Event cancellation insurance can help reimburse you for the loss of nonrefundable down payments for expenses like catering, flowers, photography, entertainment or honeymoon travel if your event is canceled or postponed. You may also be protected if a paid vendor goes out of business before your event.

You should read your policy or speak with your insurance provider for details specific to any policy you might purchase, but other costs that may be covered include:

Event photographs. This coverage may reimburse you for payments made to a professional photographer if he doesn't show up for the job or loses or damages your images before giving you copies.
Special attire. Say your wedding dress is burned while being professionally pressed. This coverage may help pay to replace/repair your specialty clothing.
Special gifts. If a gift intended for your event is lost or damaged, this coverage may pay to repair or replace it. Monetary gifts may be covered up to a specific dollar limit.
Special jewelry. This coverage may help protect your wedding rings, quinceañera crown or other event-related jewelry if it's lost or damaged during the event. It may also offer protection for a specified period after the event.
Military deployment. If you must postpone or cancel your event because of a deployment — yours, or that of an immediate family member, active event participant or your officiant — event cancellation insurance may help reimburse you for lost fees.
Professional counseling. If your event's cancellation or rescheduling causes you enough distress that a medical doctor recommends counseling, this coverage may pay for those services.
