Can Unmarried People Share Auto Insurance? 
Yes as long as they have joint ownership of the vehicle insured . Insuring an automobile , or any item , requires an individual to have an insurable interest in that item . Insurable interest for most property items requires having an ownership interest in the item . Cars should be titled in both members name . In fact , in some states even a married couple could run into trouble insuring an item if only one spouse has legal ownership .
