One was given to foster parents while at elementary school, and continued using his real birth last name through the middle of grade 12, when he was transferred to another foster home in another city. Due to negligence of the new foster parents, he was registered with his real first name, but with the foster parents' last name for the rest of grade 12, after which his high school diploma was issued with the foster parent's last name. Upon reaching 18, he left the foster parents. Now after almost 25 years, he wants to go to college, but the last name on his high school diploma doesn't match his real/current last name. What can he do to get the last name on the high school diploma be corrected?
