It has not changed in twenty years. I was told by a judge in 1989 that I was morally obligated to pay for Catholic School. I was going to pay it anyway but since when is heir a mixture of church and State ?
This really isn't a mixture of church and state. The thing about private school is that if it's "in the best interest of the child," then the court may order one or both of the parents to pay for private school. "Best interest" is broad, and could mean continuity of education (ie, if the kid was in school before the divorce), or if the child has "special needs" (again, very broad).
