<p>I know that you can go back to the family courts in NYC because one of my friends did just when her child got accepted to college. She requested and got an upward modification for support (state of NY holds you responsible until child is 21) that included money for tuition. She did not even use an attorney. Everyone has to bring in documentation of their finances, check stubs, w-2, copy of taxes,. She also brought in the financial aid letter from the college and it was prorated accordingly.</p>
