How do I convince my lying parents that FAFSA will check assets and stocks?

If the issue is parent assets, it is the parent (not the student) who is responsible for reporting the amount. When the parent signs the required verification paperwork, he/she is certifying that the information is correct.

My advice to the OP is to tell your parents that they are required by law to be honest. Tell them that any aid you are offered could be jeopardized if they lie. Then insist that THEY indicate the assets on the verification form, and do not sign the form for them; they must sign their own name.

Be sure to report the CD that is in your name in the student section of your verification form.

If your parents choose to lie, it will be on them. If you end up not getting aid, it will be their fault, not yours. I realize this won’t make you feel better, but the responsibility here rests on them.
