Katz Auto Insurance was a Baltimore Maryland area high risk auto insurance company that was closed down after an investigation found that it was participating in unethical and illegal business practices. The company was selling insurance through unlicensed brokers and an independent investigation found that money was being diverted into the personal accounts of the former owner, Hal Katz. Eventually he lost his license to sell insurance in the state of Maryland and the company was renamed to EZ Insurance. He owned three firms, and his licenses to conduct operations for those firms were revoked, with two of the firms (Interstate Auto and Insurance Payment Plan, Inc.) being liquidated.
