Also known as: hammer clause · blackmail clause · settlement cap provision
A hammer clause is a liability policy provision that limits how much your insurer must pay if you refuse to consent to a settlement it recommends and the claim later resolves for more.
A hammer clause is a condition in many liability policies (commonly D&O, E&O, and professional liability) that discourages you from blocking a settlement your insurer wants to make. If the insurer can settle a covered claim for a set amount but you refuse to consent and demand the case continue, a full or traditional hammer clause caps the insurer's liability at the amount it could have settled for plus defense costs incurred up to the date you refused, leaving you to pay any excess judgment or settlement. Many modern policies soften this with a modified or soft hammer clause, under which the insurer and the insured share the amount above the proposed settlement, for example the insurer pays 70 to 80 percent and you pay the rest. The clause works hand in hand with your consent-to-settle rights: you keep a say in whether to settle, but the hammer clause is what puts real cost on saying no. For a startup founder or CFO, this provision decides how much protecting your reputation by fighting a claim could cost you out of pocket.
A hammer clause is a liability policy provision that limits your insurer's payout when you refuse to consent to a settlement the insurer recommends and can achieve. If you insist on fighting the claim and it later resolves for more, a full hammer clause caps the insurer's obligation at the amount it could have settled for plus defense costs up to that point, and you pay the difference. It is sometimes called a blackmail clause because it pressures the insured to accept the insurer's settlement recommendation.
A full or traditional hammer clause makes the insured bear all of the loss above the settlement the insurer could have reached, so refusing to settle shifts the entire excess onto you. A soft or modified hammer clause splits that excess between the insurer and the insured in an agreed ratio, for example the insurer paying 70 to 80 percent and the insured paying the remainder. Soft versions are more favorable to the policyholder because they cap how much a decision to keep fighting can cost you.
Consent-to-settle language gives you the right to approve or reject a settlement, while the hammer clause sets the financial consequence of withholding that consent. Together they mean you can decline a settlement to protect your reputation, but you may then be responsible for some or all of any larger amount the claim ultimately costs. Always read the two provisions side by side so you know how much control you truly have and what it could cost to use it.
