The wife of a London hedge fund manager has been granted £337 million ($530 million) in their divorce settlement, the largest sum ever awarded by a British court, the Guardian reported.

American Jamie Cooper-Hohn announced her intention to divorce husband Sir Chris Hohn in March 2012, and the two have been locked in legal battles ever since.

The couple established the UK’s Children’s Investment Fund Foundation in 2002 and are considered great philanthropists. But while Cooper-Hohn maintained during proceedings that she had made a central contribution to the foundation, her husband claimed he was the sole decision maker in the CIFF and the family’s “key” money-maker.

Hohn’s lawyers said his personal wealth was £64.3 million, while his wife’s legal team said it was £890 million. Hohn’s The Children’s Investment Fund Management hedge fund controls investments worth around $8 billion.

Cooper-Hohn, who the New York Daily News reported is Jewish, met her husband at Harvard. The two married in 1995 and have four children together.

The CIFF holds more than $4.3 billion, and pledged more than £500 million last year for fight child malnutrition.

The previous largest divorce payout was between £100 million- £200 million, to Galina Bershova, ex-wife of Russian oligarch Boris Berezovsky, according to the Guardian.
