i have had dealingfs with social services, i lost all my kids and a new born, they took her from the hospital just a few hours old, and adopted a few months later, forced adoption, the police were outside the labour room, said if we take our daughter we would be arrested, i had had there involvement in the past, from what i read up, if you have had any past involvement they will get involved, best thing to do is work with them, this is what i refused to do, which led to this, if your brother has no track record with them, i do not see why they would get involved, and should try not to worry
