For many events the possibility of adding a cancellation insurance to your ticket is offered.
With a cancellation insurance you have the possibility to ask a refund for your tickets in case of: serious illness, severe accident-related injury or death of an insured party or of a relative by blood and/or affinity in the first or second degree; complications during pregnancy; severe damage to property; irretrievable breakdown of the insured party’s marriage; theft, embezzlement or loss of, or total loss damage to, the vehicle to be used for the trip to the event.
See Insurance Product Information Document (IPID) and the FAQ for more information.
