This work intends to study the obligations and liabilities of advising bank in UCP 600. An advising bank has two big obligations as follows : by advising the credit or amendment, the advising bank signifies that it has satisfied itself as to the apparent authenticity of the credit or amendment and that the advice accurately reflects the terms and conditions of the credit or amendment received. An advising bank may utilize the services of another bank("second advising bank") to advise the credit and any amendment to the beneficiary. If a bank is requested to advise a credit or amendment but elects not to do so, it must so inform, without delay, the bank from which the credit, amendment or advice has been received. An advising bank has some problems in connection with the delay of advice and the advice of forged letter of credit.
