I think you may be in the clear. The below is from Boalt's financial aid website. It seems as though you need to either be 30 before Dec. 31 of your enrollment year or able to demonstarte that your parents have not been supporting you for at least five years.
Determining Financial Independence
A student is considered to be financially independent based either upon the student's age or demonstrated financial independence from his or her parents.
If the student will be at least 30-years-old by December 31 of the fall semester of the academic year for which grant eligibility is being determined, he or she will be considered to be financially independent.
Students who do not meet the age requirement for financial independence will be treated as financially independent if they demonstrate the following:
1. that they have not received more than $10,000 total from their parents in the prior five years; and
2. that they have not lived more than six cumulative calendar months with their parents in the prior five years; and
3. that they have not been claimed as a dependent by their parents on any of their prior five federal tax returns.
You may obtain the Statement of Independence by sending a request to

. Please note that along with the statement you must submit a photocopy of the first two pages of your parents' federal tax return for each of the five years you were not claimed as an exemption.
