On my court order, it says that as the kids reside mainly with me and I am the main carer, I am entitled to take my kids out of the country for up to a month without his permission. He needs to ask my permission.
In terms of contact arrangements, we are meant to be flexible with one another.
I am afraid I don’t know if this is the general rule if no court order is in place.
If you call the Family Lives helpline, they might be able to direct you to the right people to ask.
Good luck X
