It is possible to get a conservatorship of your son if his medical condition require this kind of supervision but the process is complex and costly. You should talk to a local Probate Attorney that handles conservatorships and discuss the matter with them.
For the Rep Payee, I would start with contacting Social Security and notifying them of your concerns in the local field office and asking what your options are at this point. They need to determine what is best for your son.
I agree with Mr. Gowen. If you have proof that she is misusing the funds as the rep payee, you should contact your local field office. Rep payees, as I am sure you know, are required to keep track and account for what the money is spent on in case SSA inquires.
They are located at 63 Aliant Parkway, Alexander City, AL 35010 (1-877-405-0483).
If you have no proof of wrongdoing, you can still voice your concerns but I do not know if that will be enough.
Unfortunately, because he is an adult, he can ask that the rep payee be changed BUT the field office is in control of appointing the rep payee.
Is your adult son mentally disabled? If so, you may be able to contact the local mental health counsel to ask for further advice and assistance with getting him access to care/services. If they are involved, there is less chance this woman will have as much influence in his decisions. I agree with my other colleagues- contact the local office and advise them of your concerns.
