Myself and ex husband went to mediation this year and because of a lot of threats and arguments from my ex regarding our boys passport it was written in the mediation agreement that he can use there passports but after use they stay in mine and the boys home as they live with me. He took them across to France last week and didn’t return them at the end of the week when he brought the boys back as agreed. I messaged my ex and asked why they had not been returned and he said your not ******* going to use them so why should you ******* keep then there in our safe I told them that it is in the written mediation agreement that we both signed and he just continued to refuse to give them back and turned very nasty as he had had the boys for the first week (his choice) since we split in Feb 2017 and told me if he had his way I ******* wouldn’t have the boys full time as apparantely I’m incapable of looking after them???? Don’t think so. Anyway what do i do now can I get them back or because he has PR can he keep them eventhough we both agreed they would stay where our children live?
