UCLA Financial Aid Non-Custodial Parent?

<p>I just got accepted as an out of state student at UCLA for the class of 2018 and my parents are divorced. As they only require FAFSA (which accounts for the custodial parent only), I am worried that after I accept the admissions offer (if I do) that they will require tax documentation or something from my non-custodial parent and I won't get as much financial aid (my custodial parent makes much less than my non-custodial). As UCLA is giving me more than half off the total cost in grants and scholarships, it is a very appealing option and I don't want to end up paying a lot more at UCLA than I expected when other, less prestigious schools would have given me more money. Thanks!</p>
