My fiancé has a 4 year old daughter and the mother ( a friend of mine ) told me that she was leaving the state with his daughter for a 2 week vacation but never told the father, does she have the right to do that with out his consent? Also, they are planning on going out of the country in the summer and she does not plan to tell him about that, so does she have the right to do that too? His name is on the girls birth certificate and his daughter has his last name as well!
