As an addict talking, I'd sign your 'contract',while laughing about it in my head. As a guy with a bit over a year sober, I wouldn't sign or agree to any contract that does not pay me. Kinda like the addict me,but sober. It's a piece of, non legal binding, paper and that's it. To me it seems pointless. What if he 'voids' the contract? Is there some 'punishment' written on it that he's not already been told a bunch of times? I think codies have a hard time accepting that the situation is out of our control. No contract is going put you in control of his problem.
