Many gyms, recreational, and sporting organizations will require participants to sign a waiver of liability prior to participating in an activity. In some cases, this will limit the plaintiff’s ability to bring a suit, but this is not always the case, and you should always speak with an attorney to determine whether you have a viable personal injury suit in spite of a waiver. Waivers must be very explicit in what they entail in order to be effective, and courts will construe the waiver in favor of the plaintiff when possible. Furthermore, where the injurious conduct was reckless or intentional, a waiver will be ineffective.
