And if I changed my name, can I still get a refund?
yes, you can. First, you have to surrender the vehicle plates at a DMV office and then request a transfer receipt, not a refund receipt. Secondly, you have to send some items to the address on the Request for Refund MV-215 form.
I have my unused registration sticker and stop and I got a refund for the second year of registration, can I get a refund for the first year?
Yes, you may be eligible to apply for the first year of the registration fee refund. You have a maximum 60 days after the date you got issued the registration to apply for the first year of the registration fee refund.
