Duty to Defend

Your liability insurer's obligation to provide and pay for a lawyer when you are sued over something your policy might cover, even if the lawsuit is groundless.

Pricing & Contract Mechanics

The duty to defend is broader than the duty to pay (the duty to indemnify). The insurer must defend if the lawsuit alleges any facts that could potentially fall within coverage. Courts typically compare the complaint to the policy, often called the four-corners or eight-corners test. On standard auto, homeowners, and general liability forms, defense costs are paid in addition to your limit; many professional liability policies instead reduce the limit with every legal bill. Compare the two in general liability vs professional liability, and see what is and isn't paid in does liability insurance cover legal fees. For context on all liability coverages, read what liability insurance covers.

Real-World Dollar Scenario

A customer sues Priya's café for $180,000, claiming she slipped on a wet floor. The insurer appoints a lawyer and spends $42,000 on depositions and experts. The case settles for $60,000. Because Priya's general liability policy pays defense outside the limit, the insurer pays all $102,000 and her $1,000,000 occurrence limit is reduced by only the $60,000 settlement. Priya pays $0.

Wallet Risk: What Happens If You Get This Wrong?

Missing the deadline to report a lawsuit, settling privately, or hiring your own lawyer first can forfeit the insurer's defense. You could then pay tens of thousands in legal fees yourself. If you receive a reservation of rights letter, the insurer may later deny payment, so get independent advice. Audit your defense provisions with the 8-Point Policy Check.

Duty to Defend vs. Duty to Indemnify

The duty to indemnify is the insurer's obligation to pay a covered judgment or settlement, decided by the actual facts proven. The duty to defend is decided earlier, by what the lawsuit alleges. So an insurer may have to defend a case it ultimately never pays on. That is why third-party liability coverage is so valuable even when claims are weak.

Regulatory & Editorial Notice: Duty-to-defend standards, reservation-of-rights rules, and independent counsel rights vary by state. Consult a coverage attorney for disputes.
Quick Knowledge Check
A lawsuit against you alleges two things: negligence (covered by your policy) and intentional harm (excluded). What must your liability insurer usually do?
Defend the entire lawsuit, possibly under a reservation of rights
Correct. If any allegation could be covered, most courts require the insurer to defend the whole suit. It may reserve the right to deny payment for the excluded part.
• Refuse to defend because one allegation is excluded
Not quite. One excluded allegation does not cancel the duty to defend when other allegations are potentially covered.
• Defend only the negligence allegation and bill you for the rest
Generally incorrect. Most jurisdictions require a complete defense of a mixed lawsuit, though some allow later reimbursement claims in narrow cases.
