Your mom is completely wrong here. This is a matter between her and your dad. If he is not paying the minimal support dictated by the court, then she can contact her case worker and see what steps she needs to take to get him to pay the arrears. If the money she wants is above and beyond what is spelled out in the divorce/child support papers, then too darn bad for her, because he doesn't have to pay.

I am a step-mother of three kids and their mother is supposed to pay child support... we never see it. Their mother is over $20,000 behind in payments. As your mom how she'd feel if your dad never paid. She might appreciate what he does do.

The problem with reporting his delinquency to CS (If he is delinquent, rather than habitually late) is that they can toss him in jail. If he's in jail, then she gets NO money.

She can opt to take him back to court - but she then runs the risk of them re-evaluating the amount he owes and could determine that his financial situation has changed and make him pay less.

Also, in most states, its a law that a CS case can be re-evaluated every 3 or 4 years to determine if the amount paid monthly is appropriate for the parent on both sides.

I'm sorry that you are being thrown into the middle of this. Good luck!
