Lawyers Professional Liability Hammer Clause: What Attorneys Need to Know

Legal malpractice claims can place attorneys in a difficult position. Even when a lawyer believes they have done nothing wrong, the insurance company may recommend settling a claim to avoid the significant costs of litigation. This is where the Lawyers Professional Liability Hammer Clause becomes an important policy provision to understand.

Subject to a Hammer Clause, attorneys are surprised to learn they have the right to approve or reject a settlement, but rejecting an insurer’s recommendation can have serious financial consequences. Understanding how a Hammer Clause works can help law firms make informed decisions when evaluating professional liability insurance policies.

What Is a Lawyers Professional Liability Hammer Clause?

The term Hammer Clause is an insurance industry nickname rather than an official policy definition. It typically appears within the defense, settlement, or cooperation provisions of a lawyers professional liability insurance policy.

A Hammer Clause allows the insured attorney to refuse a settlement recommended by the insurance company. However, if the attorney chooses not to settle, the Hammer Clause limits coverage to the proposed settlement, plus certain defense expenses incurred up to that point.

In practical terms, the insurer is effectively saying:

“You have the right to reject our settlement recommendation, but if the case ultimately costs more, you may be responsible for the additional expense.”

Why Do Insurers Include a Hammer Clause?

Insurance carriers evaluate claims differently than attorneys facing allegations of malpractice. Attorneys prioritize their reputation and conduct, while insurers assess claims based on probable monetary impact.

Claims professionals typically consider:

      • The likelihood of winning the case
      • Estimated defense costs
      • Potential settlement amounts
      • Possible indemnity payments
      • Overall cost of resolution

A malpractice insurer may determine that settling for a small amount is financially preferable to spending hundreds of thousands of dollars defending a claim through trial.

Why Attorneys May Resist Settlement

Certain attorneys are understandably reluctant to settle a claim when they believe they have not committed malpractice. Common reasons include:

      • Protecting professional reputation
      • Avoiding a claim payment on loss history
      • Preventing higher future insurance premiums
      • Seeking vindication through a favorable outcome

Attorneys may view settling a claim as an implied admission of fault, even if they did nothing wrong.

How a Hammer Clause Works

Consider a simplified example:

An insurer recommends settling a malpractice claim for $50,000. The attorney refuses because they believe the claim lacks merit.

The case proceeds to trial, resulting in:

      • $300,000 in defense costs
      • $100,000 judgment against the attorney

A Hammer Clause caps, the insurer’s obligation at the amount it would have paid to settle the claim, along with applicable defense costs incurred before the settlement recommendation. Any additional expense could become the responsibility of the insured attorney. Given this example the attorney pays $350,000.

This potential financial exposure is why attorneys should carefully review settlement provisions before purchasing a professional liability policy.

Are All Lawyers Professional Liability Policies the Same?

No. Certain lawyers professional liability policies include a traditional Hammer Clause, while others provide softer approach.

Certain policies state that the insurer will not settle a claim without the insured’s written consent and do not contain language limiting the insurer’s liability if the insured refuses a recommended settlement.

Because policy language varies, attorneys should review defense and settlement provisions closely and discuss them with a knowledgeable insurance advisor.

The Hidden Cost of Vindication

Even when an attorney successfully defends a malpractice claim, the financial consequences may continue.

In addition to financial consequences before an attorney decides to fight, there will be substantial non-billable hours spent preparing for trial, depositions, and attending trial.

Professional liability insurers often consider claim history and defense costs during renewal underwriting. Significant defense expenditures can affect future coverage availability and pricing, even without an indemnity payment. Substantial defense costs may contribute to non-renewal situations and could force attorneys into higher-cost surplus lines coverage.

As a result, winning a case may not always eliminate the long-term insurance impact.

Moral victories are expensive.

Key Questions to Ask Before Buying Coverage

When evaluating lawyers professional liability insurance, attorneys should ask:

      1. Does the policy contain a Hammer Clause?
      2. What are the terms for “consent to settle”?
      3. What happens if I reject a settlement recommendation?
      4. Are there any modified or soft Hammer Clause provisions?
      5. How could defense costs affect future renewals?

Understanding these details before a claim arises can prevent unexpected financial exposure.

Before selecting or renewing coverage, attorneys should carefully review their policy’s defense and settlement language. A thorough understanding of the Hammer Clause can help protect both a law firm’s finances and its long-term insurance strategy.
