Understanding the ‘Claims-Made’ Basis in Professional Indemnity Policies


In complex legal transactions, professional oversights or procedural errors sometimes take months or even years to come to light. To maintain robust financial security, understanding how the claims-made basis operates in professional indemnity policies is essential for both practice firms and their clients.
Unlike standard property or personal accident coverage, the handling of professional claims for lawyers and notaries depends on precise legal timelines established for each file.

📌 The Core Mechanism of the Claims-Made Basis
The “claims-made” indemnity mechanism is a foundational principle of professional indemnity policies. Under standard policy wordings and regulatory guidelines, third-party compensation demands alleging legal liability against the Insured are covered by the specific policy in effect when that claim is first made in writing.
This means the insurer does not look solely at the date when the negligent act occurred; it directly evaluates the date when the formal written claim was first brought against the practice organization.

⚖️ Two Vital Conditions for Policy Admissibility
For an incident to be accepted and processed under a claims-made basis, the claim file must generally satisfy two cumulative requirements under the agreed terms:
- Timing of the wrongful act: The negligent act, error, or omission (or alleged act) must have occurred during the policy period, or on or after the retroactive date specified on the Certificate of Insurance.
- Timing of the claim: The third-party claim for compensation must be first asserted in writing against the Insured during the active policy period.
If the error occurred before the retroactive date, or if the claim is served after the policy has expired without a valid reporting extension agreement, the resulting loss will fall outside the insurer’s liability.
🔍 Serial Claims and the 30-Day Notification Extension Rule
In practice, a single mistake can cause sequential losses or prompt multiple parties to file separate actions. Policy rules address continuity and notice windows through specific provisions:
The Concept of Serial Claims
All claims involving various consequential losses that stem from a single negligent act or error are aggregated and treated as a single claim. Where two or more acts arise from the same originating cause or source and share continuous legal and financial grounds, they are likewise treated as one single act.
In such instances, the date of loss for the entire series of claims is formally established as the date when the very first written claim within that chain was lodged against the Insured.
The 30-Day Event Notification Window
Under standard policy provisions, upon the occurrence of any event or circumstance that could reasonably give rise to a future claim, the Insured must provide prompt written notification to the insurer.
If written notification of the circumstance is submitted no later than 30 days after policy expiration, any formal claim arising from that notified event established within 06 months of the policy’s expiry date will be considered as having been made during the active policy term.
📋 Comparing Primary Indemnity Principles
To highlight the structural difference, consider this straightforward comparison:
| Comparison Criteria | Claims-Made Basis | Occurrence Basis |
|---|---|---|
| Triggering Event | First formal written claim served during the active policy period | Date on which the actual act, incident, or physical loss occurred |
| Timeline Dependency | Tied to the retroactive date and continuous, active policy renewal | Tied strictly to whichever policy was active when the event took place |
| Common Usage | Standard for legal, notary, and professional liability policies | Standard for personal accident, motor vehicle, and cargo transit insurance |
For legal practices, maintaining uninterrupted policy continuity from year to year is critical.
