If you are unable to work because you have physical or mental conditions that make doing your former job impossible, you may be eligible for disability benefits. However, disability benefits can be notoriously difficult to obtain, and it is recommended that you seek the assistance of a competent attorney who is experienced in helping clients get approved for disability benefits. Approval of disability benefits requires that the applicant provide medical documentation that attests that he or she is unable to work because of existing medical conditions. The courts, however, frequently apply their own interpretation to individual situations. Only a little over one-third of those who apply for disability benefits are deemed eligible the first time they apply. Many people have to apply several times before the courts will approve them, which is why the services of a good lawyer can be invaluable.
