Sorry buddy! in other words no... tough luck
If the child is definitely yours, then certainly.
No, you are only liable from the date you are notified of the application.
If the child is biologically yours you cannot get out of child support. Why would you not want to take care of your child? And if the isn't yours i think u should still treat it like it was yours!!
Yes, but you need to file a child in need of care motion.
If you have signed the birth certificate, then yes, that child is considered yours to support and claim. In some states, you can pay for that child if you provided support or let that child take on your name.
If you have paid child support and it turns out the child is not yours you are entitled to sue for repayment of the money.
No, you cannot get money back that you paid in child support. There may be circumstances where you could sue a person for some of that money back if you found out the child was not yours.
Only if she has a court order
Yes and no. see links below
Ethically, if the child is yours then you pay support. The circumstances are irrelevant.
You can stop child support payments on the grounds that the child is not your biological child only if you did not know that when you agreed to the support, and if a Court approves your request to stop.
