After child support is imposed, anyone ever been able to bring it to a premature end? My ex is greatly desiring to buy me out of an expensive house, and I wondered if I dangled terminate child support for a big discount off what she owes me, is possible? I see in my state there's a form you can submit to change child support. Maybe she'd like to sign such form, we'll submit it together, then I basically discount that amount from what SHE owes ME. No idea if she'll take that, but I wonder if anyone changed child support after being saddled with it.
