travelling with DD but without DH - do I need a letter?

[newkid]

I am taking my dd on a short break to visit a friend in Europe. I am married but have different surname to DH (and to DD) - do I need a letter from him to say that he knows I am taking dd out of country? Anyone done this?

We've taken dsd to France with us and she has a different surname to the rest of us. All we had was her passport and we didn't need a letter from her mum.

Just would hate to get to airport and be told you cannot fly as your DH is not here or that how can you prove this is your child!

Our children have dh's surname. Travelled for more than 10 years now without him visiting my family and only once at the airport in Germany at Christmas did the passport guy ask if they were my children. I used to bring a copy of their birth certs but don't bother now.
only thing to watch is that the names on passports match names on tickets.

Presumably she has her own passport?
Children can travel with anyone can't they?
The only time it was a problem was when children were on a parent's passport so couldn't travel with anyone else.

Ahh am going to Germany so must hope that I get uncharacteristically inefficient German border guard. But a lot of German women keep their maiden name so maybe not a huge problem (at least the friend I am visiting uses her maiden name).

Thanks for the responses they are reassuring. I might bring birth cert just in case. One reason I'm a bit worried is that we had to send in our marriage cert to the passport office when we applied for her passport as I had a different name to my husband.

Newkid - we live in Germany and like I say, was only asked once. He seemed to be going through the motions tbh. I was half way through the sentence "They have my husband's name..." when he obviously stopped listening.

The passport application thing is common but on hols you may be better off taking a copy rather than an original cert.
