There can be perfectly legitimate reasons for being behind 10K in CC debt, custody battle, emergency, etc. There can be perfectly good reasons for being behind 10K in CS, accident, unemployment, etc. In all cases the payer should be responsiible enough to make the proper legal notifications but even that won't change the reality of the situation.

Speaking of reality, any CS who would let their child go without basic necessities (as you stated) because somebody else wasn't paying something should not be a CS. Your agenda is typically clear, use threats of jail and child's sufferring as a tool for $ from X. No surprise finding you here. Despicable.
