My son list custody CYS says if he don't sign over his parental rights then the state will come in if that is done CYS would automaticly take that new baby if he were to have one is this true? What are his options?

I have a relative, who married his wife, who had been very abusive and asked him many times to move out her house, just for her mental insanity. had put his clothing out on the street and asking all the time to move out. He had been very supportive and patient to his battle to this lady. Finally, she had requested for him to move out and he did. He had to go to immigration to get his green card, but she said, he will have to go by himself. Does he need an attorney? I just looking out for him. Please, let me know. Actually, he might no be able to pay an attorney, what have he shall do? Nancy
