Well, if the mother told the social services (council in UK) that she does not know where the father is in order to collect cayr, and the taxpayers' money were used to raise those kids, the deadbeat father can't just suddenly show up and claim them.
I remember this case in Atlanta, GA where a Somali father beat his son after he misbehaved in school. The children services found out and took the kid. The Somali father challenged them in court, and claimed that this is his son, he works, his family does not collect welfare, and he has every right to discipline his child. He went further and told the judge that he does not know who these people (the child services) are when they have no part in his child's upbringing. The conservative white judge agreed with him and told him "not only can you whip your child at home, you can also whip him in my court."
Not raising your children on welfare makes all of the difference!
This is why Muslims should desist from voting for illiberal faggots and transgenders. If it was one of those illiberal judges-cum-faggots, the somali kid would have been adopted by a transgender idiot would loved visiting womens toilets.
