My question involves a child custody case from the State of: Missouri.
I'm 21 yrs old and am in the military. I'm currently stationed in the dc Maryland area. My older sister has three kids. Currently she is living with my parents and not really working. She also has a drinking problem. She leaves the two girls with a family friend for weeks on end and only calls maybe twice to see how they are doing. My nephew has recently been reunited with his birth father and she leaves my nephew with him more than she should.
All three kids have different fathers with my nephews father the only one in the picture.
I believe I could get my sister to sign her rights away to me but my biggest worry is my nephews father. How would I go about getting custody of the three kids?
