I have recently split from my partener, who was physically and mentally abusive towards me also has mental issues hes not mentally stable cant even remember being violent and is getting help for this (he sounds like a dream dont he) so I have left and moved to London he has never been charged for violence as I have only reported one incident. I have not really spoke to him or his family but he has told me he wants to take the kids over the weekend and drop them off on monday. This in my eyes would normally be fine and would not have a problem with this, but I am worried (because of his state of mind) that 1. He might not bring them back or 2. He might do something to the children (that sounds horrible but I never thought he would hit me and did so cant really blame me for thinking that).
So what I am asking is what if he takes them and just doesnt bring them back can he do that? (We have not been to court over this so have nothing legally binding to say they should live with me)
How would I go about taking him to court so I am the parent they live with legally (I have to do this as there is no talking to him like a human about it all) and how expensive is it?
He has no job nowhere to live has a criminal record and history of violence so know he wont stand a chance to get custody of them im just worried that if I didnt legally have custody he would just be able to take them away from me!!!
