Yes, an order of non-paternity typically indicates that you are not the biological parent
and your obligation to pay support is terminated, with no further payments being required.
So if you are being sought for payment of support on this child, you could normally use the order you obtained to avoid payment.
If a state agency is seeking payment, you would typically need to file suit against them seeking a declaration from the court that you do not owe any further support for the child since you are not the biological father and the court has ordered that you do not owe support, but you will need to obtain a copy of that court order.
