The REG 227 or the Application for Duplicate or Paperless Title is the form you will need to fill out if you need a duplicate title. The DMVCalifornia Dmv may need you to fill out a duplicate title if your title is lost, stolen, mutilated, illegible, or if you never received one.
You will also need to fill out the Application for Duplicate or Paperless Title if you want to transfer a title. The form doubles as a way to change the ownership of your vehicle.
