Julianna Margulies LawsuitJulianna Margulies’ former management company sued The Good Wife actress today over fees it says she owes in commissions. D/F Management claims Margulies owes them $420,000. As outlined in the complaint (read it here) filed today in LA Superior Court, the money comes from fees D/F say are owed from her Emmy-winning gig on the CBS show as well as a spokesperson contract with L’Oreal. The management company, who based its sum on a 10% commission fee, also wants the court to ensure that Margulies continues to pay them from all fees and contingent compensation from the show and the cosmetics contract in the future.

D/F signed the former ER star in February 2009. The Good Wife, in which Margulies plays lead character Alicia Florrick, debuted September 22, 2009. Margulies ended her relationship with D/F Management in late April 2011. In the filing, D/F, which was founded by Margulies’ former ICM agent Steve Dontanville and talent manager Frank Frattaroli, provide edited emails about how pleased the actress says she was with the way they handled her career. The suit also contains quotes from Margulies about wanting to cut costs.

Under standards and practices of client contracts, agencies and managers are entitled to continue to receive commissions on work they have procured for a client, even after the client has left them. Consequently, such suits as the one filed against Margulies are not uncommon in Hollywood. In April, ICM filed a civil complaint against Jersey Shore’s Pauly D for the salary raises the agency negotiated for the reality star when he was a client. D/F is also seeking costs, interest on the amount owed and “such relief as the Court deems just and proper.” D/F, which is asking for a four-day jury trial to settle the matter, is represented by Matthew Rosengart of LA firm Greenberg Traurig.
