Field 57a in a Letter of Credit (LC) context is not a clause but a field within the MT 700 SWIFT message type. It specifically identifies the bank through which the documentary credit is to be advised or confirmed to the beneficiary, if that bank is different from the receiver of the MT 700 message.
In summary, 57a defines the "Advise Through" Bank.
| Field | Description |
|---|---|
| 57a | Advise Through Bank: Identifies the bank, if different from the Receiver, used to advise/confirm the LC to the beneficiary. |
