I went to a Ford dealership and traded in a slightly older truck for a slightly newer one, and financed the rest.
The next day, my fiancée informed me that the title of the old truck is still on a loan she took out a year ago. We still owe $9000 on the loan. (How and why my title is on someone else's loan is a long story, but doesn't matter to the question.)
Now the dealership, of course, wants the title to my old truck. They are not yet willing to say what would happen if I don't produce it.
What are my options if I can't produce a title for a vehicle I just traded in? How does my having financed my truck affect this scenario?
