Due to the culture of liability, skydiving age limits differ in each country. Suits are widespread in the United States, considered a litigious society. In the United States, 18-year-olds are considered mature enough to understand the consequences of their actions and, as a result, to understand what they are signing when completing legal paperwork releasing skydiving centers and skydiving equipment manufacturers from liability regardless of negligence. In other nations with less litigious societies, it is more frequent to see people under the age of 18 participate because the question of parental consent has been proven in court.
