Laura Overdeck, the estranged wife of billionaire hedge fund manager John Overdeck, has returned to court in Newark after rejecting a settlement offer worth more than $600 million in what is believed to be New Jersey's largest divorce case.
The 56-year-old math enthusiast appeared before family court Judge Bruce Buechler as she seeks an even bigger slice of the fortune her husband built through his investment firm, Two Sigma. She had previously warned him that a $633 million settlement offer was not enough.
Laura is seeking 35 percent of the value of John's stake in the Manhattan-based hedge fund, which he co-founded in 2001, a year before the couple married without a prenuptial agreement. The two sides hold sharply different valuations of his stake, with John's attorneys placing it at $4.5 billion and Laura's legal team valuing it at $6.2 billion, arguing that it constitutes a marital asset.
Her legal action comes after months of intense dispute, during which she claimed John had "schemed" to leave her with as little as possible. Her lawyers previously asserted that he had "methodically and strategically" attempted over several decades to secure his wealth in anticipation of a split, intentionally hiding assets and planning his escape during their marriage.
On Tuesday, the couple attended proceedings in a Newark courtroom to address the financial valuation of Two Sigma's assets, with the overall firm valued at $80 billion, according to reports by The New York Post.
Closed Doors and Trade Secrets
John requested that Judge Buechler clear the courtroom to preserve the confidentiality of Two Sigma's financial operations during detailed testimony from his financial expert, Todd Povlich. The judge granted the request for portions of the testimony.
While Judge Buechler declined to seal the entire proceeding, he determined that specific testimony detailing protected company secrets should be heard behind closed doors. He expressed concern that Povlich would discuss where company values are heading, what assets are being evaluated, and where investments are directed.
Laura's attorneys questioned the necessity of keeping the testimony private, noting that John's legal team had already made its company valuation public. During the sealed session, Povlich was expected to explain how he arrived at his valuation of Two Sigma and detail how each of the firm's 20 separate entities was assessed.
The proceeding marked the 10th day of a multiday hearing over the hedge fund, which is also the subject of a bitter internal power struggle between John and his co-founder, businessman David Siegel. Povlich served as John's second-to-last witness in the hearing.
Courtroom Demeanor and Hacking Allegations
During Tuesday's public proceedings, Laura appeared highly engaged. Wearing red sunglasses and metallic woven leather heeled mules, she typed on her laptop and regularly leaned over to consult with her attorneys.
In contrast, John appeared largely detached, spending significant periods looking down at his mobile phone while his attorney conducted questioning.
Although John had testified over several days earlier in the proceedings, Judge Buechler barred Laura from taking the witness stand following accusations of misconduct. The judge stated that she allegedly hacked into John's computer, broke into his post office box, and deleted evidence from her mobile device.
The courtroom proceedings are scheduled to resume in public on Wednesday morning. The couple is set to return to court later this month to hear further testimony from an additional financial expert.
A Two-Decade Marriage and Asset Battles
Laura filed for divorce in 2022, bringing an end to the couple's 20-year marriage. Both trained in mathematics, the pair raised three children together at their estate in Short Hills, New Jersey, supported by a full-time nanny and a housekeeper working 15 hours a week.
The contested divorce went to trial in August before Superior Court Judge Buechler, with Bloomberg reporting from the courtroom on the historic proceedings. In August, John's lawyers stated that their client, who holds an estimated net worth of $8 billion, offered his ex-wife $723 million in tax-free cash, but Laura insisted she is entitled to a far larger sum through a share of his fund.
John's legal team argued that Two Sigma does not represent a marital asset because it was established in 2001, two years before the couple married in 2002. His lawyer, Jonathan Wolfe, stated that the company had completed substantial work and managed hundreds of millions of dollars prior to the wedding.
Wolfe noted that John earned $685 million during the marriage, all of which was deposited into a joint bank account, while stressing that John had already built billions in wealth before marrying. Wolfe argued that the financial offer was more than sufficient to support the marital lifestyle the couple had established.
Clashing Claims and Multi-Million Dollar Assets
Laura's attorney, Therese Lyons, countered that Two Sigma was merely a concept when founded and did not begin active trading until after the marriage. John testified that he expanded the firm from under $1 billion to $80 billion over the past 25 years.
Lyons doubled down on allegations against John, claiming he worked tirelessly to hide assets and schemed to strip billions from the marital estate. She told the court that John Overdeck is not a man who woke up one morning and decided to divorce his wife.
Beyond the hedge fund stake, Laura is seeking hundreds of millions of dollars in Treasury bonds held within a trust, alongside equal managerial control over the couple's family foundation. A 2024 tax filing reviewed by Bloomberg showed that the foundation held $920 million in assets. If she is denied joint control, her legal team requested that John be required to transfer 50 percent of its value to a charity of her choice.
Prior to co-founding Two Sigma, John worked at investment firm DE Shaw & Co, where he assisted Jeff Bezos during the early launch of Amazon. He recently purchased a waterfront mansion in Palm Beach, Florida, for $72 million, where he currently resides with his girlfriend, Kimia Shadrokh, 42, a managing director at Peakstone and former commercial real estate executive at Moinian Group.
Laura studied astrophysics at Princeton University before earning a Master of Business Administration from the Wharton School of Business. She subsequently founded and continues to direct Bedtime Math, an educational non-profit organization designed to help parents teach mathematics to children.
