To be err on the side of caution why not file a move away petition? I am concerned about the history of the case and whether CPS has an interest in this, too. Also, Juvenile Court may have issued an exit order, usually with a six mos. time frame, often advising that after 6 mos the parties modify the custody orders in Family Court. I don;t know what if any orders Juv Ct issued and what they father will "claim" if she ups and moves without notice but often it goes like this. Mom abducted and concealed our children; she knows how to get a hold of me etc etc and when you ask his family to testify for you that they refused to give out his address etc as you say here, are they going to back you up on all this? I am just give food for thought not legal advice. I don't know your case specifics. By your question (how fast can she take the kids out of state w/o telling dad...you already suggest the answer that you want someone to tell you that sure just take the kids out of state and don't tell dad. I think your daughter should sit down with a lawyer. Have the lawyer look at the court orders. Go from there. Its too serious of matter to get a one off , off the cuff answer on a website. If you want to hire me or find a lawyer for her
