Please excuse me being a bloke asking for advice - Ex says she has passports for the children. However, I've never seen the passposts and neither have the kids so I'm not sure the passports exist. I have asked Ex for copies of the passports but she refuses. This has been going on for years. I would like proof of whether the kids even have passports. The passport office won't help without the number on the passports. If ex continues to refuse to cooperate then we can't ever have a holiday abroad. What should I do?
