How Do Error & Omission Liability Insurance Works

E&O insurance works by providing financial protection to professionals in case they make mistakes or omissions in their professional services or advice. Here’s how it typically works:

Purchase Coverage

First, you need to find an insurance provider that offers E&O liability insurance and purchase a policy. The coverage and cost will depend on various factors, such as your profession, business size, and risk level.

Policy Terms

Once you have the policy, review the terms and conditions carefully. Understand what is covered, any exclusions or limitations, and the policy limits – the maximum amount the insurance will pay for a claim.

Accusation or Claim

If a client accuses you of making mistakes, omissions, or providing inadequate advice, they may file a claim against you. This could be due to financial loss, reputational damage, or other harm they believe resulted from your professional services.


As soon as you become aware of a potential claim, you must notify your insurance provider or agent. They will guide you through the claims process and provide you with the necessary assistance.

Investigation and Defense

The insurance company will investigate to assess the validity of the claim. They may hire lawyers and experts to defend you if necessary. The insurance will cover legal defense costs, including lawyer fees, expert witness fees, and other related expenses.

Settlement or Judgment

If the claim is valid, the insurance company will work with you to negotiate a settlement with the affected client. If a settlement cannot be reached and the claim goes to court, the insurance will cover any judgments or damages awarded to the client up to the policy limits.

Deductibles and Premiums

It’s important to note that E&O insurance policies often come with deductibles, which you must pay out of pocket before the insurance coverage kicks in. Additionally, you will need to pay premiums regularly to maintain the coverage.

What is Covered?

Professional Mistakes

E&O insurance protects you if a client accuses you of making errors or omissions in your professional services or advice. It covers claims related to negligence, mistakes, or failure to deliver the promised results.

Legal Defense Costs

If you face a lawsuit, E&O insurance covers the costs of hiring lawyers and experts to defend you. These legal defense expenses can add up quickly, so having insurance can alleviate the financial burden.

Damages and Settlements

E&O insurance helps cover any damages or settlements that may be awarded to the client. This can include compensatory damages for financial loss, reputational damage, or other harm caused by your professional services.

Alleged Negligence

If a client claims that your advice or service was inadequate or negligent, E&O insurance provides coverage. It can protect you from financial losses resulting from professional negligence claims.

Breach of Contract

E&O insurance may also cover claims related to breach of contract, such as failing to deliver services as agreed upon in the contract.

Advice and Consultation

For professions that involve offering advice or consultation, E&O insurance covers claims arising from incorrect advice, misleading information, or professional opinions that lead to financial harm for the client.
