Miami woman sought at least $35 million from Northern Trust over alleged mishandling of her $20 million family trust

Elizabeth Madden, who was 81 when she filed her lawsuit in January 2026, alleges that Northern Trust failed to protect her family’s roughly $20 million legacy trust from unauthorised transactions by a former employee. Her complaint says Christopher Walters, a former vice president and senior fiduciary relationship adviser at the bank, used money from the account to pay credit-card debts and expenses associated with a fitness gym he operated. Madden is seeking at least $35 million in damages from Northern Trust, accusing the bank of failing to prevent the alleged misconduct. Walters is not a defendant in her lawsuit against the bank, but he faces separate civil proceedings brought by Northern Trust and federal criminal charges. He pleaded not guilty in July 2026 to eight counts of bank fraud and one count of aggravated identity theft. Northern Trust has said it was also a victim of Walters’ alleged conduct and disputes Madden’s claims about its responsibility.Lawsuit alleges unauthorised transfers from a family trustMadden’s family had a longstanding relationship with Northern Trust. Her grandfather founded Security Trust Company, a Miami bank acquired by Northern Trust in 1971. The family’s connection to the institution helps explain why Madden continued to entrust her assets to it for decades, according to published reporting. Madden filed her lawsuit against The Northern Trust Company on January 28, 2026, in the US District Court for the Southern District of Florida. The complaint identifies Walters as a former vice president and senior fiduciary relationship adviser who worked at Northern Trust from 2000 to 2024. According to the complaint, Walters transferred money from Madden’s trust without authorisation and directed payments towards credit-card accounts under his control. The alleged transactions continued over more than a decade. The lawsuit accuses Northern Trust of failing to maintain adequate safeguards over trust payments and alleges that the bank collected more than $1 million in fees while the misconduct continued.Madden’s lawyers at Carlton Fields describe the case as an elder financial abuse claim involving alleged unauthorised transfers from a legacy trust. The firm’s announcement of the lawsuit identifies the damages sought as at least $35 million. Northern Trust disputes Madden’s account of its role. The bank has maintained that it was a victim of Walters’ alleged fraud, arguing that an employer cannot be expected to be immune to dishonest employees. Madden’s lawyer, Lee Stapleton, told the Miami Herald that Northern Trust had provided at least three different estimates of the amount allegedly taken. The competing positions remain part of the civil dispute, rather than established findings that Northern Trust itself stole money from Madden.Alleged misconduct surfaced after a change of banksMadden transferred her account to Grove Bank & Trust in Miami in early 2025. According to reporting by the Miami Herald, the alleged misconduct came to light in connection with the transition. The timing of the discovery has also been discussed by Madden’s lawyer, so it should not be treated as an independently established finding about when Northern Trust first learned of the alleged transactions. Walters was terminated in autumn 2024. Northern Trust subsequently filed its own civil lawsuit against him in federal court in August 2025. That case, The Northern Trust Company v. Walters, is separate from Madden’s lawsuit against the bank.In its case against Walters, Northern Trust referred to the affected client as a “Client-Victim” rather than naming Madden. The bank alleged that Walters repeatedly lied to a client while acting outside his authority and abusing his position. The case proceeded after Walters failed to respond. The court docket records a clerk’s entry of default on December 29, 2025, followed by a final default judgment in Northern Trust’s favour. Published reporting states that a federal judge entered the judgment in February 2026, awarding the bank $75,001. A default judgment can be entered when a defendant fails to respond to a lawsuit. The judgment in Northern Trust’s case against Walters does not resolve Madden’s separate claims against the bank or establish that Northern Trust is liable for her alleged losses.Court rejects Northern Trust’s motion to dismissNorthern Trust filed a motion seeking dismissal of Madden’s complaint in February 2026, arguing that it should not be held liable for the alleged scheme. The motion was described in legal reporting as a request to dismiss certain claims, rather than an attempt to end the entire case. On July 13, 2026, the court heard oral arguments on the motion. In an order entered on July 14, Judge Jacqueline Becerra denied Northern Trust’s motion to dismiss. The order also addressed discovery disputes, granting Madden’s request to compel the deposition of a Northern Trust employee and setting deadlines for further discovery. The ruling allowed Madden’s claims to continue, but it did not establish that her allegations were true.The court had earlier granted part of Madden’s request to expedite the trial schedule because of her age. On March 2, the judge directed the parties to confer and submit a joint scheduling report proposing an expedited schedule. That order did not itself set a specific trial date. The parties were subsequently directed to attend mediation by August 6, 2026. The publicly accessible docket information reviewed for this article does not establish the outcome of that mediation, so no settlement or failed mediation is asserted here. The latest docket entries available in the reviewed record can be checked through the federal case docket for Elizabeth Madden v. The Northern Trust Company.Former adviser pleads not guilty to federal chargesWalters’ criminal case is separate from both civil lawsuits. According to the Miami Herald and ThinkAdvisor’s July 9 report, Walters pleaded not guilty in early July 2026 to eight counts of bank fraud and one count of aggravated identity theft. Prosecutors allege that Walters falsified emails and documents submitted to Northern Trust employees to generate fraudulent checks and wire transfers from a client’s account. The indictment does not name Madden or Northern Trust, although media reports have linked the criminal proceedings to the allegations in Madden’s civil lawsuit.The Miami Herald reported that the alleged scheme involved approximately $3 million across about 200 transactions over roughly a decade. Walters is accused of using money from the client’s account to pay credit-card debts and rent for his fitness gym. The figures describe different aspects of the dispute: Madden’s trust was valued at roughly $20 million, the alleged theft is reported at approximately $3 million, and her lawsuit seeks at least $35 million in damages. The damages sought should not be confused with the amount allegedly taken.Walters is presumed innocent unless proven guilty in the criminal case. Madden’s allegations against Northern Trust also remain subject to the civil proceedings. The case raises questions about how financial institutions monitor advisers who manage client assets over many years. Madden’s lawsuit will examine whether Northern Trust met its responsibilities in overseeing the account and responding to the alleged transactions. The separate criminal case will address the charges against Walters, while Northern Trust’s civil action seeks to hold its former employee accountable.You use AI every day. Now get your AI Quotient.
