A big problem I see is that cases vary so widely that rigidly applying a legal prescription can lead to really bad outcomes. That's one reason I think it's important to listen to the kids, especially if they are freaking out. Maybe they're over-reacting. Or maybe not.
There is a saying among the legal fraternity;
"hard cases make bad law". I think it originated with the same judge who instigated the
"Clear and Present Danger test" that limits the US Constitution's First Amendment right to free speech.
I think there are too many hard-arses posting in this thread who;
a. have never seen first hand what can happen to kids in a divorce and in dysfunctional families.
b. think that these cases are all
"one size fits all", and don't understand the consequences to the children in broken families of blindly applying the same criteria unilaterally,
c. think that the Law is a absolute and everyone should march to the tune of the courts.
Courts are fallible, especially in family law. They get a lot of decisions wrong, and its generally the children who pay the price for those errors years down the line.
IMO, what the children want should carry a lot more weight than it does, and that weight should increase with their age. At age 9, perhaps the Judge might be better placed to decide, but by the time a child reaches 14 or 15 they know which parent they want to live with.
I have seen what happens when an older child is forced against their will to live with one parent or the other. It frequently ends in disaster and emotional trauma for the child.
There was a case in England recently where a 12 year old by was forced to life with a father he despised. Eventually, the court order was overturned in the best interested of the boy, because he refused to eat, and refused to speak to him.
You have to wonder why they just didn't listen to the boy in the first place?
