You're wrong, in Europe you can make instant wire transfers in less than ten seconds now, with SEPA Instant Credit Transfer. You just need to know the SEPA account number(IBAN) of the person or the company to pay. Only few dozens of cents are usually charged for those wire transfers.
And a quick web search tells me that such payments can be reversed for a massive 13
months after the payment date.
AFAIK a request can be sent during 13 months but the recipient is free to accept it or to refuse it.
A recall can be issued up to 10 days after the submission of the initial payment if the request is initated by the debtor bank. Recall requests initiated by the customer directly can be filed up to 13 months after the transaction has been completed.
The recipient of the recall (the credited party of the original transaction that is being recalled) can either accept or reject the recall request. A decision has to be returned to the sender within 15 days from receiving the recall request.
If the recall is accepted, the recipient can decide to return the entire payment amount or keep part of it (e.g. for processing costs or to cover the costs of the return).
