Get him to go with you to the DMV/DPS to apply for a title in your name. Have him sign a bill of sale and have it notorized, he'll have to be with you to do that, otherwise you'll have to apply for a lost title and provide title insurance for the car until the title is researched and secured. That took about a year on my son's old Saturn, a simple process but a pain none the less. Title insurance was like $80.
