What can you do if you bought a car from a person who is not licensed to sell cars and he repossessed it without notice?
Were you in DEFAULT of the contract the car was collateral for?
If so, not much to do about the repo except pay up. Obviously, the
"not licensed" part didnt bother you when you bought the car. Call
a local attorney for state specific advice.
In many states, notice of repossession is not required. The
licensing of the seller is neither here nor there, because that
does not affect the fact that you owe him a debt. There may be laws
regarding your rights to reclaim the car after paying the back
payments and costs of repossession.
