I believe you can sell it if you are the beneficiary, or if you inherited the vehicle.
Unless they're an agent licensed by the title holder to sell the vehicle, they've committed a crime, and could face charges.
You cannot sell a car you have a loan on if the lender has a lien on the vehicle. You will need permission from the lien holder to sell the car. If the lender has no lien on the vehicle then you can sell it if you wish. The title will list any lien holder.
No. A vehicle cannot be sold without a clear title and the only way to obtain such a document is through the lien holder.
You have to find out who the executor of the estate is. They should be able to sell you the vehicle and sign the title over to you.
If you were related to the deceased, you will need to take a certified copy of the death certificate to the motor vehicle office in your region. If you are not related, then the "estate" will most likely have to auction it off or sell it.
You need to inquire at your state DMV to determine how to transfer the title properly.
If lender's name is on the title as owner and/or lien holder they have the legal right to recover the vehicle and sell it if they choose to do so.
Legally No. How can you sell something you do not own. As long as there is a lien, you do not own the vehicle outright. Go see the lender and get a lien release, if you no longer have a loan on the vehicle. Remember the lender is part owner of the vehicle until you make that last payment. If you clear the lien buy using the proceeds from the sale, you can guarantee a title within 30 days (required by law) to the new buyer. The lien holder will then release the title.
Legally, NO! You can sell the vehicle to anyone if the vehicle is over 10 years old and you sell it for parts only, but if the buyer wants to drive the vehicle, they will need a title.
You must have a title to sell a vehicle if the new owner plans to title the vehicle. If you are selling the car for "parts only", and not planning to put the car back on the road, then you can sell it with a bill of sale only. If they want to title the vehicle, you need to go to your local DMV and apply for a lost/stolen title. Once you get the duplicate title, then you can sell the vehicle.
You can sell a vehicle to a salvage yard for parts with a bill of sale if they don't intend to resell the vehicle, but if you sell it to an individual, and they want to register the vehicle, they will need a title.
If you and your deceased spouse were listed as "OR" on the title, it only takes on signature to release the title to the new owner. However, if the names were listed with "AND", then both signatures would be required. Since this is no longer physically possible, you need to take the title, along with the certificate of death, to the motor vehicle office and have your deceased spouses name removed from said title before you even attempt to sell or trade in this auto.
