Any ideas what paperwork is needed if I take my kid who has a Thai Passport to the UK, we've got the visas, tickets etc, but there's a chance that her Mum won't be able to come so just me and my kid.

Cheers.

I'm sure there are people on this board who have done it....but no one seems to be able to answer this a the moment.

Best ring the airline to see what documentation they require from children travelling with one parent as I know there definetly are requirements to protect children from being 'abducted' by one parent.

You need all the usuall visa stuff plus parental permission to travel Essential Travel Documentation for Single Parents

The document above has been compiled with legal advice and used successfully by many parents.

I'd also suggest that you register your child with the British Embassy and get him/her a British Passport as soon as possible, it will undoubtedly come in handy in the future and is one of those.... "I'll do it later" ... things that never get done later and then suddenly become a huge problem.

Talk to your lawyer to get a document authorizing you to take the THAI child abroad.
