Event liability coverage may help protect you if you're found responsible for property damage or an injury caused during your event, and many venues require you to have it. If the band you hired damages a wall with their gear, for example, this coverage may help pay for repairs. Some policies also cover incidents caused by your guests. So if someone gets a little wild on the dance floor and trips a waiter as he walks by, event liability coverage may help pay for medical expenses resulting from an injury.
