Thank you for your follow-up, Holly. My apologies on the delay, I went offline to get some rest.
To respond directly, I would first suggest you try to obtain a copy of the current birth certificate. If someone is listed there, then it is THEIR child, not your husband's, because legally the other person was listed far longer and your husband was even unaware of the child being his. Even if the paternity test came back with probability, what governs is who is listed in the birth certificate as the father because that is the person who is considered the lawful parent, not who is biologically related (in some ways consider this as akin to a situation with an adoption).
Second and more importantly, file a petition denying both the petition for paternity by pointing to notice. If he has been the child's father for so long but was never notified, he is no longer responsible because the other parent only has a limited time during which to make her claim. It is also impossible fo rher to legitimately demand 'past' support if your spouse was unaware or not listed on the certificate because even if all goes badly and he is made the father by court order, his requirements to pay kick in from the DATE of court order, not from a past date. I would very strongly suggest you invest into an attorney in this case, this is a situation that is beatable for your spouse.
