It is not necessary to obtain new insurance policies for both vehicles when switching ownership between spouses, as long as you remain on the same policy. However, it is essential to notify your insurance company of the change in ownership to ensure accurate vehicle registration and coverage. This can usually be done by contacting your insurer and providing the updated information. They may ask for documents such as the title and registration papers showing the transfer of ownership.
By informing your insurance company about the change, they can adjust the policy to reflect the new ownership status. This ensures that both vehicles remain adequately covered under the existing policy, and there are no gaps or lapses in insurance coverage.
