I have a not so distant instance of incorrect information being put on a birth registration. It's too recent to name names, but a teenage girl, living at home, with her parents and other siblings, gave birth, and, presumably to save any embarrassment to the rest of the family, she specified her rather unusual middle name as the mother's maiden name.
That strikes me as probably being illegal, but what sort of penalty could she have faced?
I will probably buy a copy of the birth certificate, just to see if it gives any information about the father, but I think that is unlikely.
