HOW DO YOU GET HIM TO PAY CHILD SUPPORT?

How many people in today's times have a son-in-law who is a loser? I bet there is a lot of them out there.
My daughter is raising three kids ages 5, 10 and 12 by herself, no doubt there are many other women doing the same thing. She was just granted a divorce and the first child support payment was due on the first of November. Guess what? No payment was made. His excuse is that he does no have a job and only makes $1600.00 a month from unemployment. The payment for child support is $378.00 a month and he can't make it. The Attorney Generals office just says, turn him in each time he doesn't pay and we will keep a tab of back child support. Meanwhile he is living at home pays no rent and parties on weekends.
Before the divorce he asked to see the kids. The kids would be all excited and he would not show up or would call and cancel.
He can't get a job because I don't think he can pass the drug test. He works on oil rigs.
I guess there are more losers out there than good guys.
