A Screwed Up Childhood in the making

From Plastic.com

When Christy Wizner of Heppner, Oregon gave birth to a baby girl back in April of 2004, the father, Chad Doherty, said he wanted to be a part of his daughter's life even though he and Christy weren't going to get married. He assumed that the girl's last name would naturally be Doherty. He assumed wrong. Christy, who had divorced but kept the last name Wizner, had three other children all with the last name Wizner. It was her desire that her youngest child have the same surname as her older siblings. Doherty disagreed and thus began a two year legal squabble.

I link the poster wicked_sprite summed it up concisely

Seriously, you are born and your parents spend years fighting over your last name in court. Just wait for the spank-or-not-to-spank battle. This child is hosed.
