I am 18 years old and my sister is 13 years old. We were adopted by our cousins in 2000 and now I am moved out and I have my own apartment. I am engaged and we would like to get custody of my sister. She is being hit with a cutting boared for no reason. She is being emotionally abused and I was just wondering what I would have to do to gain custody and how I need to prepare.:confused:
