Each state seems to be different. Here in NH when you finance a vehicle - the finance institute holds the title. When the vehicle is paid off, they send you the clear title. You won’t see the title if it’s financed.
How many names were on the title?
You are supposed to turn the title in and get a new one after each change of owner.
Me thinks the OP has left the building.
Yep, on his way to Oregon to have a sit down with his nephew. If he can find him.
If you go to Oregon. Once in Oregon take title and bill of sale to DMV. The title with lien will have an upper block for owner/lessee with your name and address. There will be a lower block for security interest holder/lessor with your Nephew’s name and address. Below that is a signature/date block for your Nephew to sign and date. That and of course the $70 fee should be all you need to get a clear Oregon title. As far as I know you won’t need a bill of sale but I would have it just in case. Of course it would be much easier if your Nephew would just send you the document. Best of luck.
