My brother had an affair with a married women She had a baby and when she gave birth her and her husband put the baby up for adoption (she and her husband told the adoptive parents they were the parents and they both signed) . It's been 9mos. And she just told my brother about it and said they did it because he (my brother )was the dad. Know my brother want to know if it's his baby and if so him and is wife want the baby . Can they do anything about this, and if so what?
