Sorry - posting for traffic.
Inspired by another thread that's running at the moment, I wanted to ask a question about this as Google tells me this could possibly cause issues for us at the airport!
We are a family of 4 - DP and I unmarried. 2 Dc, one mine from previous relationship and one both of ours. All 4 of us have different surnames. Mine, DP and DC1 are totally different. DC2 is a double barrelled combination of mine and DP's.
Are we likely to have problems at the airport taking 2 children abroad who do not share a surname each other or ourselves? Is it recommended that we take their birth certificates, too, just in case of any awkward questions? 🙈
