Praise be to Allah.
If the marriage fulfilled the necessary conditions, namely the proposal and acceptance, the consent of the wife, and the presence of the wife’s guardian and two witnesses, then it is a valid marriage, even if it was done verbally. Documentation of the marriage contract is only required in order to preserve people’s rights; it is not a condition of the marriage being valid.
If we assume that one of the conditions – such as the presence of the woman’s guardian or his deputy – was not fulfilled, then it was an invalid marriage, yet despite that the wife cannot exit the marriage except through divorce.
Ibn Qudaamah (may Allah have mercy on him) said: If a woman gets married in an invalid marriage, it is not permissible for anyone else to marry her until (the first husband) divorces her or her marriage is annulled.

It makes no difference if the wife did not lose her virginity, because as soon as the marriage contract is done, she becomes a wife, and if she has moved to her husband’s house, it is haraam for her to leave the house except with his permission, even if she is going to visit her family.
Among the evidence that the husband’s permission is necessary even to visit her family is the report narrated in as-Saheehayn from ‘Aa’ishah (may Allah be pleased with her), according to which she said to the Prophet (blessings and peace of Allah be upon him): Do you give me permission to go to my parents? Narrated by al-Bukhaari (4141) and Muslim (2770).
If the woman goes out without her husband’s permission, then she is disobeying her Lord and her husband, so how about if she goes further in disobedience and refuses to go back to him?
it is not permissible for a woman to seek divorce except for a valid reason that makes it permissible to do so. If she does not have any valid reason, then she is exposing herself to a stern warning from Allah.
It was narrated by Abu Dawood (2226), at-Tirmidhi (1187) and Ibn Maajah (2055) that Thawbaan (may Allah be pleased with him) said: The Messenger of Allah (blessings and peace of Allah be upon him) said: “Any woman who asks her husband for a divorce when it is not absolutely necessary, the fragrance of Paradise will be forbidden to her.” Classed as saheeh by al-Albaani in Saheeh Abi Dawood.
What is meant by it being absolutely necessary is that there should be some hardship and a compelling reason for divorce.
From what you have mentioned, there does not seem to be any reason that makes it permissible to ask for divorce.
The woman and her family should fear Allah, may He be exalted, and adhere to the limits that He has set. They should beware of His anger and wrath.
If this wife marries another man, then her action constitutes zina (adultery), which is haraam and is a grievous crime.
It is not permissible for her to form a relationship with any man who is not her mahram, even if she is not married, so how about if she is already married? This is even worse and more reprehensible.
What we advise is to bring in a mediator from among her family, neighbours or friends, or the imam of the mosque, who can warn them about the consequences of this evil action, and remind them of the rights of the husband, and dispel any doubts they may have, because this is a valid marriage which the woman cannot exit except by means of divorce.
Allah instructs us to look for two arbitrators in the event of wilful defiance (on the part of the wife), as He says (interpretation of the meaning):
“If you fear a breach between them twain (the man and his wife), appoint (two) arbitrators, one from his family and the other from hers; if they both wish for peace, Allah will cause their reconciliation. Indeed Allah is Ever All-Knower, Well-Acquainted with all things”
Perhaps you can find someone among your family and her family who can do that.
Moreover, there is no sin on you if you do not give her her rights of maintenance and the like, because the one who is wilfully defiant does not deserve maintenance, and because she is the one who has forfeited her rights by her own actions, and has been disobedient and committed sin.
If your wife and her family insist on their attitude, then we advise you to leave her, because there is nothing good for you in such a woman.
We ask Allah to set straight our affairs and the affairs of all the Muslims.
And Allah knows best.
