Hi, you know as I read this thread and all it occurred to me to ask you if she is on a medical disability which gives her state health insurance, or medicaid, or if you are referring to SSA. If it's medical and they have her file confused with someone elses, I would suggest that you call and speak with an agency director. I had clients who kept having this happen and their benefits getting messed up and then the files were locked for supervisors only. I sent 5 reviews once and then they finally get me to a super who told me about the locked file thing. If this is SSA, our friend here is correct. They can't stop giving you the benefits unless they inform you in writing and the entire file system theoretically can't be "lost".

If you have to do a review of paperwork once a year for your daughter for the medical stuff I think that is pretty normal. Good luck.
