What does Oklahoma state law say if a married woman has an affair and gets pregnant by the man whom she is having an affair with what rights does that man get?

Answer 1

I don't know Oklahoma law, but I suspect that her husband is presumed to be the child's father unless/until there's a court order to the contrary. Such order would typically be based on an acknowledgment of paternity or genetic testing. After that happens, you can talk about "rights," including the right to pay child support.
