Pre Nuptial agreement upheld by Court of Appeal
Katrin Radmacher, a German heiress, has overturned an earlier decision which awarded her ex-husband £5.8m of her £100m fortune despite their agreement.
Frenchman Nicolas Granatino had agreed not to make a claim if they divorced.
Such contracts are enforceable in France and Germany, but not in the UK where the couple married in 1998.
Miss Radmacher, 39, is one of Germany’s richest women and Mr Granatino is a former investment banker.
Their pre-nuptial was signed in Germany before the couple married.
The pair’s marriage was said to have broken down after Mr Granatino, 37, gave up a lucrative job in the emerging markets sector in 2003 to become a £30,000-a-year biotechnology researcher at Oxford University.
They divorced in 2006 and a High Court ruling last year awarded her ex-husband £5.8m.
Miss Radmacher appealed against that decision and her lawyer, Richard Todd QC, told a panel of three Court of Appeal judges the freedom to agree a contract was “at the heart of all modern commercial and legal systems”.
