What is an "Attorney Supervisor"? And who does this person work for?
The legislative intent is to allow for the qualified student loans of the designated beneficiary or the designated beneficiary's sibling to be repaid, up to a limit of $10,000 using 529 funds without tax or penalty. If you are the designated beneficiary, your qualified student loans are eligible for repayment from your 529 account.
How are you being prevented from taking a distribution from the 529 account and then using the money to repay your qualified student loans? The 529 plan administrator shouldn't be acting as a gatekeeper to make sure you are only using the money in certain ways that they approve of. That's not their job. If 529 money is used for a non-qualified purpose, it's up to the recipient of the funds (beneficiary or account owner) to make the proper reporting on income tax returns. If you are the account owner, it's your money and you should be able to use it for whatever you want, subject to income tax and possibly a penalty on the earnings portion of distributions used for non-qualified purposes. Tell the plan administrator/"Attorney Supervisor" to pack sand.
