Mary-Kate Olsen & Olivier Sarkozy: The Ironclad Prenup That Saved a $250 Million Fortune
Her lawyers called it 'ironclad' — and it was
Key Facts
What Happened
Mary-Kate Olsen and French banker Olivier Sarkozy — half-brother of former French President Nicolas Sarkozy — married in November 2015 in a private Manhattan ceremony. The 17-year age gap (Olsen was 29, Sarkozy was 46) and cultural differences drew immediate media attention. Olsen, who with twin sister Ashley had built a fashion empire worth an estimated $250 million through The Row and Elizabeth and James brands, entered the marriage with a prenuptial agreement her lawyers described as 'ironclad.'
The marriage lasted less than five years. In May 2020, at the height of the COVID-19 pandemic, Olsen filed an emergency petition for divorce after learning that Sarkozy had terminated the lease on their New York City apartment. She alleged that Sarkozy was pressuring her to move out during the lockdown, and sought an emergency divorce filing — which was denied because New York courts had suspended non-emergency proceedings during the pandemic.
The divorce was eventually filed through standard channels and finalized in January 2021. The prenup proved decisive. Olsen's fashion business interests, personal fortune, and future earnings were entirely protected. Sources indicated there was 'no bad blood' between the parties once the legal proceedings concluded, though the pandemic-related emergency filing had created brief tension.
The case became a case study in prenuptial agreement drafting for business owners. Olsen's lawyers had structured the prenup to protect not just her existing wealth but her business interests, intellectual property, brand equity, and future earnings from The Row — a brand that would grow significantly in value after the marriage. The Sarkozy divorce proved that a well-drafted prenup can provide total protection even in a major New York divorce.
Legal Breakdown: Prenups and Protecting Business Empires
Protecting Business Interests in Prenups
Olsen's prenup specifically carved out her fashion brands, intellectual property, and future business earnings as separate property. This is critical for entrepreneurs — without such provisions, a spouse could claim that business growth during the marriage constitutes marital property subject to division.
Emergency Divorce Filings
Olsen's attempt to file an emergency divorce petition during COVID was denied because New York had suspended non-emergency court operations. This highlighted the limitations of emergency filings — courts generally reserve emergency jurisdiction for cases involving domestic violence, child endangerment, or asset dissipation, not lease disputes.
New York Divorce for High-Net-Worth Individuals
New York is an equitable distribution state, meaning assets are divided fairly but not necessarily equally. Without a prenup, Olsen's business empire could have been subject to division based on the growth in value during the marriage. The prenup eliminated this risk entirely by defining the business as separate property.
What This Means for Your Divorce
- →If you own a business, your prenup must specifically address business interests, intellectual property, and future growth — not just current assets.
- →Emergency divorce filings have strict requirements and may be denied if the situation does not meet the legal threshold for emergency relief.
- →An 'ironclad' prenup means one that has been drafted by experienced attorneys, signed voluntarily, and based on full financial disclosure.
- →Even with a strong prenup, the divorce process still takes time — Olsen's case took over eight months from filing to finalization.
