So, you had a birthday part for your 10 year old at your house. The bounce house, which seemed like a genius idea at the time, suddenly blew away. Children were injured in the accident. You were then served with several different lawsuits from the parents of the injured children. This hypothetical highlights the necessity of waivers in today's society. Whether it's a neighborhood party with a bounce house or taking others' children to jump at "Trampoline World", parents must realize the liability they are opening themselves up to without a waiver drafted by an attorney for each child, signed by that child's parents. Alternatively, require the children's parents to attend so that the parents are responsible for the child. This will not negate all liability, but it will go a long way in reducing the risk.
