There was a case a couple years ago with an Irish guy whose account was mistakingly credited by the bank with 250k. He kept it, the bank pursued it but the legal ruling was that since the bank made the error, they couldn't legally force the person to hand it back. They had to rely on his honesty. Does anyone remember this?
It would be worth checking the legal position here if the amount is substantial.
