Is it true that I have to hire a lawyer to get visitation in writing that they will not do it without one?

My wife and I separated some time ago. She has a boyfriend living with her and my children and she has a baby by him since we separated. Is she able to keep my 2 daughters from me even though I pay my child support. She threatens me with "you won’t see your daughters" or "I don’t think you need to see them" whenever she gets upset that I will not give her any "gift" money on the side. We have no visitation set up by court and Lorain County Ohio told me that I have to hire a lawyer to get visitation in writing that they will not do it without one. Can this be true? I just want to see my daughters...can anyone help me?
