Yes, in most cases. A properly drafted waiver signed by an adult is enforceable in court for claims of ordinary negligence—but as with any legal matter, there are exceptions and caveats.
Enforceability can vary by state, especially when it comes to minors. Additionally, waivers are typically not enforceable in cases involving gross negligence. Gross negligence occurs when an organization demonstrates a severe, intentional, and reckless disregard for the safety and well-being of others. For example, if camp management ignores damage to the ropes course and a camper suffers a fall as a result, that would qualify as gross negligence.
For these reasons, it’s critical to have your waiver reviewed by a lawyer familiar with the specific laws in the state where your camp operates.
