Quoting
Mr. Knowitall
In North Carolina, once paternity is established an unmarried father has the same rights as a married father. If she tells the police what she told us: that the father is in fact the father, that she doesn't know whether paternity was established, and that she's acquiesced to his custody for three weeks, they should be telling her to go to court. The police shouldn't be treated as a "Hail Mary" solution for parents who don't take the necessary steps to establish and protect their rights. If paternity has been established, you would be advising her to do to the father exactly what she's complaining that he's doing to her.
DSS is open. If mom wants to know if dad established his paternity, it is easy enough for her to find out. Everything else flows from there.
