My children's father has not had anything to do with them since they were babies. He never filled out the paternity affidavit in AZ, so he isn't even on their birth certificates. They are 16 and 17, and the only support he has ever provided is his SS disability benefits. He told me that he is about to raise his new girlfriend's unborn "rape baby" (his words) as his own. I take that to mean he's going to to fraudulently swear out a paternity affidavit, putting his name on this child's birth certificate. I fear that he will next file for SS dependent benefits for him, which will cause my daughters' payments to decrease dramatically. He's never gotten them presents for Xmas or B-days. SS is all he's ever contributed, and that's passively. If he carries out this fraud, do I have any recourse?
