My impression is that paying child support is a judicial obligation, and whether it's moral or not comes down to how moral the ruling is, and whether or not the obliged payer neglects the payment for an immoral reason. To say it's by definition a moral obligation is to say that the court ruling defines morality, or that there are no valid reasons someone couldn't or shouldn't pay, and that'd be a bit silly, but I assume you're being hyperbolic.
