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

Nevermind on the cal grant and scholarship financial aid. It says on the website that they won’t disburse federal or state aid until verification is complete. Also, I’m pretty sure that the $30,000 was in their account before I submitted my FAFSA. If I am finally able to resolve this with my family and I put the correct amount. Can I explain the situation to the financial aid office with the fact that the money was a loan from a family friend or will I just have to put whatever amount it was? Once again, thank you to all of you guys for helping me.
