Skittles may have blazed a more secure path. As suggested read your certificate and your disclosure and see what it says about early withdrawals. You might be able to stretch the truth of that as well.
Note the possibility that if you've told Granny it can't be done for whatever reason, the family member may pose the question to one of your employees at another office without saying he's spoken to you.
There's a possibility that, pressed hard enough, I would simply tell the elderly person the truth and say I had contacted the state. There would be no mention of the SAR, but I'm thinking that might put a knot in the third party's noodle.
