I find out my fiance is paying child support for almost 9 years now for two kids I didn't even know about. We talked about it and he tells me he doesn't even know if the kids are his. We've searched on line to read about dna and stop pay on child support . if he was to get a dna and test come back saying he's not the father can he stop paying child support? Hes never spent time or met the kids. And is it to late to get the dna test done if the mother of the kids say no to the test? Or does she have to do it if my fiance wanted to do it? oh and I forgot to mention he did sign the birth certificate for the first child but not the second.
