If the ownership of a registered vehicle changes the law requires the seller and and buyer to notify the registrar of motor vehicles in writing?

Yes, when the ownership of a registered vehicle changes, both the seller and the buyer are legally required to notify the registrar of motor vehicles in writing. This ensures that the vehicle's registration records are updated to reflect the new owner, which is important for legal and liability purposes. Failure to do so may result in penalties or complications regarding vehicle registration and ownership disputes. It's advisable for both parties to keep copies of the notification for their records.
