Can I Add My Brother To My Auto Insurance? 
In California , all the drivers in a household should be listed on the auto policy . The policy covers all the drivers in the household unless they are excluded . If your brother lives with you all you have to do is notify your agent . If your brother does not live with you but is going to drive your car , with your permission , you are not required to do anything . Insurance follows the car and the car will remain insured as long as the driver has your permission to operate the car .
