Mary Louise Charlotte Backstrom v Martin Carl Simon Wennberg

28 April 2023
[2023] EWFC 79
Family Court
A wealthy wife and her husband divorced. The husband didn't cooperate, so the judge mostly followed their pre-nuptial agreement, giving the husband money for housing and a bit of extra cash to help him get back on his feet, but not half of the wife's fortune.

Key Facts

  • Final hearing of cross-applications for financial remedies orders between Mary Louise Backstrom (Wife) and Martin Wennberg (Husband).
  • Parties entered into multiple marital agreements (Swedish cohabitation agreement, agreement disapplying community of property, English pre-nuptial agreement, and English post-nuptial agreement).
  • Wife's assets: £250 million.
  • Husband's assets undisclosed; Wife estimates at least £2.5 million based on available information.
  • Husband failed to provide financial disclosure and comply with court orders, resulting in findings of contempt of court.
  • Husband did not attend the final hearing.
  • Wife's open offer included £6.5 million housing fund, £50,000 annual child maintenance.
  • Husband's open offer sought 50% of Property B (£42.5 million), £30,000 monthly child maintenance, and £20,000 monthly spousal maintenance.
