My brother-in-law is severely physically disabled from a progressive genetic disease. He has never been able to live without a full-time caregiver. At this point in his life, he cannot work at all. He went to college and law school and worked from 11 months around the age of 30. His father is currently retired and receiving SS. Can he draw on my father-in-law's Social Security as an adult disabled child?
Thanks for your time.
