I'm fairly sure it's called a limited liability clause. They are literally everywhere. Ski resorts, adventure parks, paintball facilities, and even pools. There are many ways these are worded. Keep an eye out anytime you partake in a service/activity where there is a whiff of danger.

Edit: In terms of asset protection (losing houses and retirement) an LLC, GmbH, or Pty. Ltd. will limit loses to assets owned by the company.

Again talk to a lawyer.
