Every business owner should speak with a broker to see if errors and omissions insurance would be beneficial to their line of work. This protects against frivolous or malicious claims. It covers protection for work you have done, in the event a client takes legal action against you. If your business or profession gives professional advice, such as an advertising agency, a consulting firm, a doctor or advisor, you might be vulnerable to actions against you if your service or recommendation falls short of what was required.
