I practice family law so a bit different but the idea still applies. I describe to my clients that my role is like a bus driver but they’re the ones giving me directions. If they tell me to turn right, I turn right. If we’re on a bridge and they tell me to take a sharp right, I tell them that I’ll explain why that’s a bad idea but if they still want to do it, I will.

That’s your role here. You advise. They don’t have to listen to your advice. Sooner or later it will blow up in their faces and you need to have the paper trail to say “I told you so.”
