A matrimonial attorney and her firm are facing a malpractice suit in state Superior Court in Morris County, New Jersey, after litigation over a divorce was disrupted by a data breach.

The complaint said attorney Erin Brueche, who represented Shaun Kennedy in a matrimonial case, sent an email to opposing counsel about a routine scheduling matter on Sept. 12, 2017. But “negligently and without care,” Brueche’s message included a password and related information allowing any recipient to access electronic files that were stored by her firm, the Weinberger Divorce and Family Law Group of Parsippany, New Jersey. The exposed information related to the representation of Kennedy.
