Now you're throwing the birth certificate and the ss card into the mix too?
I think you're carrying your CIP out too far because it's only muddying the waters. Why do you need the birth certificate & ss card? You said the borrower uses middle and last on everything. You've got a driver's license, pay stubs and cbr to support that so go with it.
btw, if this is a refi you've got a whole different kettle of crawfish to deal with. You need to go with the name that's on the deed, not anything you've gotten for CIP.
