1) In some jurisdictions, the co-owner may have a right to possession of the car if they are identified as a joint owner on the title.
* In this case, the co-owner may be able to take possession of the car without needing to go through the probate process.
2) In other jurisdictions, the car may be considered part of the deceased person's estate and may need to go through the probate process before the co-owner can take possession of it.
* In this case, the co-owner may need to file a claim with the probate court to establish their ownership interest in the car.
In either case, it is important to consult with a legal professional familiar with the laws of your jurisdiction to determine the specific rights of the co-owner and the proper procedures for taking possession of the car.
