When you go to court take his death certificate with you or his death notice from the Ponca City Newspaper. The judges here tend to agree with the moms and it doesn't matter what documentation you have but a death certificate should take care of that issue.
As for the other, he will have to pay back child support from teh time the child was born until he turned 18 or stopped going to school and living at home with the mom, such as a college student who lives at home and still getting child support at 21....
Go to the bank building on 3rd or 4th and Grand and go upstairs to the child support enforcement office and have him ask to talk to his case worker. You might not be allowed to go in the room but might get to go in too. There is also a phone number to call for child enforcement, it's an 800 number and he can get it from DHS on Grand. it gives you the run around but eventually the same worker he would see in the office should call him back.
There are many ways they get the back support. Income taxes are the biggest way in lump sum. If you file with him you'll need to file "Injured souse", that way all of your income will be exempt from holding to give to the child support. They put a block on the refund and to get any of it released you have to file the injured spouse withing a few months of filing or they give the child the entire amount at once. They hold it for aobut 4 - 6 months and then it's disbursed. If you file injured spouse int he correct time frame they decide the details and let you know and then you get a check for the amount they will let you collect.
They will try and get his employer to hold out the full amount of child support each month before taxes. I get child support every Tuesday, that dad gets paid every Friday and by the time it's processed I get it on Tuesday. If there is a 5th week I don't get anything unless he owes back child supprt. They only hold out the amount court ordered...if it's $400 a month, and the dad gets paid every week, they would hold $100 per week and on a month of 5 Fridays they would not hold anything out that 5th week.
Anyway, child support is fun and challenging for everyone. Talk to the horses mouth in the child supprt enforcement office on grand. Or go talk to an attorney if you can find one that will do a 30 minute free consultation. BEFORE COURT!!!
One father does owe back support and the other does not, my daughter has never paid a penny so if she ever gets off the streets and gets a job she'll never see a cent of her returns for years and they will hold out the entire amount every month.
