No, but this question raises many others, beginning with whether and how paternity was established. For example, the husband is presumed to be the father of any children conceived/born during the marriage, unless/until proven otherwise.
yes you can get sued for back child support. If the child is yours, you need to take responsibility until the child is 18.
You are liable for child support when your child spends more than half his/her time with another custodian. Typically this is worked out in family court. If you do not pay, you can be sued.
Until/unless you are determined to be the child's father, no.
No, usually support is only due when ordered by a court.
Yes, but you should not have to pay support for any period prior to your knowledge of the child.
Absolutely.
only if you made a baby, and if you made a baby you shouldn't have to be sued for child support, you should be giving it freely to feed and house your child, if you need someone else to order you to do the right thing, then you are what we call a deabeat dad, and not only can you be sued, but your drivers licence can be suspended or you can face jailtime for non-payment
yes see my profile
Only if the child has a severe disability.
You can always be sued. In such a situation, your wife will probably sue you for divorce, and the pregnant woman will probably sue you for child support.
Genetic testing does not require a urine specimen.
I'm not familiar with this waiver, but I'm sure that signing it does not exempt one from paying support.
