Social Security is a federal government program, primarily funded through payroll taxes, that provides an array of benefits to retired workers, the survivors of workers, the disabled and low-income families. Social Security attorneys typically work with one of two groups of clients. Many Social Security lawyers focus their practices on working with those whose applications for Social Security Disability Insurance (SSD or SSDI) have been denied. These attorneys assist clients at eligibility hearings and throughout the appeals process. Other Social Security law firms represent those who have been accused of Social Security fraud and those who are victims of Social Security fraud.
