If the PO comes back and says he can't find the title and YOU'LL need to file for a lost title politely inform him it is the OWNERS responsibility to file for a lost title. Usually just take the plate down to the DMV along with the VIN and the OWNER gets NEW title for a few bucks. Offer to take him to the DMV to get the title taken care of and if he starts to dance around the title subject, there may be a BIG problem..
Just my .02 cents of info!!!
