The hearing is the best chance for a claimant to explain his/her reasons for seeking disability benefits. The claimant will almost always testify with the help of his or her representation. An Administrative Law Judge presides, and there are sometimes expert witnesses like vocational or medical experts. The hearing can take fifteen minutes to over an hour. These hearings are rarely combative or intense, but it is not uncommon for people to disagree. A successful hearing is when the claimant is able to present his or her best evidence and persuasively present his or her best case.
