I am about to apply for Social Security Disability for my brother. At present we are applying for Temporary Disability from Welfare. One of the pre-requisites is he must also apply for for SSI. I am acting as his representative and I have completed the SSSI Disability form online but have not submitted it as yet. Can I use the doctor's form for welfare to make the application for SSI Disability? Do I have to see a lawyer before I submit the application? In the last section where it says "Do I have any additional comments to make", do I put the Doctor's Comments in this section? What do I do, I can't afford to muck up this application?
