I understand that UK Border Agency (or a trusted third party) may make reasonable checks to confirm the accuracy and authenticity of evidence I have
provided and documents I have submitted with this application. I further understand that UK Border Agency (or a trusted third party) may also make
reasonable checks on any sponsors to my application to verify statements contained in the application and establish that I will comply or have complied
with the terms of any visa granted.
Yes but it was my Fiance who signed that, not me? and they are my bank statements. How can the ECO call and get informaiton about my current account when I have not signed anything to say that they can make checks to confirm the accuracy and authenticity of evidence?

Also I just called my bank and they said they will not give any information out to anyone, even a government body.


NO! yellowcloud
They can only get verification on the information you supplied.
Current balance (ie July 18 2012) is not allowed to be asked or given.
If you supplied a bank statement to UKBA that showed a balance £100 on April 20th 2012 they can ask for confirmation of that.

They cannot ask about you 'current balance' . They can only request verification that the balance on the date of xxxxx was ££xxxxx
They cannot ask for nor be informed about 'unknown personal information'
OK
Terpe, ahhh thanks for that. There was me being stressed out about what if my bank balance changes between the application date and the day the ECO reviews the application and the ECO phones up my bank and get my current balance etc. How did you find that out Terpe? I really appreciate it.

Wel there was two different answers there on this thread, but good to sort it all out.
