No, I said the child was UNDERage. I remember reading about some gal who married a wealthy Saudi, a baby came along and the marriage went south. Papa took the little one back to Saudi Arabia, and Saudi Arabia said, "Sorry, we will not just hand the kid over because your lawyer says so." Legal nightmare. How it came out, I don't know.
Prior whatever country they are in, the laws apply.
Which is pretty much what happens now.
