Reporting a situation that might become a claim, before it actually does.
A notice of circumstance lets you report a potential claim to your insurer during the current policy period. If it later becomes a formal claim, it's treated as if it was made when you first reported it—protecting you if you switch carriers.
A notice of circumstance allows you to report a situation that could potentially become a claim before anyone formally sues or demands payment. By reporting it during your current policy period, any future claim arising from that situation is treated as if it was made when you first reported it—preserving coverage even if you switch insurers or let the policy lapse.
File a notice of circumstance when you become aware of an error, incident, or dissatisfied client that could reasonably lead to a claim, but no formal claim has been made yet. This is especially important if you're nearing policy renewal, switching carriers, or closing your business. Reporting early protects you if the situation escalates after your policy ends.
A notice of claim reports an actual claim someone has made against you—a lawsuit, demand letter, or formal complaint. A notice of circumstance reports a potential claim that hasn't materialized yet but could in the future. Both trigger insurer notification duties, but a circumstance notice is preemptive while a claim notice responds to something already filed.
