How do I transfer SSI for an eligible dependent?

Why is he getting SSI? You will have to have guardianship papers for school, medical care, and to get the SSI changed to you being the payee. There will also be other things you will need them for. You would have to go to your local social security office to apply to be the payee. You would not need her consent, it is up to social security to appoint you. Medicaid will not payout in another state unless it is an emergency or a pre-approved specialist. You will have to reapply for medicaid, and it will only take a few days. There also may be a change in the amount because some states supplement the benefit and some don't. But also because he is moving in with you, your income and household members might affect his SSI. It is possible it will cut out all together. It might be in your and his best interest to consult a lawyer to guide you though this.
