The child know is 4 years old and she got divorce when he was 2 . no one is wrriting as tje child father in the birth certificate . do i need to pay / dows it change to the amount of the child support that the child was born at the time she was married ?

thank you

The mother will need to establish that you are father through a paternity test before you can be ordered to pay support. The fact that she was married at the time the child was conceived is irrelevant if you are proven to be the father.
