In re K.B.E
In In re K.B.E., 740 P.2d 292 (Utah Ct. App. 1987) the unwed father registered on the afternoon of the same day of his child's birth, but his registration was preempted by the actions of the mother who filed an adoption petition that morning.
The court explained that "to deprive both the unwed father and the child of the possible benefits of their relationship simply because the unwed father filed his notice just a few hours after the mother filed her petition for adoption . . . flies in the face of fundamental fairness and due process."
