Why defence costs, not damages, are the live issue in most claims
In liability insurance the number everyone quotes is the limit of indemnity, the ceiling on what the policy will pay. The number that actually determines outcomes is often the defence cost, because most liability claims are resolved not by a damages award but by a defended negotiation, and the legal spend to get there can rival or exceed the settlement itself.
A public liability claim, a product-liability action under the Consumer Protection Act, 2019, a professional-indemnity dispute, a directors-and-officers proceeding, each generates lawyers' fees, counsel's fees, expert reports and court costs from the moment it is notified. On a claim that runs for years, as Indian liability disputes do, the defence bill accumulates whether or not the insured is ultimately found liable. A claim successfully defended still costs money to defend, and who pays that, and from which pot, is a policy question, not an afterthought.
That is why the defence-cost terms deserve as much scrutiny at placement as the limit. Two policies with the same headline limit can leave the insured in very different positions once a claim is running, depending on whether defence costs sit inside or outside the limit, who controls the choice of lawyer, how costs are allocated when a claim mixes covered and uncovered allegations, and what happens when the insured and insurer disagree about settling. These mechanics differ across liability lines and between wordings, and this piece works through them as they apply under Indian conventions.
Costs-inclusive versus costs-in-addition: the structure that sets your real cover
The first and most consequential distinction is whether defence costs are paid within the limit of indemnity or in addition to it. It determines how much cover the insured actually has for the damages.
Under a costs-inclusive structure, defence costs and damages share a single limit. Every rupee spent defending the claim reduces the amount left to pay the claimant, so the indemnity available for the settlement shrinks as the defence proceeds. This is the common structure on claims-made liability lines, professional indemnity and directors-and-officers cover in particular, where the defence of complex, document-heavy claims can consume a large share of the limit before any settlement is reached.
Under a costs-in-addition structure, defence costs are paid on top of the limit, so the full limit remains available for the damages and the legal spend does not erode it. This is more typical of occurrence-based general and public liability wordings in the Indian market. The catch is the proportion mechanism that usually accompanies it: where the claim exceeds the policy limit, defence costs are frequently shared between insurer and insured in the same proportion that the limit bears to the total claim, so the insured carries part of the defence cost on a claim larger than its cover.
The same limit therefore buys very different protection depending on this one structural choice. On a costs-inclusive policy, a limit of a given size is really a shared pot for both defence and damages, and a hard-fought claim can burn much of it on lawyers before the claimant is paid. On a costs-in-addition policy, that limit is reserved for damages while defence is funded separately. When comparing quotes, an insured must normalise for this before the limits are comparable at all.
Limit erosion: watching the indemnity drain as the claim runs
On a costs-inclusive policy, limit erosion is the mechanism that turns a comfortable-looking limit into an inadequate one, and it is the single feature most often underappreciated until a claim is well advanced.
Because defence costs draw down the same limit as damages, the money available to settle a claim falls continuously as the claim is defended. A professional-indemnity or D&O matter that involves prolonged investigation, multiple parties, forensic experts and interlocutory skirmishing can consume a substantial part of the limit in defence spend over a couple of years, leaving materially less than the headline figure to fund the eventual settlement. The insured who bought a limit judging it against the likely damages, without accounting for the defence erosion, discovers at settlement that the remaining indemnity no longer covers the exposure.
This has three practical consequences. First, on eroding-limit lines the limit should be sized to cover both a realistic worst-case defence spend and the damages exposure, not the damages alone. Second, the reinstatement position matters: whether the limit reinstates after a claim, and on what terms, affects how exposed the insured is to a second claim in the same period once the first has eroded the cover. Third, the insured has a direct interest in defence-cost discipline, because inefficient or runaway legal spend is not the insurer's loss alone; it is depleting the insured's own indemnity.
On a costs-in-addition policy this dynamic is muted, because the defence spend does not eat the damages limit, though the proportion clause on an over-limit claim reintroduces some of the same exposure. Knowing which structure applies tells the insured whether to worry about erosion at all, and how hard to size the limit for it.
Who controls the lawyer, and consent to incur costs
The second cluster of defence-cost mechanics concerns control: who chooses and instructs the lawyer, and who must consent before costs are incurred. Indian liability wordings resolve this differently across lines, and the difference shapes the insured's experience of a claim.
Most general, public and product-liability policies give the insurer the right to take over and conduct the defence of a claim in the insured's name. Once the claim is notified, the insurer appoints the advocates from its panel, instructs them, and decides how the defence is run, because the insurer bears the exposure and has a legitimate interest in controlling the spend and the strategy. The insured cooperates but does not choose the lawyer.
Claims-made professional lines behave differently. Professional-indemnity and directors-and-officers wordings more often allow the insured a say in, or a choice of, counsel, sometimes from an agreed list, reflecting that these claims touch the insured's professional reputation and that the insured and insurer may not have perfectly aligned interests. The degree of choice is a wording point worth confirming, because an insured with a strong preference for particular counsel needs to know whether the policy accommodates it.
Where the insured genuinely needs its own representation, for a parallel criminal proceeding, or to protect an interest the policy does not cover, that is usually permissible at the insured's own expense, but it should be separated cleanly from the insured civil defence the insurer controls.
Allocation: when a claim mixes covered and uncovered matters
A single claim rarely maps neatly onto a single policy. It commonly bundles allegations that the policy covers with allegations it does not, and defendants who are insured with defendants who are not. Allocation is the mechanism that divides the defence costs and any settlement between the covered and uncovered portions, and it is one of the most contested aspects of liability-claim handling.
The issue arises constantly. A product-liability suit may allege both a covered manufacturing defect and an uncovered contractual warranty breach. A D&O claim may name insured directors alongside the uninsured company on matters the policy excludes. A professional-indemnity claim may mix a covered negligence allegation with an excluded dishonesty allegation. In each case, the insurer's obligation is to fund the defence of the covered part, and the question becomes how much of a shared, indivisible defence effort is properly attributed to it.
Wordings and practice offer competing allocation approaches. A relative-exposure basis divides costs according to the potential liability each covered and uncovered element represents. A larger-settlement basis attributes to the uncovered parties only the additional cost their presence caused, on the reasoning that the insurer would have had to fund the covered defence anyway. The two can produce very different splits, and the wording, or its silence, leaves room for dispute exactly when the claim is most expensive.
The practical defences are two. At placement, prefer wordings that state the allocation basis rather than leaving it open, and secure the broadest reasonable definition of what is covered so fewer allegations fall outside. At claim, engage the allocation question early and in writing, rather than letting defence costs accumulate on an undefined split that the insurer later seeks to resolve in its favour. An allocation left to be argued after the spend is incurred is an allocation the insured usually loses ground on.
Settlement consent and the hammer clause
The final defence-cost mechanic is what happens when the insured and the insurer disagree about whether to settle, and here the wording contains a device that can quietly transfer risk back to the insured: the settlement-consent or hammer clause.
The starting point is mutual consent. The insured cannot settle a claim without the insurer's agreement, because a settlement binds the insurer's money. Equally, many wordings provide that the insurer will not settle without consulting the insured, particularly on professional lines where a settlement carries a reputational admission. The tension surfaces when the insurer wants to settle and the insured refuses, usually because the insured wants to contest liability on principle or to protect its reputation.
The hammer clause resolves that tension in the insurer's favour. It provides that if the insurer is willing to settle within the limit and the insured refuses to consent to that settlement, the insurer's liability is capped at the amount for which the claim could have been settled, plus the defence costs incurred up to that point. Everything beyond, the extra damages and the further defence costs of fighting on, falls to the insured. The clause exists so that an insured cannot force the insurer to fund a costly continued defence and a larger eventual award simply because the insured prefers to fight.
Some wordings soften the clause, capping the insured's share of the excess at a percentage rather than the full amount, which is a negotiable point at placement worth pressing for on lines where the insured values its right to contest.
Reading the defence-cost terms across lines before you place
Defence costs are not a single mechanism but a set of interacting terms, and they behave differently on each liability line. The disciplined placement reads them together, across the whole programme, so a claim that touches more than one policy does not fall into a gap between inconsistent defence provisions.
The checklist is short and repeatable. On each liability policy, establish whether defence costs are inside or in addition to the limit, and normalise the limits for comparison on that basis. On eroding-limit lines, size the limit for defence plus damages and confirm the reinstatement position. Confirm who controls counsel and whether the insured has any choice. Confirm the consent-to-incur-costs condition and build the notify-before-you-spend discipline into the claims protocol. Check whether the wording states an allocation basis for mixed claims. And read the settlement-consent and hammer clause, and negotiate a softened version where the right to contest matters.
The recurring failure across all of these is comparing liability policies on limit and premium alone, as if a limit meant the same thing on every wording. It does not. A costs-inclusive limit with a full hammer clause and insurer-controlled counsel is a materially different cover from a costs-in-addition limit with a softened hammer and a choice of counsel, at the same headline figure.
This is where wording comparison earns its place. Sarvada makes insurer policy wordings searchable, so a broker can pull the defence-costs, allocation and settlement-consent clauses from competing public-liability, product-liability, professional-indemnity and D&O forms side by side and see exactly how each treats erosion, control and the hammer before binding. When a claim's economics turn on whether defence spend ate the limit or whether a hammer clause shifted the excess to the insured, being able to read those clauses across the market is the difference between a cover that holds and one that surprises.
