LONDON--The estranged wife of hedge-fund tycoon Christopher Hohn will receive $530 million in what is believed to be the U.K.'s biggest-ever divorce payout, a U.K. court has ruled.

A judge in London's High Court has awarded Jamie Cooper-Hohn $493 million in cash and the rest in the form of a property in Connecticut and adjustments to her share of a pension.

A full judgment will be published in December, but the figures were cited during a court hearing on Thursday.

Ms. Cooper-Hohn, 49, was seeking half of Mr. Hohn's assets, while her husband says she was entitled to a quarter. A spokeswoman for The Children's Investment Fund Management, Mr. Hohn's firm, didn't immediately respond to a request for comment.

TCI has been one of Europe's top performing hedge funds in recent years, gaining 47% last year and 29% in 2012, according to a hedge-fund investor with access to performance figures. TCI manages around $12 billion in assets and is known for taking an activist approach to investments in companies such as Japan Tobacco Inc., Lloyds Banking Group PLC and European Aeronautic Defence & Space Co., now called Airbus Group.

Mr. Hohn and Ms. Cooper-Hohn met while students at Harvard University, and have been married for 17 years. They have four children.

In 2011, Galina Besharova, the wife of the late Russian oligarch Boris Berezovsky, received a settlement in a London divorce case that news reports put at around GBP200 million ($314 million).
