Alcoholic DH, seperation/child access

[AnnonMouse]

Im finally saving to leave my DH after two years of being unhappy due to his drinking amongst other things.
There is DS1 (my StpS) and DS2 (both of ours)
Im wondering if anybody has gone through court and whats with access with an Alcoholic (functioning) father. DH thinks nothing of drink driving even eith DS1 in the car (no i do not condone this i have had many arguments but as with all AH their in denial and hes not mine to dictate) however i will not allow under any circumstances DS2 in the car.
If he gets access to DS2 i fear for his life while in his care. How does this stand up in court and what evidence is needed? I have no idea how this works, my heads messed up with it.
DS1 comes on weekends and he sees is his father drinking and drunk at night comatosed on the couch. I do not want this for DS2 i want a stable healthy life for him.

Have you told your stepson's mother that he is drink driving with her child in the car? Have you called the police on him when he is doing it?

@bluestich sorry i dont know how to direct reply to you. Yes she is aware of the situation same reasons she left him. And no authorities have been made aware... yet

Call the police the moment you know he's in the car drunk. They'll stop him, he'll get banned, the world will be a safer place for my sons as well as your sons.

Agree with PP report him the second he steps in the car drunk.

My ex husband once came to my house steaming drunk he had got out of a car, he had driven up my street, where young children playing outside, after a heated argument I grabbed his car keys off him, continuing to argue in my house, I called the police in front of him, told them what he had done, I think he thought I was messing, he was so drunk, Years ago within 10minutes police were in my house, BUT!!!!! because I had taken the keys off him, and he wasnt in the car, they couldnt arrest him, so they removed him from my house, but few days later he was caught drunk driving thankfully, because police put a marker on the car he was driving.
Call police give registration even do it on crime watch phone line, you have done all you can to stop him, threat's dont work with some people, so take action before he kills somone, I couldn't live with that on my conscience.

Does DS1’s mum know about the drunk driving?

The moment he gets in a car drunk, you call the police.
