Well, you can file such a petition. Check the self-help center at http://www.clarkcountycourts.us/shc/Supporting%20Documents/self_help_supportingdocs.html to see if there are any forms for that purpose.
One question you should consider is whether it is really necessary -- when you hit 18, yoiu are emancipated as a matter of law.
I would not suggest you take the advice of any family law lawyer on something like financial aid -- call or make an appointement with the financial aid office at UNLV or CSN and ask them, but I see no reason why you should be any less eligible for assistance.
