Can the mother reclaim land that the father sold without her consent, or must the buyer pay the fair price for the land?

A father's action of selling his daughter's share of land without her consent is impermissible and is considered an unauthorized sale (بيع فضولي) that is contingent upon the wife's approval. If she approves the sale, she is entitled to her share of the price. If she does not approve it, her share of the land remains her property. The buyer has the right to reclaim from the father the amount he paid for the wife's share. This website specializes in religious rulings (fatwas) and not legal matters. A Muslim should first seek the religious ruling and then inquire about legal procedures to avoid harm.
