My ex husband has been arrested on several occasions for child sex offences and is waiting for a court appearance where he is likely to go on the sex register but still wants contact with our children. This has been going on for years and he did get access to the children but then got arrested again. And again he couldn’t see them. he doesn’t think he’s done anything wrong so is likely to reoffend. He can’t get unsupervised access but wants to write to them. I think as they are settled without being in contact, they are better moving on without the disruption of him in and out f their lives. I don’t want them to know he’s a risk to them sexually because they are too young to cope with it. I need to keep my children safe and think getting letters will unsettle them. He’s never going to get access again. How can I protect my children?
