David;
Having legal representation in Social Security Disability hearings is not a requirement but other's experience, including that of my wife, has shown it to be highly advisable. SSD benefits are not like unemployment benefits, where all you need is proof of unemployment (not for cause) and show an effort to find work. As a former radio broadcaster (disc jockey) I collected unemployment benefits between gigs with little trouble as I was usually unemployed because of ratings or a format change not of my making and I was eager to get back on the air, as unemployment paid poorly. I hated having to collect it but did so out of necessity.
Social Security Disability awards are hard to get in many cases and your first application is almost automatically turned down. It gets very frustrating. Figure close to two years until your case is resolved. They demand volumes of medical documentation and question everything. They'll likely ask why you can't simply do something else ('retraining'). These are just some of the reasons you may want to consider retaining an attorney that specializes in securing Social Security Disability benefits. There are many of them in any city and they can be a big help. Most will take a portion of your award (benefit) that accumulated during the time from your initial application until the final decision, assuming you're approved. So, if your 'award' is $1,000. per month and it takes, say, 18 months to resolve the case, you'll receive a lump-sum award of $18,000. The attorney may take a third of that ($6,000.) Of course, the problem is: how do you live in the meantime? I'll leave that question for you to answer but you can see why many folks simply give up or don't bother applying for Social Security Disability benefits. It's a hassle and, in the end, you could lose the case.
I wish you all the best in your recovery and if you decide to pursue SSD.
