Laura Overdeck

Laura Overdeck filed for divorce from John Overdeck in March 2022, 20 years after the couple’s marriage and 21 years after John cofounded $60 billion quant hedge fund Two Sigma in 2001 with David Siegel. The couple did not have a prenuptial agreement, and John Overdeck amassed the bulk of his estimated $7.3 billion fortune since they married, presumably setting Laura up for a hefty payout. But her lawsuit claims she found out soon thereafter that documents she signed in 2018 permitting transfers “exceeding several billion dollars” from trusts set up in New Jersey to new trusts housed in tax-friendly Wyoming came with unexpected consequences. The original New Jersey trusts had been set up to reduce federal estate and gift taxes and to benefit their three shared children and both partners. The law firm Seward & Kissel and a spokesperson for John Overdeck at Two Sigma did not respond to requests for comment. The partner named in the suit is Hume R. Steyer, identified on Seward & Kissel’s website as co-head of its Private Clients/Trust and Estates Group.
