My friend, who is legally, mentally disabled, had a vasectomy. He told the doctor’s office up front that he had Medicare, and could not afford it otherwise. They said he was fully covered, and told him it wouldn’t cost him a penny out of pocket. Now, fast forward a year and half later, they are sending process servers after him with civil warrants, claiming he owes almost $2k. His IQ is very low, and he has extreme anxiety and schizophrenia. He cannot mentally, represent himself. He makes just $600/monthly on his disability check. Where can he get free or very low cost legal assistance?
