Judge Consolidates Situsamc Class Actions After November Data Breach

A federal judge in New York has consolidated multiple lawsuits stemming from a data breach at SitusAMC Holdings Corp. in November 2025, combining a newly filed case with an existing class-action suit to streamline proceedings.

On Wednesday, Judge Lewis J. Liman of the U.S. District Court for the Southern District of New York granted an unopposed motion to consolidate the eight separate complaints into one, citing judicial efficiency and the need to avoid duplicative discovery and inconsistent rulings.

SitusAMC stated that on Nov. 12, 2025, it became aware of an incident that compromised information stored in its systems, including accounting records and client legal agreements, which may also have affected data belonging to its clients’ customers.

“The scope, nature and extent of such impact remains under investigation by the Company and its third-party advisors,” the company wrote in a statement on Nov. 22. “The incident is now contained and our services are fully operational. No encrypting malware was involved.”

SitusAMC, which provides mortgage industry services spanning loan fulfillment, warehouse administration and securities valuation, notified customers JPMorgan Chase, Citi and Morgan Stanley of the incident, The New York Times reported.

Just two days after SitusAMC released its statement, plaintiff Armen Kelechian brought a complaint against the company. The case is now known as the lead case.

Kelechian, a customer of JPMorgan Chase, alleged that SitusAMC “failed to adequately protect Plaintiff’s and Class Members’ Private Information.” He said the unencrypted and unredacted data was compromised due to the defendant’s “negligent and/or careless acts and omissions” and its “utter failure to protect Plaintiff’s and Class Members’ sensitive data.”

The other plaintiffs with near-identical allegations included in the consolidation include Tamica Thomas, Steven Stack, Stacie Phillips, Timothy Le, Marsha Clarke, Judith Lewis and Deidre Dunham. All except Dunham claim they are customers of JPMorgan Chase.

JPMorgan did not return HousingWire‘s requests for comment. SitusAMC said that, given the ongoing litigation, it cannot provide further comment.

A company spokesperson said, “SitusAMC remains focused on working closely with clients as we continue to review the data. We will be communicating directly with clients as we determine the exact nature of the data belonging to them that was affected.”
