The former CEO of  Patriot National is suing Simpson Thacher & Bartlett and Kasowitz Benson Torres for malpractice in Florida state court, alleging the law firms are to blame for the company’s demise and impending bankruptcy.

Fort Lauderdale-based Patriot National, an outsourcing, technology and underwriting company for the insurance industry, laid off 250 employees last month and announced that it would be acquired by its lenders, and that its subsidiaries would file for Chapter 11 bankruptcy.
