My ex keeps threatening that he will not return our children to my care.
Q: My children have lived with me for most of the time since their father left us, but as he was on furlough from the start of the coronavirus pandemic, I agreed to them spending more time with him, to ring some changes for them because of home schooling. Now he has been made redundant and has suddenly decided he wants to keep them. He keeps threatening that he will not return them to my care. Can he just do this? What can I do to stop it from happening?
