Hammer Clause
A hammer clause, also called a consent-to-settle or blackmail settlement clause, limits the insurer's obligation if the insured refuses a settlement the insurer recommends, typically capping payment near the settlement amount plus defense costs to that point, or splitting later costs.
Last updated October 13, 2026
How a hammer clause works
Many professional liability and management liability policies require the insurer to obtain the insured's approval before settling a claim, so the insurer cannot settle over the insured's objection. The hammer clause is the counterweight. If the insurer recommends a settlement the claimant will accept and the insured refuses, the policy limits what the insurer pays afterward.
Under a full (hard) hammer clause, the insurer's liability is typically capped at the amount for which the claim could have been settled, plus defense costs incurred up to that point. Future defense costs and any amount above the proposed settlement fall to the insured. A softer version, often called a coinsurance or soft hammer, splits the additional damages, and sometimes defense costs, between insurer and insured in stated percentages after a refusal. Exact terms vary by policy.
How a hammer clause is triggered
- The claimant offers to settle for a specific amount.
- The insurer recommends accepting. The policy requires the insured's consent before the insurer can settle.
- The insured declines.
- The clause then limits the insurer's responsibility for what follows, such as a higher settlement, a judgment or further defense costs.
The clause typically applies only when the insurer actually recommends the settlement and the claimant is willing to accept it. Wording varies, so the policy sets the exact trigger. Hammer clauses commonly appear in claims-made professional liability forms, including technology E&O, and in management liability forms such as D&O, among others.
Example
A hypothetical claimant offers to settle a professional liability claim for $200,000. The insurer recommends accepting, but the insured declines because it wants to protect its reputation. The case later ends in a $500,000 judgment. Under a full hammer clause, the insurer may owe only about $200,000 plus earlier defense costs, leaving the insured to pay the rest. Under a soft hammer, the insurer and insured would share the extra amount according to the policy's split.
What to watch for
- Hard or soft: check whether the clause is a full cutoff or a coinsurance split, and what percentages apply.
- Defense costs after refusal: some clauses stop insurer funding of further defense, others share it.
- Consent language: look for whether the insured's consent is required at all, and how the insurer must communicate a recommended settlement.
- Negotiability: some insurers will agree to soften a hammer clause, particularly at renewal, though terms vary.
- Related concept: see consent to settle.
Hammer clause vs. related terms
- Hammer clause vs. consent to settle. A consent-to-settle provision requires the insured's agreement before the insurer settles. The hammer clause is the consequence when the insured withholds that agreement against the insurer's recommendation.
- Hammer clause vs. insurer settlement authority. Some policies let the insurer settle without the insured's consent. In those, no hammer clause is needed, because the insured cannot block the settlement.
- Hammer clause vs. duty to defend. The duty to defend concerns who provides and pays for the defense. A hammer clause can limit how long the insurer pays for that defense after a refusal.
- Soft hammer vs. property coinsurance. A soft hammer is sometimes called a coinsurance clause, but it is unrelated to the coinsurance penalty in property insurance.
- Hammer clause vs. reservation of rights. A reservation of rights is the insurer's notice that it may contest coverage. It addresses coverage, not settlement decisions.
A second example: a soft hammer clause
A hypothetical claimant offers to settle for $300,000. The insurer recommends accepting, but the insured refuses and the case continues. Defense costs after the refusal reach $150,000, and the matter later settles for $500,000. Under a soft hammer clause that splits costs after refusal 70 percent to the insurer and 30 percent to the insured, the amount above the original offer ($200,000) plus the later defense costs ($150,000) totals $350,000. The insurer would pay about $245,000 and the insured about $105,000, in addition to the original $300,000 the insurer would have paid, all subject to the limit and retention. The split, and whether defense costs are included in it, varies by policy. The percentages here are invented for illustration.
Questions to ask your broker or underwriter
- Is the clause hard or soft, and what percentages apply?
- Does it cap future defense costs, share them, or leave them alone?
- Is the insured's consent required for every settlement, and must it be "reasonable"?
- How and when must the insurer communicate a settlement recommendation?
- Does the clause apply to the retention, and how do the retention and limit interact with the split?
- Do the limit and the clause interact if a judgment exceeds the limit?
- Can the clause be softened, reduced or removed at renewal?
What to do when you receive a settlement recommendation
- Ask for the recommendation in writing, along with the insurer's reasoning.
- Review the hammer clause and how the policy would apply it before you decide.
- Talk with your counsel and broker about the costs and risks of continuing the case.
- Weigh reputation, precedent and customer relationships against the financial consequence in dollars.
- Respond in writing and keep a record of how and when you replied.
Common mistakes
- Not reading the clause until a claim arrives.
- Assuming the insurer will cover everything even after the insured rejects a recommended settlement.
- Refusing a settlement informally, without understanding the written consequences.
- Treating a hard hammer and a soft hammer as the same thing.
- Missing the chance to negotiate the clause at renewal.
Why it matters for technology, AI, fintech and digital-asset companies
Technology companies often care about product reputation, customer relationships and precedent, so they may resist settling even a modest claim. A hammer clause makes that choice a financial trade-off. It is most common in E&O, D&O and similar claims-made forms, so it is worth checking in the wording for your errors and omissions and D&O programs before a claim arises.
For AI and software companies, a settlement can seem to imply that a model or product failed, and some companies worry about precedent with other customers. Those concerns are legitimate, and a hammer clause makes them part of a financial calculation. That is why technology E&O and cyber and AI liability wording is worth checking along with D&O. Reviewing the clause before binding gives the company the chance to negotiate it.

Frequently asked questions
What is a hammer clause?
A hammer clause, also called a consent-to-settle or blackmail settlement clause, limits the insurer's obligation if the insured refuses a settlement the insurer recommends, typically capping payment near the settlement amount plus defense costs to that point, or splitting later costs.
What is the difference between a hard hammer and a soft hammer clause?
A hard or full hammer clause typically caps the insurer at the proposed settlement amount plus defense costs to that point if the insured refuses. A soft hammer splits later damages, and sometimes defense costs, between insurer and insured in set percentages. The percentages vary by policy.
Why do insurers include hammer clauses?
They discourage an insured from rejecting a reasonable settlement and then exposing the insurer to a larger judgment or a longer, costlier defense. The clause aligns incentives by making the insured share in the consequences of refusing a recommended settlement.
Can a hammer clause be negotiated?
Sometimes. Some insurers will agree to a softer version, change the percentages, or delete the clause, particularly at renewal. Terms differ by insurer and policy type, so it is a point worth raising with your broker before binding.
Does a hammer clause apply if the insurer did not recommend the settlement?
Generally no. The clause is typically triggered when the insurer recommends a settlement the claimant will accept and the insured refuses. If the insurer did not make that recommendation, the clause may not apply, but the exact trigger is in the policy wording.
What is the difference between consent to settle and a hammer clause?
Consent to settle gives the insured a say, because the insurer needs agreement before settling. A hammer clause limits the insurer's obligation if the insured refuses a recommended settlement. The two are often found together in the same policy.
Can an insurer settle a claim without my consent?
It depends on the policy. Some policies let the insurer settle at its discretion, and others require the insured's consent. A hammer clause generally appears in policies that require consent. Check the settlement and consent provisions of your policy.
Are hammer clauses common in cyber and technology E&O policies?
Hammer or similar consent provisions appear in many claims-made professional liability and management liability forms, including some technology E&O and cyber policies. Wording differs by insurer, so read the settlement terms in each policy.
