Adopting niece from out of state
I want to adopt my 2 year old niece but she is living in Missouri and my fiancé and I live in Louisiana because of the military with our 2 boys- ages, 4 and 18 months. My sister and her boyfriend do not have a stable home environment (living at peoples houses or in the car) and my 2 year old niece lives with my sisters boysfriends aunt and uncle. The boyfriends name is on the birth certificate but is not the biological father and I plan to have a dna test done! The aunt and uncle talked my sister into signing over temporary rights to my niece to them. The "aunt" is on the road half the time driving trucks (and taking my niece with her which I believe is illegal) and the "uncle" has lung cancer and has had a heart attack before and they are both way to old to be raising a little girl. The temporary rights are over in June and they plan on adopting my niece. My sisters boyfriend has been fired from his job for smoking week and smoked weed in front of my 12 year old sister just the other day! My sister and the boyfriend have both been in jail numerous times for domestic violence with each other. What are my rights in this situation and do my fiancé and I have a solid case to win?
