I was lodging a cheque for €6k in to my savings account in my local credit union. It was coming from my current account. Both accounts are in the same name. I was asked at the counter for the source of the funds. I said that it was coming from my current account. This did not satisfy the person at the counter. I tried to explain that my bank had already ensured that my funds were covered by money laundering rules. Am I required to go back, and how far back to tell them where the funds came from? At the end of the day if I had said that I had sold my two prize budgies would it have made any difference?
