If you are travelling abroad with your child it's recommended that you have a Consent form for travelling abroad with a minor which is signed by the parent/guardian not travelling with the child.
You can either download and print a copy of this form here: Consent form for travelling abroad with a minor, or you can pick a paper copy up from the NSE (copies are on the Hive noticeboard above the radiator).
