Many of my clients think all they have to prove is that their medical problems prevent them from doing their past relevant work. For some claimants, that is all they have to prove. For the majority of Social Security Disability Insurance Benefits and Supplemental Security Income claimants, that is only part of the battle. For most claimants, especially claimants under fifty years old, even after you prove you cannot perform your past relevant work, you have to establish that there are not significant numbers of other jobs in the national economy that you can perform. This is where most claims before an Administrative Law Judge are decided. You might not be able to perform your previous job as a construction worker but, especially if you are under fifty years old, could you perform a desk job? If the answer is yes, the Administrative Law Judge will probably deny your claim for Disability Insurance Benefits or Supplemental Security Income.
You should consider contacting an attorney that specializes in Social Security Disability claims if you are unable to perform your past relevant work due to a medical condition and are worried about what exactly you have to prove to qualify for Social Security Disability benefits.
