Prenuptial Agreements in Divorce: What a £26m Case Means for Couples in Northern Ireland

< Back to Legal Insights

In his latest legal insight, Associate Director Ryan Elliott discusses a recent English divorce case involving assets worth £26m, which highlights the increasing judicial recognition of Prenuptial Agreements.

A £26m divorce case puts Prenups in the spotlight

In this case, the couple had been in a relationship since January 2010. They signed a Prenup in January 2012, married in February 2012, and went on to have two children. The marriage broke down after 12 years in May 2024. The couple were both in their forties. The husband had enjoyed a lucrative career in private equity whilst the wife had largely sacrificed her own employment to care for the children and maintain family life at home.

The couple’s wealth was £26m, comprising £8m of realisable assets such as properties and bank accounts and £18m of non-realisable assets including the husband’s business interests. The husband’s annual income was also substantial.

Why the court largely upheld the Prenuptial Agreement

The dispute in court centred on the couple’s differing interpretation of their Prenup. The Prenup sought to prevent the wife from advancing a divorce claim on the assets held in the husband’s sole name. The husband argued that the agreement should be honoured, while the wife challenged that position. Despite describing the Prenup as “a piece of sub-optimal drafting”, and despite one possible instance of non-disclosure, the Judge ruled that the Prenup had been validly entered into and largely upheld its terms.

Citing the 2010 seminal Supreme Court decision of Radmacher v Granatino*, the Judge recognised the principle that “the court should give effect to a nuptial agreement that is freely entered into by each party with a full appreciation of its implications unless in the circumstances prevailing it would not be fair to hold the parties to their agreement.” The Judge further recognised that to depart from the terms of a Prenup in order to satisfy a claim beyond the needs of a spouse and any minor children would fail to give effect to the principle ratified by the Supreme Court.

How the court balanced the Prenup with family needs

The Judge found that there was no compelling reason to disregard the asset division as was intended and agreed within the Prenup, beyond ensuring that the wife’s needs and the children’s needs were properly met. The Judge therefore undertook a comprehensive assessment of those needs. The Judge ultimately ruled that the wife should receive just over £3.1m, in addition to her half interest in the matrimonial home and the right to occupy the matrimonial home for a time-limited period. Other than that right of occupation, a clean break was ordered. As was to be expected, and not a point of contention, the Judge made separate provision for the husband’s maintenance of the children. The husband otherwise retained the vast majority of the assets. In his concluding remarks, the Judge opined that the ruling respected the terms of the Prenup, appropriately met the wife’s needs, and was fair in all the circumstances.

Why more couples are considering Prenups

As published by the BBC on 29 July 2026 **, UK research suggests that around 10% of couples now have a Prenup, following a shift towards greater recognition by the courts and greater awareness amongst the public.

In Northern Ireland, we are seeing a significant increase in people exploring Prenuptial Agreements before marriage, from younger individuals who have received or expect to receive lifetime gift or inheritance, entrepreneurs with positive future prospects, to divorcees, individuals who are marrying later in life, and older couples who are in the midst of estate planning.

For those planning to marry, or those already married, Nuptial Agreements can help protect wealth and reduce the financial uncertainty and conflict that may arise from a future divorce.

Whilst the decision in this English divorce is not binding on the Courts of Northern Ireland, the underlying Supreme Court principle that guided the Judge’s rationale is binding on our Courts, and so this decision provides welcome guidance for wealthy fiancés who are considering a Prenup.
