General liability policies shouldn’t be confused with professional liability policies. Professional liability policies normally provide coverage for mistakes related to a professional’s work. For example, a policy might cover a mathematical error than an accountant makes or poor advice that an investment advisor offers. These policies usually don’t offer bodily injury, property damage, or false advertising liability coverage, though. Therefore, most professionals should have a general liability policy in addition to any professional liability insurance they carry. The coverages that a general liability provides offer complementary, rather than overlapping, protection.
