This case actually reminds me of a similar case some years ago. I can't remember all the details clearly, but I do remember that the mother had signed adoption papers and the father was unaware of the adoption. The father sued for custody of his child, which was eventually granted, even though the child had lived with the adoptive parents since very shortly after his birth. If that case is any indication, then I believe the father in this particular case will eventually be awarded custody. I don't believe it should matter that the father in this case is Cuban, but, given the Elian Gonzales mess, it probably will.
