Harriet PriceWhen Jemima Goldsmith walked down the aisle on 12 September 2026 flanked by her sons Sulaiman, 29, and Kasim, 27, she marked the end of a chapter that had defined a generation of headlines — and, for family solicitors across England and Wales, sparked an immediate wave of client inquiries. Her marriage to Cameron O'Reilly, a 62-year-old Irish-Australian financier and son of the late media tycoon Sir Anthony O'Reilly, was celebrated in a private ceremony at what appeared to be a private château, attended only by close family. By the following morning, the wedding photographs had gone viral. The question family lawyers found themselves fielding within days was not about the dress. It was: should we have a prenup?
A High-Profile Reunion With Complex Finances
Goldsmith, 52, is one of Britain's best-known public figures — an award-winning screenwriter, documentary producer, and former wife of imprisoned former Pakistani Prime Minister Imran Khan, from whom she divorced in 2004. O'Reilly brings substantial financial interests across Ireland and Australia, and a blended family of his own: four children from a previous relationship, including daughters Sasha and Tara and sons Elliot and Oscar, all of whom played roles in the ceremony alongside Jemima's three children.
According to Hello! Magazine and reports confirmed by family members on social media, the ceremony was intimate, private, and deliberately low-key. The couple reportedly met through their shared work in film and documentary production and had been together for approximately a year before marrying.
It is precisely this combination — substantial wealth, blended families, second marriage, and a significant age gap — that family law solicitors have in mind when they argue that the UK's legal framework has failed to keep pace with how modern couples actually live.
What the Law Currently Says — and What Is About to Change
Prenuptial agreements in England and Wales occupy a legally awkward position. Unlike in many European jurisdictions and US states, prenups are not automatically legally binding here. However, since the Supreme Court's landmark ruling in Radmacher v Granatino [2010] UKSC 42, English courts have given prenuptial agreements decisive weight when dividing assets on divorce — provided specific conditions are met: both parties must have received independent legal advice, both must have made full financial disclosure, and neither must have signed under duress or with inadequate time to reflect.
That framework is now under formal review. In June 2026, the government published a consultation on GOV.UK titled A Fairer End to Relationships, proposing that "qualifying nuptial agreements" should become contractually binding on courts, subject to statutory safeguards designed to prevent unfair outcomes. If enacted, this would represent the most significant reform to English matrimonial finance law in decades — giving couples far stronger certainty about how their assets will be treated if a relationship ends.
For couples marrying in autumn 2026, the timing is significant: an agreement drafted now should be designed to meet the anticipated qualifying standards, not merely the current Radmacher test. Solicitors specialising in matrimonial finance are already drafting to the higher standard in anticipation.
As seen with other high-profile couples facing the prenup question in 2026, the gap between public perception of prenups and their actual legal operation in England and Wales is wider than most people expect.
Why Remarrying in Your 50s Carries Unique Legal Stakes
Second marriages after the age of 50 involve a fundamentally different financial landscape than first marriages entered in your 20s or 30s. Both parties typically arrive with decades of accumulated wealth: property owned outright, pension pots built over 25 to 30 years, business interests, investments, and in many cases expected or received inheritances. There are also, often, adult or teenage children from previous relationships whose inheritance expectations are legally invisible without explicit documentation.
Family solicitors routinely identify three asset categories where remarrying couples face the greatest financial risk without a prenuptial agreement:
Pre-marital property: A home purchased before the marriage is not automatically ring-fenced on divorce. Courts apply the sharing principle alongside a needs-based assessment, and pre-marital property can be drawn into the matrimonial pot — particularly if the marriage was long-lasting or the non-owning spouse has a demonstrable housing need.
Pension wealth: UK pension sharing orders allow a court to award up to 100% of a partner's pension on divorce. For someone who has spent three decades accumulating a defined contribution pension, this is often the single largest financial exposure in a second marriage without legal protection.
Inheritance and family assets: Funds received as an inheritance or expected from ageing parents are vulnerable to matrimonial claims unless explicitly documented. Without a prenup, a court cannot easily distinguish between inherited wealth and jointly accumulated matrimonial assets.
When Good Faith Is Not Enough: A Scenario That Plays Out Every Week
Consider a situation that UK family solicitors handle several times a year. Margaret, 53, a marketing director in Bristol, owns a four-bedroom home worth £520,000 outright — purchased with her first divorce settlement and a decade of savings. She has two teenage daughters she intends to leave the property to. She marries Robert, 58, a semi-retired architect whose main assets are a self-invested personal pension valued at £410,000 and a minority stake in a small practice worth approximately £75,000.
Neither signs a prenuptial agreement. Both believe the law will recognise that their respective assets are their own.
Three years into the marriage, the relationship breaks down. Under English family law, the starting point for asset division in a marriage is broadly equal — but the court also applies a needs assessment. If Robert is found to have a reasonable housing need, and if the total asset pool (including Margaret's home) is brought into the matrimonial calculation, Margaret could face a claim on up to 40% of her home's equity — a figure in the region of £208,000. Her daughters' expected inheritance is not legally protected simply because she intended it for them.
Had a qualifying nuptial agreement been in place — explicitly ring-fencing Margaret's home as pre-marital wealth and carving out Robert's pension in reciprocal terms — a court following current Radmacher principles would give it substantial weight. Under the proposed 2026 reform, the agreement could be fully binding on the court.
The cost of a properly drafted prenuptial agreement reviewed by two independent solicitors: approximately £2,000 to £4,000 in professional fees. The cost of contesting a contested asset claim in the Family Division of the High Court: routinely upwards of £30,000 per party, before any settlement is reached.
This is not a theoretical scenario. UK family solicitors are reporting a sharp rise in prenup enquiries from couples in their 40s and 50s, driven precisely by the combination of higher asset values, more complex blended families, and growing awareness that the law does not automatically protect pre-marital wealth.
Practical Steps for Anyone Remarrying in 2026
The solicitors most commonly advising on prenuptial agreements this year recommend the following steps, ideally beginning several months before the wedding:
Start early, not late. Courts are deeply sceptical of prenuptial agreements signed within four weeks of the wedding. The practical minimum is 28 days; three to six months before the ceremony is standard best practice and significantly strengthens the agreement's weight in court.
Disclose everything. Full financial disclosure — bank accounts, property valuations, pension statements, business interests, debts, and expected inheritances — is a prerequisite. An agreement signed without complete disclosure is vulnerable to challenge and may be set aside entirely.
Appoint separate lawyers. Both parties must receive independent legal advice from their own solicitor. Sharing one lawyer, however trusted, undermines the agreement's validity under current Radmacher principles and would likely disqualify it under the anticipated 2026 qualifying standards.
Consider a postnuptial agreement if the moment has passed. If the wedding has already taken place without a prenup, or if a significant financial change occurs after marriage — an inheritance received, a business sold, a property purchased — a postnuptial agreement can be drafted to reflect the new reality. Courts treat postnuptial agreements with similar weight to prenups.
Account explicitly for children. Blended families should document clearly how specific assets will be treated in relation to children from previous relationships, particularly if those children are minors or not yet financially independent.
Plan for the reform timeline. The government's A Fairer End to Relationships consultation is expected to move to enabling legislation within the next 18 to 24 months. Agreements drafted now should be future-proofed to meet the anticipated qualifying standards, not merely the current test.
What Jemima's Wedding Tells Us About Modern Britain
Whether Jemima Goldsmith and Cameron O'Reilly have a prenuptial agreement is their business alone. What their September wedding illustrates is a pattern visible across the country. According to the Office for National Statistics, remarriage rates among people over 45 in England and Wales have risen steadily over the past decade, with 38% of all UK marriages now involving at least one partner who has been previously married. That is a number with significant legal implications — and a significant advice gap.
For couples entering later-life second marriages with combined assets above £200,000, a conversation with a qualified family law solicitor is not optional. It is the difference between a financial framework and a financial gamble.
