Standish v Standish, One Year On: Why Pre-Nuptial Agreements Matter More Than Ever

If you have significant assets from before your marriage — an inheritance, a business you built solo, or wealth transferred to you for tax planning — the Supreme Court’s ruling in Standish v Standish should be on your radar. Over a year on, it’s still shaping how family lawyers advise clients on protecting pre-marital wealth, and it makes the case for a pre-nuptial agreement stronger than ever.

What happened in Standish v Standish

The case involved a husband who transferred around £80 million of his own pre-marital assets into his wife’s name, primarily for tax planning purposes. When the couple later divorced, the question for the courts was whether those transferred assets had become “matrimonial property” — and therefore fair game for equal sharing — simply because they were now legally in the wife’s name.

The Supreme Court said no. It ruled that merely holding assets in a spouse’s name does not automatically make them matrimonial. For assets to be treated as shared marital property, there needs to be clear evidence that they were genuinely intended to be shared — for example, through how the couple used or integrated them into joint life, not just where the paperwork happened to sit. Since the transfers here were made for tax efficiency and with the children’s long-term benefit in mind, not as a gift to the marriage, the assets kept their non-matrimonial character and were largely excluded from equal division.

Why this matters if you’re getting married

The ruling draws a clearer — but still fact-sensitive — line between “yours” and “ours.” That’s good news in principle, but it also means outcomes hinge heavily on evidence: how an asset was used, discussed, and treated throughout the marriage. Without documentation, that can turn into a lengthy and expensive argument during divorce proceedings.

This is exactly the gap a pre-nuptial agreement is designed to close. Rather than relying on a court’s after-the-fact interpretation of intentions, a pre-nup lets both parties set out, in writing and in advance, which assets are to remain separate and which are intended to be shared. Courts are increasingly willing to uphold these agreements, provided they are entered into freely, with full financial disclosure, and with each party having received independent legal advice.

Who should be paying attention

A few groups should take particular note of the Standish decision:

Anyone bringing significant pre-marital wealth into a marriage — inherited money, a family business, or assets built up before meeting their partner — now has stronger legal grounding for keeping that wealth separate, but only if it’s properly documented from the outset.

Couples using inter-spousal transfers for tax or estate planning reasons should be especially careful. The ruling shows that transferring assets into a spouse’s name for tax efficiency does not, by itself, convert those assets into shared marital property — but this can still be disputed and litigated without a written agreement confirming intent.

Anyone who has already married without a pre-nup can still benefit from a postnuptial agreement, which serves a similar function and can be put in place at any point during the marriage.

The practical takeaway

Standish v Standish reinforces a principle family lawyers have long advised on: intentions matter, but only if you can prove them. A pre-nuptial agreement turns an unwritten assumption into clear, enforceable evidence of what was meant to stay separate and what wasn’t.

If you’re entering a marriage with pre-existing assets, or plan to make transfers for tax or estate planning purposes, now is the time to get specialist advice and put a properly drafted agreement in place — before, not after, a dispute arises.
