Police were called to the New Jersey mansion of hedge fund co-founder John Overdeck at least eight times over a period of more than a year, according to reports. These incidents occurred while Overdeck is engaged in what is reportedly the most expensive divorce case in the state's history, seeking to divide his estimated $6.2 billion stake in the firm Two Sigma.

The calls to the 6,000-square-foot estate in Short Hills, New Jersey, reportedly involved an unnamed woman whom Overdeck identified to police as someone he was seeing. The incidents took place between April 2023 and June 2024, with no charges filed in any of the instances, according to Bloomberg, which cited police reports and bodycam footage.

One call in October 2023 involved a dispute inside the mansion, which Overdeck and his estranged wife, Laura Overdeck, purchased two decades prior for $3.64 million. Body-worn camera footage reportedly captured John Overdeck describing his relationship with the woman who made the calls as "volatile."

During one of these encounters, the woman reportedly accessed a file related to Two Sigma on Overdeck's computer, and in another instance, sent an email to the firm. In a separate 2023 call, she requested a wellness check on Overdeck, who she stated had been sitting in his car for four hours. Overdeck allegedly told responding officers he was upset over a canceled trip and described his relationship with the woman as "complicated."

Laura Overdeck filed for divorce in March 2022, citing irreconcilable differences. She is seeking 35% of her husband's stake in Two Sigma, an equal share of their assets including the mansion, and restoration as an equal partner in trusts for their three children. Her initial offer from John Overdeck was reportedly over $600 million.

The divorce proceedings have been characterized by delays. At a recent court appearance, Judge Bruce Buechler admonished attorneys for not resolving disputes over evidence redactions prior to the trial, stating, "Are we using the trial time very effectively, in the court’s view? Absolutely not."

John Overdeck had previously argued that public disclosures related to the case could harm Two Sigma, claiming the firm had already lost investors. However, under cross-examination, he conceded that the assets under management at Two Sigma had increased since the divorce complaint was filed and amid media coverage.

Laura Overdeck's pleadings were dismissed earlier this year following a ruling that she violated discovery orders. This means her case can primarily be presented through her husband's cross-examination. Court findings indicated her "underhanded tactics" included accessing her estranged husband's computer and photographing emails detailing his legal strategy.
