The intergroup should have their liability insurance agent add events to the definition of general intergroup operations. Therefore, the event(s) would be covered under their general liability policy.
The intergroup can contact the insurer of the event location and request to be placed on the location’s policy as an additional insured.
Separate event insurance can be purchased. Costs will vary significantly, depending on the length of the event, number of attendees, and type of event. Contact a business insurance agent and request event insurance.
Intergroups requiring liability insurance to cover affiliated meetings can contact a local business insurance agent and request information and pricing for liability insurance coverage for the intergroup with certificated policies for its affiliated OA meeting groups.
