What is a hammer clause in a malpractice policy?

A hammer clause — formally called a settlement cap provision or consent-to-settle limitation — is a policy provision that penalizes you financially if you refuse to accept a settlement recommended by your carrier and the case ultimately resolves for more than the proposed settlement amount.

The basic mechanics work like this: your carrier investigates a claim and negotiates a settlement of $200,000 that the claimant will accept. The carrier recommends settlement, but you refuse because you believe you did nothing wrong and want to defend your reputation. The case goes to trial and results in a $500,000 judgment. Under a full hammer clause, the carrier's liability is capped at the $200,000 settlement they recommended, and you are personally responsible for the remaining $300,000 plus any additional defense costs incurred after you rejected the settlement.

Hammer clauses come in varying degrees of severity. A full hammer clause caps the carrier's liability at the proposed settlement amount — you bear 100% of the excess. A modified or soft hammer clause shares the excess between you and the carrier, typically 50/50 or 70/30, reducing your personal exposure. Some policies have a coinsurance hammer where you pay an increasing percentage of costs after rejecting settlement.

The hammer clause often accompanies consent-to-settle provisions. If your policy gives you the right to consent to or refuse settlements (which is valuable for protecting your reputation), the carrier wants a counterbalance to prevent you from irrationally refusing reasonable settlements that increase their exposure.

When evaluating policies, look for soft hammer clauses rather than full hammer clauses. The ideal policy provides both consent-to-settle rights and a modified hammer clause that limits your exposure without eliminating your ability to defend meritless claims.

Some specialty legal malpractice carriers offer policies with no hammer clause at all, but these typically come at a premium of 5% to 15% above comparable policies with hammer provisions.
