Not legally. But if he had the keys then yes.
It depends on what the title says. The title can say "The owner of the vehicle is Name 1 or Name 2." If the title says this then the cosigner has limited rights to get the car. Whoever has the vehicle can sell the car without the cosigners signature. Now if the cosigner has the car, the cosigner can sell the car without the main owners signature. If the title states Name 1 and Name 2, then you have same rights as the main owner of the car. This means if Name 1 trys to sell it, they can't sell it without your signature.
On the Title it will say "and" or "or" if it says "and" then no you can't but if it says "or" then one can sell it with out the others signature
A cosigner can attempt to sell the car at anytime. However, in order for them to sell it, they have to have the other signer's signature.
Not normally, unless you are dead and your auto passed to the spouse according to your will and/or laws of your state.
no
No-they probably forged your signature
Yes. I presume you mean drivers' license and that your friend is 18 or older. Many people who do not drive own cars.
no you may not sell a car without a title if you want to sell a car you need a title
yes you can sell a car with no air bags because my friend was sold one. But the car must be secure.
Depending on the state you're in and the year of the car then yes you can sell one without a title.
Absolute full coverage, the best coverage that there is out there plus you have to add them to your insurance, plus the fact that you will be gone a year or longer leaves too many variables and loose ends untied. Will your friend steal your car? Will your friend move. Will your friend sell your car since he will have to be added to your insurance and therfore has every right in certain states to sell that car. Will your friend total your car? Will your friend wreck your car? Kill someone in your car? Sell drugs from your car? Will your friend ETC.?
NO, that's commonly known as forgery.
