Minor travelling to France

[newnameswhothis]

My 4 year old daughter is going to DLP with her Aunt, Uncle and cousins for 3 nights in Feb.

As she has a different surname for them does anybody know what I would need to provide for them to travel with her other than her passport?

Whenever I have accompanied minor family members, I've had the parents provide a signed letter authorising me to take them abroad.

Flight/train numbers, dates, address she'll stay at and passport numbers and full names, DOB, address of yours and/or her dad, if there's one on the scene.

A copy of your own passport would also be good to have. On top of that, provide another piece of paper with your phone numbers and email that you can be contacted at. I have previously been called by border control to check that I was indeed collecting X or had allowed Y to travel with Z.

A consent letter. The UK gov website has the information you need. You can download a template.
And ignore the posters who will say they've taken kids all over the world and nobody has ever stopped them.
A sample of passengers with children are stopped- most often single men with minor , followed by single woman, or someone clearly not the parent.
It's nothing to do with surnames, though obviously the officer spotting that may well investigate further. It's to do with cross border abduction.
That bit where the nice lady asks the child "are you going on holiday with your dad then?" That's what they're checking.
