Professional liability insurance protects attorneys against claims alleging errors, omissions, or negligent acts arising from legal services.
Most professional liability insurance for lawyers, including the only professional liability insurance sponsored by the State Bar of California, is written on a claims-made and reported basis. Under this structure, coverage is determined by timing. The policy responds based on when a potential claim is identified and reported, not solely on when the legal work was performed.
A claims-made and reported policy applies to matters that first come to the attorney’s attention while the policy is in force, provided the matter is reported to the insurer in accordance with the policy’s notice requirements.
In other words, coverage is intended to apply when:
- The attorney was not aware of the potential claim before the policy began, and
- The attorney reports the matter during the policy period or applicable reporting window
This structure differs from coverage models that focus only on when the underlying work was performed. With claims-made and reported professional liability insurance, coverage follows the policy in force at the time the issue is identified and properly reported, rather than the policy in place when legal services were rendered.
Claims-Made vs. Occurrence: A Structural Comparison
Professional liability insurance for attorneys is typically written on a claims-made and reported basis. This differs from occurrence-based coverage, which is more common in other types of insurance.
How the Two Policy Structures Differ
Claims-Made and Reported Policies
- Coverage is triggered when a claim is first identified and reported during the policy period
- The alleged wrongful act must occur on or after the retroactive date
- Coverage follows the policy in force at the time the claim is reported
- Continuity of coverage and timely reporting are critical
Occurrence Policies
- Coverage is triggered by when the incident occurs, regardless of when the claim is reported
- Each policy year stands on its own
- Coverage does not depend on future renewals or reporting periods
- Retroactive dates and extended reporting periods generally do not apply
Why This Distinction Matters for Attorneys
Legal malpractice claims often arise long after legal services are performed. Claims-made and reported policies allow professional liability coverage to respond based on when a potential issue becomes known and when it is reported, rather than attempting to tie coverage solely to the date legal work occurred.
This approach provides a clear and administrable framework for handling claims that emerge long after representation ends.

The Role of the Retroactive Date in Claims-Made Policies
A key feature of a claims-made and reported professional liability policy is the retroactive date. This date establishes how far back coverage reaches for prior legal work.
Under a claims-made and reported policy, a claim may be made and reported during the current policy period, but the underlying wrongful act must have occurred on or after the retroactive date shown in the policy. If the alleged error or omission took place before that date, the claim will not be covered, even if the policy is otherwise in force.
The retroactive date typically corresponds to when an attorney first obtained professional liability coverage or when prior acts coverage was established. As long as coverage remains continuous, that date generally remains unchanged from year to year.
Problems arise when coverage lapses or when an attorney changes policies without maintaining the same retroactive date. In those situations, work performed before the new retroactive date may fall outside the scope of coverage, creating uninsured exposure for past matters.
Statutes of Limitation and Practice Area Risk
The timing of professional liability claims is influenced not only by insurance structure, but also by the nature of an attorney’s practice and the applicable statutes of limitation. In many areas of law, a claim may arise long after the underlying work is completed, sometimes years after a matter is closed.
Under a claims-made and reported professional liability policy, this delayed discovery is significant. Coverage depends on when the attorney first becomes aware of a potential claim and when it is reported, not when the legal services were performed. Attorneys who understand the statute of limitations applicable to their practice areas are better positioned to assess how long exposure may extend beyond the life of a matter.
This is why uninterrupted coverage matters. Even when no claim appears likely, past work can remain a source of potential liability for years. Claims-made coverage is designed to respond to that reality, but only when reporting and coverage continuity are maintained.
What Happens When Coverage Ends or Changes
Claims-made and reported professional liability insurance requires careful attention when coverage ends or changes. Unlike other policy structures, coverage does not automatically follow past work once a policy terminates.
Coverage may end or change for a variety of reasons, including retirement, firm dissolution, changes in practice structure, or a decision to move coverage to a different carrier or program. When this happens, the ability to report future claims tied to prior work may be affected.
If a claim arises after a policy has ended and no reporting mechanism remains in place, that claim may not be covered, even if the legal work was performed while the policy was active. This is a common area of misunderstanding, particularly when an attorney assumes that prior coverage continues indefinitely for past matters.
Transitions are also where retroactive dates and reporting requirements intersect. Maintaining continuity of coverage, preserving the same retroactive date, and understanding post-policy reporting options are essential to avoiding unintended gaps.
For attorneys considering any change to their professional liability coverage, the mechanics of how a claims-made and reported policy responds after termination should be evaluated as carefully as the coverage in force during active practice.
Extended Reporting Periods and Continued Reporting Access
When a claims-made and reported professional liability policy ends, the ability to report future claims tied to prior work does not automatically continue. This is where extended reporting periods, often referred to as tail coverage, become relevant.
An extended reporting period allows an attorney to report claims after the policy has terminated, provided the alleged wrongful act occurred on or after the policy’s retroactive date and before the policy ended. It does not create new coverage for future work, nor does it change the retroactive date. It simply preserves the ability to report claims that arise later from past legal services.
Extended reporting provisions vary by policy and by circumstance. Some apply following retirement, while others provide a short reporting window after termination. Understanding what reporting access is included, and under what conditions, is an important part of evaluating claims-made coverage.
With the only State Bar–approved Lawyers Professional Liability Insurance, coverage is underwritten by Arch Insurance Company and written on a claims-made and reported basis. The policy includes a limited post-termination reporting period, and additional extended reporting provisions may apply in specific situations, such as retirement, subject to the terms and conditions of the policy.
These features are intended to address the reality that professional liability claims may surface after an attorney has changed coverage or stopped practicing. As with all claims-made policies, the scope and duration of any extended reporting period are governed by the policy language itself.

Common Misunderstandings About Claims-Made Coverage
Claims-made and reported professional liability insurance is well established, yet several assumptions continue to create risk for attorneys.
1. Coverage applies simply because the legal work was performed while a policy was in force.
Under a claims-made and reported policy, that is not enough. The claim must also be first identified and reported during an active reporting period.
2. A short lapse in coverage has little impact.
Even a brief interruption can reset retroactive dates or eliminate the ability to report future claims tied to prior work, depending on the circumstances.
Some attorneys also assume that only formal lawsuits need to be reported. In practice, reporting obligations are broader and may be triggered by circumstances that could reasonably give rise to a claim, even if no demand has been made.
3. Extended reporting periods are sometimes misunderstood as extensions of the policy itself.
They do not provide coverage for new work and do not alter the retroactive date. They preserve reporting access for claims arising from past legal services, subject to the policy’s terms.
Why Continuity Matters and Where to Apply
Claims-made and reported professional liability insurance leaves little room for error when coverage is interrupted. Retroactive dates, reporting deadlines, and extended reporting provisions all depend on continuity. Once coverage lapses, exposure tied to prior legal work may not become apparent until years later.
For that reason, professional liability insurance decisions should be made deliberately. Renewals, changes in practice, retirement planning, and carrier transitions can all affect whether future claims tied to past matters remain insured.
The State Bar of California–sponsored Lawyers Professional Liability Insurance Program is structured with these considerations in mind. Coverage is written on a claims-made and reported basis and includes reporting provisions designed to reflect how professional liability claims develop over time. As with all professional liability insurance, the specific terms, conditions, and reporting options are governed by the policy.
