Mississippi Code Title 63. Motor Vehicles and Traffic Regulations § 63-21-259

(1) On the death of the owner of a motor vehicle that is the subject of a beneficiary designation, the following rules apply to an interest in the motor vehicle:

(2) If an owner is a joint owner with right of survivorship who is survived by one or more other joint owners, the motor vehicle that is the subject of the beneficiary designation belongs to the surviving joint owner or owners. If an owner is a joint owner with right of survivorship who is the last surviving joint owner, the beneficiary designation is effective.

(3) A designated beneficiary takes the motor vehicle subject to all encumbrances, assignments, contracts, liens and other interests to which the vehicle is subject at the owner's or last surviving owner's death, as applicable. The transfer to the designated beneficiary does not affect the ability of a lienholder to pursue an existing means of debt collection permitted under the laws of this state.

(4) The transfer to the designated beneficiary upon death is not a taxable event, regardless of the designated beneficiary's relationship to the deceased owner of the motor vehicle.
