If your name had changed and you are looking for a refund, bring the plates with you to the DMV office when surrendering. Yu must request a transfer receipt and not a refund receipt. You then send these to the address that you'll find on the Request for Refund MV-215 form
How is my refund actually determined?
When you registered your plates, you paid $137.50, which was for two years. This amount included $62.50, which was the registration fee for two years, that is $31.25 per year. Also included was $50.00 for the title certificate and then $25.00 for the vehicle plates. The registration fee for one year is refunded to you, as you surrendered the plates during the first year of registration
If the person who registered a vehicle dies, is a refund possible?
