If a title has been lost, the owner can apply for a duplicate title. All owners on the title must come in with current ID's. There is a $20 fee for the duplicate title and a $5 cash notary fee for signatures ($5 for the first signature, $1 for each signature after). If there was ever a lien indicated on the title, the owner must obtain a lien release from the lienholder in order to obtain a duplicate title.
If the owner is needing a duplicate title but is selling the vehicle, they can request a duplicate with a transfer. All the above applies, but the back of the form will be signed over just like a normal title.
