Hi to evryone,

Its regarding article 9 pertaining to advising of credits.My questions are

1)How to check the apparent authenticity of a letter of credit .

2)What does it mean as in article 9b "that the advise accurately reflects the terms and conditions of credit."?

3)Finally suppose advising bank recieves an LC for advising but forgets to advise it....is it liable....??till what time can it advise the LC?

I am new to this field so can anyone please clear my doubts?
