Understanding Claims-Made vs. Occurrence Policies: What Design Professionals Need to Know
When it comes to liability insurance, one of the most important distinctions for design professionals is the difference between occurrence and claims-made policy forms. Understanding how each works is critical to ensuring proper protection—and avoiding costly gaps in coverage.
Occurrence Policies: Coverage Based on When the Event Happens
Most general liability policies are written on an occurrence basis. With this type of policy, coverage is triggered by the date the incident occurs, regardless of when the claim is actually filed.
This means:
- If an incident happens while your policy is active, you are covered—even if the claim is filed years later.
- The policy in effect at the time of the event responds to the claim.
For many types of risk, this structure works well because incidents and resulting claims tend to occur relatively close together in time.
Claims-Made Policies: Coverage Based on When the Claim is Filed
Professional liability risks—especially for architects, engineers, and other design professionals—operate very differently. Claims often arise years after the alleged error or omission occurs.
To address this delayed exposure, insurers developed claims-made policies. Under this structure, coverage is triggered not by when the work was performed, but by when the claim is made.
Today, virtually all professional liability policies for design professionals are written on a claims-made basis.
The Three Requirements for Claims-Made Coverage
For a claim to be covered under a claims-made policy, three key conditions must be met:
- Active Policy at Time of Claim
The policy must be in force when the claim is made. - Retroactive (Prior Acts) Date
The policy must include a retroactive date that goes back far enough to cover the work that gave rise to the claim. - Timely Reporting
The claim must be reported to the insurer within the policy period—or within a short grace period (typically 30–60 days) after the policy ends.
Failure to meet any one of these conditions can result in a denial of coverage.
Why This Matters for Design Professionals
Because claims-made coverage depends on continuous protection and proper reporting, changes in your business can create significant risk if not handled carefully. This includes:
- Mergers and acquisitions
- Firm splits or restructuring
- Retirement or business closure
In these situations, maintaining continuity of coverage—often through tail coverage or careful policy structuring—is essential. Working closely with a knowledgeable insurance advisor is critical to navigating these transitions.
What Exactly Is a “Claim”?
The definition of a claim can vary significantly between policies, and misunderstanding it can lead to serious coverage issues.
A claim is typically defined as:
- A demand for money or services
- A lawsuit or arbitration proceeding
However, some policies go further and may include:
- Written demands only (in some cases)
- Oral demands (in others)
- Awareness of circumstances that could reasonably lead to a claim
This last point is especially important. Some policies require you to report potential claims—even before a formal demand is made.
The Risk of Late Reporting
Failing to recognize what constitutes a claim—or delaying reporting—can have serious consequences. Late reporting may result in:
- Denied coverage
- Uninsured defense costs
- Significant out-of-pocket liability
Final Thoughts
Claims-made policies are designed to address the long-tail nature of professional liability risks, but they require a higher level of awareness and diligence from the insured.
Design professionals should:
- Fully understand their policy definitions and triggers
- Maintain continuous coverage
- Report claims (and potential claims) promptly
- Seek expert guidance during any business transition
A proactive approach can make the difference between a protected firm and an uncovered exposure.
