Daniel Kaplan, former name partner at the South Florida firm Rosenthal Rosenthal Rasco Kaplan, said he wishes he and his partners had prepared a written operating agreement when they formed the firm back in 2009.

Nearly four months after their Nov. 30 breakup, Kaplan filed suit against his former partners, who owned the firm's office space through a separate company of their own called Ringmasters LLC.

The suit, filed against Eduardo Rasco, Kerry Rosenthal and their associated companies, seeks judicial dissolution of the firm, more than $15,000 in damages and claims that Kaplan's partners made improper distributions and breached their duty of loyalty and care. Other court action is underway with his partners as plaintiffs, but that complaint is under seal, lawyers said.
