An adult child becomes disabled before the age of 22 may be entitled to draw SSDI benefits based upon the Social Security eligibility of his or her mother or father. The parent must be deceased or drawing SSDI disability or retirement benefits. It is not necessary for the adult child to have an earnings record with Social Security as the adult child can utilize the parent’s earning record. However, the disabled adult child cannot be engaged in substantial gainful employment. Children under the age of 18 may be entitled to receive SSI benefits if they meet the criteria for being disabled and their family income and assets meet the eligibility requirements.
