The Court of Appeal has seemingly turned the law on pre-nuptial agreements on its head in a landmark ruling this week.

The Court ruled that the husband of a German heiress should receive only about £1 million from her estimated £100 million fortune after their divorce, because he had signed a ‘pre-nup’ to waive any rights to her wealth should they divorce. He will also have approximately £700,000 in debts paid off and will have a house provided until the couple’s daughter reaches the age of 22.

The lower court had awarded him £5.6 million. The couple married in 1998 and the marriage broke down when the husband left his job as an investment banker to become a university researcher.

An appeal is likely.
