I have been deposting a monthly overseas cheque (in US dollars) into my NZ bank account for the last 5 years or so. I do this via the banks envelope deposit box, and it ends up in my account a few days later. This month I made a deposit, but noticed it didn't go into my account. The next week I contact them to ask them why it didn't go in. They told me that I didn't sign the back of the cheque to endorse it, so they didn't deposit it. They said and I would need to make a trip back to the branch to sign the back. However I have never signed the back before on previous ones and they have gone though fine. Nor did the deposit bag I filled in with my name and account details, say that I must do this. The back of the cheque also doesn't say that I must sign the back of the cheque, although there is a space that could be used to sign it. Also the banks terms and conditions don't say that I must sign cheques that I deposit. I also beleive that endorsing a check isn't required, if the person depositing it has an account with the bank that it is being deposited to.
Is this normal for a cheque deposit?
