Does a divorce pronounced under duress take effect, and does the wife become unlawful to her husband because of this divorce? What is the solution for such a situation?

Threatening the wife and pressuring her husband is not considered valid duress. As long as the divorce took place in court, the wife must refer back to it to consider her claim of duress. The wife is now irrevocably divorced from her husband with a major divorce, and she is not lawful for him until she marries someone else. The husband's cohabitation with her before the court annuls the divorce is considered forbidden adultery.
