Overview
- John Overdeck resumed testimony in Newark Family Court on Wednesday to argue that Two Sigma existed before his 2002 marriage and should not be treated as marital property.
- Judge Bruce Buechler has barred Laura Overdeck from taking the stand or calling expert witnesses after finding she hacked her husband’s email, which sharply limits her ability to present financial evidence.
- Under cross-examination Overdeck conceded that Two Sigma’s assets under management have grown since the couple filed for divorce, a fact that challenged claims the litigation hurt the firm.
- Laura Overdeck is seeking a 35% stake estimated at about $6.2 billion and has declined settlement offers above $600 million, leaving ownership and possible shifts in firm governance between Overdeck and co-founder David Siegel unresolved.
- Court records and public materials now include Millburn police bodycam footage and a 2024 defamation suit by a fencing coach linked to the parties, adding reputational detail to the trial though not directly resolving the ownership dispute.
