I recommend that you get a paternity test done to see if you are the father or not. If it comes out negative, you have your document. If it comes out positive, then you are financially responsible for the child and no one piece of paper is going to relieve you of that responsibility. However, if the newborn is adopted by another, the adopting parent becomes financially responsible and generally you are relieved of that obligation and out of the picture. Be aware that while you may make arrangements to pay for the support of the child, if you are the father and the mother ends up on aid, the state has a right to seek reimbursement from you, of that state aid money.

If you're the Daddy, you're on the hook to contributing to the support of your child.
The way to have prevented problems in your happy marriage was not to have been doing anything which would result in your having another child.
If GF files an action for child support, the court will, if you request it, order DNA testing. If it shows that you're not Daddy, you're off the hook; if you are Daddy, you're on the hook for child support unless she gets married AND her new husband adopts your child.
I tend to agree with counsel. Your best bet is to prove that you are not the father via DNA paternity test. Until the court orders you to pay support, you do not have to pay her a dime. To prevent this in the future, do not produce another child that you do not want to take care of.
