What exactly happens at a child support enforcement hearing?

There is a child support hearing being held next week due to my son's father's nonpayment. I was wondering what happens at those...I'm guessing they pretty much say "you have until such-and-such date to pay $xxx.xx or you go to jail"? A little background, if it makes a difference...my son's father was discharged from the Marines for a permanent injury (ankle injury from playing football in Japan--go figure) so he has been getting unemployment since January. The last child support pmt that was received was at the beginning of May, and when I call the domestic relations office they say that they have no employment on record. The last income they have on file is his unemployment though and from I have been told he is still receiving unemployment (he can afford to pay rent, buy beer every week and go golfing 3x a week without a job so I know he's getting money somewhere). His dad said that he is eligible for unemployment until the VA tells him he can work and signs off on him or whatever. I called to see if I can come to the hearing but they pretty much said no...it's for him only. What should I expect to come out of this?

Some FYI--I do not WANT him to go to jail...that may have sounded bad in my question. Our son (who is almost 6 years old) is at his house 4 days a week for a few hours until I get off work and he is "active" in his son's life, so I would rather him not go to jail. Just wanted to make that clear.

man, this brings back bad memories...at the first hearing i went to with my then ex husband, we had to bring in proof of earnings, taxes, etc...there was a mediator..this was in NY..he asked a bit about our background..we had been sent a bunch of papers about our expenses and had to provide the mediator with them....i dont remember if an amount was determined at that time or later on..but that was about it..lately my ex is now collecting SS disability and child support has "garnished" that b/c my ex doesnt pay..my daughter is now 20 and i can count on both hands how many times she has received support..not sure if that helps...

heres a bit more info:

During the process of establishing paternity and/or child support for your child, you may be required to attend a hearing and testify to a variety of questions. A hearing will be conducted by the department or a judge in court.

The type of questions you will be asked depends on the type of hearing being held. For example: If legal paternity has not been established, you will be asked questions, which may include very specific and personal information regarding the circumstances that led to conception. If the hearing also involves or pertains to some issue of financial support for the child, you will be asked a number of questions which will help determine the amount of child support to be paid. You may be asked questions pertaining to your marital status, the number of children involved in this case, employment, income, living expenses and insurance coverage.

The answer to that question I'd say is, is is fair that the child isn't getting any money or money support from his dad.. I agree its great that the dad has something to do for him, sadly eunff, even though you don't want this man to go to jail, he's slacking on the repsonisibilty of his own child from day to day month to month.. Does he pay any thing for like clothes food?
Thats where your getting it all confused.. And in the state that I am, if the parent don't pay child support, they take the chance of loosing the driver's liences, and then if they work, they loose there jail which winds them up in jail.. To me thats a simple enuff...
And he's not reporting that he's getting unemployment? have you gone to court about child support..
does he buy stuff for the child when he is over at his dad's house???
Still costs, anyway you look at it..
best of luck!
