When do businesses need professional liability insurance?

Professional liability insurance is designed for professionals who make a living off their expertise. It addresses risks unique to providing specific services, such as an engineer who misses a project deadline or an architect who makes a mistake with plans for a building.

If the client sues, this policy covers the cost of a lawsuit up to your policy limit. Clients may request a certificate of insurance as proof that you have this coverage.
