If an incident occurs involving personnel from an unlicensed company, you can face negligent-hiring liability. Unlicensed operators also frequently lack certified training, guard registration (guard cards) and active liability insurance, and states can fine businesses that knowingly use them. Always verify the state license before signing a contract.
