Errors and Omissions Liability Coverage/Professional Liability Insurance – If you provide any type of advice, expertise or professional service, you risk being sued by a customer, client or other party who claims he or she was injured due to your negligent act, error or omission. This type of negligence is sometimes referred to as “malpractice.” Professional Liability Insurance, also called Errors and Omissions Liability Insurance, pays the cost of your defense and any damages awarded, up to policy limits. Insurance companies have developed many specialized policy forms that respond to the individual risks characteristic of particular professions and services. 

Professionals that operate their own businesses need professional liability insurance in addition to an in-home business or businessowners policy. This protects them against financial losses from lawsuits filed against them by their clients.

Professionals are expected to have extensive technical knowledge or training in their particular area of expertise. They are also expected to perform the services for which they were hired, according to the standards of conduct in their profession. If they fail to use the degree of skill expected of them, they can be held responsible in a court of law for any harm they cause to another person or business. When liability is limited to acts of negligence, professional liability insurance may be called "errors and omissions" liability.

Professional liability insurance is a specialty coverage. Professional liability coverage is not provided under homeowners endorsements, in-home business policies or businessowners policies (BOPs).

Small Business Insurance Basics

Insurers often combine a number of insurance coverages into a package that is sold as a single contract. The most common policy for small businesses is the Businessowners Policy (BOP).

The BOP combines coverage for all major property and liability insurance risks as well as many additional coverages into one package policy suitable for most small businesses. The term “BOP” specifically refers to insurance policy language developed (and revised as needed) by experts at ISO. ISO provides sample insurance policy language, research and a variety of other products to insurance companies.

The BOP includes business income insurance, sometimes called business interruption insurance. This compensates a business owner for income lost following a disaster. Disasters typically disrupt operations and may force a business to vacate its premises. Business income insurance also covers the extra expense that may be incurred if a business must operate out of a temporary location.
