A liability "waiver"...
isn't worth any more than the paper it's written on. I'm routinely surprised at how many individuals and business that think they are.
A contact signed under duress isn't valid anywhere I'm aware of and you simply can't sign away liability.
Ask an attorney if having a waiver of liability in place would stop them from suing an individual or a company for negligence.
It could happen any time
It could happen
or sunshine, love, salvation
It could you know, that's why we wake
and look out
No guarantees in this life but some bonuses
like morning, like noon, like evening...
