It's been awhile since I was current on the law surrounding paternity testing, which I'm pretty sure used to be illegal without the mother's consent. I found this on the website of a company that does DNA testing: "As the mother’s DNA sample is not required for an AlphaBiolabs peace of mind paternity test, her consent/permission is not needed to perform the test, provided the potential father has parental responsibility for the child being tested (if the child is under 16-years-old)."
I don't know what the legal ramifications of the test results would be, though. Some states will order child support from anyone who has ever assumed a significant parental role (even grandparents who helped raise a child for a period of time or boyfriends of a single mother) and I'm pretty sure most states consider any husband the presumptive father.
