Can a used car dealer repossess if they have an unsigned title to that and did not leave the property?

Generally, a car dealership cannot repossess a vehicle without a valid title. Typically, when you purchase a used car, the dealer will provide you with a title that needs to be signed by both the buyer and the seller. The dealer will usually hold onto the title until any remaining balance is paid off. If the title has not been signed, it may not be legally considered a valid title, which could affect the dealership's ability to repossess the vehicle.

As for the fact that the vehicle did not leave the property, it doesn't necessarily prevent the dealership from attempting to repossess it. If you have an agreement or contract with the dealership that specifies the terms of payment and repossession, they may still have the legal right to repossess the vehicle if you fail to meet the agreed-upon terms, regardless of whether it has been removed from their property.

It's essential to carefully review any contracts or agreements you sign when purchasing a vehicle to fully understand your rights and obligations. If you have concerns or questions about the repossession process or the title, you should consult with a legal professional who can provide specific advice based on your situation and the laws in your jurisdiction.
