The one in which I mostly practice does, and I think it's a good idea.
Divorcing parents with minor children need to hear the following:
1) Children know they are 1/2 you and 1/2 your spouse, so don't bad-mouth the spouse in front of the children, because when you're bad-mouthing the spouse, you're bad-mouthing your children too ... and they know it. It hurts.
2) You and your spouse may not get along, but the kids are innocent here. Don't make them the victims of your dispute. Certainly don't use them as weapons against your spouse. To do so is horribly unjust and very cruel.
3) The kids get the family's primary residence. It's not you or your spouse who gets the house; it's the kids. The idea is to minimize the disruption of the children's lives, and they (plus whomever is the primary physical custodian of the children) should get the house ... because that's the right thing to do for the children.
4) You and your spouse must be able to communicate in a civil manner because you will be discussing your joint children (ideally) for the rest of your lives. You might as well start learning how to be civil to one another now.
And that's just off the top of my head, but these are things that divorcing parents with children need to hear, and, because the state is inherently invested in the institution of marriage, I see no problem mandating these kinds of courses.
