Top Advisor Barbara Guggenheim Sued for Sleeping with Clients

Allegations Surface Against Prominent Art Advisor in Lawsuit

A court case has revealed serious accusations against Barbara Guggenheim, a notable art advisor who has worked with major celebrities. The lawsuit portrays her as an unethical and manipulative figure involved in multiple misconducts, including sleeping with clients and dealers, accepting kickbacks, and coercing a former partner into compromising situations to facilitate art deals.

The plaintiff, Abigail Asher, who collaborated with Guggenheim for nearly four decades, alleges that Guggenheim repeatedly exploited her, used threats, and engaged in controlling behavior. Asher claims Guggenheim even attempted to leverage her former husband’s influence—attorney Bert Fields, known for representing celebrities like Tom Cruise and Michael Jackson—to threaten her.

In 2023, the partnership shifted from shared profits to individual earnings, which Asher asserts caused Guggenheim’s financial stability to deteriorate sharply. Asher also criticizes Guggenheim for charging exorbitant expenses to their company, including luxury spa trips, hunting safaris, and lavish parties, amounting to hundreds of thousands of dollars.

The lawsuit accuses Guggenheim of erratic behavior, including sending confusing emails that signal possible mental decline, negatively impacting professional and personal relationships. Furthermore, Guggenheim responded with a countersuit in 2024, claiming Asher misappropriated over $20 million and secretly started a competing business.

Guggenheim’s legal representative dismisses the allegations as “libelous nonsense,” questioning why Asher would have tolerated her for so many years if accusations were true. Asher emphasizes her surprise at the extent of Guggenheim’s misconduct, which she claims she only discovered while preparing the lawsuit.

The legal battle continues as both parties seek damages, with Asher’s suit requesting compensation for alleged damages, and Guggenheim seeking over $20 million in her counterclaim.
