Quite a strange question here even if I say so myself. My son was born in Thailand and so has a Thai Birth Certificate and an English translated copy, as well as a British passport. As yet no Thai passport.

On his Thai documents it does not include a middle name, unlike on his British passport. Our priority is to change this by giving him a Thai middle name on his Thai certificate before getting him a Thai passport. His British passport has an English middle name at the moment, which I guess we could change at a later date in England.

The basis of my question really is could you foresee a problem for him to have a different name on his Thai documents than on his British ones?

As long as his first and surnames are the same, then it shouldn't be a problem, especially when travelling and using two passports.

My Australian passport doesn't include my Thai middle name 'Samran', only my Anglised middle name. My Thai passport has both middle names.

Not a problem in more than 20 years.

Most Thai's don't even have middle names. The fact that I have two is a source of amusement each time I am dealing with the bureacracy.

Don't worry - you'll never need to mix documents anyway. Thai documents usually only get seen in thailand - just like a normal Thai with the one citizenship. Non-Thai docs (ie British in your case) get seen in the UK, and of course, no need to show Thai docs there.

Never the twain shall they meet!

i'm not sure but i would have thought if the names were different booking things like return flights maybe tricky ?

if you fly between thailand and uk, when you arrive in thailand show the thai passport with no visa etc needed and vice versa ? i guess you can do that anyway even if the names are slightly different on the boarding card.

how did you manage to get different names ? when i applied for uk birth certificate and passport i had to show the thai birth certificate and was told the names had to be identacle.
