It seems unlikely that the child has your last name if you didn't sign something agreeing that you were the father. But, until there is a court order confirming that you have to pay child support, the child's name doesn't mean anything by iteself. If a court rules that you are the father, you will be required to pay child support. If you can convince a judge that you are not the father, you won't have to pay child support.
