Professional liability insurance (E&O): when your advice is the risk

If you're paid for your expertise — advice, designs, services, professional work — your biggest liability risk usually isn't a client tripping in your office. It's a claim that your work was negligent, wrong, or incomplete and caused the client a loss. General liability insurance won't touch that. Professional liability insurance, also called errors and omissions (E&O) or, for medical fields, malpractice, is the coverage built for the risk that your professional work itself is what's alleged to have caused harm.

What it covers

• Claims of negligence, errors, or omissions in your professional services — bad advice, a missed deadline, a flawed design, a professional standard allegedly not met.
• Legal defense costs, which are often the largest expense even when the claim is groundless.
• Settlements or judgments up to your policy limit.
• It does NOT cover bodily injury or property damage from your premises (that's general liability) or intentional wrongdoing and fraud.

Who needs it

• Consultants, accountants, financial and insurance professionals, lawyers, architects, engineers, and IT/software providers.
• Healthcare providers (as malpractice insurance).
• Real estate agents, designers, marketers, and many freelancers whose deliverables clients rely on.
• Anyone whose contracts require it — clients increasingly demand proof of E&O before signing.

The bottom line

Professional liability (E&O) insurance covers the risk that your work — your advice, service, or deliverable — is alleged to have caused a client harm, along with the legal defense that dominates the cost. It's distinct from general liability, which handles physical injuries and property damage. If your income depends on professional judgment others rely on, you likely need it — and if your policy is claims-made (most are), understand tail coverage so a client can't sue you years later about past work you no longer have coverage for.
