Can I add my Fiance to my auto insurance in pennsylvania if he is not listed on the finance contract? 
Your finance agreement and your insurance are two separate issues . The insurance is merely providing your lender a security interest in any claim payment made for damage to the collateral - your financed car . As for the insurance , you might be asking whether you can add your fiance to the insurance policy for coverage . Most companies will add regular operators of your vehicle to the drivers list and provide insurance coverage when they/he operates your car . You 'll have to check with your insurance company to see whether they will add your fiance as an additional first named insured on your policy but I suggest that until you have married , it is best that you keep the policy in your name , add him as a named driver , and keep your interests simple for now . There are complex issues about insurable interest that may be best left off this answer . And as always , check with your local agent or your insurance company for the best answer on how they think you should proceed .
