My daughter used to stay with me every Friday evening through to Monday morning. I kept on hearing of more and more erratic behaviour of the mother that convinced me she has mental health issues and it was having a direct impact on the well-being of my daughter. After months of asking for an explanation and receiving no response, one weekend I did not return my daughter on the Monday as I was worried for her welfare and requested that the mother attend a Family Dispute Resolution with me ASAP. The mother's response to this was to run away to an unknown location and change her phone number, and so my daughter now lives with me full time and has done so for 10 months now. After a nine-month absence the mother sent me a text message from a new number saying she was back and healthy. When I asked her to explain where she has been and to attend Family Dispute Resolution she did not reply for weeks. This has happened a further two times over six weeks. As soon as I mention Family Dispute Resolution, she stops replying. I still have no answers as to where she is currently living, where she has been, if she has sought help, anything at all. I am scheduled in for Family Dispute Resolution myself and have sent all the details to the mother but she does not reply with anything. I am not sure where I can go from here. If she does not attend Family Dispute Resolution I will get a certificate and presumably can go to court. What happens if I go to family court and she does/does not attend? Can I even go to family court without knowing her address? I actually strongly think the mother should be a part of her daughter's life but I want everything done correctly and to ensure the safety of my daughter. Regards.
