A vendor submitted an invoice for payment, he was paid for that invoice. We received a call from this vendor and he states he split the payment with another trainer that helped with the training. He wants us to correct the 2009 1099 to show half of the payment to him and half to the other trainer. Because the check was made out to the one vendor I don't believe we should revise the 1099 and make two. We have no confirmation that the other trainer received the money. What if any obligation do we have to accomodate this vendor? What options does the vendor have if we do not revise the 1099 (meaning how does he report that half of the payment went to another person)? Thank You
