Laura Overdeck, estranged wife of billionaire hedge-fund manager John Overdeck, was accused in a now-dismissed lawsuit of telling others that their son’s fencing coach, Lauren Phillips, was John’s lover and responsible for the couple’s separation. The allegations have resurfaced amid the Overdecks’ high-value divorce case, drawing attention to the personal disputes surrounding what is described as New Jersey’s largest contested divorce.

Phillips alleged that Laura Overdeck’s comments harmed her reputation and fencing academy, including claims that she threatened people with real knives; the lawsuit was later dismissed after Phillips did not pursue the legal process. Laura Overdeck is seeking a share of John Overdeck’s Two Sigma interest valued by her lawyers at up to $6.2 billion, having rejected a settlement offer of about $633 million; Forbes estimates John’s wealth at around $8 billion.
