helpppp! i don't understand what notary public in non custodial waiver request means

Hi, I am an international student. As I am filling the non custodial waiver request, i see the line "for notary use", signature and seal at the end of the form. I dont really understand. Do I need to have the seal and signature from the court that verified our parents' divorce or do I need to get the seal from us embassy??? pls helppppp
