Wedding cancellation insurance protects you from financial loss if you need to postpone or cancel your wedding. Cancellation insurance can reimburse you for lost deposits due to factors like fires, floods, severe weather, accidents, injuries, unemployment, military deployment, vendor now-shows, vendor bankruptcies, etc. Liability insurance protects you from being held financially liable for property damage, medical expenses for bodily injury or an alcohol-related accident. For weddings, the insurance provides three full days of coverage, including your rehearsal dinner, wedding day, and post-wedding brunch.
