Wanting to know what i can do to get custody
me and my wife has been divorced since September 2007 we got joint custody of our two girls one is 9 and the other is 3. On February 29 2008 she dropped them off at my sisters for me to pick them up after work for my weekend visit with the kids. We didn't hear from her anymore for about 3 or 4 weeks. And she has not got them since. I work out of town and I live with my sister for now with the kids, my sister takes care of them while I work. She keeps my oldest daughter and puts her off to school and my youngest stays during the week with my x wife's grandparents because of my sister working during the week. The mother has seen the children but not very often, she got into drugs really bad, and when the few times she kept the kids, we were hearing later on that she didn't feed them. And she would only have them for 3 or 4 days. But her grandparents, keep defending her and has let her take the kids when they had them on a weekend or something, knowing how she is, but also because I work out of town they want to tell my sister how to run things with my kids and if not then she is going to dhs. And I don't think that is right, the kids are most happy with my sister and I feel they will try to take the kids from me. I want to know what my rights are and how much rights the grandparents have. Also this past weekend my youngest was with them on Friday and their mother came by the grandparents house to pick up some clothes and my sister called over there and the grandfather answered and said that the kids mother was there wanting to take the youngest and my sister told him not to let her take the child and the grandfather said in a real ugly way that there was nothing me or my sister could do cause she had coustdy of the kids, so once again they sided with her. I need some advice please
