Can they legally move another car in order to get the one being repossessed?

The answer to this question depends on the specific circumstances of the situation and the laws of the jurisdiction in which it occurs. Generally speaking, a lender or repossession agent is not legally permitted to move another car in order to gain access to and repossess a vehicle. However, there may be certain exceptions or circumstances in which this might be allowed. For example, in some jurisdictions, if the repossessed vehicle is parked in a way that blocks another car or causes a safety hazard, the lender or repossession agent may be legally authorized to move the other car in order to gain access to the vehicle being repossessed. It is important to note that these laws and regulations can vary from jurisdiction to jurisdiction, so it is crucial to consult the relevant laws and regulations for the specific jurisdiction in which the situation occurs.
