UK spouse visa bank statement

hi i have a queation about UK spouse visa. im japanese wife who got married to British guy.
in order to apply for my spouse visa UK, I have to submit my husband's 6months bank statements and do they have to be like an official or original ones or is copy one ok?
my husband went to his branch and got his bank statements which has his name, address, and his bank account No on it.
but is it ok or will we need to ask for the official ones?

You'd need to ask this question on a forum related to the UK, not about Japan.


Just for your information, when we submit any documents to the Japanese immigration authorities, I take a photocopy TOGETHER with the original, show them together (show that it is a true copy), and then submit just the photocopy. This is when we go to immigration in person, so if you are sending it, it will have to be a copy, because the immigration office does not return the documents submitted.
