That would depend on the content of the waiver. And Florida law does not favor waivers or what we call exculpatory clauses, where people sign in advance saying they’re going to release somebody from liability if they get hurt doing something after they’ve signed the document.
But they can be difficult to deal with. If they’re properly written, they can be effective. If they’re not properly written and a lawyer has dealt with this issue before, he can defeat the waiver of liability. So it just depends on a) the content of that waiver and b) the experience of your lawyer.
