What it means
Imagine a customer sues a company after tripping in its shop. The company passes the claim to its liability insurer, which hires a solicitor or attorney to respond, gathers evidence and negotiates or goes to trial if needed.
The policyholder is spared the cost and stress of finding and paying for its own legal team. The duty to defend is triggered by the allegations in the claim, not by whether they are true.
If the claim describes something that could fall within the policy, the insurer generally has to defend until it is clear that no cover exists. This is why the duty to defend is often described as broader than the duty to indemnify, which is the separate duty to pay a judgment or settlement.
How defence costs are treated matters a great deal for the amount of protection available. Under a defence outside limits arrangement, legal fees are paid on top of the policy limit, so the full limit remains for damages.
Under a defence inside limits arrangement, sometimes called an eroding or burning limit, each dollar spent on lawyers reduces what is left for settlements and judgments. The insurer normally controls the defence and chooses the lawyers, because it is paying.
The policyholder must cooperate, give notice promptly and avoid admitting liability or settling without consent. In some situations, such as when the insurer is defending under a reservation of rights because cover is in doubt, the policyholder may be entitled to select independent counsel.
Insurance defence work is also a specialist branch of the legal profession. Lawyers who act for insurers usually handle high volumes of similar claims, such as accidents, professional negligence and property damage, and they report to claims managers as well as to the policyholder.
Their fees are often set by agreed rate schedules and billing guidelines. Businesses should read the defence provisions as carefully as the headline limit.
A policy that looks generous at $1,000,000 may protect much less if a complex lawsuit consumes most of the limit in legal fees. Directors and officers, professional indemnity and cyber policies frequently use inside limits for this reason.
In practice
Real-world examples.
Example
A restaurant is sued by a diner who claims food poisoning. The restaurant's liability insurer assigns a defence lawyer, collects supplier records and health inspection reports, and negotiates a settlement without the owner paying any legal fees.
Example
A software consultancy is accused of delivering faulty work that caused a client to lose revenue. The professional indemnity insurer agrees to defend under a reservation of rights while it investigates whether the claim falls within the policy.
Example
A manufacturer receives a product liability claim after a customer is injured by a machine. The insurer hires specialist engineers as expert witnesses as part of the defence, and the cost counts against the policy limit because the policy is written on an inside-limits basis.
Formula
Calculation
Limit remaining for damages (defence inside limits) = Policy limit - Defence costs paid
Limit remaining for damages (defence outside limits) = Policy limit
A consulting firm has a professional liability policy with a limit of $1,000,000. A client sues, and the lawyers appointed by the insurer bill $350,000 before the case settles. If defence is inside limits, the remaining amount for settlement is 1,000,000 - 350,000 = $650,000. If defence is outside limits, the full $1,000,000 is still available, because the $350,000 is paid in addition to the limit.Case study
Seen in the real world.
Kingsbridge Components is an illustrative, fictional manufacturer that held a $2,000,000 product liability policy with defence costs inside the limit. A customer alleged that a faulty part caused a factory fire and sued for $1,800,000.
The case took two years of expert reports, depositions and pre-trial motions, and the insurer's defence lawyers billed $900,000. When the claim was finally settled at $1,500,000, only $1,100,000 of the limit remained, so the company had to pay the $400,000 shortfall from its own funds.
The fictional finance director learned that the policy's limit was not the same as the amount available for damages. The illustrative lesson is that companies should check whether defence costs sit inside or outside the limit, and consider buying higher limits or an outside-limits policy for high-exposure risks.
Watch out
Common mistakes.
- Assuming that the policy limit is entirely available to pay damages, when defence inside limits can use up a large part of it before any settlement.
- Hiring your own lawyer and settling the claim without telling the insurer, which can breach policy conditions and put cover at risk.
- Believing that the insurer will only defend claims that it expects to pay, when the duty to defend usually applies to any claim that could potentially fall within the policy.
Questions
People also ask.
What is the difference between the duty to defend and the duty to indemnify?
The duty to defend is the insurer's obligation to provide and pay for legal defence, while the duty to indemnify is its obligation to pay a covered settlement or judgment.
What is a reservation of rights?
It is a notice from the insurer that it will defend the claim but may later deny cover, which protects the insurer's position while the facts are investigated.
Who controls the defence of the claim?
The insurer usually appoints the lawyers and directs the strategy, although the policyholder keeps duties to cooperate and must agree to any settlement above the policy terms.
