Parent’s Last Name
This is question 61 and 65 on the paper Free Application for Federal Student Aid (FAFSA®) form.
Enter your parent’s last name exactly as it appears on his or her Social Security card. If your parent doesn’t have a last name, enter his or her proper first name, not a nickname.
You can only use letters (A–Z), numbers (0–9), periods (.), apostrophes ('), dashes (-), or blanks (spaces). No other characters are allowed.
