Can’t find husband??

I left my abusive husband he’s been evicted from the home and I can’t find him to divorce him or custody etc. How do I go about handling the custody thing? I was told he’d need to set up supervised visits etc due to abuse and i’m trying to get this stuff over with so my child and I can heal from that hell we went through and start a new life elsewhere Edit: I already have a lawyer nobody knows where he is to serve him anything
