The PRICK that came up with the "529" plan should be shot. MASSIVE PITA to use when it's time. It was such a mess that we just ended up paying all the bills as our son went through school and AFTER he graduated he withdrew the cash as INCOME and paid the taxes on the money. It was a real shit show. I'm STILL pissed off at Fidelity and how they made it impossible to use the money when it was needed. They wanted copies of EVERY expense and would only cut us a check AFTER the receipts had been verified and more and more and more. I got way pissed at them and chewed the "managers" little ass out. I also pulled a LARGE amount of money out of their shitty firm.
OP,,,If I had it to do over I'd have put the same amount of money we put in the 529 into EPD ( MLP pipeline stock) into an account TITLED in my sons name and put the stock in the DRIP mode from day one. Easy, no issue, liquid and safe with NO ASSHOLE EMPLOYEE to deal with.
