Although professional liability insurance is a type of business coverage, not everyone may need it.âBusinesses that need this type of insurance coverage â¦ provide professional services to customers," Capell says. This list includes accountants, architects, engineers, lawyers, consultants, counselors, insurance brokers, financial advisers, and real estate agents. Creative professionalsâsuch as writers, graphic designers, and photographersâmay want to consider it as well.Chris Michaels, founder of the blog Frugal Reality, and whose family has owned an insurance agency for more than 30 years, explains things a little differently. âBroadly speaking, anyone who holds themselves out to be an 'expert' in some activity, or who has special training â¦ anyone holding themselves to have unique or special knowledge in certain areas, or [who] is in an activity of almost any sort that may cause bodily injury, property damage, or financial loss should consider purchasing professional liability [insurance]," he says. Michaels suggests professional liability coverage should be in addition to general liability insurance.
