Miami woman accuses Northern Trust, ex-VP of stealing millions from her account

When the Chicago-based Northern Trust Company acquired her grandfather’s Miami bank in the early 1970s to gain a foothold in Florida, Elizabeth Ludwig Madden kept her $20 million inheritance with the new owner to manage the small fortune.

For decades, nothing seemed amiss about her Northern Trust account. But in the fall of 2024, Madden discovered that a Northern Trust vice president who managed her estate assets told her that he was let go without explanation. Early last year, Madden moved her account to Grove Bank & Trust in Miami and soon learned from the bank that her former Northern Trust investment adviser had been using her money to pay off his large credit card debts.

In a lawsuit filed this week in Miami federal court, Madden accused Northern Trust Bank and its former vice president, Christopher Walters, of stealing millions of dollars from her for more than a decade while she held her account with the prominent private wealth management company.

“It was a betrayal by both Christopher Walters and Northern Trust, but Northern Trust the most because I trusted them and knew them longer than Christopher Walters,” Madden, 81, told the Miami Herald. “They really let me down — it was appalling.”

Miami banking family

Madden, who now lives in Georgia, is the granddaughter of the founder of a former Miami financial institution, Security Trust Company, that Northern Trust bought in 1971. That acquisition was Northern Trust’s first foray outside of Illinois, and it has grown into the bank’s second-largest market in the United States.

Her lawsuit alleges that, as a fiduciary, Northern Trust had a legal duty to protect the assets in her trust estate by maintaining internal safeguards.

“Northern Trust did not merely fail to prevent Walters’ misconduct; it facilitated it,” the complaint alleges. “Walters orchestrated an embezzlement scheme that was extensive, relentless, and grossly predatory. The elder abuse and elder financial exploitation went on for many years.”

The 10-count suit, which seeks $35 million in damages, accuses the bank of civil exploitation of a vulnerable adult, breach of fiduciary duty, negligent supervision and negligence, along with vicarious liability for Walters’ alleged theft. Walters is not named as a defendant in the federal case, though the suit alleges that both Walters and Northern Trust are responsible for her loss.

Walters, 49, who records show once lived in a Brickell Avenue condo highrise, could not be reached on his cell phone and did not respond to a Miami Herald email seeking comment. He had worked at Northern Trust from at least 2009 to 2024.

In a statement, Northern Trust said: “Consistent with our commitment to acting in the best interest of our clients, we tendered payment to the impacted clients for the full amount of the stolen funds, plus associated lost opportunity costs. While we are disappointed by this latest legal action, we are confident in the facts of the matter and will respond through the appropriate legal channels.”

Madden’s suit accuses Walters, who is also a personal trainer, of stealing her trust assets to fund failed business ventures, including his gym in Miami, and to support his lifestyle, while he worked “under Northern Trust’s authority.”

He ingratiated himself with Madden, sending her frequent emails through his Northern Trust email account, texting her obsessively, and even visiting her at her Georgia home, the suit says.

In addition to her case, Madden’s nephew, Robert P. Ludwig III, also sued Northern Trust and Walters in Miami-Dade Circuit Court, claiming they are also liable for the alleged theft of assets from his late father’s trust estate with the bank. Northern Trust has three locations in South Florida: Miami, Coral Gables and Key Biscayne.

“Northern Trust is a misnomer,” said Madden’s attorney, Lee Stapleton, who filed both cases with lawyer Aaron Weiss, with the Carlton Fields law firm. “The bank has proven itself to be anything but trustworthy and betrayed the very fiduciary duties it claims to uphold.

‘The thefts happened under Northern Trust’s watch’

“These thefts took place over at least a 16-year period,” she said. “The thefts happened under Northern Trust’s watch, allowing Walters to steal millions while Northern Trust collected millions in fees.”

In her complaint, Madden said that when she learned of the alleged theft of funds from her account, she notified Northern Trust executives in February 2025 that they should also examine the trust estate of her older brother, Bobby Ludwig. The brother, who she said suffered from dementia and paralysis, had died in 2012 and made his only child, Robert Ludwig, the beneficiary of his estate. She said Walters had almost unfettered access to that account at Northern Trust.

Madden said that nine months later, in September, Northern Trust notified her nephew in emails that it “discovered two unauthorized transactions” from Bobby Ludwig’s trust account. Northern Trust said the “unauthorized transactions” were for $30,000 each in February and April 2009. But Northern Trust did not disclose when it discovered the thefts, she said.

In an interview, Madden said she was not only “shocked” by Walters’ betrayal, but also by Northern Trust’s legal actions after firing him in the fall of 2024.

In August, Northern Trust sued Walters in Miami federal court, alleging he “repeatedly lied to a client,” identified as a “Client-Victim,” not as Madden, while “acting outside the scope of his authority and abusing his position.”

“Walters personally stole money from the Client-Victim by accessing funds in the Client-Victim’s Northern Trust account, circumventing security safeguards and taking steps to cover and conceal his misconduct from Northern Trust,” the bank’s lawsuit alleges. “Walters is now a former employee, and Northern Trust brings this action to hold Walters accountable for his blatant fraud and breach of fiduciary duty.”

Portraying itself as a victim, Northern Trust alleges that Walters’ “conduct was outrageous and intentional.”

Northern: Making client whole, sued employee

In the suit, Northern Trust said it did an internal audit and reported Walters’ alleged theft to federal authorities, adding that it was “working to remediate the harm caused by Walters’ conduct and has communicated to the Client-Victim its commitment to make the Client-Victim whole for Walters’ theft.”

According to federal court records, Northern Trust’s lawyers were unable to serve Walters with the bank’s lawsuit and recently proceeded to seek a default judgment against the former employee, who did not have an attorney representing him.

Madden, when asked about Northern Trust’s lawsuit against Walters, said: “I think they were just trying to shift the blame — ‘Look, it was his fault.’ “

“But he had a supervisor and somebody should have known.”

Northern Trust, in its statement provided to the Herald, disagreed her assessment.

“When we learned that a former employee engaged in fraudulent transactions, we responded swiftly and appropriately,” the company said, “reporting the matter to the authorities, cooperating fully with their investigation, and retaining a prominent law firm and a forensic accounting firm to investigate the incidents. In August 2025 we initiated litigation against the former employee to hold him accountable for his wrongdoing.”
