I'm just after some advice on whether my kids dad will need to sign a letter of prermission to travel? Their dad and I are no longer together and they have his surname. We are travelling to Spain next month and I'd like to know if anyone in a similar situation has ever needed and been asked to show a consent form? I've spoken to a couple of people who have been in the same situation, who have travelled international recently and they haven't been asked. Is it worth just getting one just incase? Would I also need to have it notarised?
