The time to ask for a DNA test is not after the divorce, he is precluded from doing this now. After signing the birth certificate you have 60 days to retract your acknowledgement of paternity and after that you are legally the father. If he had wanted a DNA test he would have to file a petition to disestablish paternity and have some evidence beyond believing his exwife had an affair, and should have done that prior to the divorce final hearing. My guess is that it is to late now.
