I appreciate all of the suggestions! I'm weighing each and every one.
The state is Indiana. Indiana no longer requires notarized signatures on titles, but I believe that older titles back from when they did require it, still have to be notarized at the time of sale.
I'm trying to get ahold of the guy who owns it so that I can take another look at the title, and make sure I have my facts straight. I'm almost certain his name is not on the title at all (as purchaser), so I think I could pay for the car, take it and the title/death certificate with me, and then pursue the best solution without him. I don't recall if the seller dated it or not.
Once again, thanks for any and all ideas! John
