General liability insurance comes in two policy types: occurrence-based, the standard option, and claims-made, which is rare and sometimes not offered. The distinction comes down to timing.
- Occurrence-based policies cover events that take place during the policy period, even when a claim arrives later. When someone slips at a business in 2024, coverage applies even if the lawsuit comes in 2027 after a switch to a different insurer.
- Claims-based policies cover claims filed while the policy is active, but only for incidents that occurred on or after the policy's retroactive date. When an insurer is switched or coverage is dropped, older incidents may no longer be protected unless extended reporting coverage is added.
Both types use two limits: a per-occurrence limit that caps what the policy pays for a single incident and an aggregate limit that caps total payouts for the policy period (typically one year). Most coverage parts use these same limits, but medical payments (MedPay) and products and completed operations coverage are configured separately.
Most general liability policies do not carry a deductible. When one is present (common for certain claims such as third-party property damage), that amount is paid out of pocket, and the insurer covers the remainder up to the policy limits.
