Do you want to thank friends or volunteers in a special way by having a large event? If you host your gathering at a commercial or public venue (such as a community center), special-event insurance can protect you from big liability losses.
An event policy is short-term coverage that protects the host from liability losses, such as damage to the venue and injury to guests. Some venues require party hosts to carry event insurance and name that provider as an additional insured, which protects that establishment from financial losses if it is listed on a personal injury lawsuit against you.
If you will offer alcohol at your gathering, having a host liquor liability policy is a good idea. This helps if someone over-imbibes and causes harm. And if you have vendors involved—games, music, caterers—make sure their insurance dovetails with yours. Your agent can help you sort that out.
