We are in Florida and our 17 year old wants to be emacipated to avoid moving with our family. She has lived with us since she was 7, and has had little to no contact with her natural mother who lives in Nebraska. We don't feel it is in her best interest to be emancipated as she is not mature, and has never had to support her self. She works but only part time while she goes to school and has never paid bills. Her mother has lost custody of all three of her children - what has to happen before her mother can sign the emancipation petition?
