My brother got this woman in dr pregnant a year ago suppose but he doesn't think it's his son.. cause she's a hoe. He came to the US and met someone who he is married to and had a kid with her. "His baby" in dr was born last year October but he hasn't had he time to go and get a DNA test but he still supports the mother and child pays her rent food everything because she doesn't work. But she is mentally unstable she send pictures to him of her cutting herself threatens him and his partner. If I s his son what procedure does he have to do to take him away from her and gain full custody???
