Tier1 extension - duplicate bank statements

[ldbright]

Two months of my RBS bank statements are duplicated ones ordered from the Bank (not the branch, i.e they are not print out). They look exactly the same as the original one apart from it got the word "duplicate'' on the corner. Want to ask if they are OK to be used without stamp and sign?

Please can someone kindly answer.

Should be okay. But if you are not sure, you could still take it into a branch to get it stamped.
