Diane Rosemin-Culligan, the former chair of the London City Lionesses, must sell her nine-bedroom mansion in London's Primrose Hill to satisfy a divorce settlement with her ex-husband, Anthony Culligan, a Bitcoin millionaire. The decision comes after the Court of Appeal overturned a previous ruling that had awarded her the house.
Mr. Culligan, a computer programmer turned cryptocurrency entrepreneur, reportedly turned an initial £10,000 Bitcoin investment into £20 million over five years. The couple, who were married for approximately 40 years and have three children, accumulated a joint net worth of £27 million. Their assets were ordered to be divided equally.
Initially, Ms. Rosemin-Culligan was awarded the Primrose Hill house in March 2025. However, Mr. Culligan appealed, arguing the previous division of assets was unfairly weighted against him. His share was primarily dependent on the value of shares in Colendi Holdings Limited, a company he was involved with.
The Court of Appeal, led by Lord Justice Moylan, found that the previous judge's reasoning for placing greater risk on Mr. Culligan—based on his not informing his then-wife about the sale of another company, SETL Limited—was not relevant. The court determined that the sale of SETL would have occurred regardless of consultation due to the company running out of money.
To rebalance the settlement, the judges ordered that the value of the Colendi shares be split equally. This adjustment requires Ms. Rosemin-Culligan to sell the £7 million mansion and transfer 40.4% of the proceeds to Mr. Culligan.
The couple met in 1982 and began living together in 1985, marrying in Japan in 1992. While there is a dispute over the exact end date of their relationship—Mr. Culligan citing September 2020 and Ms. Rosemin-Culligan suggesting April 2022—their wealth was accrued during their marriage. A significant portion of their fortune stemmed from Mr. Culligan's Bitcoin investment, which grew substantially between 2012 and 2017. This wealth funded their businesses, living expenses, a £2.1 million renovation of their Primrose Hill home, and the purchase of a property in the US for Mr. Culligan.
Ms. Rosemin-Culligan founded the London City Lionesses after the women's team separated from Millwall FC. She served as the team's chair until she sold the club in 2023 to a U.S. businesswoman, reportedly after players urged her to secure new investment or ownership. She continued with the club as a consultant for four years, earning £750,000 annually. Mr. Culligan's firm, SETL, had previously sponsored the team.
The couple's split was acrimonious, with each party attributing blame. Ms. Rosemin-Culligan accused her ex-husband of leaving the marriage without explanation. Mr. Culligan cited marital tensions, including the costly house renovation and what he described as his wife's 'overbearing' and 'irrational' behavior, as reasons for the separation.
