WWL says

Jim Walden is well known internationally for his excellent work defending individuals in complex internal and regulatory investigations.


Jim Walden, managing partner of Walden Macht & Haran LLP, is a veteran litigator who has served clients in high-profile and complex matters throughout his private-practice career. In criminal, civil and regulatory matters, Jim has established an enviable record of success by consistently developing thoughtful, multi-tiered strategies to advance his clients’ goals.

Jim has led more than 20 complex internal investigations, helping corporate clients avoid or mitigate financial penalties and address compliance failures. This includes high-stakes international matters involving allegations of cartel activity or bribery. His cross-border internal investigations include work in Brazil, China, England, France, Germany, Italy, Japan, Mexico, Poland, South Africa and South Korea. Jim has conducted investigations for global financial services firms, broker-dealers, retail banks, credit card companies, big box retailers, technology companies, and several industrial manufacturers, and continues to serve as global coordinating counsel for one of the world’s largest car companies.

In addition to his corporate work, Jim has also represented many executives and private individuals in federal, state and local criminal matters. His extensive client roster includes CEOs, CFOs, COOs and general counsel, as well as members of law enforcement, civil servants, celebrities, professional athletes, and high net worth individuals. He has also served as lead counsel in many important civil cases involving fraud, land-use and zoning, 1983 actions, contract disputes, whistleblower claims, employment litigation, historic preservation matters, and disputes over joint-ventures, partnerships and other investment structures.

Prior to launching Walden Macht & Haran, Jim was a partner with Gibson Dunn & Crutcher for nine years, where he co-chaired the firm's white-collar defence and investigations practice group and was a member of the crisis management and antitrust practice groups. He served on the firm-wide pro bono committee and was the New York chairman for pro bono legal services. As a result of his work, the National Legal Aid & Defender Association honoured the firm with the 2012 Beacon of Justice Award.

From 1993 to 2002, Jim served as an assistant US attorney in the Eastern District of New York, where he successfully tried more than 20 felony cases, including complex racketeering trials. During his time at the Department of Justice, Jim won numerous commendations, including the “Director’s Award for Superior Performance as an Assistant US Attorney” and the Federal Law Enforcement Foundation’s “Prosecutor of the Year” award. Among his many multi-agency initiatives, Jim’s work led to the first effective assault against the Bonanno crime family, one of the Five Families that dominated mid-to-late 20th century organised crime activities in New York City. For his work, The New York Times called Jim “a prosecutor even the mobsters respect” and “one of a handful of lawyers that Team Government counts on to go toe-to-toe with the [highest-priced] guys and win.”

Since its launch in February 2015, Walden Macht & Haran has grown from six to more than 40 attorneys and staff, and boasts blue-chip, global clientele. 

Jim has been recognised as a leading lawyer by Lawdragon 500 and Best Lawyers in America for his work in criminal defence: white-collar. Earlier in his career, Jim served as a law clerk for the Honorable Anthony J Scirica, US Judge, Court of Appeals, Third Circuit. He is a magna cum laude graduate of Temple University School of Law, where he served as a law review editor and received the Israel Packel Memorial Award for the highest GPA in his graduating class.
