Thank you, Asivad!!!! We didn't think it would be necessary as we are legally married and would write explanatory letter describing our previous savings on my personal account. But we have no experience in this sort of questions and because of very little amount on my husbands account your advise seems to be rational. On the other hand we are married, my money are my husbands money, right? Or am i thinking too naive?
there is another question, my husbands account was open in April so we can't provide 6 month bank statement. Previous bank account is in different bank, all closed, zero funds. Should we write it on explanation letter?
