I don't think you need to help out with the lawyer, that's your parents responsibility not yoursm however, you can talk to him and let him know that you love him and want him to be sober, happy and healthy. He is probably doing the drugs b/c he is so hurt inside from rejection of your parents. You handled it all well it sounds, but my guess is your brother isn't as strong as you are. Good luck to you and your baby. Glad to hear you know you don't have to choose the same path as the rest of your family.
As to the emotional blackmail that your father and brother insist on inflicting on you - don't fall for it. Nothing you say or do will ever change them, so don't waste your breath. It sounds like you have a nice dream of having a close, normal family relationship with your father now that you're an adult. Based on his behavior, that isn't going to happen. He doesn't ask about you and your baby because he doesn't care. Period. He's shown himself to be a very selfish person. Everything is about him.
You've already seen the harm he's done to you, your mother and your brother over the years. Do you really want your baby to be a part of that mess? Hold your head high above the sewage, and keep living the good life you've begun building for yourself.
