Claims-Made vs. Occurrence Policies: What Every Attorney Needs to Know

As an attorney, your expertise lies in navigating the complexities of the law, not the fine print of insurance contracts. Yet, one of the most critical decisions you'll make for the financial health of your practice involves understanding a fundamental distinction in your professional liability policy: whether it's a "claims-made" or an "occurrence" policy.

Choosing the wrong type—or more accurately, misunderstanding the structure of the policy you have—can lead to devastating gaps in coverage. At LawyersIns.com, we believe an informed attorney is an empowered one. Let's break down the difference between claims-made vs. occurrence lawyers malpractice insurance so you can confidently protect your practice and your personal assets.

Understanding Occurrence Policies

An occurrence policy provides coverage for an alleged act of professional negligence that *occurred* during the policy period, regardless of when the claim is actually filed.

Think of it like this: If you had an occurrence policy from 2020 to 2021 and committed an error during that time, that policy would respond to a resulting claim, even if it were filed five years later in 2026. The trigger for coverage is the date of the incident, not the date the claim is made.

While this structure is common for general liability or auto insurance, it is extremely rare—and often prohibitively expensive—for lawyers professional liability insurance. This is due to the "long-tail" nature of legal malpractice claims, where an error may not be discovered for many years.

Understanding Claims-Made Policies

A claims-made policy is the industry standard for legal professional liability. It provides coverage for a claim that is both *made against you* and *reported to the insurer* during the active policy period.

For a claim to be covered under a claims-made policy, two conditions must typically be met: - The alleged wrongful act must have taken place on or after the policy's **retroactive date**. - The claim must be made and reported while the policy is in force.

The retroactive date, or "prior acts date," is a critical feature. It’s the date after which your professional services are covered. When you first buy a policy, this date is usually the inception date. As you renew your policy each year with the same carrier, you maintain that original retroactive date, ensuring continuous coverage for all your past work since that date.

Claims-Made: The Standard for Legal Professional Liability

Insurers overwhelmingly use the claims-made form for lawyers because it provides certainty. It allows them to price policies based on a defined, one-year risk window. If they had to use an occurrence form, they would need to predict the cost of claims that might not be filed for a decade or more, making premiums unaffordable for most law firms.

The claims-made structure benefits law firms by offering lower initial premiums. As your practice matures and your "prior acts" exposure grows, your premium will gradually "step up" over the first five to seven years before leveling off. This makes it a more manageable and predictable expense for your firm's budget.

Don't Get Caught Without a Tail: Understanding Extended Reporting Periods (ERPs)

The single biggest pitfall of a claims-made policy is a potential coverage gap when the policy ends. What happens if you retire, dissolve your firm, or switch insurance carriers, and a claim from your past work arises *after* your last policy has expired?

This is where an **Extended Reporting Period (ERP)**, commonly known as **"tail coverage,"** becomes essential.

An ERP is an endorsement you purchase that extends the window of time you have to *report* a claim after your policy has been canceled or non-renewed. It does not cover acts committed after the policy ended; it only provides coverage for claims arising from services you rendered before the policy terminated.

You will likely need to purchase tail coverage when: - **Retiring or leaving the practice of law:** To protect your personal assets from claims that may surface years into your retirement. - **Closing or selling your firm:** To properly wind down the firm's liabilities. - **Changing careers:** For example, if you are appointed to the bench. - **Switching insurance carriers:** If your new carrier is unwilling or unable to provide prior acts coverage back to your original retroactive date.

Claims-Made vs. Occurrence: A Real-World Scenario

Let's illustrate with an example.

Attorney David ran a successful solo practice from 2015 to 2025 and maintained a claims-made malpractice policy the entire time. In June 2025, he decides to retire. He lets his policy expire on its renewal date of July 1, 2025.

In 2027, a former client discovers a significant error David made in a 2023 contract negotiation and files a malpractice suit against him.

• **Scenario 1 (No Tail Coverage):** David reports the claim to his former insurer. They deny the claim. Even though the error occurred when he was insured, the claim was not *made and reported* during an active policy period. David is now personally responsible for his defense costs and any potential judgment.

• **Scenario 2 (With Tail Coverage):** When David retired, he purchased an ERP from his insurer. When the 2027 claim is filed, he reports it. Because the tail coverage extended his reporting period, the insurer treats the claim as if it were reported during his last active policy. His defense is covered, protecting his retirement savings.
