Moving before the money moves
Call your bank's fraud line immediately and ask it to request a recall from the receiving bank; funds that have not yet been withdrawn or forwarded can sometimes be frozen. Report it to the FBI's Internet Crime Complaint Center as well, since that office works with banks on some recent domestic transfers to try to hold funds. Tell the party you actually meant to pay, using contact details you already trust rather than those in the suspicious email. Preserve the emails with full header information, the wire confirmation, and phone records, and stop using the compromised email account for sensitive business until it has been secured.
Who may bear the loss
Wire transfers are generally governed by Article 4A of the Uniform Commercial Code and by your agreement with the bank, rather than by the consumer rules that cover most card and app payments. Under that framework, it matters whether someone else issued the payment order from your account, in which case the agreed security procedure can shift responsibility, or whether you sent it yourself after being deceived, which usually leaves narrower claims against the banks involved. In real estate closings and other transactions, the parties may also dispute who should have caught the fraud and whose systems were compromised. Crime insurance policies, including social engineering coverage, may respond, but terms vary and notice requirements can be short.
Legal routes to recovery
When funds have been traced to an account in the United States, a court order freezing them, followed by a claim against the account holder, can sometimes recover part of the loss. Claims against a bank succeed only in limited circumstances, and claims against another party to the transaction depend on the facts and the contracts. Our first conversation covers where the money went, how much time has passed, whether insurance may apply, and whether the cost of litigation is justified by what can realistically be recovered. Unsolicited offers to get the money back for a fee, however official they look, deserve deep suspicion.
