The recent Supreme Court decision in Standish v Standish marks a significant development in English Family Law, offering long-awaited clarification on when non-matrimonial assets may become subject to the sharing principle through a process often described as “matrimonialisation.” The judgment provides a structured framework for distinguishing between matrimonial and non-matrimonial property and limits the circumstances in which the latter may be divided on divorce.
Standish v Standish Background
The case arose from the divorce of Mr and Mrs Standish, involving substantial wealth accumulated by the husband prior to the marriage. In 2017, Mr Standish transferred approximately £77.8 million to his wife as part of a tax planning arrangement. At first instance, the High Court held that these assets had become matrimonial property and awarded the wife £45 million, applying an unequal division (60/40) to reflect the husband’s unmatched contribution.
On appeal, however, the Court of Appeal took a different view. It concluded that the majority of the transferred assets had retained their non-matrimonial character, reducing the wife’s award to £25 million. The wife’s subsequent appeal to the Supreme Court has now been dismissed, with the Supreme Court endorsing the Court of Appeal’s ultimate conclusion.
The Supreme Court’s Key Principles
In a unanimous judgment, the Supreme Court articulated five key principles governing the application of the sharing principle and the concept of matrimonialisation:
Conceptual Distinction Between Asset Types
The Court reaffirmed a clear distinction between matrimonial property, typically the fruits of the marriage or joint endeavour, and non-matrimonial property, such as assets acquired before the marriage or by gift or inheritance.
Scope of the Sharing Principle
The Court confirmed that the sharing principle applies only to matrimonial property. While non-matrimonial property may still be relevant under the “needs” or “compensation” principles, it is not subject to sharing as a matter of course.
Starting Point of Equal Division
Where assets are classified as matrimonial, the default position remains equal division between spouses, subject to departures where justified.
Treatment of the Asset Over Time
A central factor in determining whether matrimonialisation has occurred is how the parties have treated the asset during the marriage. Evidence that an asset has been treated as shared over time may support its reclassification as matrimonial property.
Tax Planning Transfers Between Spouses
The Court held that transfers of assets between spouses for tax planning purposes will not normally constitute matrimonialisation. Such transfers, without more, do not demonstrate an intention to share the asset.
Application to the Facts
Applying these principles, the Supreme Court agreed that 75% of the transferred assets remained non-matrimonial, while 25% had become matrimonial and should be shared equally. The Court found no evidence that the transferred assets had been treated as shared by the parties. Instead, the transfer was clearly motivated by tax efficiency rather than any intention to benefit the wife or integrate the assets into the marital partnership.
Implications for Family Law
The decision in Standish v Standish provides much-needed clarity in an area that has long been characterised by uncertainty.
It confirms that:
The sharing principle is confined to matrimonial property, reinforcing the importance of the source of wealth.
Matrimonialisation requires more than legal title or intra-spousal transfers; it depends on demonstrable intention and conduct.
Tax-driven transfers between spouses will generally not, in themselves, expose assets to equal division.
The judgment establishes a clearer framework and reduces the scope for arguments regarding the sharing of non-matrimonial wealth.
Conclusion
Standish v Standish represents a pivotal clarification of the law governing financial remedies on divorce. By drawing firmer boundaries around the concept of matrimonialisation, the Supreme Court has reinforced the integrity of the sharing principle while preserving flexibility in appropriate cases. The decision is likely to have a lasting influence on how high-value divorce cases are argued and decided in England and Wales.
