Is an occurrence policy better than a claims-made policy?

Neither is inherently better. Occurrence coverage is broader for long-tail injury claims and needs no tail, but it is not available for most professional liability exposures, which are written claims-made.

Do I need tail coverage with an occurrence policy?

No. Tail coverage exists to extend the reporting period of a claims-made policy, and an occurrence policy is already triggered by the event date, so there is no reporting period to extend.

What happens if a claim is reported after my occurrence policy ends?

The policy that was in force when the event happened responds, subject to its terms and limits. Report the claim to that carrier and keep prior declaration pages so the correct policy can be identified.

Which policy responds if I had several occurrence policies over the years?

The one in force on the date of the occurrence. If the event spans several dates, carriers may allocate responsibility, which is one reason complete coverage history matters.

What is an occurrence policy?

Short answer

An occurrence policy responds to an event that happened during the policy period, no matter when the claim is reported later. General liability, property, and most personal lines are written this way, which means the coverage stays with the policy year rather than with the date of the claim.

How an occurrence policy works

Coverage attaches to the date of the event, not the date of the claim. If a client is injured at your office in 2024 and sues in 2027, the 2024 general liability policy responds, even if you have changed carriers twice since. That is why old occurrence policies matter when a claim surfaces years later.

Occurrence vs. claims-made

Occurrence: triggered by when the event happened, so a long tail is built in
Claims-made: triggered by when the claim is reported, subject to a retroactive date
Occurrence policies have no retroactive date and no tail coverage to buy
Claims-made policies are the standard for professional liability, tech E&O, cyber, and EPLI

Where occurrence policies are used

General liability and products-completed operations
Commercial property and business income coverage
Commercial auto liability
Homeowners, renters, and personal auto policies

Why it matters when you switch carriers

If a claim arrives after an occurrence policy has expired, report it to the carrier that insured the event date, not your current carrier. Keep old policy numbers and declaration pages, because the responding policy may be several years old and the current carrier has no obligation to defend it.
