If Scamchaser is monitoring this thread, I am sure he could offer a general opinion. If memory serves me, he has represented both sides of these cases before. Also, Keyfactor by no means was I trying to "rattle your cage".
if you signed the assignment letter, you are obviously bound by its terms.
You are absolutely correct keyfactor. An improperly completed B/L causes countless problems. I am still amazed to hear from some carriers that "the shipper didn't give us a B/L"! If that happens, the driver should grab his pad of blank B/Ls and start copying down the pertinent information and get a signature. There is no excuse for a driver to leave a shipper without a B/L, either the shippers, or his own. A Commercial Invoice, or packing slip is not a Bill of Lading.
