Her mother/my sister thought it would be best if raised her. My husband and I been caring for her since she was 2 and she is currently 5, almost 6. The father states he'd like to be active in her life, though he doesn't visit her at all, very rarely calls, and does not offer any financial support. The father is now in the army and states he'd like to be more of a father to her. However, in Sept/Oct he's called her a handful of times, told her he'd visit (during xmas time), and we haven't heard from him since. We take care for my niece 100% w/out any assistance from either of her parents, though my sister/her mother is currently residing w/me. My sister is willing to relinquish her rights as her mother. Her dad is not so willing, though he did not sign her birth certificate, can you help?

Guardianship is a pretty extraordinary remedy, especiallly where the birth parents are still alive. You would file a petition with the assent of the mother. However, you will also be required to give notice to the father, and ultimately a hearing will be conducted in which all parties will have the opportunity to present their point of view. It is likely that the court will appoint a "guardian ad litem", who will investigate all of the facts and circumstances in the girl's life, and then make a reccomendation to the court as to what is in the best interest of the child.
The next complication is that if the father is now enlisted in active duty in the military, under the Servicemembers' Civil Relief Act (SCRA) he may be entitled to a stay of any proceedings until such time as his assignments will allow him to participate.
I highly reccomend that you get a consultation with an experienced probate attorney in the area where the girl lives.
