Letter of Credit Forum

Our Bank decides to add confirmation to a deferred payment L/C. As the confirmation bank, we are nominated as the presenting bank.  We understand that once our confirmation is added our undertaking would be extended to the final payment of the Issuing Bank according to the terms of the L/C against presentation of compliant documents.   What about, if discrepant documents are presented, but Issuing Bank would like to take up the documents discregard discrepancy?   Can our bank be at liberty to elect to reject the documents at our side and terminate our confirmation due to discrepancy?  Of course, we will be acting to pay the Beneficiary upon receipt of fund from the Issuing Bank at the maturity of payment.

Your professional opionion are highly apprciated.  Thank you.
