Now we are living back in the uk, for nearly five years, would like to transfer my daughters account, 11 years old,  to her English building society. Account. 

Can anyone explain how this might be done. 

Her thai bank is kasikorn.  Apparently she is too young to have internet transfer. 

Thanks in advance,. 

Basically you are saying you want to close the account and transfer the funds to a foreign account.  You must physically visit the branch to do that.

 

Ok, thanks, I was hoping to be able to avoid returning,. 

Can power of attorney do it, ??

Doubtful. Recommend you contact the bank to see what options may be available.
