The simple fact of the matter is this: the vast majority of SSDI and SSI claimants will have no idea how to properly and thoroughly prepare a disability case for a hearing, whereas a disability lawyer has a high level of familiarity and expertise with Social Security rules and regulations. The attorney will know what a judge will be looking for with a particular medical condition, and will know what questions to ask your doctor.
Because disability attorneys get paid on contingency (only if you win), they do a great many things to ensure that an SSDI or SSI claim will have the best chance of winning. This includes tracking down important medical records and test results, obtaining detailed statements from a claimant’s treating physicians, and, at the time of the hearing, applying a thorough understanding of SSA regulations and prior rulings to the disability adjudication process.
