The SF 180 seems to conflict itself on what qualifies as next-of-kin.
The instructions, lacking "grandchild", state this:
However, the fillable form has a drop-down field for next-of-kin, and that includes "grandchild".
Which one is correct?
Are grandchildren considered to be next-of-kin for the purpose of this form or not? Why is there a discrepancy?
