Is the wife obligated to provide for the children or to share in their provision after her husband marries another woman without her knowledge, and is it permissible for her to seek divorce due to jealousy?

The maintenance of the wife and children is obligatory upon the husband according to what is customary, and the wife is not obliged to spend from her private money unless it is a donation. The money a woman earns from her work is her exclusive right, unless the husband stipulates taking a portion of it in exchange for his permission for her to work. A husband marrying another woman without his wife's knowledge does not affect the obligation of his maintenance or his justice, and he is not required to inform her of this. Requesting a divorce because the husband married another woman is not permissible unless the wife fears losing her rights due to her jealousy. It is not permissible for the wife to demand the divorce of the other wife. The wife has the right to request a divorce if the husband does not provide the obligatory maintenance or any other right due to her.
