I thought about asking that, but then after checking out NC law it appears that it would not make much difference in how the OP would proceed if he wanted to pursue paternity. The NC courts take the position that as between the OP and the mother, the child would be born out of wedlock and illegitimate if the OP was truly the father, so he proceeds the same way whether the mother was married to the other guy or not. The one thing that changes is the standard of proof the NC courts require. For a paternity case where the mother was not married to someone else when the child was born the standard is clear and convincing evidence. If she was married at the time the child was born, the standard would be beyond a reasonable doubt. That's one of the few times you'll see that standard applied to a noncriminal case. But with the advent of modern DNA testing, it's not that hard to meet either standard in the usual course of things.One question I haven't noticed that was asked in this thread. Was the mother married to the other guy before the child was born?
