The civil racketeering suit filed against hedge fund billionaire Steven Cohen by his ex-wife Patricia Cohen (née Finke) has taken another turn, with Finke’s former lawyer — who sought to withdraw the suit after being replaced as counsel — suing his erstwhile client and her new lawyer for unpaid legal fees.

Bloomberg reports that Paul Batista filed the civil complaint against Finke and Gaytri Kachroo of Boston’s Kachroo Legal Services in state court in New York on Thursday. In his complaint, Batista asks that a lien be placed on any potential settlement Finke wins against her former husband, whom she divorced in 1988. Batista also demands that he be reimbursed for expenses he racked up on Finke’s behalf in the seven months he spent preparing her suit against Cohen.
