I don't remember one in the UK.
You just buy things.
Quote: (Originally Posted by Unfair Contract Terms Act 1977 as amended)
2 Negligence liability
1 A person cannot by reference to any contract term or to a notice given to persons generally or to particular persons exclude or restrict his liability for death or personal injury resulting from negligence.
2 In the case of other loss or damage, a person cannot so exclude or restrict his liability for negligence except in so far as the term or notice satisfies the requirement of reasonableness.
3 Where a contract term or notice purports to exclude or restrict liability for negligence a person’s agreement to or awareness of it is not of itself to be taken as indicating his voluntary acceptance of any risk.
I look at disclaimers and as soon as I see it trying to get me to sign away my rights if they are negligent I know it's an illegal document and it's safe to sign. Even the fact that I read it and signed it isn't admissable. The law here is very clear that you can't sign away rights.
