Nikaah & Marriage Issues

Adoption

Q: We are Muslims and a childless couple. We adopted a baby girl and we don't know about her parentage. We want to give her our name and identity and raise her as our own, without telling her that she was adopted. We don't know who are her parents. Is this allowed?

Marrying one's ex-wife's daughter

Q: Is it possible to marry an ex-wife's daughter? I know a man that married a woman 13 years older and she never told him she has a daughter almost his age. They are not together any longer and he wants to propose to the daughter. Is this permissible considering he didn't know this? He didn't have intercourse with her since finding out as he was very hurt and shocked.

Married girl getting married to someone else

Q: A girl's father made her nikkah to a guy. She wasn't in the nikkah. She made her father her representative. After nikkah she wasn't living with the guy. She was still living at her father's house. Few months later she came to know that the guy is not good so she decided to break the nikkah. But her father said there was no nikkah done. After that she got married to another guy and now she is living with him. But one of her relatives is saying that her nikkah was held at that time and now she has done nikkah over nikkah. Now theres confusion about her nikkah whether it was done or not. She is now married to another guy. Is she doing zina? Is that nikkah valid? She can't even get divorced from that guy she left because these people have become their enemies.
