Associate Solicitor Emily Prince gives an update on the Supreme Court’s decision regarding matrimonial property and what this landmark ruling means for future financial disputes.
Following my previous blog on this case, on 2 July 2025, the Supreme Court delivered its judgment in the significant case of Standish v Standish, offering important clarification on the treatment of matrimonial and non-matrimonial assets in divorce proceedings.
This ruling will be helpful for both practitioners and individuals wishing to divorce, as it provides some clarification between matrimonial and non-matrimonial property.
Standish v Standish
The case was on a financial dispute between a divorcing couple. The wife argued that nearly £80 million, which her husband had transferred as part of long-term tax planning for their children, should be treated as matrimonial property and therefore subject to equal division. The husband maintained that these funds were intended for a trust benefitting their children and should remain outside the matrimonial pool.
The Supreme Court dismissed the wife’s appeal, ruling in favour of the husband. In doing so, the Court provided guidance on what constitutes matrimonial property and when the principle of equal sharing applies.
Understanding the Court’s reasoning on Matrimonial Property
Matrimonial property generally refers to assets that have been acquired or built up during the course of the marriage through the joint efforts of the couple, whether financial or not. These assets are typically subject to equal division upon divorce.
By contrast, non-matrimonial property includes assets brought into the marriage by one party or received individually through inheritance or a gift. These are not automatically subject to sharing, unless they become integrated into the couple’s shared financial life; a process often referred to as “matrimonialisation.”
A key takeaway from the Standish judgment is the Supreme Court’s firm endorsement of this distinction. The Court stated that: “the sharing principle does not apply to non-matrimonial property”.
In this case, the Court found that the c. £80 million in question retained its non-matrimonial status as it had been set aside specifically for the benefit of the children and was never treated by the couple as a joint asset. There was no evidence of it being used or intended for their mutual benefit, which would have suggested a shared intention.
Why is this guidance on Matrimonial Property important?
This ruling marks an important clarification in family law. It reinforces the principle that the equal sharing rule applies only to assets acquired through the joint endeavour of the marriage. Non-matrimonial assets remain distinct unless they are brought into the marital pot through the couple’s conduct.
For individuals navigating divorce, this decision highlights the importance of how assets are treated during the marriage. It also underlines the value of clear legal advice when it comes to financial planning, asset protection, and trust structures, particularly where significant wealth or family succession planning is involved.
Of course, the cases where the assets in question are so valuable do not constitute the majority, so it may be less straightforward to draw a line between the matrimonial and non-matrimonial assets. Needs are often the factor primarily considered by the court, so, if in doubt, about how this decision might impact your situation, or you would like tailored advice on asset division or trust planning in divorce, our family law team would be happy to help.
