What is the ruling on marriage and divorce, and the consequent rulings concerning the dowry, after the sister agreed to marry a worker she employed, and after the contract procedures were completed and communication was made with the wife's family, it became clear that the one who approved the marriage was not her father but her sister's husband, then the husband divorced her under duress, and can one of the witnesses to the contract be authorized to communicate with the wife's family to obtain her father's consent?

The marriage contract that was concluded is religiously invalid due to the absence of the woman's guardian's consent at the time of the contract, which is what nullifies it. A telephonic contract is not valid because the marriage contract is a solemn covenant that requires the presence of the parties and witnesses, and the telephone does not guarantee verification of the guardian's identity or competence. Repentance and seeking forgiveness for this act are necessary, and the full dowry must be paid to the woman. It is permissible to marry her again with the guardian's personal presence or by an authorized representative, while observing the conditions for authorization in marriage.
