You don’t know him or that he is fighting anything. She may also ask that he pay for child care, medical and transportation for all three kids, in which case he certainly should negotiate the $133. As the saying goes, you can always pay more but you can never pay less when it comes to child support.
Sounds like he’s only looking to what his legal obligation is. Again, if he would not acknowledge his parentage of one kid over $133 a month, even if it’s not his biological kid, Andy’s a dick.
When GreenTeen (not my bio-child) basically told me to go to Hell, it almost incited a divorce. But, I love my wife and will not abandon my younger children. As for Teen: She’s 17, an adult and not my problem. Another year of sponging off of me under my roof is (barely) tolerable. I haven’t spoken with her in about a year and in another several months she’ll be gone. Of course, this has REALLY backfired on her recently. My wife has spent much of the last two years in the hospital and now has lost her job to illness. Since she has no income, the only money Teen can get is whatever wifey can skim off of the budget.
She was about eight when I married, so not sure if that would change anything legally. Also, bio-dad has been occassionally involved with token phone calls and financial support, which would be more likely to change things.
But she’s still going to be in your life. It’s not like kids just disappear after they turn 18.
Your income will, however, be used to calculate how much financial aid she gets for college, and that will continue for the next six years, at least. There’s very little you or she can do to avoid that in most cases, though she can try to appeal it since you aren’t actually planning on supporting her. So if it makes you feel better, she may fall into the very small group of kids who really flat out can’t possibly afford to go to school.
