How can you register a car without the title mydaugther is in colo and ME in nc and she wants you to sell the car but you don't have the title?

You should be able to get a replacement title from the DMV in the state the car is registered in. Of note, it has to be the person who the title's name is in that requests a replacement. They will ask you to sign a few papers and charge I believe $10 or so.
