My ex and I have a childcare arrangements order in place which specifies that my ex gets X amount of holidays per year (2 weeks in the summer, 1 week at Christmas and half of the half terms) so we have to agree dates. The order also says that my ex is supposed to give me certain information about any foreign travel, e.g. flight time, where DCs are staying etc) well in advance.
So, my ex asked a few months ago if he could take DCs, 10 and 8, to see his dad who lives abroad (in Europe). I agreed but now have good reasons why I don't want DCs to go including that my ex's dad slags both me and my DH off and last time they saw him it took a week for them to settle.
Question is, can I now withdraw consent to them going abroad? I don't mind my ex having them half the holiday but don't want them to leave the country. As I said, we have a child arrangements order in place and a residence/live with order in my favour.
