You can write any "law" you like and have people sign it. This is very common with leases beween tenent and landloard btw. It is another thing about them being legal whatsoever and they frequently arent. Just because a lease has been signed and certain things in it agreed to by the signer doesn't makes it any more legal.
I'll give you another real good example. Next time you get a credit card offer look at the terms in tiny letters in the back of the form. It says that by agreeing to have the credit card you give up the right to declare bankruptcy and agree to pay all the credit card companies bills if you do. All of this is totally illegal but is still allowed to be included under the law. Just by signing that form doesn't make you libel either....
