Professional liability insurance, also known as errors and omissions (E&O) insurance, helps to cover your business if a customer claims you messed up, missed something important, or otherwise failed to deliver the service you promised. If a customer believes you’ve made a mistake in your professional services, even if it’s a false allegation, you risk being sued and having to pay legal fees out of pocket without this important coverage.
If your business provides advice, expertise, or specialized services, you should consider professional liability insurance to help protect against potentially expensive lawsuits. Coverage may even be required, depending on your profession, clients, licensing requirements, or state regulations.

What is professional liability insurance?
Professional liability (or errors and omissions) insurance helps protect businesses that provide professional services or advice when clients claim they made a mistake, acted negligently, or failed to fulfill their professional responsibilities. It can help pay for legal defense costs, settlements, and court judgments, up to your policy limits.
Covered claims may involve negligence, errors and omissions, misrepresentation, missed deadlines, breach of professional duty, and other mistakes that cause a client financial harm. Some policies may also cover claims involving libel, slander, or copyright infringement, though coverage varies by insurer.
How does professional liability insurance work?
When a client or customer requests compensation or sues you for reimbursement for damages due to alleged professional negligence or failure to perform, you can notify your insurance provider and make a claim to cover the costs of various legal fees. Your insurance will only cover you up to your coverage limits and may require a deductible payment—which is subtracted from your claim settlement.
Your professional liability insurance will work on either a claims-made or occurrence policy, which will determine when you’ll need to file a claim with your insurer:
- Claims-made: Covers claims made during the policy period. May cover retroactive claims on or after a specific date. Purchasing “tail coverage” can extend your coverage after your policy expires, generally by an additional 30 to 60 days.
- Occurrence: Covers claims for incidents made during your policy period, regardless of when you make the claim. These types of policies may be more expensive than claims-made policies.
What does professional liability insurance cover?
Professional liability covers various legal costs when sued for alleged failure to meet professional responsibilities, such as errors or omissions. We’ll cover some of the main types of coverage below.
Professional negligence
Professional liability insurance can cover lawsuits over negligence in services that result in a financial loss for your client or customer. For example, if an architect designs structural plans containing a significant error that causes a costly project delay, professional liability insurance may help cover the resulting lawsuit.
Errors and omissions
Your professional liability policy will cover claims where your business makes a professional mistake, even if it was unintentional. For example, if your technology consulting business provides incorrect information involving consumer safety laws or doesn’t mention key details to a client, you could be covered for the resulting damages when they need to rebuild it.
Misrepresentation
Professional liability insurance can cover claims that your business did not accurately describe itself or its services to customers. For example, if a real estate agent sells a house by claiming it could be used as a rental unit in an area where that is prohibited, you could be covered for a resulting lawsuit.
Missed deadlines
Professional liability coverage can cover claims where your customers or clients sue over a financial loss from you missing an agreed-upon deadline. For example, if a graphic designer failed to deliver a time-sensitive commission for their client, they could be covered for a resulting lawsuit or financial damages.
Legal defense costs
Professional liability insurance can help cover your defense costs when sued due to alleged mistakes in your professional services. This can include legal fees such as attorney costs and other court costs, even if you’re found not to have made any professional mistakes.
Settlements
If you’re liable for mistakes or negligence in your professional services or advice, professional liability insurance can help pay for the settlement costs of the damages to your client.
Judgements
If you’re found liable for damages to a client in court due to mistakes or errors in your professional services, professional liability insurance can help cover how much you’re sentenced to repay your client.
Copyright or intellectual property issues
Professional liability coverage may protect your business from lawsuits involving copyright claims. For example, if your graphic design business was alleged to have used an already copyrighted character as a mascot for a business client. However, this coverage can vary between insurance companies and could be excluded.
Breach of professional duty
Professional liability insurance can help cover you for failing to perform services that you’re responsible for doing as part of a contract. For example, if your home inspection business was contracted to review a homeowner’s crawlspace for damage and you failed to complete a required inspection, you could be covered for a lawsuit.
