Is a father entitled to marry off his daughter without her knowledge and consent, and is such a marriage valid if she has not seen the husband? And what should she do if she wishes to separate from him but possesses no proof or information about him?

It is not the father's right to marry off his mature daughter without her knowledge and consent. If he does so, he has acted improperly. We advise you to get to know the husband; if his character and religiosity are pleasing, then accept him. If you are not pleased with him, the marriage is invalid and void according to the preponderant opinion, or it depends on your subsequent approval. It is not permissible to marry anyone else until after a divorce or the annulment of the marriage. If the father insists on maintaining the marriage without the wife's consent, she has the right to refer the matter to the judiciary.
