Can someone else insure a car you own?

Answer 1

insurance for some one else's vehicle, yes another person can insure someone's else property, so long as you have an INsurable interest or authorization to do so and the owner is benefited, In other words, The owner also has to be a listed insured on the policy.

If you give the permission to another person. obviously they will have an insurable interest, however, only the legal owner of the property can receive compensation in the event of a covered loss

you can not insure the property of another when no insurable interest exists
