I don't know about other states, but in IL if both parents are 'ok', joint custody is the norm, if both want it. This case was IL. My divorce was in IL. I have sole custody because the court decided that my ex would continue to cause harm to the children, he had very limited visitation for the first 6 years, until the youngest was 15. After that the judge allowed that the children could decide whether or not they wanted to go with him per arrangements, but needed to give him at least 24 hour notice if not visiting.
Sole custody is rare here.
My guess is that it is the norm elsewhere too. It just seems that it is so often the mother that gets custody with the father getting "visitation" rights. Coming from a man, that just does not seem fair to me.

It's been years, but from what I remember from when I went into file for divorce, they gave me a long sheet with all sorts of chores related to child care and asked how often each parent did what. I tried to give the ex as much time as seemed fair, though he was rarely home.
I think they figure out from that who will be 'primary' and such. Dunno for sure. But I know the ex also got one, the judge pulled it and said, "You mean you drive the kids to school, while you are at work? You travel at least 3 nights per week?" With that he tossed it to the side. My divorce took nearly 4 years and another 3 with the court having to keep adjusting or denying visitation.
Yeah, there were reasons he was ordered to undergo a psych evaluation, child development classes and I got sole custody.
