Ernesto & Kirsty Bertarelli: Britain's Richest Divorcee and the $476 Million Exit
A former Miss UK and a pharmaceutical billionaire ended their 21-year marriage amicably, making her Britain's wealthiest divorcee.
Key Facts
What Happened
Ernesto Bertarelli, the Italian-Swiss billionaire heir to the Serono pharmaceutical empire, married Kirsty Roper in 2000. Kirsty had been crowned Miss United Kingdom in 1988 and later co-wrote 'Black Coffee,' a worldwide hit recorded by the pop group All Saints. Ernesto had sold his family's pharmaceutical company, Serono, to Merck KGaA for $13.3 billion in 2007, cementing the Bertarelli family as one of Europe's wealthiest dynasties with a combined fortune estimated at $12 billion.
The couple lived a life of extraordinary luxury between their homes in Gstaad, Geneva, and London, and aboard their 96-meter superyacht, Vava II. Ernesto was also a passionate sailing competitor, winning the America's Cup in 2003 with Team Alinghi. They had three children together and were fixtures of the European social scene for two decades.
In the summer of 2021, the Bertarellis announced their separation by mutual agreement. Unlike many billionaire divorces, their split was described as amicable by all accounts. Kirsty received a settlement of approximately £350 million ($476 million), along with a £52 million mansion near Lake Geneva and an £8 million chalet in Gstaad. The settlement made her Britain's wealthiest divorcee.
The Bertarelli divorce is notable for what it lacked: public acrimony, contested hearings, and drawn-out litigation. Both parties appeared to prioritize their children's well-being and their own privacy. By 2023, Kirsty had publicly introduced a new partner, signaling that both parties had moved forward. The case stands as a model for how ultra-wealthy couples can dissolve a marriage with dignity when both parties are committed to a fair outcome.
Legal Breakdown: Swiss Divorce, British Assets, and Jurisdictional Strategy
Jurisdictional Considerations
The Bertarellis maintained residences across Switzerland and the UK. The choice of jurisdiction for a divorce can dramatically affect the outcome. Switzerland generally takes a more conservative approach to spousal maintenance and asset division than England, which is often considered the 'divorce capital of the world' for its generous treatment of non-earning spouses. The specific jurisdiction chosen was not publicly disclosed, but it likely played a significant role in shaping the settlement.
Valuing a Diversified Family Fortune
Unlike divorces involving a single public company, the Bertarelli fortune was spread across private equity, real estate, venture capital, superyachts, and other alternative assets. Valuing such a diversified portfolio requires multiple specialized appraisers and can be subject to significant disagreement. The amicable nature of the divorce suggests both parties agreed on valuations without resorting to adversarial expert testimony.
Protecting Children in Public Divorces
The Bertarellis' decision to announce their split jointly and avoid public litigation reflects a growing trend among wealthy couples to shield their children from the media circus that often surrounds high-profile divorces. In many jurisdictions, courts can seal certain proceedings involving children, and attorneys increasingly advise clients to negotiate privately rather than air disputes in open court.
