So, male friend, let's call him R, is divorced and has 2 DDs 5 and 7. Marriage break up was caused by serial infidelity on the part of the wife. Both with new partners now.
They have the usual every second weekend arrangement but it wasn't formally agreed in court. This is usually works ok unless she sees fit to change it to spite him - but he doesn't have a lot of money spare to go to court.
Anyhoo R wants to take his kids on holiday -he is Irish and wants them to see his homeland and ExW says he cannot take them out of the UK - no reason given except that she doesn't want him to.
He can't insist as she will just say nothing until the day before they are due to go and then pretend one of them is too ill to go - older one has asthma so it would be easy to invent an attack he would never know any different.
But he really wants to take them away- what should he do?
btw - there is no suggestion that he wouldn't bring them back or anything so that's not the issue.
