If alive, the student will have to request a non-custodial parent waiver from Syracuse’ financial aid office.
The waiver request is at https://cssprofile.collegeboard.org/pdf/css-profile-waiver-request-non-custodial-parent.pdf . How likely a specific college is to grant a waiver may not be the same as for some other college.
Recommend that you advise the student to make their own account. The parent can also make their own account (separate from the student) as well. In addition to the privacy issues that the forum rules are concerned about, you being an intermediary increases the chance of inaccurate information getting passed in either direction (“game of telephone”).
