I have been trying to help my dad out on our situation and am having trouble finding the information that we need. The problem is that 4 years ago my parents divorced. I have 1 brother and 4 sisters. I am the oldest, 18. My mom remarried 2 years ago to a man she dated for 6 weeks! They immedieatly moved to the west coast and left all of us with my dad. *My mom is a manic-depressive* My mom #1. Never invited us kids to the wedding. #2. Moved without telling my dad. My sixteen year old and twelve year old sisters were living with my mom before she moved. They were on weekend visitation with my dad. My mom just never returned to pick them up! And #3. Only contacted any of us about 3 months ago via mail. Now, after 1 and 3/4 years, my mom calls up my dad and says she is coming to take all the kids with her on June 1st. My dad said "hell no." She said, "Fine, you'll hear from my lawyer." My dad has not heard from her lawyer. My fear is that my mom will come and try to take my brother and sisters away. We live in minnesota, they live in California. I am 18, so I am not worried for me. I am not f***ing going anywhere. But what about my sibs. My dad never tried to get any support from my mom and he never set up any custody arrangement. He just 'went with the flow.' My dad takes great care of us. He even is paying for my college career. My sibs love living with my dad. They all say they don't want to go. What can my dad do?
