Ok my son is 5 years old he has never seen or met his sperm donor. He is 10 years older than I and don't care about the child we have together. I received 600 dollars on child support for the first time it was income tax when I checked again it was gone. When I called to find out what happened they informed me that he was married and filed joint on his return and had to wait 6 months to get it. So if he is married his income has changed. So could they use his wife's income also and up the child support we love in Oklahoma
