A five-day final hearing concerning assets of over £20m, the majority illiquid business wealth, in which the wife sought to escape a valid pre-nuptial agreement on the basis that its full implementation would produce a highly uneven outcome. The court upheld the agreement, construed it narrowly, and confirmed that departure from a valid PNA is confined to a needs assessment, not a route back into sharing.

The parties signed a pre-nuptial agreement shortly before their marriage, negotiated by solicitors on both sides with mutual disclosure. As the marriage broke down , the wife initially declined to acknowledge the agreement existed and was found, on the balance of probabilities, to have deliberately removed the signed copy from the husband's file. The husband reconstructed it from contemporaneous emails. The wife argued that even if valid, the agreement should not be fully implemented because of the scale of imbalance it would produce between her and the husband's predominantly illiquid business wealth.
HHJ Hess found the agreement valid and binding under Granatino v Radmacher [2010] UKSC 42, construed it as excluding the husband's partnership share and later, unanticipated funds from sharing, and held — following Brack v Brack [2018] EWCA Civ 2862 — that neither counsel could identify any authority departing from a valid PNA other than on grounds of need. An uneven outcome was not itself a basis for departure; that is often the very purpose of a PNA. The court then carried out a generous needs assessment: monthly maintenance for the wife, Duxbury-capitalised and discounted for her prospective earning capacity and other capital. The final award to the wife included a half share of the family home on Mesher terms.
Where a pre-nuptial agreement is found valid, litigants should not expect the size of the resulting imbalance, by itself, to unlock a sharing claim. The court's departure analysis will almost always be confined to needs — albeit assessed generously where resources allow. Conduct around disclosure of the agreement itself (the wife's attempt to conceal the signed copy) did not defeat the agreement, but it materially damaged her credibility on the separate question of what she believed it covered.
This case is a strong teaching example of the limits of a PNA challenge for self-represented litigants who may be advised (or hope) that an uneven outcome is itself grounds for departure. A McKenzie Friend can help a client understand early that, absent vitiating factors, the realistic target is a well-evidenced needs case — and can assist with the kind of detailed spending schedules that carried real weight in this judgment.
Pre-nuptial agreement (PNA)
A written agreement signed before marriage setting out how assets should be divided if the marriage ends.
Needs assessment
Working out what a party actually requires for housing and income, as opposed to a full 50/50 sharing of all assets.
Duxbury capitalisation
A standard financial calculation used to convert an ongoing maintenance claim into a single lump sum, based on tables in 'At A Glance'.
Mesher order
An order allowing one party to stay living in the family home for a set period (e.g. until children finish education) before it is sold and proceeds divided.
Wells sharing
A way of sharing future, uncertain business income by giving each party a percentage share of it as and when it's received, rather than a fixed sum now.
