Professional liability insurance (PLI), also known as errors and omissions (E&O) insurance, protects professionals and businesses against claims of negligence or mistakes made in their work. This coverage includes:

  • Professional Negligence: Claims from failing to meet professional standards.
  • Errors and Omissions: Mistakes or oversights in professional services.
  • Defense Costs: Legal fees and court costs for covered claims.

For example, if a financial advisor gives incorrect investment advice leading to client losses, PLI can cover the legal defense and settlements or judgments awarded to the client.

Coverage Details

Let’s go into more details on what PLI covers:

1. Professional Negligence

PLI protects against claims of failing to meet professional standards. This includes situations where a client alleges that your professional advice or services caused them financial harm due to negligence or incompetence.

Example Scenario

An architect designs a building that does not meet code requirements, leading to financial losses for the client. PLI would cover the legal defense and settlements.

2. Breach of Contract

PLI also covers claims arising from not fulfilling contractual obligations. If your business fails to deliver services as agreed in a contract, and this failure results in financial loss for your client, PLI can help cover the associated costs​.

Example Scenario

A consultant fails to deliver a project on time, causing the client to incur extra costs. The insurance would cover the claim.

3. Errors and Omissions

This insurance provides protection against mistakes or oversights in professional services. It ensures that if you make an error in your work or omit crucial information, resulting in client losses, your policy will cover the legal and settlement costs​.

Example Scenario

A financial advisor makes an error in investment advice, resulting in client losses. PLI covers the resulting legal expenses and settlements​​.

4. Defamation Claims

PLI also covers claims of libel and slander. If your business is sued for allegedly making false and damaging statements about a client, this insurance can cover the legal defense and settlements​.

Example Scenario

A marketing firm is sued by a competitor for allegedly making false and damaging statements about them in an ad campaign. The competitor claims these statements harmed their reputation and business. PLI covers the marketing firm’s legal defense costs and extra expenses, ensuring financial protection against the defamation lawsuit.

5. Defense Costs

Professional liability insurance covers defense costs, including legal fees, court costs, and settlements. This ensures that even if a claim is frivolous, your business is protected from the significant financial burden of legal expenses​.

Example Scenario

An IT consultant is sued by a client who claims their advice led to a data breach. Even though the claim is frivolous, the consultant faces significant legal expenses. PLI covers the legal fees, court costs, and extra expenses, protecting the consultant from financial burden.

PLI Exclusions

Criminal Acts

Professional liability insurance does not cover any intentional wrongdoing or fraudulent acts. This exclusion means that if a claim arises from criminal activity or intentional fraud, the insurance policy will not provide coverage for defense costs or any resulting settlements.

Employee Injuries

Claims related to employee injuries and other internal employment disputes are also not covered under professional liability insurance. These types of claims fall under workers’ compensation insurance, which specifically addresses workplace injuries and illnesses​.

Property Damage

Professional liability insurance does not cover property damage. Claims involving property damage require general liability insurance, which is designed to cover physical damage to property as well as bodily injury incidents​.

Discrimination Claims

Discrimination claims are typically not covered by professional liability insurance. These claims generally require additional coverage through employment practices liability insurance (EPLI), which addresses issues such as discrimination, harassment, and wrongful termination in the workplace​.
