, their needs, the length of the marriage, contributions made by each spouse, and the standard of living during the marriage. The starting point is generally equal division of matrimonial assets, though the court has broad discretion to depart from this where fairness requires it.
What is the difference between matrimonial and non-matrimonial property?
Matrimonial property refers to assets built up during the marriage through the couple’s joint efforts. Non-matrimonial property includes wealth brought into the marriage by one party, as well as gifts and inheritances received during it.
The Supreme Court’s ruling in Standish v Standish [2025] UKSC 26 clarified this distinction significantly. The Court confirmed that the sharing principle applies only to matrimonial property. Pre-marital wealth, inherited assets, and assets transferred between spouses for tax planning purposes do not automatically become matrimonial simply by being transferred. What matters is how those assets were treated during the marriage and whether both parties intended them to be shared.
What about prenuptial and postnuptial agreements?
These agreements are not automatically legally binding in England and Wales, but they carry significant weight. Courts will generally uphold them where both parties entered the agreement freely and without pressure, each had their own independent legal advice before signing, and there was full and honest financial disclosure from both sides at the time. The agreement must also not produce an outcome so unfair that the court feels compelled to override it, for example where one party would be left in financial hardship.
What are the financial disclosure requirements?
Both parties must provide full and frank disclosure of all assets worldwide, including income, property, business interests, pensions, investments, and debts. This is done through a document called a Form E. Deliberate non-disclosure is serious. The courts in England and Wales can draw adverse inferences against a party who fails to disclose fully. Where there are concerns a spouse may be hiding or dissipating assets, it is possible to apply for a freezing injunction to protect those assets while proceedings continue. In extreme cases, courts can impose cost penalties or other sanctions.
How are business assets dealt with?
Business assets require formal valuation, usually with input from forensic accountants or independent experts. Courts aim to avoid forcing the sale of a viable business where possible, recognising that doing so could destroy its value or affect the livelihoods of those who depend on it. Where a clean division is needed, options typically include one party buying out the other’s interest in the business, or offsetting the value of the business against other assets in the settlement, for example one party retaining the business while the other receives a larger share of the family home or other assets. The right approach depends on the nature of the business and the overall asset picture.
How long does a high net worth divorce take?
The civil divorce process takes a minimum of 26 weeks from the date the court issues the application. In practice, administrative lead times in 2026 mean most divorces take between seven and ten months. Where financial proceedings are contested, the timeline is considerably longer. Complex financial cases often take one to two years to resolve, particularly where there are disputes over valuations or offshore assets.
