It's been a long time since I first went on SSD but I think your "Certificate of Disability" (geez, they make it sound like it's trimmed in gold!
) is the letter SSD
sent you when you originally "won" disability, it stated how much you'd get and when. Also called "Certification of Disability Determination" or "Certificate of Award" or "Notice of Award". It's not the same as the Fully Favorable letter from the ALJ ~ admin. law judge.
The FF letter is from the courts, the certificate is from SSD.
Mine actually said "certificate of disability" on top. I was told that it'd be important and to make 10-20 copies, which I did, and thank goodness 'cause everybody under the sun wanted one. That was back in '91, now I just use my 1099 tax form.
Most states (maybe not yours?) will accept the 1099, the yearly SSD benefits statement, as proof of disability. You can get a new one online, once they get back on their feet. Is it ironic that the disability website is disabled? http://www.socialsecurity.gov/d&s2.htm
In Florida, "totally and permanently disabled", applies only to the blind and those who use a wheelchair on a daily basis.
