Release of liability

[Joe Detlefsen]

Hello All! 

I'm working with a buddy who buys raw land and builds new construction homes on them. A question popped up today and I wanted to come to you guys about it. I tried looking for a form on BiggerPockets which would state that all subcontractors have been given a safety meeting and with their signature, they were no longer allowed to sue the company if something were to happen. Is there such a thing? If so, where can I find it? If there is another way to make this happen, please let me know. 

Thank you everyone!
