I agree that the parents shouldn't be forced to pay her tuition.
But, I just explained this on another thread: Here in NJ, when parents divorce, they are required to pay their children's college tuition.
For the record, I don't agree with the law. I didn't write the law. I'm just explaining that this ruling is very common here.
The only thing unusual about this case is that the daughter is the one bringing her parents to court. (Usually one parent brings the other to court.)
