When money leaves an account and does not come back, the first question is never who committed the fraud — it is which set of rules governs that particular rail. This article explains why the same stolen dollar can be fully refundable, partly refundable, or gone forever depending on whether it moved by card, by ACH, by wire, or by check. It covers the pivotal legal distinction between an unauthorized transfer and an authorized one induced by deception, which decides most consumer cases before any facts are examined. It walks through the error resolution machinery, the consumer liability tiers, and the very different world of commercial accounts where the loss usually stays put. It then covers wire recall, check warranties, and the practical recovery steps that actually work in the first forty-eight hours.
