How could she have LEGALLY signed over the child, without his signature? It could be done, if they weren’t married, but marriage should confer some sort of protection for the spouse who is not making this decision. She could have gotten an abortion without his say in the matter, but once that baby was born, it was legally HIS, as well as hers.
The adoption agency Adoption Center of Choice told the new family that Mr Achane wasn't aware of his daughter's placement with them and he would most likely contest it if he had found out.
Then the new 'family' are a despicable lot.
