What is the ruling on divorcing one's wife in American courts against her will, and is it permissible to take her back after that?

It is not permissible for the wife's family to interfere between the spouses except for reconciliation. Their efforts to divorce her without a legitimate religious reason are forbidden and considered incitement (takhbib). If the wife stipulated completing her education before the marriage contract and before the husband, he must fulfill it. It is not permissible to resort to man-made laws except out of necessity, and a divorce issued by them does not take effect religiously unless the husband divorces his wife with a religiously valid divorce and documents it. The wife does not leave your عصمة (bond of marriage) by a divorce from man-made courts. Custody is a right for both parents as long as the marriage is ongoing, and the wife's father does not have the right to force you to waive it or compel you to pay money unjustly. Continue to advise the wife's father, seek help from influential figures, and supplicate.
